BACKGROUND of INVENTION

The present invention relates to improvements in methods and devices disclosed in U.S. patent 4184805 (January 1980), 4347036 (August 1982) and 6273680 (August 2001), issued by Dr. Lee Arnold (Dr. Lee Arnold).

The technical field

The present invention relates to a method and device for use of the kinetic energy contained in a moving flow of the fluid to produce useful power, in particular, to the cascade wings held in a moving fluid environment only console hanging rods. Cascade wings, moving out of phase, can be adapted to extract energy from the fluid to generate electricity using the phenomenon of flutter, requiring two or more degrees of freedom, or by bringing wings in motion from an external source of energy for energy transfer fluid to create traction or discharge using externally programmable fluctuations - also with two or more degrees of freedom.

Description of the prior art

Renewable resources, which in the past were the main sources of energy for human society, include solar energy, wind energy and water, AlN and tides. All renewable resources are derived from solar energy, with the exception of tidal energy, which is the source of the gravitational pull of the moon (geothermal energy, the source of which is the heat accumulated in the earth's crust, is not, strictly speaking, a renewable resource). Active and passive solar energy, wind, water, waves and ocean currents are all connected with the earth's weather cycles, which, in turn, ultimately have their source is solar radiation.

The search for effective means of conversion of renewable energy resources into useful work includes mechanical wind turbines, converting kinetic wind energy into mechanical energy with the use of lifting forces or forces of drag, mechanical and hydraulic turbines, 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.

U.S. patent 1486040 (Schieferstein) discloses a means to create traction with the use of an oscillating wing with a mechanical drive, but having only one degree of freedom is s.

U.S. patent 2783022 (Salzer) describes a device for converting the energy of ocean waves, comprising a series of floats, torque horizontal axis when moving up and down. This device uses an oscillating wings.

U.S. patent 3040976 (de Mattos) discloses a means to create an air traction using grouped in parallel oscillating wings with a mechanical drive, the same - with only one degree of freedom.

U.S. patent 3508840 (Lederlin) discloses a wing or a series of flight feathers of the wings with a curvature designed for recycling soobrazuyas vortices. Such a wing or wings do not work in the flutter or out of phase.

U.S. patent 3783858 (Ashikian) discloses a means of heating the liquid with resonance vibrations in the air column. This invention converts the energy of a fluid medium into mechanical using wings in opposite phase with the flutter.

U.S. patent 3883750 (Uzell) describes placed inside of the cone wind engine type rotating propeller with a horizontal axis.

U.S. patent 3995972 (Nassar) reveals the energy Converter wind oscillating type, in which one or more wings are set in reciprocating motion using a device changing the angle of inclination, which at the end of each turn changes the angle of the wing on Britny. This device uses a flutter with two or more degrees of freedom and described many wings does not work out of phase.

U.S. patent 4024409 (Payne) discloses an oscillating device for converting energy of a fluid medium, which uses the resonant response of the wire, a long cylinder or wing exposed to the oncoming wind so that one surface is generated vortices, creating a force acting on this surface, which is shifted from its position of rest, creating a new vortex on the opposite surface. This new vortex creates oppositely directed force acting on the body, leading to resonant oscillations, which can be extracted energy in the form of a damping force. In this invention, when using its variants in the form of a wing, the wing under the action of the vortex varies with one degree of freedom, and not in a flutter.

U.S. patent 4170738 (Smith) discloses a traction device type (Ponemon) to extract energy from the underwater movement of the water, the transmission of this movement through the reciprocating device rack and pinion on reversing the generator. This device uses the wings, flutter or anti-phase movement.

U.S. patent 4184805 (Arnold) is the first major patent describing antiphase DV is weaker when flutter cascade of wings in the air or water. The invention represents a fundamental improvement in this patent, in which all the mechanisms and thrust attached to each wing, were replaced by a single cantilever suspension rod, mated with the modular power supply system and motion control.

U.S. patent 4347036 (Arnold) is a patent allocated from the same initial application, and describes the same device, and U.S. patent 4184805.

U.S. patent 5457346 (Blumberg) describes a wind engine propeller-type horizontal axis, similar to the U.S. patent 3883750 above, in which the cone concentrates the incident wind on the turbine rotor. This device uses the wings, the phenomenon of flutter or cascade of wing movement in antiphase.

U.S. patent 6273680 (Arnold) continues to develop original mechanical version oscillating cascade power system, as originally disclosed in U.S. patent No. 4184805, with some additional features related to the inertial regulation of the mass and concentration of the input stream using a flat barriers.

A significant part of the literature on aeroelasticity usually considers flutter as in the highest degree destructive force, which, if you allow it to occur in the wing, will inevitably lead to its destruction. The above-mentioned U.S. Pat the options Dr. Arnold show how flutter can in principle be used to extract useful energy from the fluid flow. The present invention is based on the patents of Dr. Arnold and perfects them, creates the possibility of commercial application of oscillating in antiphase cascaded power Converter by eliminating many of the oscillating mechanical parts, linkages, bearings, rods, rods and gears described in these earlier patents.

Although analytical studies of flutter applicable to all fluid media, flutter in the air are well known, but the flutter in the water was not studied or investigated. Patents Dr. Arnold are the first, in which are described the means for initiating and maintaining a flutter in the water.

The INVENTION

The invention discloses the design features durable and effective versions of the Oscillating cascade power system (Oscillating Cascade Power System, OCPS) and requires a set of cantilever wings, which fluctuate and are in a state of flutter due to the kinetic energy extracted from a moving fluid, such as wind, water moving in a stream, river, ocean currents, tides, or in the direction of flow. System power generator includes a new modular unit of Energon is bienia and management, which is driven by the flutter of many wings.

The use of cantilever wings eliminates the need for a significant number of physical mechanisms that are attached to the wings, known from the prior art, described in U.S. patent 4184805, 4347036 and 6273680. The wings are controlled by programmable servo system using the working fluid or electricity. The control program may be executed in the algorithm based on the equations of motion of the wings in the antiphase mode flutter.

Further, the device according to the invention makes efficient use of large quantities of available kinetic energy of the moving fluid flow using a parallel cascade cantilever wings, without the use of bulky attached mechanism. The General term "wing" used here includes the concept of "hydrocrane"used in the flowing water, and aerocrine used to convert wind energy, or "blade"that is used to create traction. The term "wing", implying a fixed or rotary wings used to create a lifting force for aircraft, not applicable in the context of this invention.

One aspect of the invention is to provide in a cascade of wings in disuses the flow of fluid, operating out of phase, independent of the modular apparatus of the wing, power and control, so that the individual wings can be inserted or removed from the cascade, even during operation of the cascade, without touching or affecting the operation of the adjacent wings.

For occurrence in the wings flutter, i.e. resonant oscillations with two or more degrees of freedom, the effective inertial mass of the wings and the presence of a restoring force at the end of the stroke are critical. Aspect of the invention is the creation of new funds instant regulation and control of inertial mass and the restoring force during operation of the system, enabling us to provide continuous and automated operation of the system with variable characteristics of the flow and load.

In the resting position the wings have zero angle of attack. Oscillations do not occur, even if the wings are immersed in a moving fluid flow. In the prior art it was necessary to cause physical perturbation of the wings to start the engine and create a flutter. Another aspect of the invention are remote create vibrations without manual intervention. Moreover, the prior art has not provided any means to stop the oscillation of the wings, in addition to stopping the flow of a fluid is Reda, or cope with fluctuations due to the damping mechanism for the application of limit load. According to the claimed invention means an instant stop one or all of oscillating wings by bringing them to a zero angle of attack and thus the cessation of energy production while maintaining the flow of fluid and without excessive stress or damage to the wings or related mechanism.

Another aspect of the invention is to provide a supporting structure of dual purpose, on which are fixed a number of independent modules wings and which also carries the collectors of the power supply and control systems used to connect modules of the wings to the Central controller. Collectors come with a number of multi-channel shut-off valves and connectors, so that you can easily enable or disable multi-channel connectors of the individual modules of the wings.

Another aspect of the invention is the electronic control of all internal and external parameters of the system, including the speed of the fluid and the load, by processing the data in the programmable logic control device having a special control algorithm, and provide a continuous regulation of the inertial mass and the restoring forces not only optimizes the working characteristics the specifications specifications system at any point in time, but also extends the operating range of the system by reducing the critical velocity of the fluid to initiate flutter and increase the maximum speed or trip speed at which safe operation of the system. In the prior art such improvements cannot be achieved, because the oscillating cascade and its control system are entirely mechanical in nature and must first be disabled for carrying out any adjustment of the inertial mass or restoring force.

The aspect of the invention relating to the creation mode traction or discharge cascade wings, is possible, thanks independently and externally managed modules wings provide many different ways programmable sequential or simultaneous movements of the individual wings with two degrees of freedom to optimize traction or discharge. For example, the cascade can be programmed to reproduce a consistent swimming motion in the cascade that would have been impossible in the prior art.

Another aspect of the invention relating to the tractive effort is that a separate wing can be programmed separately in create mode traction or discharge, and if it cryoablate element cascade, other elements of the cascade can be installed in a transverse position to block the other threads of the fluid to facilitate the management of a river or stream.

Thus, in General terms describes important features of the invention and its significant differences from the prior art, including, in particular, three patents, Dr. Lee Arnold, for a better understanding of the following detailed description and to better understand the new contribution to modern art. Additional features of the invention that will be described below, is included in the formula of the present invention. Specialists in this field will be clear that the claimed invention can be used as a basis for designing other funds for other purposes of the invention. It is therefore important that the formula of the present invention was examined with regard to equivalent structures and methods within the General scope of the invention.

DESCRIPTION of the PREFERRED versions

Figure 1 shows four vertical wing 1, each of which is suspended on, and only on, the hanging rod 2 round cross-section. The rods 2 are from the bottom of a number of independent but identical units stationary units power module/control module 3. Any even number of power modules/control modules 3 mounted on a rigid support structure system 4. The weight of each of the wing 1 is retained his power module/control module 3. Each power module/control module 3 consists of a power module 3A and the control module 3V. Suspended rods 2 are held rigidly upright and parallel by passing through two vertical coaxial bearing installed on the power modules 3A and/or the control modules 3V. The wings 1 can be completely submerged and not have mechanical joints with nothing but the suspension rods 2. The rods 2 have the freedom of translational movement (side by side) in a limited scope and freedom of rotation around the vertical axis, also to a limited extent, but are kept from moving in the flow direction (forward-backward) or rotation (swinging) in the longitudinal direction. Accordingly, the wings 1 are all console so that they remained rigidly in a vertical position at any point in time, but were capable of rotational and translational movement for a limited distance. In particular, the wings 1 can not be moved (or swing) in the direction of flow under the influence of the attractive force of the fluid.

Interval translational and vertical rotational motion of the wing, allowable when such a design is decomposed into any position or combination of angle and offset of the wing needed to initiate and maintain flat the RA in the cascade. Adjacent wings 1 are limited to the management modules 3V exact antiphase movement, as at lateral and rotational movement (tilt), to perform the necessary conditions for flutter in the cascade. The output power from each of the wing 1 is transmitted via the respective power module 3A, acting only on the lateral movement of the wing on the site of the stroke of the wave movement schedule of the wing. Communication with the power module/control module 3 is carried out by feeding the fluid under pressure (hydraulic or pneumatic) or by electrical means. Designed a distinctive feature of the units of the power module/control module is that one unit may be removed from the working generation system, and replaced without stopping or any other effect on the operation of the remaining units.

As shown in figure 2, the control module 3B provides a means for simultaneous induction of lateral movement (displacement) and independent of the rotational motion of each of the wing 1. Analytically, this combination of independent angular movement and movement along the Z axis can be decomposed into any possible movement of the wing or provisions necessary for the initiation or maintenance of flutter, in particular, (a) the independent synchronization to lebani front and rear edges, and (b) applying an external differential restoring forces and the inertial masses of the front and rear edges, necessary to initiate and maintain a flutter. Additionally, in combination with the attached power module 3A, this mechanical design provides (C) the rigidity of the cascade wings in the direction of flow, on the X-axis (limit slipping) and (d) strict parallelism of all the suspension rods 2 in all operating conditions. Finally, each unit control module/power module 3 provides vertical support wings 1 without any interaction with any of the working axes of the cascade - translational or rotational. The upper end of the support rod wing 2 passes through both of the module power supply and control systems and has slots in the passage through the control module 3V to ensure the transmission of the rotational force (torque). Vertical suspension rod 2 can be mounted in two bearings, one of which is located in the upper part, and the second is at the bottom of the unit control module 3B, at least one of which is a thrust bearing. Accordingly, although the control module 3V remains stationary, each suspension rod wing 2 can be independently rotated on a vertical axis within a module, to the extent limited radial space in the camera rotation 6.

Rotation. In the control module 3V litovany suspension rod wing 2 passes through the ACC is respectively litovany rotary impeller 5. The impeller 5 can rotate around a vertical axis inside the rotary chamber 6, is placed in the piston translational motion 7V. The rotation of the impeller 5 is limited to structural range of about 40 degrees to the radial shape of the chamber 6. The Central surface of the impeller 5 is kept from contact with the wall of the internal chamber through a small gap and sealed vertically by means of internal and external seals type "piston ring 8 and 9. The upper and lower ends of the impeller 5 has a similar seal (not shown in Central cross-section), so that in the inner part of the segments of the camera can be created pressure fluid. Channels for supplying a fluid medium 10 and 11 pass between the chambers of rotation 6 and the longitudinal peripheral grooves 12 and 13 respectively in the piston translational motion 7V, leaving in the outer holes 14 and 15 leading from the control module 3V. Thus, the pressure of the fluid applied to the hole 14, leads to the corresponding negative (counterclockwise) rotation of the rotary impeller 5. Similarly, the pressure of the fluid applied to the hole 15, results in rotation of the impeller 5 in the positive direction. Piston rings 16 on both ends of the piston translational motion 7V ensure that giving is the giving of a fluid medium, attached to the holes 14 and 15, which effectively caused the rotation of the impeller 5 inside the piston 7B, while the piston 7B is independent of the translational motion within the prescribed limits of its longitudinal movement. In General, regardless of the position or movement of the piston 7B, the rotary impeller 5 will transmit precisely controlled torque (rotational motion) to terminal 2 and the wing 1 in the application from the outside pressure of the fluid without any moving parts, hoses or moving connections.

The offset. The piston translational motion 7B can move in the longitudinal direction inside the cylinder 17B with a small gap without actual contact with the cylinder wall, but at the same time to seal the piston rings 16, which also seal the fluid acting on the rotary impeller 5. Both ends of the piston 7B are, in fact, all the supporting rods of the piston 18V installed in the guide roller 19, a typical transfer with circulating balls mounted on each end of the cylinder 17B. The lengths of these supporting rods of the piston 18B and the depth of the corresponding holes in the ends of the cylinder are determined by the presumed translational movement of the piston 7B. Additional axial seal type piston rings 20 provide that the pressure of the fluid attached to the holes 21 or 22 in the cylinder 17B, effectively cause a longitudinal movement of the piston 7B in any direction without the need for any moving parts, hoses or moving connections with collectors.

In General, using the above tools and regardless of the instantaneous translational and rotational positions of all wings 1 in the cascade can be synchronized in exact anti-phase movement.

The parallelism of the wings. Obviously, due to the fact that the suspension rod wing 2 passes through both of the piston of the control module and power module 7B and 7A, but is held from any movement except rotation, upper and lower bearings, and due to the two horizontal components of the supporting rods of the piston 18B and 18A, moving in the guide roller 19C and 19A withheld from any angular motion along the Z axis (horizontal swing), all wings 1 that is attached to the suspension rods 2, must remain parallel at any time and in any conditions lateral and rotational motion.

The restriction lug. Similarly, in the plane of the flow outboard wing rods 2 are held from any movement along the X axis (i.e. swinging in the direction of flow under the influence of enthralling force of flowing water or air acting on the wing 1, the vector si is s which varies with the instantaneous angle of the wing) by means of rods 2, passing through the upper piston 7 Into and through the lower piston 7A, which are restricted to the lateral reciprocating motion.

Centering and supporting invigorating. Modules power supply and control systems 3A and 3B include internal springs 18A and 18B to create, partially or completely, cyclic restoring forces necessary to maintain flutter, and to ensure constant alignment of the pistons 7A and 7B, in their respective cylinders 17A or 17B at rest. It should be understood that instead of springs 18A and 18B can be used by means of absorption/impact pneumatic or hydraulic energy.

Figure 3 is a top view of the Central cross-section of the power module 3A. Forward movement of the piston 7A is identical to the movement of the piston 7B control module 3V in any case, when freely in two directions, the piston 7A and 7 In moving forward, guided in its lateral movement of the respective two support rods of the piston 18A and 18B, moving on rails bearings 19A and 19B except that instead of passing through the Central rotational impeller and cylinder suspension rod wing 2 passes only through a sealed single-row or double-row ball bearing 23, vstavlenna is in the center of the piston 7A. Thus, a suspension rod wing 2 can freely rotate around a vertical axis in a power module 3A, but any progressive movement is suspended from the wing 1 and the hanging rod 2 causes a corresponding lateral movement of the piston 7A. Such lateral movement of the piston causes corresponding ejection or retraction of the working fluid through the outer holes 21 and 22. Any number of independent modules hydracrylic can be connected to the six common collectors of the power transmission fluid 24, 25, 26, 27, 28 and 29 along the cascade ends at the controller, as shown in Figure 5.

Figure 4 is a schematic diagram of the hydraulic connections of the cascade of any even number of power modules/control modules 3 with six obshcheshkolnye collectors of the power supply and control systems. Figure 4 shows only three consecutive and adjacent module of the wings, which are enough to illustrate the corresponding interconnect any number of wings. Because the outer holes on each module of the wing completely stationary at any point in time, all the collectors and the interconnections made with conventional piping, couplings and connectors constant pressure. The outside hole of the rotational elements of each control module 14 and 15 connected to the "+"-bramat is linoma manifold control 24 and to the "-"rotary manifold control 25 thus, what sign interconnected pairs of control modules alternates between successively adjacent modules wings. Thus, the holes 14 of the wings a and C connected to the collector 24 and the hole 15 of the module, etc. for all of the wings in the cascade. Accordingly, the holes 15 of the modules a and C are connected with the manifold 25, and the hole 14 of the module Century These two collector rotation control 24 and 25 are effectively connected together at their end of the hydraulic tank pressure, depicted in the controller figure 5. As a consequence, the alternating interconnects rotational elements adjacent control modules wings provide synchronization of all rotational movements of the adjacent wings 1 exactly in antiphase, as if with mechanical linkage.

Accordingly, the holes 21 and 22 of all wings alternately connected to the collectors of the control of translational motion along the Z axis 26 and 27, so named because the lateral movement of the wings 1 occurs along the Z-axis, while the fluid medium (air or water)flowing in the cascade, is defined as moving in the direction of +X. the lateral movement of the adjacent wings, in the same way as described above for the rotational movements that are synchronized among themselves in the exact opposite. Finally, the combined effect of the above-described control systems rotational and ongoing the first movement is any move of all wings 1 in the cascade is exactly out of phase at any point in time, as required by the results of Dr. Arnold analysis of flutter, and at the same time, all the wings Assembly 1 have the freedom rotational and lateral movement, synchronized in antiphase, but otherwise in no way limited. The resultant of any combination of the above-described rotational and lateral movement of hydrocoil, with proper control, can thus reproduce any movement or position required by results of the analysis of flutter for Arnold, as if the wings 1 were associated connecting the upper and lower parts of the front and rear edges of the mechanical rods, interconnected levers and rods, as described in patents issued to Dr. Arnold. The difference is that each wing 1 is now physically independent from all other wings without any mechanical devices or connections between the ends of adjacent wings.

Figure 5 is a schematic diagram of elements of the same type of system Central hydraulic power supply and control systems for cascade.

Synchronization is out of phase. The system controller is depicted here as two hydraulic reservoir under pressure 28 and 29, containing pistons dvuhstoronnej the steps, the Central position of which correspond to the resting position of the wings 1 (the wings are the same distance from each other and parallel to the direction of flow). The same control functions can also be obtained directly by using a programmable microprocessor controller set dual proportinally valves connecting each collector in proportion with the reservoir of fluid under pressure or with the return reservoir fluid. The linear position sensor/speed 30 on each piston rod shall submit to the controller, the feedback signals of the translational and rotational position and movement of the wing. A more complete feedback system to determine the position and movement includes sensors placed on each module of the wing, providing a detailed error information for each wing.

Healing power. To maintain a flutter in the fluid flow necessary to provide restoring forces when approaching the wing, and in the provisions of the extreme bias of the wing, and the exact value of the force varies over the business cycle. Module restoring force 41 provides the necessary at the end of the cycle recuperative using one or a combination of internal springs, controlled compressible volume of who's who of the ear or electrical simulation of the elastic force. Additionally, partial restoring force provided by the springs 18C plus the compression of air supporting the piston rods 18A and 18B.

The inertial mass. In addition to the above-described periodic restoring forces to maintain flutter also need to provide the exact amount of the additional inertial mass to the oscillating mass of the wings. Module inertial mass 42 (Figure 5) applies controlled additional weight to the wings 1 by connecting the working fluid, the control value added inertial mass using proportional control of the working fluid (hydraulic lever), paired with physical mass, or by electrical simulation identical forces.

Run. Multipurpose adjustable control valve with electric actuator 31, which is connected with a hydraulic high-pressure accumulator 32 (Figure 5) and with hydraulic return manifold, which allows the application from the outside (from the collection tank capacity fluid) pre-programmed initial pulse rotation and offset to the wings 1 for excitation of oscillations in the flow of air or water.

Control and optimization of flutter. The application of differential restoring forces and additional inertial masses to re the it and the rear edges of the wings 1 is critical for excitation, and to maintain flutter. Feedback data about the rotational and lateral position of the wing, frequency, instantaneous flow of water or air speed and external load, and other information are input signals to a programmable logic controller, which, in accordance with pre-programmed working algorithm, controls instant addition of the necessary restoring forces and the inertial mass to the wings 1.

It should be noted that flutter after excitation is a self-sustaining phenomenon of resonance, while ensuring all relevant conditions input power (the flow of water or air), output load (damping) and differential restoring forces and masses. This control adjusts continuously and instantaneously produced by the control system to compensate for changes of the above working conditions.

Stop. By external programming forced return to the resting position of the wing the whole cascade or a separate wing can be instantly switched off in case of emergency or for maintenance. By installing a multi-channel valve interconnects the collector-wing individual modules of the wings can be detached and replaced without stop the cascade as a whole.

Maintaining the operating pressure of the fluid. The control system includes a means of maintaining pressure in the secondary circuit of the working fluid, but they are not shown on the drawings and not described, as they are the standard design of hydraulic technology.

6 is a schematic diagram of a typical means of selection of electrical power output related to household energy, describing one of a number of alternative means of supplying power from the cascade to the external load.

Working fluid from the power reservoir 43 is stored under pressure in the accumulator 32 for subsequent actuation of the jet engine 33, which actuates a conventional synchronous alternating current generator 34 to supply synchronized in frequency and phase of the electric power in the household grid. In this illustration, the working fluid is periodically displaced under the pressure of the power modules 3A in a controlled flutter and incoming power manifolds 39 and 40, flows through odnopetlevye valves in the tank 43. Rotary hydraulic motor 33, in turn, is actuated by hydraulic pressure, taken from the battery 32 through controlled proportional flow valve 37.

The hydraulic motor 33 leads directly to action the e conventional three-phase synchronous alternator 34, which is connected through the respective solid-state switch 38 and suitable electrical fuse with household grid. Circuit switching equipment output power is controlled by synchroscope 35 so that the fully synchronized alternating current generator 34 is connected to the network as the alternator 34 and the chain passed through the point of zero voltage. A flow valve is controlled by the frequency and output current of the alternator in order after the establishment of synchronization maximum output power defined by the characteristics of the flow of water or air, power generator and the temperature.

7 is an axonometric view of a single module of the wing, showing details of the construction of the wing is designed to reduce the vortex: (a) the rounding at the end of the wing leading edge 61 shown in Fig.7 and 7A, (b) adding flaps 63 on the end of the rear edge of the wing 65, (C) the inclusion of a deformable flexible departments 67 shown in Figv and 7C along the front and rear edges, and the degree of deformation is determined by the instantaneous angle (via the Central controller). Longitudinal deformation of the flexible division 67 is called the hydraulic pressure acting through the hanging rod of the wing 2. Sent in one the C two cavities corresponding form within the Department 67 hydraulic pressure forces the tail part of the Department to bend in the longitudinal direction from the Central position of rest respectively left or right on respect to the flow axis. Accordingly, when large angles of inclination of the edge of the wing 1 is not already forms an acute angle (prior art), which causes considerable turbulence flowing. Only Department 67 rear edges depicted in FIGU and 7C, but deformable Department can likewise be used on the wing leading edge 1.

Thin, flat and smooth flaps 63, one at each end of the wing 1, and rounded corners, as shown, also serves to minimize vortex formation and thereby reduce the effective drag and increase efficiency. The exact shape design flap 63 is determined by the aerodynamic analysis of the specific geometry of the wing.

Fig is an axonometric view of the complete Assembly oscillating cascade, indicated in General position 68, provided with an inlet pipe 70 and the exhaust manifold 72, designed to change the speed and pressure of the fluid to increase the overall efficiency of power transmission. Features of the species in the plan and in the context of pipelines can vary depending on the aerodynamic analysis of the specific characteristics and geometry of the cascade, which should be placed at the junction 74 between the inlet and outlet piping.
