At one position of the angle, a vertical force arises due to the flow, which moves the wing together with the sliders in one direction; at a different position of the angle, the wing will move in the opposite direction. At one position of the angle, a vertical force arises due to the flow, which moves the wing together with the bearing element in one direction; at a different position of the angle, the wing will move in the opposite direction. Under the influence of hydrodynamic force, the wing 4 together with the supporting element 3 moves progressively in the frame window. The means for changing the position of the wing is made in the form of rotor stops 7 symmetrically mounted on the longitudinal side of the carcass, and the hydraulic force transducer 9 is kinematically connected using the rod 8 to the supporting element 3. In addition, limiters can be made on the supporting element in the upper and lower parts movements 6, with which the angle α is adjusted.

In addition, the mentioned fingers and stops are located at the base of the blades, therefore, when the flow affects the latter, significant torque arises, tending to rotate the blades relative to the stops, which leads to damage to the stops and the blades come off, which also reduces the reliability of the engine. It should also be noted that to reduce the resistance of the flow to the movement of the blades during their idle, the blades rotate and lie on the flexible element, for which they are pivotally mounted on the latter only with their lower edge, and so that they do not move with the flow and do not cling to the flexible element while the working stroke, in the attachment points, fingers and stops are made, which complicates the design, and also reduces the reliability of the engine.
However, this device also has low efficiency, since the force acting on such traction blades is proportional to the relative speed, which is much lower than the flow velocity of the current medium, while the blades are in the working position only on one of the branches of the traction element.
It is known that this force is proportional to the square of the relative speed, which, in contrast to the traction blades, is greater than the speed of the water flow. The specified technical result is achieved by the fact that in the engine for energy recovery of the current medium, containing a longitudinally submerged side transverse to the medium flow, a frame with a window fixed to the foundation, a supporting element mounted in the frame with the ability to move, with an element designed to influence the current medium, fixed in the supporting element the middle part and in working condition is installed at an angle to the direction of flow, as well as means for changing its position, and the device also contains a hydraulic force transducer according to the invention, the carrier element is mounted with the possibility of reciprocating movement in the frame window along its longitudinal sides, and the element designed to act on the current medium is made in the form of a wing with a hydrodynamic profile and mounted on the axis of the carrier element with rotation on the axis and interaction with the flow of the current medium, the means for changing the position of the blade is made in the form of limiters symmetrically mounted on the longitudinal side of the frame Rotating blades and hydraulic force transducer is cinematically connected with the carrier element.

In addition, despite the horizontal arrangement of the blades at idle, the flow of the current medium affects their ends and the back when the blades return to their working position, creating a force that counteracts the working stroke, which further reduces the efficiency of the engine. In addition, the device has a complex mechanical design, since it is necessary to change the position of the blades at idle and on curved sections of the flexible element, which reduces the reliability of the unit. Reliability of the engine is ensured by its simplicity, which also reduces the cost.
Closest to the claimed invention is an engine containing a frame immersed in the current medium with through-holes, installed in the frame from its opposite sides with the possibility of rotation of the shafts, one of which is kinematically connected with the electric generator, a flexible element covering the said shafts and provided with elements – blades, designed to impact on them the current medium, mounted on it with the possibility of rotation, while on the inner longitudinal walls of the frame made guides with grooves, and the blades are equipped with pins with rollers installed in the said grooves, the frame is placed longitudinally across the flow of the current medium, the passage windows are made on the longitudinal walls of the frame, and on curved sections of the movement of the flexible element is installed with the possibility of interaction with the blades means for changing the position of the latter relative to the flexible element on the contrary, the blades on the flexible element are fixed with their middle part and in working condition are installed at an angle to the direction of flow and with the possibility of overlapping the inter-blade gaps of one branch with the blades of the other branch, and at least two pairs of guides are made in the frame, the pins with rollers are fixed on the lateral edges of the blades, and the roller of each pin is each installed in the groove of a separate guide of the corresponding pair (patent RU No.
The angle α is selected from the maximum condition for the power of the device. When reaching the limiter 7 on the supporting frame, the wing changes the angle to the opposite and begins to move in the opposite direction. Having reached the limiter 7, the wing changes the angle to the opposite, after which it begins to move in the opposite direction.
In working condition, the element 4 is installed at an angle α to the direction of flow. Como aliviar el dolor muscular despues de hacer ejercicio . 2πsinγ, where γ is the angle between the chord and the incident flow speed, and the force is directed perpendicular to the free-stream velocity. The wing area can vary due to lengthening of the wing or an increase in the chord. The technical result of the claimed invention is to increase the efficiency of the engine, simplifying its design. The increase in efficiency is ensured through the use of hydrodynamic forces acting on the wing with a hydrodynamic profile. Use may occur at any time of the year. The wing does not require thorough profiling. In some conditions, for example, when moving in circulation, the hull of a conventional vessel can be considered as a wing creating a hydrodynamic lifting force.

If necessary, the wing can perform translational-oscillatory motion horizontally or vertically. In general, the wing performs a translational-oscillatory motion. The wing should be made of light materials or partially hollow to compensate for gravity and hydrostatic force (Archimedes force). Dolor de espalda lado izquierdo . In shipbuilding, wings are used for propeller blades, wing propellers of rudders, hydrofoils, etc. This eliminates the need for the construction of barrier dams and other structures used to accumulate river energy and create a difference and height in traditional devices. To create lift, bodies called wings are used.
