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.
Claims5
A fluid turbine having a vertical axis, a rotor and parachute catchers, comprising:
- (a) the vertical axis 1, located in one or several bearing rings 2, and the rotor 3 in the form of a flat horizontal disk, fixed to an upper end of the axis 1;
- (b) one or more pairs of the 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 of the catchers 4 is made of flexible material and in a passive position has a half-chamber shape that has an opening on one side;
- the opening of each of the catchers 4 has a top edge and a side edge;
- (d) an upper edge of the opening of each of the half-chamber shapes is immovably fixed to the rotor 3, and the side edge of the opening of each of the half-chamber shapes is clamped to the rotor 3 by two or more flexible links 5, a first end of each of the flexible links 5 being attached to the side edge of the catcher 4 opening, and a second end of each of the flexible links 5 is attached to the rotor 3;
- (e) the openings of all of the catchers 4 are oriented in a same direction of rotation relative to the axis 1—either clockwise or counterclockwise;
- (f) on an upper side of the rotor 3, above the opening of each of the catchers 4, are located one or more valves 6 with air intakes 7 directed at an angle greater than 45 degrees, relative to a radius of the rotor 3 passing through the valves;
- and
- (g) the valves 6 are in their open position and are directed to an interior of the catchers 4.
