The invention relates to the field of alternative energy, in particular to a method of converting kinetic energy of a fluid medium in a reciprocating movement of the wings and the facilities for its implementation and can be used as a source of electrical, thermal and mechanical energy in hydro and wind turbines.

The prior art.

In connection with the environmental degradation of Land and the cost of energy is constantly increasing shortage of energy resources, acquires great importance to the use of such renewable energy sources like natural for lowland rivers, by creating a dam hydropower stations that do not violate their bed.

The rate of flow of the rivers on the plain teaching yet about 1 m/s At such low flow rates using conventional kinetic energy of the flow of water in a mechanical - hydraulic turbines - is ineffective. For example, to produce 1 kW of energy at a flow rate of 1 m/s required turbine with a diameter of not less than 3.5 m, which covers about 10 square meters of the cross-section of the riverbed. Installation is cumbersome and expensive. The reduced dimensions of the turbines is possible at high flow rates, so they found their application in discharge and bag designs.

Widely known systems and other types, for example, axial, rotary and so on, but they also have large dimensions and are very expensive.

The problem of using this renewable energy source, as the free flow of the fluid is to increase the efficiency of the structures which converts the kinetic energy of the flow into other forms of energy.

Long been known, for example, the design of wind turbines with a screw in which to improve their characteristics is applied to the rotation of the blades to control the angle of attack in the process. For example, the design of the wind turbine, created in 1923, Professor, Agricultural Sabinin (from Vita) and implemented in TOCA fluid medium into mechanical with screws, realized values of angles of attack of the blades of these screws is limited by the stall and can't be above critical, therefore, practical application of such devices is limited, and in streams with low speeds their use economically feasible.

A much more efficient design that converts the kinetic energy of the flow into other forms of energy, is the device type "swing wing" (see, for example, U.S. patent N 4470770). This device allows you to realize the benefits of non-stationary mode of the wing flow, and it gives you the ability to use angles of attack greater than critical, and therefore to make greater payload per unit area of the working body (wing).

Known, for example, the apparatus for converting the kinetic energy of the fluid in the reciprocating movement of the wing (see, for example, U.S. patent N 4595336). The apparatus comprises a stationary support on which movably fixed beam. On a beam hinged wings. On the wings by means of hinges installed wing-shaped elements. These wing-shaped elements provided with the actuator to control their angular position relative to the wing. This drive in the extreme on the tion. The beam is connected with the Converter reciprocating movement of the wing into mechanical energy.

In the fluid flow angle of attack of the wing is determined by the magnitude of the angular position of the wing-shaped element relative to the wing. On the wing, streamlined flow of the fluid with the angle of attack, occurs hydrodynamic force. Component of its directed transversely to the longitudinal axis of the beam, creates time, resulting in a beam with pinned her wings receives mechanical movement, doing useful work. About extreme positions of oscillation of the beams of the actuator angular position of the pterygoid element relative to the wing must change the value of this angle on the opposite. Causing the angle of attack should be changed to the opposite, should change the sign of the moment from the hydrodynamic forces of the wing, and the beam must obtain a mechanical displacement in the opposite direction. Thus, according to the author, should be reciprocating movement of the wings.

However, controlled surface in the form of a wing-shaped elements mounted on the wings so that they are a continuation of his profile. Aerohydrodynamics is thew, is very low. Wrap pterygoid elements strongly depends on the angle of attack and there is no possibility to obtain large values. Therefore, the installation may not be effective.

The location of the center of aerodynamic forces behind the axis of the articulated suspension of the wing reduces the total aerodynamic force acting on the wing with wing-shaped element, i.e., reduces the efficiency of the installation.

In the process of turning the beam from one extreme position to another is the change in angular position of the wing-shaped element to zero, i.e. in the process of moving beams there is a change in the angle of attack of the wing to zero, and consequently, decreases the aerodynamic power, beam stop and the change in angular position of the wing-shaped element on the opposite value will not occur. So, not going to happen reciprocating movement of the wing.

Disclosure of the invention

The present invention is to create a way to convert the kinetic energy of the fluid in the reciprocating movement of the wing and installation for its implementation, which would be through the use of optimal law dwane kinetic energy of the fluid into other forms of energy.

This task is solved in that in the method of converting the kinetic energy of a fluid medium in a reciprocating movement of the wings, which consists in the fact that the fluid is placed wing, which is set at an angle of attack to the direction of movement of the fluid flow, resulting in a wing under the action of hydrodynamic forces acting on him, gets a mechanical movement in a direction across the direction of flow of the fluid and to change the direction of movement of the wing mounted the angle of attack is changed to the opposite, according to the invention, when the translational movement of the wings set the angle of attack can withstand constant by changing the angle between the wing chord and the direction of the fluid flow.

This enables to increase the efficiency of conversion of kinetic energy of a fluid medium in a reciprocating movement of the wings.

It is advisable, when reaching the optimal relationship of the speed of the wing and the speed of the fluid flow, the angle between the wing chord and the direction of this thread to withstand constant.

This allows to obtain optimal law is some of the energy of a fluid medium in a reciprocating movement of the wings.

In the extreme positions, before making the return movement of the wing, the speed can be slowed down by turning the kinetic energy of the moving wing in potential, and then with the return movement of potential energy to convert to kinetic, giving him additional acceleration and thus reducing the acceleration of the wing.

This allows to achieve an optimal speed of movement of the wing when using angles of attack above the "critical" and maximize the efficiency of the installation.

This problem is solved in that the apparatus for converting the kinetic energy of the fluid in the reciprocating movement of the wing, comprising a fixed support, movably connected with the beam, on which the hinge is attached, at least one wing, equipped with a device installation angle of attack, made in the form of wing-shaped element, equipped with their own drive to control its angular position relative to the wing, and a beam connected with the Converter reciprocating movement of the wing into mechanical energy, according to the invention the axis of the swivel connecting beam and the wing, is the La fluid medium.

This allows you to get the angles of attack of the wing above the "critical" that provides a significant increase in the efficiency of conversion of kinetic energy of a fluid medium in a reciprocating movement of the wings.

Perhaps the wing to provide a controlled flap, the angle of which relative to the wing in the direction opposite to the deviation angle of the pterygoid element relative to the wing.

This allows to further increase the efficiency of conversion of kinetic energy of the fluid into other forms of energy.

The beam can be connected to the fixed support by means of swivel.

This allows to simplify the installation.

On the fixed bearing, you can hard lock guides, with the possibility of reciprocating movement of the beam installed.

This allows to obtain the optimal trajectory of the wing.

It is advisable, on the fixed bearing in the extreme positions of movement of the beam to install elastic constraints.

Elastic limiting end positions can be set on a beam.

This allows you to reach optimal speeds arrangement of the pterygoid element relative to the wing can be made in the form of a Cam mechanism, containing a Cam mounted on the axis of the swivel connecting the beam with the wing, and the associated thrust with rocker mechanism; a plunger mounted in guides attached to the wing, operatively interacting with the Cam and through a system of levers associated with the pterygoid element.

This allows you to get the necessary angle of attack of the wing during its movement and provides reciprocating movement of the wings.

In addition, the drive to control the angular position of the pterygoid element relative to the wing can be made in the form of a mechanism containing two shoulders lever, mounted on the axis of the swivel connecting the beam with the wing, one shoulder of its associated thrust with rocker mechanism, on the other shoulder it has a finger that interacts with the switch pivotally mounted on the wing, which in turn is connected through a lever system with wing-shaped element.

This simplifies the design of the drive.

You can drive to control the angular position of the pterygoid element relative to the wing to perform in the form of a ratchet mechanism which includes a ratchet wheel, the axis of which is aligned with the axis of the hinge connection of Samadashvili with the ratchet wheel, and through the finger mounted on it, with switch, hinged to the wing and through the system of levers associated with the pterygoid element.

This provides a performance installation at non-uniform fluid flow and strong load fluctuations.

The drive to control the angular position of the pterygoid element relative to the wing may include an inertial mass mounted on a wing-shaped element, and limiting angular position of the wing-shaped element mounted on the wing.

This maximally simplify the design of the drive to control the angular position of the pterygoid element relative to the wing.

The best option of carrying out the invention

The way to convert the kinetic energy of the fluid in the reciprocating movement of the wing consists of the following operations.

In the fluid flow (arrow A), moving with velocity V0placed wing 1 (Fig. 1), which has the ability to move across this thread A.

Near the end position "a" wing 1 is installed at an angle of attack to the direction of flow of A fluid medium, bringing it under the action of hydrodynamic forces R caused it receives mechanical movement in a direction to position "c" across the direction of flow of A fluid medium, doing useful work.

About the other extreme position "c" is the angle between the chord b wing 1 and the direction of movement of the thread A is changed to the opposite, changing the angle of attack to the opposite value is modified as a result of the influence of the hydrodynamic force R on the wing 1, and it performs a return movement to the position "a", also doing useful work.

In the process of increasing the speed of Vymove the wing 1 newly installed angle of attack can withstand constant, by changing the angle between the chord b wing 1 and the direction of flow And fluid.

About the position "a" again the angle between the chord b wing 1 and the direction of movement of the thread A is changed to the opposite, and changes the angle of attack on the original largest value, resulting again changes the influence of the hydrodynamic force R on the wing 1, and it again makes a return movement to the position "c", doing useful work.

Then the cycle is repeated.

About the position "c" the speed of Vymove the wing 1 is reduced, simultaneously, the angle between the chord b wing 1 and the direction of movement of the thread A is changed to the opposite. In the process of decelerating motion Hugo is meniaetsa to zero. Continue to adjust the angle between the chord b wing 1 and the direction of flow A and to change the angle of attack to the opposite value. It changes the influence of the hydrodynamic force R acting on the wing 1, and it performs a return movement in a direction across the direction of flow of A fluid medium to the position "a", doing useful work.

About the position "a" again the velocity Vymove the wing 1 is reduced. Simultaneously, again the angle between the chord b wing 1 and the direction of movement of the thread A is changed to the opposite. In the process of decelerating motion again reduce the angle of attack. By reducing hydrodynamic forces R velocity Vymove the wing 1 is reduced to zero. Continue to adjust the angle between the chord b wing 1 and the direction of flow A and to change the angle of attack to the opposite value. The result is again changed the influence of the hydrodynamic force R acting on the wing 1, and it again makes a return movement in a direction across the direction of flow And the fluid to position "c", doing useful work.

The decrease of velocity Vyperempay attack after some time will have to stall the thread on it hydrodynamic force R will change so that the component of N directed across the flow will decrease, and consequently, will decrease the velocity Vy.

The decrease of velocity Vymove the wing 1 is better performed by turning the work piece hydrodynamic force R acting on the wing 1, the potential energy, reducing or completely disabling the payload. A return movement of the wings 1 this potential energy return to him, telling the wing 1 additional acceleration and thus reducing the time of acceleration.

The velocity Vymove the wing 1 with increasing number of cycles will increase, and when reaching the optimal relationship of velocity Vymove the wing 1 to the velocity V0the flow of A fluid medium, the angle between the chord b wing 1 and a direction of A flow remain constant, maintaining, thus, the optimum largest value of the ratio of the velocity Vymove the wing 1 to the velocity V0the flow of A fluid medium by selecting the geometrical parameters of the wing 1 and the angle of attack for the corresponding load. The result is the most efficient conversion of the kinetic energy t is engaged in the newly developed method of converting kinetic energy of a fluid medium in a reciprocating movement of the wings, contains a fixed support 2, movably associated beam 3, which is hinged at point "O" is assigned to at least one wing 1.

On the wing 1 is controlled flaps 4 and controls the angle of attack of the wing 1, made in the form of wing-shaped element 5 located outside the area of the flow stream of A fluid medium wing 1, which provides a high hydrodynamic characteristics of the wing 1.

Wing-shaped element 5 is equipped with its own drive 6 to control its angular position relative to the wing 1.

The axis "O" swivel is located at a distance of from approximately 0 to 1/3 of the chord b wing 1, which is capable of installing and maintaining the angle of attack of the wing 1, wing-shaped element 5.

The Converter 7 is designed for converting reciprocating movement of the wing 1 in other forms of energy, such as electrical, thermal, mechanical.

On the fixed bearing 2 in the extreme positions of movement of the beam 3 with the elastic stoppers 8, this allows to achieve an optimal velocities of the wing and to maximize the efficiency of the installation.

Although the figures presented one krylovii the transportation works as follows.

In the fluid flow (shown by arrow A, in Fig. 2), moving with velocity V0that will prevent the wing 1 wing-shaped element 5, hinged including "O" on the movable beam 3, associated with the fixed bearing 2. Wing 1 with the movable beam 3 has the ability to move across the flow A.

In the end position "a" wing 1 is installed at an angle of attack to the direction of flow of A fluid medium, by setting the angle drive 6 pterygoid element 5 relative to the wing 1. If the wing 1 is equipped with a controllable flap 4, the last set at an angle relative to the wing 1 in the direction opposite to the mounting angle of the pterygoid element 5 relative to the wing 1. Resulting in wing 1 under the action of hydrodynamic forces R caused it receives mechanical movement in a direction across the direction of flow And the fluid to position "c", doing useful work, which Converter 7 is converted into other forms of energy, such as electrical, thermal, mechanical.

In the process of increasing the speed of Vymove the wing 1 wing-shaped element 5, the angle of flow V is changed, the equilibrium of the system to the verge returns the system wing 1 wing-shaped element 5 in the equilibrium state, turning this wing 1 in the hinge "On", i.e., by changing the angle between the chord b wing 1 and the direction of flow And the fluid and maintaining the thus constant determined angle of attack.

About the other extreme position "c" change the angle of the wing-shaped element 5 relative to the wing 1 to the opposite. If the wing 1 is equipped with a controllable flap 4, the angle of installation relative to the wing 1 is changed to the opposite. The result changes the angle between the chord b wing 1 and the direction of flow A, i.e., the wing 1 is rotated. And opposite to the angle of the pterygoid element 5 relative to the wing 1 set until it reaches the angle between the chord b wing 1 and the direction of flow And zero values, so that in this position it continued to act in the moment of turning the wing 1 in the hinge "On". During this rotation changes the angle of attack on the opposite, changes the influence of the hydrodynamic force R on the wing 1, and it starts the return movement to the position "a" is also doing the job that the Converter 7 is converted into other forms of energy.

In the process of increasing the speed of Vymove the wing 1, Hugo is, the and pterygoid element 5 occurs righting moment, which returns the system wing 1 wing-shaped element 5 in the equilibrium state, turning this wing 1 in the hinge "On", i.e., by changing the angle between the chord b wing 1 and the direction of flow And the fluid, and maintaining the thus constant determined angle of attack.

About the position "a" again to change the angle of the wing-shaped element 5 relative to the wing 1 in the original. If the wing 1 is equipped with a controllable flap 4, and install it again to its original position at an angle relative to the wing 1. As a result of this again changes the angle between the chord b wing 1 and the direction of flow And, i.e., the wing 1 is again rotated in the hinge "O". And again the opposite angle of the pterygoid element 5 relative to the wing 1 set until it reaches the angle between the chord b wing 1 and the direction of flow And its zero value. In the process of turning the wing 1 changes the angle of attack on the initial value, again changes the influence of the hydrodynamic force R on the wing 1, and it starts the return movement to the position "c", again doing useful work.

Th is value "a", or "c" will appear disruption of the flow, the hydrodynamic force R is changed so that the component of N directed" across the stream A, is reduced and decreases the velocity Vymove the wing 1. The angle of incident flow V also changes the equilibrium of the system wing 1 wing-shaped element 5 will be broken, wing-shaped element 5 occurs righting moment, which returns the system wing 1 wing-shaped element 5 in the equilibrium state, turning this wing 1 in the joint "O", i.e., by changing the angle between the chord b wing 1 and the direction of flow of A fluid medium.

Next, change the angle of the wing-shaped element 5 relative to the wing 1 to the opposite value. If the wing 1 is equipped with a controllable flap 4, it is set at an angle relative to the wing 1. The result is again changing the angle between the chord b wing 1 and the direction of flow A, i.e., the wing 1 is rotated in the hinge "O". And again the opposite angle of the pterygoid element 5 relative to the wing 1 set until it reaches the angle between the chord b wing 1 and the direction of flow And zero values, so that in this position it continued to act in the moment, turning the wing 1 in high hydrodynamic force R on the wing 1, and it starts the return movement to the position "c", or "a", respectively, are also doing the work in the Converter 7 is converted into another form of energy.

The decrease of velocity Vymove the wing 1 is better performed by turning the work piece hydrodynamic forces in potential energy, which in the extreme positions "a" and "c" set of elastic constraints 8.

In these terms, it is desirable to reduce, and preferably completely disable payload in the Converter 7. And then, with the return movement of the wings 1 potential energy return, giving the wing 1 additional acceleration and thus reducing the time of acceleration, and then reattach the payload. In this case, the opposite angle of the pterygoid element 5 relative to the wing 1 is not necessary to install until it reaches the angle between the chord b wing 1 and the direction of flow A of its zero value.

The velocity Vymove the wing 1 with increasing number of cycles increases, and when reaching the optimal relationship of velocity Vymove the wing 1 to the velocity V0the flow of A fluid medium, the angle between the chord b is ine the value of the ratio of the velocity Vymove the wing 1 to the velocity V0the flow of A fluid medium.

All of the above follows from the next.

Consider the wing 1 (Fig. 1) placed in the flow of A fluid with density and moving with velocity V0. Wing 1 has the ability to move across this thread A. Let at this time the wing 1 has the angle of attack.

On the wing 1, a streamlined flow of the fluid with the angle of attack, occurs hydrodynamic force Component R. N directed across the flow of A fluid medium, performs useful work on the movement of the wing 1.

Consider the moment when the velocity Vymove the wing 1 is constant.

For steady-state motion with constant velocity Vy= const, V0= const, the power N is doing useful work on the movement of the wing 1 along the axis Oy:

N = Ycos-Qsin (1)

where Y = 0.5 CyV2S, Q = 0.5 CxV2S - hydrodynamic forces;

Cy- the lift coefficient Y wing 1;

Cxthe coefficient Q of the wing 1;

total speed of the wing 1 relative to the fluid;

S is the wing area;

angle of the incoming flow (the angle between the velocity vector V and Victoria Cy/Cx= K - wing as 1, and given that Vx= V0cos() = Vx/V and sin() = Vy/V and introducing the dimensionless quantities

V*= Vy/V0K

< / BR>
get the expression for the power taken from the wing 1 at the steady state movement

W = W*(0.5 CySV3oK2) (5)

In Fig. 3 shows graphs of W*from V*. The maximum value of W*of 0.15 is obtained at V*0,65.

Hence we can conclude: the work of the wing 1 as the engine is more efficient when the speed

Vy= 0,65 V0K (6)

So when K = 10 - 50

Vy= (6,5 - 32,5) V0. (7)

Thus, the optimum velocity Vymove the wing 1, is approximately equal to 6.5 to 32.5 velocity V0the flow of A fluid medium.

When this is optimal angle of attack at which the "quality" K wing 1 has a value near the maximum, i.e., one in which the ratio of the coefficient Cylifting force coefficient Cxresistance is approximately the maximum value:

K = Cy/Cxmaxc. (8)

The actuator 6 (Fig. 2) to control the angular position of the wing-shaped element 5, on animago connection connecting beam 3 with the wing 1. The profile of the Cam 9 is formed of two arcs with a smooth transition from one to another. The Cam 9 is connected by a thrust of 10 with a connecting rod 11, hinged to the beam 3. The slider 12 scenes 11 is connected to the stationary support 2. The Cam 9 engages with the roller 13 of the pusher 14. The plunger 14 moves in the guide 15, is installed on the wing 1. The pressing roller 13 to the fist 9 is, for example, springs (Fig. 4 not shown). The plunger 14 is associated with a wing-shaped element 5, for example, through a system of levers 16.

On the wing 1 may be equipped with a flap 4. In this case, it is also associated with the plunger 14, for example, through a system of levers 17.

During operation when the movement of the wings 1, it is rotated relative to the beams 3 around the axis "O" swivel. The roller 13 rolls on the Cam surface 9. When changing the direction of rotation of the wing 1, the plunger 14, interacting through the roller 13 with the Cam 9, changes its position, i.e., moves from one surface of the arc to the other, and through a system of levers 16 changes the angular position of the wing-shaped element 5 relative to the wing 1 from one extreme position to the other.

If on the wing 1 has a flap 4, and he's from the fixed bearing 2 are determined, so in the end position of the deflection of the beam 3, when the rotation of the wing 1, wing-shaped element 5 has to be moved from one extreme position to the other until the angle between the chord b wing 1 and the direction of flow of A fluid medium reaches the largest angle equal to the angle of attack of the wing 1.

Rod 10 may be connected directly to the stationary support 2 (Fig. 4 not shown). In this case, the distance between the suspension points on the fixed bearing 2 beams 3 and rod 10 is determied by the extreme angle of deflection of the beam 3 from the direction of flow of A fluid medium and the angle of attack of the wing 1, so that the wing-shaped element 5 was moved from one extreme position to the other before the angle between the chord b wing 1 and the direction of flow of A fluid medium reaches the largest angle equal to the angle of attack of the wing 1.

Instead of the Cam 9 with the plunger 14 can be installed two shoulders lever 18 (Fig. 5), attached to the axis "O" swivel connecting beam 3 with the wing 1 and the switch 19, pivotally mounted on the wing 1 including "L". One arm of the lever 18 is connected with a thrust of 10, on the other lever arm 18 has a finger 20 that interacts with the switch 19.

P is, the AK is shown in Fig. 5, because coincide with the geometric axis "O"), and has a lock that eliminates premature actuation of the switch 19, for example, in the form of a surface "M".

The switch 19 is connected with a wing-shaped element 5, for example, through a system of levers 21.

On the wing 1 may be equipped with a flap 4. In this case, it is also associated with the switch 19, for example, through a system of levers 22.

During operation when the movement of the wings 1, it is rotated relative to the beams 3 around the axis "O" swivel. The finger 20 slides on the surface of the "M" switch 19. When changing the direction of rotation of the wing 1, the finger 20 is engaged with the switch 19 and moves it to another extreme position, through a system of levers 21 changes the angular position of the wing-shaped element 5 relative to the wing 1 from one extreme position to the other. If on the wing 1 has a flap 4, and it changes its angular position on the opposite through a system of levers 22.

When the angle of deviation of the beam 3 more than the value of the angle of attack of the wing 1, the finger 20 can be mounted directly on the beam 3, in this case, the rod 10, the connecting rod 11 and the slider 12 is not ustanavlivaut the beam and 3 in the point "O" of its hinged connection with the wing 1 and interacting with the dog 24, pivotally mounted on the wing 1 including "D", through which the finger 25 mounted therein, communicates with the switch 26 set including "E" on the wing 1.

The switch 26 has two extreme positions, limited by stops mounted on the wing (for example, on the axis "D", as shown in Fig. 6, and coincide with the geometric axis "D"). Switch 26 also has a lock, eliminating premature actuation, for example, in the form of a surface "N". In addition, the switch 26 is connected through a system of levers 27 with wing-shaped element 5.

On the wing 1 may also be set by the flap 4. In this case, it is also associated with the switch 26 through a system of levers 28.

Ratchet wheel 23 with the dog 24 can be performed with the gear, a friction roller, etc. links. In Fig. 6 these mesh detail is not shown due to their being well-known.

To avoid jamming of the dogs 24, it can be spring-loaded (Fig. 6 is not shown).

In the process of installing the wing 1 is rotated relative to the beam 3 with the ratchet wheel 23, around the axis "O" swivel. The dog 24 with the slides on the surface of the ratchet wheel 23. When changing napravlennogo position to another and also changes the angular position of the switch 26 relative to the wing 1 from one extreme position to the other and through the system of levers 27 changes the angular position of the wing-shaped element 5. If on the wing 1 is controlled flap 4, and it changes its angular position through the lever system 28.

The actuator 6 (Fig. 2) to control the angular position of the wing-shaped element 5 relative to the wing 1 may be made in the form of the mechanism (Fig. 7) containing the inertia mass in the form of cargo 29, mounted on a wing-shaped element 5. The extreme angular position of the wing-shaped element is limited by the stops 30, mounted on the wing 1.

In the extreme positions of movement of the beam 3 with the elastic stoppers 8, which may be located on the fixed bearing 2 or beam 3.

In the process of installing the wing 1 is rotated relative to the beams 3 around the axis "O" swivel. About extreme position of movement of the wing 1 movement speed it slows down by using elastic stoppers 8, changes the direction of rotation of the wing 1, and under the action of inertial forces acting on the cargo 29, pterygoid element 5 changes its angular position relative to the wing 1 from one extreme position to the other, limited by stops 30.

Industrial applicability

Patent-pending way to convert the kinetic energy of a fluid medium in which the use of such renewable energy sources, what are the wind energy and natural course of the rivers, seas, oceans, etc.

Using the proposed method provides significant savings of energy resources.

Especially important to use plants in lowland rivers with low flow velocity, where without building dams cannot be used in modern turbines.

High efficiency devices using non-stationary mode of the wing flow, allows you to create cost-effective installation at flow rates of 0.2 - 0.5 m/s

Installation can operate under ice.

Install environmentally friendly, because no waste, contaminating the environment. Oscillations of the wing, caused by low-speed flow, have a much lower noise level, which have no impact on flora and fauna.

1. The way to convert the kinematic energy of the fluid in the reciprocating movement of the wing, which consists in the fact that the fluid is placed wing, which is set at an angle of attack to the direction of movement of the fluid flow, resulting in a wing under the action of hydrodynamic forces,Echuca environment, as for changing the direction of movement of the wing mounted the angle of attack is changed to the opposite, characterized in that during forward movement of the wings set the angle of attack can withstand constant by changing the angle between the wing chord and the direction of the fluid flow.

2. The method according to p. 1, characterized in that at achieving the optimum relationship of the speed of the wing and the speed of the fluid flow, the angle between the wing chord and the direction of this thread withstand constant.
