Abstract
The device consists of a vertical axis (1), one or more bearing rings (2), rotor (3), one or more pairs of catchers (4) made of light and strong material, flexible connections (5) and valves (6) with air intakes (7). The device can be applied to capture mechanical pressure and extract energy from fluid flows. Since its catchers are made of flexible and light material, it is characterized by a simple structure, light weight, and easy production and repair. Also, the device has a large working area, and reduces to a negligible small value the aerodynamic resistance during the reversible half-turn of the rotor, which further increases its efficiency.
Claims6
1-5. (canceled)
A fluid turbine having a vertical axis, a rotor and parachute catchers, comprising:
- (a) a vertical axis 1, located in one or several bearing rings 2, and a rotor 3 in the form of a flat horizontal disk, fixed to the upper end of the axis 1;
- (b) one or more diametrical pairs of catchers 4 are suspended below the rotor 3, such as the catchers 4 of each pair are centrally symmetrical to each other relative to the axis 1:
- (c) each catcher 4 is made of flexible material and in the passive position has a half-chamber shape that has an opening on one side;
- the opening of each catcher 4 has a top edge and a side edge;
- (d) the upper edge of the opening of each half-chamber is immovably fixed to the rotor 3, and the side edge of the opening of each half-chamber is clamped to the rotor 3 by two or more flexible links 5, the first end of each flexible link 5 being attached to the side edge of the catcher 4 opening, and the second end of each flexible link 5 is attached to the rotor 3;
- (e) the openings of all catchers 4 are oriented in the same direction of rotation relative to the axis 1—either clockwise or counterclockwise;
- (f) on the upper side of the rotor 3, above the opening of each catcher 4, are located one or more valves 6 with air intakes 7 directed at an angle greater than 45 degrees, relative to the radius of the rotor 3 passing through them;
- and
- (g) the valves 6 are in their open position and are directed to the interior of the catchers 4.
