Water-wind the motor includes a shaft 1, two Il the three blades 2, evenly spaced around the shaft 1 in the same row and made each in two forming a frame of parallel pipes, fixed ends on the shaft 1. Between the pipes fixed terminals 4 with hung on them by the plates 9. On the pipe in front of each terminal 4 and between terminals 4 set the limiters 3 of rotation of the plates 9. The stops 3 are mounted to the frame on only one side, on which hung a pair of plates 9 (6). Limiters 3, located near the terminals 4, made in the form of plates with a slope to the middle of the frame, and stops 3, located between terminals 4, in the form of spheres. Limiters 3 between terminals 4 are set at an equal distance. Limiters are designed to prevent chaotic turns of the plates 9, to hold the plate 9 in the folded position perpendicular to the frame and to facilitate the creation of a ribbed surface uncovered plates 9. Engine components made of steel and plastics. On each rod 4 mounted on the pair of plates 9. The engine is equipped with a massive Playground 6 - place of attachment of the engine, in which a vertically mounted shaft 1, with the possibility of mounting it to the ground, to the platform 7 (figure 1), to transport, to the craft above the surface 8 of the water (figure 2) or stationary. In all cases, the mounting shaft 1 should be perpendicular to the surface of the earth or water. This floor is provision provides water wind turbine under all wind directions and water flows without the aid of the directional system. Platform 7 is designed to install the attachment of water-wind turbine above the water surface and on available seats.
On the shaft of the wheel set 1 5 energy transfer rotation to the mechanisms of the consumers, which may be part of gear or another gear. Plate 9 1/3 width throughout their length are bending 2°, forming the folded plate 9 (figure 4) free running total angle of 4° in each pair of plates 9, which contributes to their instant disclosure when working stroke (figure 5). The motor can be equipped with additional rows of blades 2 mounted on the shaft 1 with offset blades 2 different series to increase the power and improve the compactness of the elements (not shown). The top row of blades 9 is fixed so that any blade 9 of the new series was in the middle between the blades 9 of the bottom row, which has two or three blades. The width of the plates 9 is from 2 to 6 cm depending on the size of the engine.
Water-wind the motor is stationary and transportable. Work of water-wind turbine is based on converting the kinetic energy of the air or water flow into mechanical energy of rotation of the shaft 1, which has 2 or 3 blades, evenly spaced around the circumference of the shaft 1 in the same row or several rows Limiters 3 are divided into two types: located near the rods and located between the rods in the middle. The stops 3 are designed to limit movement of the pair of plates 9, hinged to the rods 4, and retain them in the desired direction during operation of water-wind turbine. Limiters 3, located near the terminals 4, are produced in the form of plates with a slight tilt to the middle of the frame. Plate 9 are designed to take the kinetic energy of the wind/water and transfer it to the rod 4 and misterjaw limiters 3, which in turn transmit this energy frame that converts the kinetic energy of the wind/water energy of rotation of the shaft 1. Plate 9 (2 pieces) are mounted on the rods 4, fixed to the frame with their ends. The edges of the plates 9 in length on 1/3 slightly curved. The bend angle is 2° from the plane of the plates (figure 3). This is necessary as for the free course of the plates 9 (figure 4), and when working stroke of the plate 9 (figure 5). With the free course of the plates 9 are very close to each other, and between them the edges of the plates 9 are two of the limiter 3 (figure 4). Wind or water stream flow round plate 9 evenly over the entire area on one side of the rods 4. In the drawings, the movement of the wind /water/ the arrow. Since the plate 9 are curves 2°, folded plates form an overall angle of 4° in each pair. The presence of an angle 4° between the plates 9 helps with the approach of the frame in the area working position snapshot races is the freight plates 9. When working stroke of the plate 9 is maximally opened in both directions. The angle between them is 90°. Fully open the plate 9 does not give misterjaw limiters 3. Half of those limiters 3 plates stacked with its curved edges. In the second half of limiters 3 lie adjacent plate 9 in the same order, together creating a ribbed surface of all pairs of plates 9. The curvature and the ribbing plates 9 create the resistance of the wind/water, which are indicated in the drawings by arrows. Working position of the plates is depicted in figure 5 and 6 (left). Due to the fact that the shaft 1 is set perpendicular to the surface of the earth or water air /water streams can either side to blow/ wash shaft 1 are installed on the blades 2 and automatically move the plate 9. The area of the uncovered plate 9 of the frame in the working position of the plates 9 is larger than the area of the frame, limiters and folded plates 9 free running. Accordingly, when this occurs the pressure difference of air flow/water on the working blade and the blade is free running, and this pressure difference causes the rotating working the blade 2, which rotates the shaft 1.
With the early departure of the frame with expanded plates 9 from the operating position (left figure 6) due to inertia of motion (at the top of figure 6), the following occurs: a pair of plastic is 9 under the influence of wind /water come together and form a streamlined air /water figures which does not have a significant deceleration frame limiters 3, and the frame has a slight resistance to the oncoming wind/ water flow.
