Abstract
A vertical axis wind turbine has a stationary circular core and a rotor rotatably supported about the stationary core. The rotor has a radially extending rotor arm with a wind engaging blade locate at its distal end. The blade has at least two straight blade sections of which at least one blade section is inclined obliquely at a first angle.
Claims15
A vertical axis wind turbine comprising:
- a stationary circular core,
- a rotor rotatably supported about the stationary core and having a radially extending rotor arm, and
- a wind engaging blade located at a distal end of the radially extending rotor arm, the blade comprising at least first and second straight blade sections of which at least the first straight blade section is inclined obliquely at a first angle.
A vertical axis wind turbine comprising:
- a stationary circular hollow core,
- a rotor rotatably supported about the stationary core and having a radially extending rotor arm and a wind engaging blade located at a distal end of the radially extending rotor arm,
- an electric generator set located with the stationary core, and
- a torque transmission system for transferring rotational torque of the rotor to the generator set, the torque transmission system including a pair of cooperating gears driving a torque transmission shaft coupled to the generator set, wherein the torque transmission shaft includes an axially movable coupling and a pivoting coupling.
