Abstract

A wind turbine with a vertical axle supporting a plurality of frame assemblies is mounted to the axle in spaced apart radial positions wherein each of the frame assemblies has a vertically oriented flat screen fixed between a pair of spaced apart struts, a stationary or rotating arm is vertically oriented and mounted between the struts and to one side of the screen, and a flexible sheet is fixedly mounted along one of its edges to the stationary arm. With a wind blowing in any direction, at least one of the flexible sheets is positioned for being blown against one of the flat screens, thereby driving the axle in rotation, and at least one of the flexible sheets is positioned for being blown away from one of the flat screens thereby lowering wind resistance.

Claims (24)

1 . A wind turbine comprising:

a vertical axle;

a plurality of frame assemblies mounted to the axle in spaced apart radial positions;

each said frame assembly having:

a vertically oriented flat screen fixed between a pair of spaced apart struts, and

a pivot arm vertically oriented and rotationally mounted between the struts and to one side of the screen;

a flexible sheet fixedly mounted along one edge thereof to the pivot arm;

whereby, with a wind blowing in any direction, at least one of the flexible sheets is positioned for being blown against one of the flat screens, thereby driving the axle rotation, and at least one of the flexible sheets is positioned for being blown away from one of the flat screens.

2 . The wind turbine of claim 1 wherein the pivot arm is secured between a pair of bearings.

3 . The wind turbine of claim 1 wherein the plurality assemblies are between 4 and 8 in number.

4 . The wind turbine of claim 1 wherein the flat screen is of crisscross wire construction.

5 . The wind turbine of claim 1 further comprising a circular support coaxially positioned with the vertical axle and engaged with the struts of the frame assemblies.

6 . A wind turbine comprising:

a vertical axle;

a plurality of frame assemblies mounted to the axle in spaced apart radial positions;

each said frame assembly having:

a vertically oriented flat screen fixed between a pair of spaced apart struts, and

a stationary arm vertically oriented and mounted between the struts and to one side of the screen;

a flexible sheet fixedly mounted along one edge thereof to the stationary arm;

whereby, with a wind blowing in any direction, at least one of the flexible sheets is positioned for being blown against one of the flat screens, thereby driving the axle in rotation, and at least one of the flexible sheets is positioned for being blown away from one of the flat screens.

7 . The wind turbine of claim 1 wherein the pivot arm is secured between a pair of bearings.

8 . The wind turbine of claim 1 wherein the plurality of frame assemblies are between 4 and 8 in number,

9 . The wind turbine of claim 1 wherein the flat screen is of crisscross wire construction,

10 . The wind turbine of claim 1 further comprising a circular support coaxially positioned with the vertical axle and engaged with the struts of the frame assemblies.
