Example 1

[0058] This example of a specific embodiment of the present invention describes a more efficient way of obtaining mechanical work and/or generating power from fluid flows, the operation of which is evident from FIGS. 1 and 2. The method uses the pendular motion of the blade and the counterweight in a direction that is perpendicular to the flow of fluid in conjunction with a smooth and periodic change of the angle of the blade to the flow of fluid over the sine wave. Furthermore, the method performs: [0059] the rotation of the surface of the blade rotation boundaries to the direction of the fluid's flow and/or if a change in the direction of the flow of wind or water occurs; [0060] changes in the amplitude of the oscillation of the blade with respect to the fluid's flow rate and/or if this does not suffice, then also [0061] changes in the amplitude of the angle of the blade with respect to the fluid's flow rate; [0062] capturing mechanical work in the form of torque or tensile/compressive force to propel attached machinery or generate power from the arm of the counterweight.

Example 2

[0063] This example of a specific embodiment of the present invention describes the construction of the apparatus for a more efficient way of generating power from fluid flows, as a modification to a wind turbine mounted below the ground level 26 as shown in FIGS. 1 and 2. The core of the structure is comprised of a pendular arrangement of a vertical blade 1 and a counterweight 5 pivotally mounted onto a pivot joint 3 with the axis 6 of oscillation and installed in static elements 16. In this case, the blade 1 is located above the counterweight 5 and the pivot joint 3 of the blade 1 is located above the center of gravity. The essence of the invention lies in the fact that the pivot joint 3 of the vertical blade 1 with a symmetrical aerodynamic profile and its axis 7 and the arm 2a of the blade 1 is coupled with the counterweight of a slightly higher weight than the blade 1 via the arm 2a of the counterweight 5, while the arm 2a of the counterweight 5 is coupled with the following control mechanisms. The first is the mechanism A with an incorporated flywheel 10 with its axis 17 of rotation, the first articulated mounting 21 with trajectory 18, the first rod 20 and the first pivot joint 22 to capture torque. The electric generator 12 is connected to the flywheel 10. A series of magnets 13 with varying polarities are mounted onto the perimeter of the disc of the electric generator. There are static coils 14 positioned in the magnetic field of these magnets 13. The second is the mechanism B mounted on the shaft 11 with a crank 15 with the contained second articulated mounting 24 with trajectory 19 the second rod 23 the second pivot joint 25 and the lever 4 for the angle of attack for smooth and periodic changes in the alpha angle between 0 and 80 up to 90 of the blade 1 over the entire oscillation from one outermost position 8 to the other outermost position 9 against the direction of the fluid's flow, as shown in the graph in FIG. 1c. The third is the mechanism Q for the smooth rotation of the surface of the blade rotation boundaries to the direction of the fluid's flow containing a length-adjustable member that is placed in the second rod 23. The length-adjustable member is the fourth linear actuator 100, as shown in FIG. 2a and in the graph in FIG. 2b. The fourth is the mechanism D1 for changing the amplitude of the oscillation of the blade 1 with respect to the fluid's flow rate with the first linear actuator 101 attached to the first articulated mounting 21, as shown in FIG. 3a, or with the alternative fifth mechanism D2 for changing the amplitude of the oscillation of the blade 1 with respect to the fluid's flow rate with the second linear actuator 102 attached to the first pivot joint 22, as shown in FIG. 3b. The effects of the fourth and/or the fifth mechanism D1, D2 on changing the amplitude of the oscillation of the blade 1 from the vertical at the beta angle between 0 and 60 up to 90 to the flow rate of the fluid are shown in the graph in FIG. 3c. The sixth is the mechanism E1 for changing the amplitude of the blade's angle with respect to the fluid's flow rate with the third linear actuator 103 attached to the second articulated mounting 24, as shown in FIG. 4a, or with the alternative seventh mechanism E2 for changing the amplitude of the blade's angle with respect to the fluid's flow rate with the fifth linear actuator 104 attached to the lever 4 of the angle of attack, as shown in FIG. 4b. The effects of the sixth and/or the seventh mechanism E1, E2 on changing the amplitude of the blade's angle with respect to the fluid's flow rate are shown in the graph in FIG. 4c.

The difference of the structure lies in the fact that the blade 1 is located below the counterweight 5 and the pivot joint 3 of the blade 1 is located above the center of gravity, while the beta angle of the amplitude of the oscillation of the blade 1 to the vertical is a maximum of 90 of the oscillation.
