COUNTER ROTATING WIND TURBINE GENERATOR IN THE PERIMETER

摘要

The present invention relates to a wind turbine machine comprising a supporting means, a pair of spaced apart counter rotatable front and rear rotors being rotatably supported on said supporting means, said front and rear rotors being adapted to counter rotate correspondingly to a first and second wind loads, a plurality of spaced apart front and rear blades being rotatably secured correspondingly within said front and rear rotors, a generator means being provided between of said front and rear rotors, and a blade pitching means being configured to operate on said front and rear rotors and said blades to control the speed of rotation of said front and rear rotors. The front rotor has a tunneling mechanism directly coupled to the front rotor and a diffuser mechanism for the rear rotor. The blades are made of hollow inflatable materials filled with air with pitching mechanism, making the present invention lighter than the conventional blades design.
