Abstract
A blade system and method of use for a wind turbine to produce electrical power. The system has a vertical rotor shaft coupled to an anchor pad and supports a horizontal blade arm. A blade assembly having a rotatable flap is coupled to the blade arm. The flap captures the wind which causes the rotor shaft to rotate and generates electrical power from an electrical generator.
Claims13
A blade system for use in a wind turbine to produce electrical power comprising:
- a. an anchor pad;
- b. a substantially vertical rotor shaft having a bottom, the bottom rotatably coupled to the anchor pad;
- c. a substantially horizontal blade arm supported by the rotor shaft, the blade arm has a wedge shape cross section;
- and
- d. a blade assembly having a rotatable flap capable of opening and closing to provide an open position and a closed position, the blade assembly has a body having an inner open shape conforming to the wedge shape cross section of the blade arm and the blade assembly body is removably fitted and coupled to the blade arm.

A method for capturing wind forces to rotate a rotor shaft of a wind turbine to produce electrical power comprising:
- a. providing a substantially vertical rotor shaft having a bottom end that is rotatably coupled to an anchor pad;
- b. providing a substantially horizontal blade arm that is joined to the rotor shaft that vertically supports the blade arm, the blade arm has a wedge shape cross section;
- and
- c. providing a blade assembly that has a body having an inner open shape conforming to the wedge shape cross section of the blade arm and the blade assembly body is removably fitted and coupled to the blade arm and has a rotatable flap, the flap having a leading face and an opposite trailing face so that when the flap is in an open position the wind engages the leading face and pushes against the leading face causing the flap to move with the wind and rotate the rotor shaft in a certain direction and as the rotor shaft rotates, the blade arm and blade assembly move to a position where the wind pushes against the trailing face of the flap causing the flap to go to a closed position that reduces drag on the blade arm.
