The invention relates to the field of energy and can be used to convert the kinetic energy of a moving stream of fluid, such as wind, water moving in a stream, river, ocean currents, tides, or in the direction of flow into useful work, namely to generate electricity using the phenomenon of flutter, as well as to convert mechanical (electrical) energy of the engine into useful work vehicle traffic or fluid medium.

The search for effective means of conversion of renewable energy resources into useful work includes mechanical wind turbines (wind turbines), converting kinetic wind energy into mechanical energy with the use of lifting forces or forces of drag, mechanical and hydraulic turbines (generators), converting the kinetic energy of flowing water or the potential energy is raised to a height of stored water into mechanical energy. In most cases converted thus energy is converted into electric power for final distribution and use.

The shortcomings of the existing wind turbines and hydro generators are low efficiency associated with losses on the turbulization of air or water flow for the slave is CIMI elements (re), or ineffective kinematics re; limited range of the velocity head of the air or water flow; the presence of overturning moment and the associated difficulties during the installation of the wind turbines and hydro generators; environmental problems associated with construction and operation of wind turbines (high-frequency noise, interference, disruption of ecosystems) or hydro (dams, dikes, disturbance of ecosystems).

The conversion of the kinetic energy of the flow into electrical energy using converters propeller-type wind turbines, hydro turbines) worldwide recognized as ineffective (85% of the kinetic energy of the flow is spent on the turbulization of the flow and only 15% goes to useful work), environmentally unsafe (so-called "dead" zones for rotating blades, environmental issues) and very expensive (especially in the construction of hydraulic structures, dams and weirs). Worldwide the use of any renewable energy sources is unprofitable and subsidized. However, such sources of renewable energy, as ocean currents or surf while they do not lend themselves to use, while the energy potential from these sources is huge. So is reinforced by the search of more efficient renewable energy sources.

There are a number of technical solutions in this area (patent US 4184805, 09.03.1978,, patent US 4347036, epubl,, RF patent 2037641, 14.08.1991,, RF patent 2362907, 01.06.2006, (WO 2006/130719 20061207), in which the basis of expected use of the phenomenon of flutter for additional electrical energy.

Using the phenomenon of flutter caused by the desire to get out of the flow of any fluid more energy, which always accompanies the appearance of the flutter, and the magnitude of this energy can be very substantial (in seconds resulting in a sharp increase of dynamic loads and the destruction of working structures, such as aircraft or heat exchangers). And if you find a way to use this extra energy, you can get a very effective source of electrical energy. So many developers and try to work with flutter, in the event which there is the additional energy that can be used to produce electrical energy.

There is a method of converting the kinetic energy of the flow of fluid into useful work and the device for its implementation (see RF patent №2362907, (PCT publication: WO 2006/130719 20061207), IPC F03D 5/06, epubl,), which describes the method including placing the console installed re (cascade wings) in the fluid flow in terms of interaction with the fluid flow, when e is om ER set s, at least two degrees of freedom and serves the flow of fluid to pass through the cascade of re and forced excitation of resonant flutter oscillations, improvements include the installation of each re with individual suspension rod hinged manner and maintaining all of these suspension rods parallel to each other; maintain verticality and parallelism mentioned re, which is achieved by means of a mounting means providing rotational and translational motion with hard hold ER vertical and parallel with two charms on each wing; re connected through these suspension rods with hydraulic drive, by means of which the instantaneous motion control of these re (wings) offset and angle using an external controller to provide exact anti-phase motion of the neighboring ER and transfer energy from an oscillating ER to the battery; transmission of motion mentioned re carried out with a hydraulic drive for energy transfer them to the device for power (battery); in addition, provide hydraulic control of the transmission of such energy from the hydraulic actuator to the accumulator; provide the ability to convert e is ergie into electrical power; manage ER by creating a circular restoring forces and inertial mass to initiate and maintain resonance forced vibration flutter above re; to implement the described method uses a device containing a console re installed with the possibility of accommodation in the flow of fluid to provide at least two degrees of freedom, means for feeding a specified flow of fluid to pass through the ER, lots of suspension rods, each re is installed on individual hanging rod in the form of a console in parallel with the tools to maintain them in this position; in addition, the device may include a flexible element that is deformable under the action of the pressure generated by the specified fluid flow attached to the ER and runs along its back edge; possible version of the device, where each re is independent and is not associated with neighboring to minimize drag and vortex; in another embodiment, the device mounting means for maintaining re United in a single whole with the formation of easily removable and detachable modules, where each module is removable and replaceable without interrupting the adjacent wing; the device may include doctor is Ni rotational actuator control angle, located within bilateral linear actuator and pump so that the movement of one or many user's manual, United with the specified module actuator and pump using one of these hanging rods, provides independent and simultaneous movement of both transverse and rotational axes; re can be performed with rounded end portions on the leading edge to minimize drag, flaps formed on their ends; a deformable flexible division is made along at least the rear edge to change their curvature at extreme angles of the wing.

The main disadvantage of this invention is the low efficiency of conversion of kinetic flow energy into useful work associated with small amplitude oscillations ER, limited possibility of a forced resonant oscillations of neighboring ER, due to the distances between neighboring ER, at the optimum value of which there is a possibility of occurrence of the conditions of resonance oscillations of all ER (subject to availability and other variables such as the density and the critical flow velocity, the coincidence of the own frequencies of ER with the frequency characteristics of the flow, the elastic properties of the material, the conditions of consolidation, cash is Chiyo external disturbances and so on). Low conversion efficiency due to loss of kinetic energy of the fluid flow (or loss of flow velocity at the exit of the device compared with the flow velocity at the inlet of the device)associated with the turbulization of the flow and its interaction with the oscillating ER, losses associated with partial use of the gained useful for damping the energy of motion of the pistons to each manual when the piston stop and change direction, to maintain the parallelism of each OM, installation and maintenance of anti-phase motion of the neighboring ER, to create a circular restoring forces to initiate and maintain resonant oscillation.

The laws of rotational and reciprocating movement of each ER-dependent unsteady aerodynamic / hydrodynamic forces and moments arising from the interaction of fluctuating re with the fluid flow, so these movements are not harmonic, the laws of their different, there is no repetition of these movements in time, they can only be controlled, but it's almost impossible to control.

The disadvantages described of the invention is the volatility and complexity of control offer an oscillating resonant system, constantly requiring external disturbing forces for vazbu the conduct and maintain resonant oscillation, requiring constant adjustment, intervention and adjust each parameter of each oscillating re both rotational movement and for reciprocating movements.

The fall of the kinetic energy of the flow for re caused by the turbulization of the flow and its interaction with the oscillating ER in the case of excitation of resonant perturbations, making it impossible to increase the shooting of electrical power due to the extra manual or devices before considering re or behind them.

Also known that the closest structural features of the claimed device convert the kinetic energy of the fluid flow into useful work and implemented the method of converting the kinetic energy of the flow of fluid into useful work (patent DE 3616350 A1 (VOGEL EDWARD) 19.11.1987). Unlike described above analogues technical solutions electricity production in this device without using the positive influence of the phenomenon of flutter.

The method of conversion of the kinetic energy of the flow of fluid into useful work includes placement of ER in the fluid flow in terms of interaction with the fluid flow and the simultaneous message re harmonic rotational and reciprocating movement, while using the e, representing rigid frame structure in the form of two horizontal beams, it is fixed to the ends of two rods connected at the middle part with floaters, and hard counters, and the opposite ends to the crankshaft, reciprocating movement of the manual exercise on elliptical trajectories, the direction of the reciprocating movement of the axis of the connection of the middle part of the rod with the slide produced in the plane perpendicular to the direction of flow, and rotational movement re carried out with respect to an axis of the connection of the middle part of the rod with the slider.

Implementing the described method, the device convert the kinetic energy of the fluid flow into useful work performed single or multi-module, each module which contains the possibility of accommodation in the fluid flow ER mounted on a fixed base and fixedly mounted on two rods crank mechanism, floaters, which are connected with rods using axes and have the opportunity to make a reciprocating movement along the guide rails and the connecting rods pivotally connected to the cranks fixedly connected to the crankshaft, which, in turn, pivotally connected with a fixed base and is designed to transfer the energy of rotation the crank on device for PTO, this manual is a rigid frame structure in the form of two horizontal beams mounted on two rods connected in the middle part of the hard counters, and the opposite ends to the crankshaft; re is the possibility of rotational movement relative to the axis of connection of the middle parts of the connecting rod with sliders; ER has the ability reciprocating movement along elliptic trajectories; the direction of the reciprocating movement of the axes of connection of the middle parts of the connecting rod with sliders occurs in the plane perpendicular to the direction of movement of the stream.

The authors described the invention have relied on the conversion of the kinetic energy of the flow of air into electrical energy only due to the aerodynamic lifting force, eliminating any possibility of flutter. To address the issue of converting the kinetic energy of the stream into useful work they came only from the standpoint of aerodynamics, ignoring the unsteady aerodynamic processes and theory of forced oscillations. By increasing the mechanical damping of the whole structure (fixing ER on two hard poles connected in a rigid frame structure), the authors of this invention have significantly improved mechanical damping of the oscillating system, Garanti is consistent eliminating any possibility of flutter. And the use of resonance in the oscillating system, the authors eliminated by introducing into the mode of action of restrictions on the increase of the amplitudes of the reciprocating oscillation ER (any increase in the amplitude of the reciprocating oscillation of ER leads to a significant increase in the metal content of the whole structure and the periodic change of 12° of the phase angle between the disturbing force and displacement (at the resonant oscillations of the phase angle equals strictly 90°).

The main disadvantage of this invention is the low efficiency of conversion of kinetic energy of the fluid flow into useful work associated, first, with periodic motion re against the direction of movement of the fluid, which reduces the efficiency of the device; second, to implement positive work only aerodynamic lifting forces generated periodically and depending on the profile of ER and a very narrow speed range of the flow, which also reduces the efficiency of the device; third, small oscillation amplitudes, depending on the angle of attack re (maximum 12°), the geometric parameters of transmission mechanisms and purposes of the invention (small dimensions and small footprint of the device).

Significant disadvantages of the invention are also large metal is a technology device, due to the length of the rods, a significant shift of the centre of oscillating masses and, most importantly, intermittent dynamic blows and jerks caused by periodically changing the direction of movement of ER relative to the direction of flow and periodic changes of the points of application of the aerodynamic lifting force on the surface of the ER. To keep the whole structure in a healthy state required massive swivel bracket designed also serve to prevent from tipping over in case of occurrence of impulsive or Skalnik winds, which is especially important when placing the device on the roofs of houses. Particularly relevant this question with a vertical arrangement of the crankshaft. But placing a solid working product with significant variables dynamic load operation, is strictly prohibited on the roofs of buildings, especially tall buildings, and is another significant drawback of the prototype.

Another essential disadvantage of the described device is the formation of vortices of the fluid when exposed to aerodynamic lifting force on any design (or construction). Moreover, this phenomenon further reduces the efficiency of conversion of kinetic energy by the eye into useful work, as part of the flow energy is spent just on the formation of vortices, but with a vertical arrangement of the crankshaft, the periodic breakdown of vortices with working elements arranged on the first flow, causing chaotic unmanaged vibration in the working elements arranged on the second stream (the so-called buffet), which also leads to lower efficiency of this device. In addition, the turbulization of the flow of fluid leads to the loss of its kinetic energy, growth resistance and the emergence of overturning moment, the prevention of which also leads to increased size and weight swivel bearings.

Technical effects of the proposed method and device to convert the kinetic energy of the fluid flow into useful work, United by a single inventive concept, is the ability to generate electricity by creating a self-excited self-oscillations of the "flutter" and use positive work of unsteady aerodynamic forces and moments (unsteady aerodynamic effects UAI)arising from the interaction of the device with one oscillating re and with lots of re, in addition aligns the working speed of the flow at the inlet and outlet of the device, and, as a consequence, there is no tilt is the second moment resulting in a possibility of obtaining electric energy from any of the fluid flow with virtually no loss of kinetic energy of the flow, without disturbing the ecological system in the place of installation of the device, without the construction of complex hydraulic or mounting structures, reducing the metal device, the possibility of increasing the capacity of the device by attaching additional ER or more similar devices to a device directly in front of him or behind him, i.e. increasing the capacity and efficiency of the device and improving the reliability of the device as a whole.

To obtain these technical effects in the way of converting the kinetic energy of the flow of fluid into useful work, including the placement of re in the flow of fluid in the conditions of interaction with the fluid flow and the simultaneous message re harmonic rotational and reciprocating movement, according to the invention re secured in fluid flow console with the possibility of fixed rotation and rotational movement about an axis on which they are fixed, coinciding with the axis of connection of the slide rod and the reciprocating movement of the ER is carried out in the direction perpendicular to n is the Board that flow and coinciding with the vector normal component of the driving force of the flow, the resulting component which is directed perpendicularly to the side surface of the ER, in the best case scenario the implementation of this method, the rotational and reciprocating movement of the manual exercise relative to the axis of the cantilever fixing with a phase shift; this method can be implemented using a device made of single or multi-module, each module which contains the possibility of accommodation in the fluid flow ER mounted on a fixed base on the connecting rod of the crank mechanism, the slider of which is connected to the connecting rod by a pin and is able to perform the reciprocating movement along the guide, and a connecting rod pivotally connected to the crank, hinged associated with the shaft, which, in turn, pivotally connected with a fixed base and is designed to transfer the energy of rotation of the crank on the device for the PTO, which according to the invention, each re is made in the form of the console and installed with the possibility of fixed rotation and rotational movement about an axis on which it is fixed, coinciding with the axis of connection of the slide rod, the best versions of the device when performing his multi-axis pinning ER have the ability to move in one plane; m is Dooley kinematically interconnected and have the opportunity to work with a phase shift; in addition, the kinematic connection between the modules may be implemented via a transfer mechanisms placed on the shaft on one side relative to the stationary base, and it can be fitted with a gland nozzle and diffuser are installed, respectively, in front of ER and ER in the direction of flow.

Due to the implementation of the proposed collection of signs of the use of the claimed device as betroyalcasino electric energy is generated from a stream of water or air with virtually no change in the characteristics of the flow. Given all of the kinetic energy of the flow generated electrical energy is equivalent to approximately 30% of the kinetic energy of the flow (efficiency=30%). The figure shows the results of the tests in air and water flows, the tests were carried out on a laboratory model, and the sample of the pilot plant. When implementing the proposed method of converting the kinetic energy of the flow of fluid into useful work and device for its implementation is guaranteed re moving in the interaction with the fluid flow in the mode of self-oscillation type of flutter. Mode control of these self-oscillations is due to the creation of optimal conditions for stimulating the development and maintenance of a positive work total UAI, that not only reliably protects proposed mechanism from destruction, but this destructive energy into useful work. The energy thus obtained is not due to flutter, and due to the positive work of UAE, which occur simultaneously with the occurrence of self-excited self-oscillation type of flutter. During operation of the device the speed of the working stream at the output of the device is practically no different from the speed of workflow input device that indicates the practical constancy of the kinetic energy of the fluid flow passing through the device regardless of the number and location of the working objects according to length, width and height of the device; increasing the area or number of working bodies increases proportionally removed from the device power (the unit operates in generator mode) or increases traction device (the device is in the mode of propulsion), there is a possibility of infinite increase in output power of any of the fluid flow (including river marine and ocean currents, waterfalls, ebb and flow, etc), also excluded are dynamic blows and jerks at work due to constant the direction of the reciprocating movement of the OM with the normal component of Vigoda flow, this also excludes pressure surges (increasing pressure) at the inlet of the device, which indicates the absence of overturning moment when the device is mounted on roofs, poles, vehicles, decks of ships, etc. that significantly increases the efficiency and reliability of the device. I.e. it is possible to very simple installation and operation of these devices. Conservation of kinetic energy of the flow constant at the inlet and outlet thereof to allow installation and operation of any number and of any power device without disturbing the ecological system in the region, without complex and expensive hydraulic structures. The absence of turbulent flow and laminar flow at the outlet of the device indicates a lack of critical and supercritical speeds on ER, which makes it possible to operate these devices without generating high-frequency noise or interference, no harm to human health, animals and plants. Therefore, there is a possibility of installation of devices in close proximity to electricity consumption, which leads to a substantial reduction in the main (power lines, transformers and substations) and operating (loss of electricity, maintenance of transmission lines and substations) costs. Izgotovleniya and spare parts does not require complicated and expensive materials, the reliability and performance of the main actuators confirmed two centuries of practice of mankind, the devices themselves are reliable and easy to use, and compatible with a simple and reliable control programs, diagnostics and automation. The use of devices as propulsion in vehicles leads to a significant reduction in fuel consumption of marine and river vessels, or an increase in the rate of sea and river vessels at the absolute environmental safety of the aquatic environment. The use of devices as generators of electricity in cars, buses, trams, trains, marine and river vessels also leads to a significant reduction in the consumption of fuel and electricity. The operation of the device eliminates the phenomenon of the greenhouse effects and harmful emissions, eliminates the temperature rise of the planet and related environmental disasters.

A device for converting the kinetic energy of the flow of fluid into useful work (1, 2) contains the console installed re 1, having the opportunity to stay in the flow of fluid 2, it is made in this case of single module, ER 1 fixed cantilever and fixed on the connecting rod 3 mounted on a fixed base 4 of the crank mechanism, the slide 5 which is connected to the rod 3 by means of the axis 6 and has the ability reciprocating movement along the guide 7, and the rod 3 opposite end Sharn the RNC is connected with the crank 8, kinematically associated with the set at the same fixed base one end of the shaft 9, the other end of which is designed to transfer the energy of rotation of the crank 8 in device for a power takeoff (not shown). The amplitude of the reciprocating movement of re 1 depends on the geometrical parameters of the crank 8. Re 1 is installed at an angle of 90° relative to the connecting rod 3 with the angle of attack of L with respect to the flow 2; figure 3 presents the four-module unit with four re 1, installed at an angle of 90° relative to the connecting rod 3 with the angle of attack of L with respect to the flow 2; figure 4 presents four modular device, view from the side gears, made in the form of a gear 10 mounted on the shafts 9.

In addition, ER 1 installed with the possibility of fixed rotation and rotational movement around the axis 6 about which it is fixed to the rod 3, and the geometrical axis axis 6 lies in the plane of re 1. This gives the opportunity set is to pour a fixed phase angle between the rotational and reciprocating movement of re 1, required to run the device and its effective operation, and to stop the device when carrying out maintenance work by setting a zero angle of attack all ER 1 relative flux 2 (mechanism fixed rotation on the figures not shown).

The preferred option the proposed device is when it consists of several of the mentioned modules (3, 4), kinematically interconnected and having the opportunity to work with phase shift. The kinematic connection between the modules may be implemented via a transfer gear 10, mounted on the shaft 9 with the same or opposite directions relative to the stationary base 4. The phase shift between the modules is established via a transfer gear 10.

In yet another embodiment of the proposed device (Fig) it consists of a pair of the number of modules, and the axis 6 of the fastening of re 1 each pair of modules are able reciprocating movement in one plane with a phase shift of 180°.

Figure 5 shows the device for operation in the mode of propulsion of the vessel. The stationary base 4 serves as the ship's hull. The device may be provided with a gland nozzle 11, designed to increase the amount and flow velocity of 2, and the diffuser 12, designed to reduce the pressure of stream 2 re 1, which set the Lena accordingly before re 1 and re 1 in the direction of flow (in the direction of the vessel). Ship engine 13 is a generator, mechanical energy, which re 1 is converted into a thrust force 14.

In yet another embodiment of the proposed device (figure 10) as actuators for the implementation of interconnected harmonic rotational and reciprocating movement of re 1, as well as for fixed rotation re 1 apply kinematically unrelated cylinder 15 performing reciprocating movement relative to the guide 7, and a movable carriage 16 with a hydraulic drive (not shown) of the rotation operation manual 1 carrying out a rotational movement about an axis 6 fastening of re 1. Control of actuators carried out using conventional automation and computer programming.

In yet another embodiment of the proposed device (11) as actuators for the implementation of interconnected harmonic rotational and reciprocating movement of re 1, as well as for fixed rotation re 1 apply kinematically unrelated crank mechanism for reciprocating movement of the ER 1 and a movable carriage 16 with a mechanical actuator in the form of other gear (not shown) rotation re 1, installed on the axis 6 for the implementation of the harmonic rotational motion and fixed rotation operation manual 1.

The method of conversion of the kinetic energy of the flow of fluid into useful work is carried out during operation of the device is as follows. Re 1 is placed in the flow of a fluid medium 2 at an angle L with respect to the flow path 2 with the opportunity to make a reciprocating movement in the direction perpendicular to the direction of flow 2, and rotational movement around the axis 6 about which re 1 mounted on the rod 3, and the geometrical axis axis 6 lies in the plane of re 1 (1, 2). The flow of fluid 2 (6) affects ER 1 in position "A" and creates a force that moves re 1 in the direction perpendicular to the direction of flow 2 (direction indicated by an arrow), and torque re 1 around the axis 6 (Fig 1, 2), the vector normal component of "PN" the driving force of the flow of "P" (6) coincides with the direction of movement re 1, and the resulting "RS" is the driving force of the flow of "P" perpendicular to the side surface of the re 1. The angle "L" between re 1 and the direction of flow decreases, decreases and the magnitude of the impact of stream 2 at re 1. In position "B" re 1 changes the direction of movement on the opposite, when this angle is L=0, the impact of stream 2 re 1 is absent, and the position "B" re runs by inertia due to the energy of rotation of the crank 8 (1, 2). After passage of the "In" (6) the angle of the "L" is different from zero and therefore the force coincides with the inertial force of the crank 8 (1, 2) and moving re 1 in position "C" (6), the angle "L" increases, the vector normal component of "PN" the driving force of the flow of "P" coincides with the direction of movement re 1, and the resulting "RS" is the driving force of the flow of "P" perpendicular to the side surface of the re 1. The maximum exposure of stream 2 ER 1 in position "a" and "C", the angle "L" reaches its maximum and is equal to 45° (in this case). After passage of the "C" corner "L" is reduced, consequently reducing the magnitude of the impact of stream 2 at re 1. In position D ER 1 changes the direction of movement on the opposite, the angle "L"=0, the impact of flow 2 re 1 is absent, and the position "D" ER 1 runs by inertia due to the energy of rotation of the crank 8 (1, 2). After passage of the "D" (6) the angle of the "L" is different from zero and therefore the force coincides with the inertial force of the crank 8 (1, 2) and moving re 1 in position "a" (6), the angle "L" increases, the vector norm is Inoi component "SPM" the driving force of the flow of "P" coincides with the direction of movement re 1, and the resulting "RS" is the driving force of the flow of "P" perpendicular to the side surface of the re 1. The process is repeated.

To reduce the non-uniformity of motion re 1 (1, 2)associated with a change in the movement of the slide 5 with the passage of "dead" pixels (position "b" and "D" 6), and to improve the reliability and efficiency of the device when interacting with the thread 2 on the fixed base 4 (Fig 3, 4) can be placed several (e.g. four) modules. Uniform scheme of the vibrational movement of the manual 1 device provides guaranteed mode self-excited oscillations of the "flutter" when interacting with stream 2, is shown in Fig.7. The arrows indicate the direction of the reciprocating movement of re 1, occurring due to the impact of stream 2 at re 1. The phase angle between the displacement of the neighboring ER 1 set mechanically by appropriate location of the gear pinions 10 (figure 4) depending on the task. In this example, (7) the phase angle between the displacement of the neighboring re 1 is equal to 90°. Work stream 2 (7) interacts with ER 1/1, 1/2, 1/3 and 1/4, four-module unit, the position And the initial moment of time) effect on ER 1/1 maximum (position 1/1(1), angle L=max), the impact on re 1/2 thread 2 does not (the state is 1/2(1), angle L=0), effect of flow on re 1/3 maximum (position 1/3(1), angle L=max, the direction of movement is opposite to the direction of movement of the manual 1/1), impacts on manual 1/4 thread 2 does not (position 1/4(1), angle L=0). During rotation of the crank 8 by 90 degrees (figure 3) RA/1 and 1/3 (Fig.7, the position In the rotation of the crank 8 by 90° relative to the initial time) will take the position 1/1(2) and 1/3(2), respectively, in which there is no interaction with stream 2, as the angles L=0, while re 1/2 and 1/4 will take position 1/2(2) and 1/4(2), respectively, when the influence of flow 2 to this manual will be maximized by maximizing the angle of attack of L. Then the process motion is repeated (Fig.7, the position With the rotation of the crank 8 by 180° relative to the initial time and D is the rotation of the crank 8 270° relative to the initial time) every 90° rotation of the crank 8 (figure 3) on the diagram above. The total force transmitted to the gear pinion 10 (figure 4), will be equal to the total force of the impact of stream 2 all ER 1 device at a time.

To increase the efficiency of energy conversion thread 2 re 1 can be located not only along the stream (figure 3), but in a different way. The scheme of interaction vosmiballnogo device, in which the axis 6 of the fastening of re 1 each pair of modules sovershayutsya-and-forth movement in one plane with a phase shift of 180°, presented at Fig. Work stream 2, acting on ER 1/1 and 1/2 (Posa), moves them towards each other, compressing the volume of flow 2, located in an imaginary camera 1/1-1/1-1/2-1/2. At this time ER 1/3 and 1/4 (potw) are in the neutral position (angle L=0), ready to start the movement (compression stream 2, located in an imaginary camera 1/3-1/3-1/4-1/4); re 1/5 and 1/6 (POSs) move in opposite directions, creating a negative pressure in an imaginary camera 1/5-1/5-1/6-1/6 and contributing to increased energy flow 2, and re 1/7 and 1/8 (.D) are in the neutral position, ready to start moving in opposite directions, thereby creating favorable conditions for further movement of the thread 2. Thus there is an increase in the kinetic energy of the flow path 2 for re 1, therefore, increases and useful operation of the device.

To use the device in the mode of propulsion (figure 5) it is necessary to apply mechanical (electrical) energy from the engine (motor) 13 on the shaft 9, the transmission gear 10 and the crank 8. Rotational movement of the crank 8 through the connecting rod 3 is converted into a harmonic of the rotational and reciprocating movement of the ER 1, which, interacting with the working fluid (liquid or gas), create a thrust force 14 ("Ft"), moving the vehicle (water, land or air) in which UPRAVLENIE, perpendicular to the direction of the reciprocating movement of re 1. The vector normal component of the "Fn" thrust "Ft" opposite to the direction of movement re 1, and the resulting "Fc" thrust "Ft" is directed perpendicular to the side surface of the re 1. The direction of flow 2, resulting from the impact of re 1 on the working fluid (liquid or gas)that is opposite to the direction of thrust vessel 14, and the vector normal component "SPM" the driving force of the flow of "P" coincides with the direction of movement of re 1. To increase the efficiency of conversion of mechanical energy marine engine thrust force Ft of the motion of the ship at the entrance to the device before re 1 it is possible to install the gland nozzle 11, designed to increase volume and flow velocity of 2, and the output of the device for re 1 it is possible to install the diffuser 12, which is intended to reduce the pressure of stream 2 ER 1 (figure 5).

The scheme is the conversion of mechanical energy marine engine 13 in the thrust force Ft (useful work) movement of the vessel (vehicle) on the interaction module device in the mode of propulsion of the vessel with the working environment (liquid or gas) is shown in Fig.9, when the direction of flow 2 is opposite to the direction of thrust 14 of the vessel. The device works in the following way. Re 1 is placed in the working fluid (liquid or gas) at an angle L with respect to the axis of the vessel with the opportunity to make a reciprocating movement in the direction perpendicular to the axis of the vessel, and rotational movement around the axis 6 about which re 1 mounted on the rod 3, and the geometrical axis axis 6 lies in the plane of re 1 (figure 5). The mechanical energy of ship engine 13 through the transmission mechanisms 9, 10, 8 and 3 is converted into a harmonic of the rotational and reciprocating movement of the ER 1, which, interacting with the working fluid (liquid or gas), create a thrust force 14, moving the vehicle (water, land or air) in the direction perpendicular to the reciprocating movement of re 1. Re 1 (Fig.9) affects the working environment (liquid) in position "A" and creates a force that moves the working environment in the direction perpendicular to the direction of translational movement of the axis 6 of the fastening ER 1, around which re 1 commits and rotational movement (Fig 1, 2, 5), the vector normal component of the "RP" driving force "P" of the fluid flow 2 (Fig.9)arising due to the impact of re 1 on the working environment (liquid), coincides with the direction of movement re 1, and the resulting "RS" driving force stream "P" directed perpendicu the RNO side surface re 1. At the same time raises the thrust force Ft, directed oppositely to the direction of traffic flow "R" and moving the vessel along its axis. The vector normal component of traction effort, "Fn" is directed in the direction opposite to the translational movement of the axis 6 of the fastening operation manual 1. The angle "L" between re 1 and the direction of flow 2 is reduced, thus reducing the magnitude of the impact of re 1 on the working environment. In position "B" re 1 changes the direction of movement on the opposite, the angle "L"=0, the impact of re 1 on the working environment is not present and the position "B" re runs by inertia due to the energy of rotation of the crank 8 (1, 2, 5). After the passage of the "b" (figure 9), the angle "L" is different from zero, re 1 is moved to position "C" (figure 9), the angle "L" increases, this increases the impact of re 1 on the working environment, moving it in a direction perpendicular to the direction of translational movement of the axis 6 of the fastening ER 1, around which re 1 commits and rotational movement (Fig 1, 2, 5), vector normal component "SPM" the driving force of the flow of "P" coincides with the direction of movement of re 1 (Fig.9), and the resulting "RS" is the driving force of the flow of "P" perpendicular to the side surface of the re 1. The thrust force of the motion of the ship "Ft" is directed oppositely to the direction of traffic flow "P" and moves UNO along its axis. The maximum impact of re 1 on the working environment at the position "a" and "C", the angle "L" reaches its maximum and is equal to 45° (in this case). After passage of the "C" corner "L" is reduced, consequently reducing the magnitude of the impact of re 1 on the working environment. In position D the operating element 1 changes the direction of movement on the opposite, the angle "L"=0, the impact of re 1 on the working environment is not present and the position "D" of the operating element 1 is held by inertia due to the energy of rotation of the crank 8 (1, 2, 5). After passage of the "D" (Fig.9), the angle "L" is different from zero, the operating element 1 is moved to the position "a", the angle "L" increases, the vector normal component of "PN" the driving force of the flow of "P" coincides with the direction of movement re 1, and the resulting "RS" is the driving force of the flow of "P" perpendicular to the side surface of the re 1. The thrust force Ft vessel moves in the direction opposite to the direction of traffic flow "R" along the axis of the vessel. The vector normal component of traction effort, "Fn" is directed in the direction opposite to the translational movement of the axis 6 of the fastening operation manual 1. The process is repeated.

The phase angle between the rotational and reciprocating movement is set depending on the required task (in the above to skretny schemes the phase angle is 90°). The phase angle between the displacements of neighboring modules is set depending on the required task (in the above specific schemas the phase angle is equal to 90 or 180°). Similarly, depending on the task (the device operates in the generator mode or propulsion), it is possible to adjust the displacement of the center of gravity (center of torsion) ER 1, thereby increasing the torque, and consequently, the force arising from the interaction of the working medium (flow of liquid, gas or mixture) re 1 device and transmitted to the generator (the device operates in generator mode), or from the engine through the device on the working body (the device is in the mode of propulsion).

Scheme of work unit in fan mode is similar to the scheme of the device in the mode of propulsion (Fig.9).
