The present invention relates to a wind system that is designed to convert the energy through at least one power wing profile. The present invention also relates to a method for generating energy by means of such systems, as well as the application of this system to tow the vessel.

As you know, in the past, the problem of generating electricity with low cost decided by the exploitation of renewable energy sources; in particular, some known patents, described below, suggests ways of converting wind energy, as well as the different devices that are selected wind energy through the power wing profiles (commonly referred to by the term "kite").

In particular, in U.S. patent 4124182 disclosed device with "a kite" (or "modified parachute") to capture wind energy and its conversion into rotational motion of the shaft that drives the generator. This device is distinguished by the pair of chains kite", in which the wing profiles are consecutive. Each chain is provided with a power cable. Such cables have sufficient length to provide the possibility to achieve chains kite altitudes where winds are stronger and more consistent winds from the oseney to the winds, that blow on the earth's surface level. Each chain through its corresponding power cable connected with the drum or winch, the direction of rotation of which can be changed to re-coiling cables or to allow unwinding of the cables due to the thrust generated by wind currents. Each chain kite comes with a second rope called a cable cover that is connected to each wing profile of the chain, whereby it is possible to selectively fold the kite to facilitate re-winding. Through the reduction gear rotational movement of each winch will be transferred to the generator, which, when it is powered, generates electricity. There is a single system of pulleys, which through the clutch and wheels provides the possibility that, when the string of a kite gains altitude, the other chain is returned. This is captured in the wind energy is converted into mechanical energy, which is in part will be spent to return the chain of a kite, a cap which will be shorted, and partly it is converted into electrical energy. By aerostatic globe associated with each chain, which in each working cycle inflate and down, kites hold is up to the desired height, when the cap is in a fixed orientation.

Chinese patent CN 1052723 disclosed a wind generator equipped with a pair of kites, through which the thrust created by the flow caused by wind, will be converted with the help of cables with high resistance, the rotation of the drum, located on the ground level. Winch drives the hydraulic motor, by which the generation of current.

In the United Kingdom patent GB 2317422 disclosed device, equipped with a large number of profiles of the wing, which due to the action of the wind rotates the vertical shaft connected to a generator for generating electric current. Profiles wing perceive pushing their insulating effect, doing a circular path in a horizontal plane. Each profile is equipped with a device that is able to change the angle of the binding to the wind, to ensure the continuation of the flight.

In patent United States US 6072245 disclosed a device for harnessing wind energy, composed of a large number of kites that are connected with cables, which form a ring. Kites lead in the movement to alternate the path of ascent and the path of descent, determining the rotational circular motion is always along the same voltage is Alenia. Each kite connect the power cable for the transmission of mechanical energy and drive system cables for regulating the snap angle to the wind each profile. Power cable determines the rotation of the pulleys, through which the production of electrical energy. The drive cables are used for making each a kite position of ascension allows you to pull the profile of the wing upward by the wind, and the second position in the path of the lowering, so that the profile of the wing is subjected to reduced wind pressure.

In patent United States US 6254034 disclosed device, equipped with a wing profile ("tethered aircraft"), pushed by a wind flow rate controlled to use wind energy. The profile of the wing is connected by means of a cable winch, which actuates a generator for generating electric energy. Panel profile collected the drive system, which detects and changes the angle of the binding to the wind, and modifies the front area of coverage by the wind. This system of land controlled by the operator, which reads the display data transmitted from the respective sensors, or it is done automatically by remote control system. Kite result in step, to ensure his ascension to the wind with a high angle of binding to the wind. After his ascension angle binding is reduced, and profile plans for its passage against the wind. The profile is returned, re-planning on the wind, and the cycle repeats.

In the Dutch patent NL 1017171 C revealed a device that is similar to the previously described device, but which is not provided with manual actuation, and in which the return profile of the wing is by inclination a kite, a flag, in order to minimize the pressure caused by the action of the wind at the back of winding ropes.

In patent United States US 6523781 disclosed a device consisting of a wing profile ("wind kite"), through which capture the energy created by the activity of the wind, having an input region, an output edge and two side edges. Such a profile trigger mechanism held by a kite. This device is equipped with cables, connected to the edges of the profile, and the kite is brought into action, changing through such cables the pitch angle. The drive mechanism is fed through electrical cables located inside the power cable that connects the kite winch, which activates a generator to produce electricity is energii. The wing profile is gaining height, pushed by the wind through the use of a lifting force, and describes the path nearly perpendicular to the direction of the wind speed. After the end of the climb kite is returned, after which it set in motion again to catch the wind.

In the application for patent of the United States US 2005046197 disclosed device, equipped with a wing profile ("kite") to use the energy created by the wind, which generates electricity through actuation using wire rope winch connected to a generator. Kite operate through additional cables through which change the snap angle to the wind. Profile gains altitude at high angle of binding to the wind. After completing the climb angle of the binding to the wind brought to a minimum and return profile in order to re-start the cycle.

Analyzing the existing level of technology, you can see that in the known systems mechanical components for actuation of a kite are different from components to produce energy, and the profile of the wing to operate through mechanisms, which are directly mounted on a kite, or by using at least four auxiliary cables, unwinding and povtoreniyami which is realized by means of winches, different from the winches used for generating electricity and managed by systems located on level ground or suspended above the ground, therefore, held by a kite.

In addition, many existing systems wing profile to give effect to generate electricity mainly through the use of drag (namely, the component of the pressure created by the action of wind, which is parallel to the wind speed). In other systems, the cycle of actuation of a kite differs continuous alternation of climb, which occurs through the use of the lifting force (namely, the component of the pressure created by the wind, which is perpendicular to the wind speed), and lowering that occurs by bringing the drag to a minimum.

In addition, in existing systems focus exclusively on opportunities for continuous generating electricity through a cyclic process, ignoring the possible implementation of systems that maximise energy that can be harnessed from the wind.

We currently generating electric power based on wind energy, occurs inside the mouth of the mode through fixed devices. Regarding the use of this renewable energy, there are no devices that can be moved and by which it is possible to produce an electric current in any place where the wind blows. Such potential could provide a huge advantage in those cases in which the current production currently occurs exclusively through inextricably groups (fuel-powered engine and generators), for example, in the field hospitals.

Currently, however, the problems associated with control systems for power wing profile, detail resolved in an extremely limited number of projects and studies, however, they mainly focused on improving the performance of existing systems instead of developing new systems for generating energy.

In the past, have also been proposed various devices related to towing vessels through devices that catch the threads created by the wind using power profiles of the wing.

In particular, in the United Kingdom patent GB 2098951 disclosed a device for towing vessels through the chain of power wing profiles. Run profiles occurs, starting with the launch of the pilot profile, which raises a couple of cables, acting as guides to run other prof is lei. Guides the cables to unwind until all power profiles do not reach the desired height. In order to prevent the fluctuation profiles at startup, some of them lowered or pulled before deploying to capture flows generated by the wind. After all power profiles reach an acceptable height, the ascent ends, and the pilot return profile or pull into a tube that is designed to store and located in the head part of the chain of power wing profiles.

In patent United States US 5056447 disclosed a device for converting energy generated by the wind into mechanical energy through a system consisting of sails, located at different altitudes, with their concavity is oriented in the lower direction. This device acts as a power wing profile subjected to the pull effect through the ascending flows generated by the action of the wind. This device can be applied to the earth, water or air transport, on the rails or for generating electric energy by means of rotating blades, which actuate the generator.

In patent United States US 5435259 disclosed a device for use wind flows at high altitude to produce electricity or tow t is unsporty tools on the ground or on the water. A passenger on Board the vehicle actuates a system consisting of a power profile of the wing, which behaves as a normal glider. Vehicle acting as a movable anchor, equipped with a control system preventing the overturning of different managing rope wrapped around the Central section of the vehicle, and a rod which passes over both sides of the vehicle. This rod looks like a section of rail that pushes the lower end of the rope that secures the power profiles to the vehicle, away from the sides, passing wind, thereby allowing you to avoid them tipping over. The power profile is equipped at its upper end a cylindrical aerostatic balloons for holding the load, if there is insufficient wind. Such balls on their ends have additional wind turbines, by means of which produce electricity.

In the international patent application WO 03097448 disclosed a device for towing vessels through the power wing profile. This device has at least one "control cable"through which the wing profile connect with hull. Place of application of force transferred through the control cable (cable) to the hull varies depending on which of the ETP along the direction of advancement of the vessel. A place of application of force actually slips inside perimeter of the guide mounted on the hull of the vessel to reduce the roll.

In the application for patent of the United States US 2004035345 disclosed a device for actuation of the power profile of the wing, attached to the vessel through at least a pair of "suspension cables". The management tool wing profile contains a rail that runs horizontally under the surface of the water, and on which is mounted the device to discard the suspension cables, which can slide along the rail. This guide is connected with the hull between power wing profile and system, through which the profile trigger, so that the thrust provided by the wing profile, creates a moment around the longitudinal and/or transverse axis of the vessel in the water through which the vessel is located in the wind will be pushing the exposure in the upper direction.

In the application for patent of the United States US 2004200396 revealed three ways through which you can create axial force at the base of the vessel to ensure its promotion on the surface of the water. The first method consists in placing the sail on the aft and tilt to the wind (outside the vessel)to create an axial pressure. The second way is to use the power wing profile, PR is fastened on the nose and driven to flight up and ahead of the vessel, creating thrust, which propels the ship. The third way is to use the keel, equipped with a wide flat plate, inclined upward to move through the water, creating axial pressure, which tends to lift the body. This patent also disclosed a rotating sails, made from strips of fabric, which pass through the frame having a lattice form. These sails are made in order to counteract the streams created by the wind, if they will be provided with a pushing action to the grid, and they provide passage of wind, when the latter is blowing along the opposite direction, leading to waste strips of fabric from the frame.

In the international patent application WO 2005100147 disclosed a device for towing vessels through the power profile of the wing attached to the body by means of a cable. Such a device is used as applied in exceptional cases, auxiliary or emergency guide site. The system is equipped with a winch, which contains the means by which the cable is repeatedly wound and unwound. Re-winding perform when the pull rope is insufficient, or when the wind speed decreases sharply. The unwinding of the cable is performed when the load on the cable and/or the wind speed is excessive.

In the international application on the Pat the t WO 2005100148 disclosed a device for towing vessels through the power wing profile, attached to the housing by means of a cable. Such a device is used as applied in exceptional cases, auxiliary or emergency site. The wing profile is brought into action by means of a control device, which gives the profile direction, allowing it to move in a helical or sinusoidal trajectories that pass along the vertical direction with respect to the streams created by the wind, and the velocity vector perpendicular to the wind speed. Different trajectories or static conditions of the flight chosen by the control system, whereas the rate, direction and speed of wind, and the movement of the sea.

In the international patent application WO 2005100149 disclosed a device for towing vessels through the power wing profile. Such a device is used as applied in exceptional cases, auxiliary or emergency site. The profile of the wing is connected with the vessel by means of a cable, which comes in the form of end splitting sequence of cables in the vicinity of the wing profile. The drive system held by means of a wing profile and connect with it, changes the angle of the binding to the wind in order to adjust the position of the wing profile in relation to the vessel.

In the patent application DE 102004018814 Germany revealed the device to tug the of vessels by power wing profile, attached to the housing by means of a cable. Such a profile can be powered by means of apparatus which can be installed in azimuth, and which may be withheld by the profile of the wing, and by means of which the profile gives the direction from the vessel. The device is also equipped with a receiving system, which keeps the profile of the wing when the system is not powered and automatically include devices with which the profile is lowered.

Therefore, the aim of the present invention is to solve the above problems of the prior art by creating a wind system for converting energy through at least one power wing profile, in which the mechanical components of the profile of the wing to bring it into effect not differ from components to produce energy.

Another objective of the present invention is to create a wind system for converting energy through at least one power wing profile, in which the profile is brought into action by means of intelligent control systems, which each work cycle provides for the passage of the wing profile best ways to optimize energy, which can be selected in the wind.

Another objective of the present image is the shadow is to create a wind system for converting energy by, at least one power wing profile, in which the difficulties associated with its components arranged on earth is so limited that their transportation is also possible using a conventional self-propelled vehicle.

In addition, the purpose of the present invention is to provide a method for generating electrical energy through wind system according to the invention, which can be powered more efficiently with respect to what is proposed in the prior art.

The above and other objectives and advantages of the invention, which will become more understandable from the following description, are achieved by means of a wind system for converting energy through the power wing profile, which stated in paragraph 1 of the claims.

In addition, the above and other objectives and advantages of the invention achieved through a method of generating electrical energy through wind system according to the present invention, which is stated in paragraph 24 of the claims.

Preferred embodiments of, and no obvious changes of the present invention constitute the essence of the dependent claims.

If you look at the figures, we can see that Vetrova the system according to the present invention contains:

at least one power profile 30 of the wing, which can be powered from the ground (hereinafter it will be called by the term "kite"), immersed in the wind. The profile of the wing is made by woven fibers commonly used for the manufacture of special sails for certain types of sports activities such as surfing and karting. The main characteristic which distinguishes a kite, is the surface area. Thanks to a recently conducted research in the field of aerodynamics on the market can be purchased profiles of the wing, which can satisfy certain requirements in respect of management and the possibility of putting them into effect. By proper enforcement of the wing profile in action can modulate the energy transfer from the wind. In particular, it is possible to send the kite 30 flight trajectory, moving it from the position in which the thrust provided by the flow-induced wind, in which are immersed the profile 30 of the wing, maximum, in a position close to the stall (which may be in azimuth or side), in which such a pull is minimal. By a cyclic alternation of maximum thrust stage and the stage, close to the stall, and subsequent return,will be the production of electrical energy, below will be described in more detail :

the base platform 1, which is designed to actuate the profile 30 of the wing and to convert the energy of the flow-induced wind into electrical or mechanical energy, which is located on the ground level and connected via two cables 2 power profile 30 of the wing, with two ropes 2 are used for transmitting forces from the profile 30 of the wing and to him, and both of them are used to control the flight path of the profile 30 of the wing and energy transfer methods, which are listed next. This can be achieved for many power profiles 30 of the wing, connected in series with each other to summarize the thrust force, attached to the cables 2. Profiles 30 of the wing is actually connected with the base platform 1 um 2 cables. For simplicity, hereinafter, will be referred to the case in which the wind system according to the present invention is provided with a single profile 30 of the wing. The principle of operation of the wind system according to the present invention does not actually depend on the number of profiles used 30 of the wing. The advantage derived from the use of a large number of power profiles 30 of the wing, is to increase the surface wind front, crossed with such profiles and, consequently, to increase traction on the winches 3 and HC is the chances of improving electrical energy, you can develop during each working cycle, which will be described below in more detail.

In addition, the system according to the present invention includes an intelligent control system acting on the base platform 1, by means of which the flight profile 30 of the wing is automatically controlled and the system 12 power supply, interacting with intelligent control system to control the accumulation and supply of electric energy.

Intelligent control system interacts with a group of sensors with self-contained means for supplying, located on the profile of the wing 30, which preferably sends information wirelessly to a ground-based components of intelligent control systems. Intelligent control system combines these pieces of information with other information coming from the set of ground sensors (for example, with the magnitude of the load on the cables defined by the read engine torque), and performs processing for automatic actuation of the profile 30 of the wing during the whole working cycle.

If, in particular, refer to figures 1 and 2, we can see that the base platform 1 contains at least two winches 3, each of which is wound or each of which is unwound appropriate cable 2,while each of these winches 3 are combined, it is possible, through the introduction of at least one of the gear 4, with an electric generator/motor 5. Near each winch 3 is a guide module 6, which enforces ordered the winding of each cable 2 to the corresponding winch 3, and transmission system that sends every cable 2 to the profile 30 of the wing. When this profile 30 wing operate through unwinding and re-winding of the cables 2 to the corresponding winch 3. In this case, the cables 2 are the connecting element between a kite 30 and the base platform 1, and provide the transmission of force between a kite 30 and winches 3. When the kite 30 is lifted by the wind, ropes 2 determine the rotation of the winches 3 and, consequently, the transformation of energy by the generator 5. Instead, during the return of a kite 30 cables 2 are passed to the profile 30 of the wing tension generated by the rotation of the winches 3 through engines. Obviously, the length and diameter of each cable 2 depend on the wind and the security environment in which to work with.

The transfer system contains blocks that accompany the 2 cables through the pulleys. In the preferred embodiment shown in the figures, the transfer system, in particular, consists of the following:

the first pair of blocks 7 is, collected on the sliding blocks 6A of the guide units 6 cables 2;

the second pair of blocks 7b, located further downstream from the guide units 6 cables 2 and intended for holding the horizontal sections of the cable 2, prisoners between the blocks 7b and those that are installed on the sliding blocks 6A of the guide modules 6;

the third pair of blocks 7d intended for guiding cables 2 to the profile 30 of the wing;

at least one pair of weakening mechanisms of abrupt load changes introduced 7b between the second and third 7d a couple of blocks; each of these mechanisms comprises at least one elastic element 17, such as an elastic rope or spring, which is near one of its ends 17A attached to the base platform 1, and at the other end it communicates with a section of rope 2 further downstream from the guide module 6, and the elastic element 17 may direct between the two ends of the fifth unit 7E. The interaction between the elastic elements 17 and cables 2 and occurs through the introduction between them of the fourth block 7C. When the wind blows, the elastic elements 17 are stretched, softening the sharp change of the load. On the contrary, if the load suddenly decreases, the elastic elements 17 are compressed, partially compensating for the delay with which the intelligent control system, isanna below, in effect, in order to adapt to the reduction of tension. The transfer system shown in the figures, is preferably provided with two mechanisms for attenuating sudden load changes, one near each winch 3.

The transfer system further comprises a pair of tensioning devices 18, one for each cable 2, located between the mechanisms of attenuation of sudden load changes, and the third pair of blocks 7d, which accompany the cable 2 to the profile 30 of the wing.

If we turn to figa and 3b, we can see that the device 18 is composed of the first 19a and 19b of the second pulleys, which are facing each other, having co-planar with the axis of rotation. Pulleys 19a, 19b are rotated around the respective first 20A and second 20b rotary fingers, and inserted between the two grippers 21. In particular, the first rotary finger 20A slides within a pair of slots 22, made in the grips 21, the distance from the second rotary stopper 20b is not constant and may vary. The first 20A and second 20b fingers can be further interconnected by means of elastic elements, such as a pair of springs 23, each of which is in the vicinity of each of the grip 21. The tensioning device 18 is fixed to the base platform 1, for example, by a rod (not shown)held within the holes 26 of the grip 21. Size is s pulleys 19a, 19b and the stiffness coefficient of the spring 23 is such that when the load on the cable 2 is missing, two pulleys 19a, 19b are located in the first position similar to the position shown in particular in figure 3, in which they come into contact with the cable 2, and slowing pastophoria it. If the wind stops when the profile 30 of the wing is in flight, the tensioning device 18 will prevent slippage of the cables 2, keeping them under tension due to the action of elastic pulley cables 17 mechanism of weakening of the abrupt load change. Instead, when the unwinding and re-winding of the cables 2, the load will be such that the springs 23 will provide relative movement of the pulleys 19a, 19b in the direction of guaranteeing the normal rolling of the cable 2 on the first pulley 19a. The transfer system shown in the figures, is preferably provided with two tensioning devices 18, one near each winch 3.

Blocks 7a mounted on the sliding blocks 6A of the guide units 6 2 cables, blocks 7b, located further downstream from these modules 6, and a pair of blocks 7C mechanism of attenuation of sudden load changes have fixed heads, while in other blocks of the head can turn freely. In particular, in block 7d, which accompany the ropes to the profile 30 of the wing, you can perform a pivotal connection with the base platform is 1, created by at least one of the spring 25. This provides considerable freedom of rotation, and this requirement is fundamental for the maintenance of the cables 2 to the profile 30 of the wing when the system according to the present invention.

Guiding units 6 are components of the base platform 1, which enforce orderly winding ropes on the winch 3 and prevent sliding between the ropes 2 and seizures winches 3, and between the cables 2. Each guide module 6 equip the slide block 6A, which slides along the rail 6b, located parallel to the axis of rotation of the respective winches 3. The slide block 6A can perform translational movement in two directions along such rail 6b, and on it is mounted the first block 7a. In particular, the sliding block 6A is controlled by a sliding mechanism (not shown), which provides that the slip together with the rotation of the winch 3. Preferably, the sliding mechanism could be set in motion by means of a screw or belt. In the case of the sliding mechanism, which is driven by the screw forward movement of the slide block 6A along the rail 6b is controlled by rotation of the ball recirculation, precision screw. In the case of the gliding mechanism is, driven by belt, the slide block 6A is mounted on the toothed belt.

In the guide module 6 cables 2 translational movement of the slide block is managed by at least one electric motor (not shown), which acts on the sliding mechanism, which controls the intelligent control system that controls the profile 30 of the wing.

The system according to the present invention is preferably equipped with two guide units 6 2 cables, one for each winch 3.

Winch 3 are components, provided with a collar, around which is wound the cables 2. Winch 3 is connected through intermediate gears 4, preferably epicycle type, with the generator/motor 5. Thus each rotation of the winch 3 is connected with the rotation of the corresponding drive shaft. During the stage of generating electricity is the uncoiling of the 2 cables from the winch to rotate the winch 3. Instead, during the reset profile 30 of the wing engines lead winches 3 in action. The device contains two winches 3, one for each cable 2.

Generators 5 are components through which the production of electricity. Their actuation is realized by means of winches 3 when razmityu the research Institute of the cables 2. In the system according to the present invention generators 5 also act as engines, performing repeated winding 2 cables on the winch 3, when it is necessary to return the profile 30 of the wing. Control of the generator/motor 5 is carried out by means of intelligent control systems in modes which will be described below, the system according to the present invention is preferably equipped with two generators/motors 5.

The intelligent control system is a system by which automatically actuate profiles 30 of the wing. The main objective of this system is to control the operation of the generator/motor 5 and, therefore, in the rotation of the winches 3. Actuation of the profile 30 of the wing actually occurs through regulation of unwinding and re-winding of the cables 2 to the same winch 3, by means of which produce energy. While the 2 cables that connect the profile 30 of the wing with the base platform 1, represent the power cables and transmission cables. The development of energy depends on the direction of rotation of the winches 3: production of electricity occurs when the rotation of the winches will be determined by the pull of the cables 2 and is to ensure that generators 5 in action. Instead, it is spending the Finance energy when the rotation of the winches 3 defined by the engines and re-coiling cables 2. Actuation profile of the wing depends on the direction of rotation and speed of rotation of the winches 3. The profile 30 of the wing actually is driven by a corresponding change in the snap angle to the wind. This angle depends on the position of the profile 30 of the wing in relation to wind speed and, consequently, the length of each of the two plots unwound the rope 2. If, for example, for adoption by the profile 30 of the wing of some of inclination necessary to shorten the length of the cable 2, unwound with respect to the other rope to get this result, you will need to speed up or slow down the rotation of the winch 3 in relation to the other winch. Therefore, without reducing the energy produced or return the profile 30 of the wing actuation profile 30 of the wing occurs through differentiation of the speed of rotation of the two winches 3. Automatic control of the flight profile 30 wing perform through a set of control algorithms, with which the profile 30 of the wing to give effect to avoid oscillations, instability when actuation and local maximum traction. The trajectory path or flight performed by the profile 30 of the wing, I expect to optimize energy created during the cycle of operation at maximum security with maximum compliance in relation to the dynamics and process of minimizing the time required to pass from the current position to the predicted position. An automatic adaptation of the profile 30 of the wing in the action happens through a process that runs in real time, which is receiving and processing information received from a set of ground sensors and on the profile of the wing 30, which may be necessary to pre-process the data so as not to overload the connection with the ground-based components of intelligent control systems primarily in the case, if such communication is carried out wirelessly. Incoming information refers to the position of the profile 30 of the wing, accelerations, forces (for example, to the load on the cable, defined by the read engine torque 5) and geometrically-defined values. Intelligent control system carries out the processing of input signals through a set of algorithms and generates an output signal which actuates the generators/motors 5, connected to the winches 3.

Processing of incoming information requires time interval, which is proportional to the duration of the data analysis. By bringing to the minimum duration of such online who tore delay, which actuate the profile 30 of the wing will be reduced. For this reason, has the advantage of short-term analysis. However, short-term analysis may not allow to predict the path with the optimal duration of time. Therefore, it is important to give priority to the optimal compromise solution, so that the data processing took place in a short time, but sufficient to obtain the optimal path length. However, it is reasonable to assume that creating a path that is longer than the path described during the working cycle, it is useless.

A prediction algorithm implemented by the intelligent control system, in each case determines the optimal position that the profile 30 of the wing should take in the next moments through the appropriate flight and control parameters (altitude, dynamic counterweight, pull data, calculation of security in restricted areas, location of structural stress, instability or excessive force, moments, which must be fulfilled actuation, ...). Each parameter for any point in time corresponds to the coordinates of the optimal position (parameter)that the profile of the wing must take at some point. Determine the relative weight of each parameter, which is the distance between the first point through a retroactive system, which adjusts the weight of the most critical parameters in order to decide which parameters are more important. Once collected the best coordinates for each parameter, define the vector sum for each point in time to justify the prediction. Finally, after the introduction of the significance of time when prevailing short-term strategy, for each time calculate the optimal coordinates. Once provided with the ideal coordinates of the provisions that the profile 30 of the wing should take in the subsequent moments of time, are performed in real time, the process determines the best path should follow the profile 30 of the wing to achieve these provisions. The algorithm used for this purpose, use equation flight, the inertia of the profile 30 of the wing and share the reactions that it can be depending on the difference of the pull on the cables 2, to determine the law to bring the profile 30 of the wing in action. Through appropriate means to control the actuation carefully verify to eliminate the risk of fluctuations and excessive gain due to inertia, elasticity of the kinematic chain and the necessary delay.

Control over the rotation of the winch 3 is not the only function of intelligent control system. Like what about the earlier, the system is also responsible for the actuation of the guide units 6 cables 2. Engines that operate such modules by working on their mechanisms of slip control in order to properly link the rotation of the winches 3 with the translational motion of the blocks 6A sliding guide module 6. Therefore, through the intelligent control system the speed and direction of translational movement of the sliding blocks 6A regulate to force, ordered the winding 2 cables on the winch 3, as well as to prevent slippage between the 2 cables and clamps winches 3, and between the ropes.

Finally, the intelligent control system should recognize events such as wind gusts and load shedding, and timely adapt to them. In the case of wind gusts intelligent control system shall come into effect by reducing the tension of the cables 2, to prevent damage to the system from overloading. This is carried out by actuation of the winch 3, to provide a rapid unwinding of the cables 2.

The sharp drop in the load has to be avoided because of insufficient tension 2 leads to the throws of the profile 30 of the wing without any possibility of control. If there is a falling load, intelligence of the social control system carries out intervention by accelerating the rotation of the winches 3 (in the case when this happens during re-winding) or by changing their rotation on the back (if the drop in load occurs when unwinding). Thus, the activation of the return profile 30 of the wing.

Power supply system contains all necessary components for accumulation and supply of electric energy. In particular, the power supply system equipped with power supply, transformers and batteries, through which there is accumulation of generated electricity when unwinding the cables 2, the flow of current to the motor 5 when you return profile 30 of the wing, the power electronic components according to the present invention and the flow of electrical energy to the possible external customers.

All electronic components of the system according to the present invention is controlled by intelligent control systems in cooperation with the power supply system.

From what is said above, it is obvious that in relation to what is proposed in the existing prior art, the system according to the present invention provides a new method of controlling the profile 30 of the wing, because there is no difference between power cables and power cables, and both of these features provide only via two cables 2. So there is one pair is Bedok 3, operate the generator 5, which also act as motors. While in existing projects return a kite carried out by the same winch with which ensure the production of electricity, in the system according to the present invention this is done through the same winch 3, which also actuate the profile 30 of the wing, not just returns. Angle to the wind and the square of the wind front, crossed a kite 30, is controlled by regulating the length of the plot unwound the ropes 2, to maximize the flow of energy when you set the height of the profile 30 of the wing, and the minimum energy consumption during the phase of return.

The present invention also relates to a method for generating electric energy through a wind system that is similar to the previously described system. In fact, the method according to the present invention, which in General is a method of converting wind energy into electrical energy through wind system according to the present invention is a method of intermittent type. If, in particular, refer to figure 4, we can see that the method according to the present invention contains the following steps:

a) management of the F1 trajectory p is the summer of the profile 30 of the wing is preferably automatically by means of intelligent control systems so that energy, which may be taken from the wind or the flow W, provided by the wind maximum. In particular, the intelligent control system actuates the profile 30 of the wing to use the "lift force", namely, the component of force perpendicular to the velocity W of the wind. When this profile 30 wing gains altitude, continuing to scan the surface of the wind front. Therefore, the wind provides the set height of the profile 30 of the wing, pulling the wires 2 connected to the base platform 1: this rod is converted into rotation at the level of the winch 3, which through a reduction gear 4 is transmitted to the generator 5, which by means of a prize due to a pair of forces that are opposite, is the production of electricity;

b) actuation F2 profile 30 of the wing, preferably automatically, by means of intelligent control systems, to reach a position close to the stall, near which the pressure caused by the action of wind, insufficient;

c) re-winding F3 2 cables on the winch 3 by engine 5, which also act as generators. The rope 2 is wound with minimal energy consumption, and after return cables 2 profile 30 of the wing will be located so as to ensure its return to a state of maximum rod is;

d) subsequent repetition of the process.

The energy produced during the unwinding of the cables 1, greater than the energy spent on re-winding. Therefore, the energy balance is positive.

Through the use of the method according to the present invention and with intelligent control system, which in the real time processing information coming from a group of sensors installed on the profile 30 of the wing, and a set of ground sensors can be powered profile 30 of the wing, to provide them the height mainly through the use of the lifting force. In this way, you want the profile 30 of the wing during each cycle of execution of the process will be optimal in terms of energy that can be taken from the wind when travelling in such ways (for example, when a sequence of eight)to cross the maximum air volume. Therefore, the method according to the present invention not only guarantees consistency in relation to generating electricity, but also the optimization of energy that can be obtained during each cycle with the same size of the profile of the wing relative to known systems.

To prove the high efficiency demonstrated wind system and method according to the present from which bretania, and just as an example, assume that the wind velocity Vwthat profile 30 of the wing must be able to withstand (i.e. without damaging its components)is 6 m/sec. Let's further assume that the maximum velocity Vswhere is the unwinding of the cables is 4 m/sec. The profile 30 of the wing varies freely through the "scan" the surface of the wind front, and when casting profile 30 of the wing in action in this way will receive a rate considerably larger greater than the wind speed. In particular, suppose that the ratio of the velocity Vkprofile 30 of the wing to the wind velocity Vwis more than 10. If the maximum wind speed Vwis 6 m/s, the maximum velocity Vkprofile 30 of the wing will be 60 m/s. Not surprising that the maximum velocity Vsreeling cables 2 has been taken equal to 4 m/sec, while the maximum speed of the profile 30 of the wing is 60 m/sec. In fact, the profile 30 of the wing, like a normal kite, can continuously change its direction without compliance with such changes rapid unwinding of the cables 2.

Further assume that the length of each cable 2 at the same time, in which after unrolling the profile is captured by the wind, is 80 meters, and that rod is, created by the flow caused by the action of wind, leads to unwinding of the cables is approximately 200 meters.

Assume that the rate of unwinding is 4 m/sec, and the development of energy occurs for 50 seconds per cycle [200/4 m(m/sec)]. Assume that the other 4 seconds necessary to ensure that the profile 30 of the wing took a position close to the stall (in azimuth or lateral). In particular, during the first seconds will still be unwinding cables 2 with an average speed component of 2 m/sec. In the last three seconds, the unwinding will occur at an average speed of 4 m/sec. In General, during the stage of passage to a state close to a stall, there must be an unwinding of the cables about 2 meters [2·1 (m/s)s] and re-winding 12 m [4·3 (m/s)·s]. At the end of this stage the length of the cables 2 should be 270 meters (280+2-12). Now starts winding in which the cables will be taken back to the originally approved length of about 80 meters. If re-wrapping occurs at a rate of 8 m/sec, it will take time, constituting 23,75 seconds [190/8 m/(m/s)].

Now is described the duty cycle corresponds to a hypothetical standard cycle of the method according to the present invention, in which the length of the cables shall not be less than 80 IU the ditch. It is obvious that you also have a starting cycle, during which you must manually unwinding estimated 80 meters of cable (passing in the direction from the base platform 1) and to ensure the capture of a kite wind flows. This first cycle is used not to generate electric energy, and in order to bring wind system in its operational state.

In all cases, references to the previous example for security purposes, the maximum length of each cable 2 must not be shorter 318 meters. In fact, it can be assumed that there may be gusts of wind, equal to 12 m/sec with a duration of 4 seconds; to prevent damage to the wind system can be assumed that in this case the speed of unwinding of the cables 2 is 8 m/s. A gust of wind must ensure that the unwinding of the cables 2, 36 ft [8·4 (m/s)·s].

Taking into account the re-winding of the cables 2, when there is a return to the position of the stall, and safe unwinding that occurs when the wind gusts, in the case of the described example, the maximum speed of rotation, which must withstand winch 3 should be equal (with respect to the cables 2) 8 m/s.

Now you can also do some analysis concerning the energy which the profile 30 of the wing is able to take away from the wind. For this purpose, and with reference to is first properly consider the aerodynamics of the system. It is known that when the wind flow occurs from the fixed aerodynamic surface ("aerofoil") AS this thread creates two forces: the drag D, parallel to the direction W along which the wind is blowing, and the lift force L, perpendicular to the direction W. In the case of laminar wind flow wind flow AF1passing over the aerodynamic surface AS will be faster than the flow AF2that pass below it, because they must cover a larger distance. This determines the pressure drop in the upper part of the profile and, consequently, the pressure gradient which creates a lift force L.

When considering 6 instead assume that the profile of AM can be moved along the direction DT of the lifting force. As a result of such movement of the lower surface of the airfoil AM to be inclined with respect to wind speed. In this case, the lift force and the drag will act accordingly perpendicular and parallel to the corresponding wind speed in relation to the profile.

When the notation S1forces parallel to the direction of motion, and S2forces perpendicular to this direction, the component of the lifting force L, parallel to the direction of motion, has the same meaning and steadily moved the e airfoil AM while the parallel component of drag D has the opposite meaning.

For this reason, the conservation movement along the perpendicular direction to wind flow, acceptable slope profile AM to get the highest component of the lifting force L along the direction of motion DT profile AM to the component of drag D.

These considerations are also valid for profile 30 wing wind system according to the present invention. Intelligent control system actually operates the profile 30 of the wing to maintain a high ratio of lift and drag during the stage of the climb profile 30 of the wing. When this profile 30 of the wing varies during scanning of the wind front and generates energy due to the pull of the cables 2. The energy produced during the climb profile 30 of the wing is calculated by multiplying the power density of the wind to the square of the wind front, crossed by the profile of the wing (i.e. the area of a kite), and the power factor of a kite KPF, and the efficiency depends on the ratio of the speed profile of the wing and wind Vk/VWand the two coefficients Todand K1(Kdrefers to frontal resistance, namely, when the kite pulls restraining his Holiness the relationship with the earth with the forces and velocities along the direction of the wind, a K1refers to lifting, namely, when the kite pulls limiting its connection with the earth vibrations to scan the surface of the wind front). As indicated previously, due to the lifting speed of the kite much more wind speed. The more power the kite, the higher the rise in relation to the drag.

For example, you can always assume that Vk/Vw=10; K1=1, 2, a Kd=0,1.

In this case, must be received KPF=20.

If we assume that the density ρ of the air is constant and equal to 1,225 kg/m3then the power density of the wind should be like this:

The power density of the wind =

"Power kite" is the power that can be generated by a kite, and which can be expressed by the following formula:

the power of a kite = KPF·specific power of the wind·A, where a is the area of a kite, which crosses the wind front. If, for example, use the profile of a wing with an area A=18 m2being pushed at a speed of 60 m/sec through the wind, blowing with a speed of 6 m/sec, then the power that can be obtained at the level of the cables will be 47628 watts. Consequently, such power would correspond to the maximum power that can make us what's snakes.

The value taken KPF, one way or another, depends on the efficiency of the wing profile. You can make KPF took values greater than 20. If, for example KPF takes a value of 40, then the maximum power that can be obtained from a kite with area equal to 18 m2will be 95256 watts.

If you refer to Fig.7, we can see that the wind system according to the present invention finds effective use in the field of navigation for towing vessels through the use of energy generated from wind.

In this case, all the previously described components of the system according to the present invention have a sailing or motor vessel 100. The transfer system, which contains 2 cables going to the profile 30 of the wing, located on the nose 101, while the profile of the wing 30 is brought into action so that he was always ahead of the vessel 100.

In contrast to the previously described application of the basic requirement of the wind system is not that it contains anything else to convert wind energy into electrical energy, and in the use of wind power to tow the vessel 100 and, consequently, the conversion of wind energy into mechanical energy.

Like the previous application, an intelligent system driven by what I've been programming for maximizing energy which power profile 30 of the wing is able to take away from the wind, in any case, avoiding that the load on the rope had become excessive and damage components of the wind system. The main difference from the previous case is that the use of wind energy is now not happening interruptibly. In fact, kite actuate not to alternate stages of the ascent stage and return to positive energy balance and to optimize continuous use of the flow caused by the wind. During the steady state return a kite 30 is solely in order to adapt to possible falling of the wind, or for adjusting the position of the profile 30 of the wing. Unwinding and re-winding rope 2 now is not the purpose of the circular formation energy, but only for actuation. Cables 2, through which the profile 30 of the wing connected with the vessel, can be considered as power and drive cables 2. Actuation occurs according to the same principle described for the previous application. The power transmission no longer takes place by actuation of the generator when the rotation of the winch, and as limited as possible what amativeness cables 2, so the vessel 100 to which the profile of the wing 30 is connected through the cables 2, is moved relative to a fixed coordinate system.

You notice how in both cases, the use of wind energy is associated with the promotion of the profile 30 of the wing in space. The difference is that if in the previously described device, the observer were a single entity with a fixed coordinate system (namely, with the earth), if applied to the vessel base platform 1 and the observer follow a kite 30 for his promotion.

In any case, you can ensure the production of electricity through wind system according to the invention, which is applied to the vessel 100. In fact, if necessary, moving the ends, similar to that described in the previous case, you can use the profile 30 of the wing to generate electricity. Intelligent control system in this case would be to impose appropriate restrictions on the flight profile 30 of the wing to prevent the occurrence of the cables 2 in contact with other components of the vessel 100.

Along with the previously mentioned advantages of the wind system and method according to the present invention provide other significant results in relation to what is already proposed in the known technical solutions, in particular:

Conversion of energy of on coming flow is provided due to electromagnetic induction appearing at self-excited oscillations in metal strings (flexible conductors) arranged in on-coming flow and placed in magnetic field. According to law of electromagnetic induction, metal string executing oscillatory movements in magnetic field becomes electric energy (current) generator.

EFFECT: increased power output of converter by increasing number of strings to required value.

SUBSTANCE: method of converting kinetic energy of wind which acts on fixed flying vehicle with transmission of mechanical power to working member located on the ground consists in the fact that there formed are two differently directed forces acting on flying vehicle, one of which pulls the vehicle up and is determined by the fact that the vehicle is lighter than air, and the other force is specified with its aerodynamic shape having the form of semi-sphere with lower spherical surface and upper flat surface. Besides it is possible to create additional force which acts during downward vehicle movement owing to the shape given to flying vehicle of asymmetric shape in the form of flat visor, which protrudes behind the ranges of perimeter of upper surface of flying vehicle, which activates vibration process.

EFFECT: conversion of energy of wind blowing even with low velocity to vibratory movement of working member with its further being used for electricity generation.
