The described wind turbine has a set of propeller type wind force collecting rotor turbines which is comprised of an up-wind auxiliary rotor blade turbin e, being disposed on the front end of the combined bevel-planet gear assembly, and a down-wind main rotor blade turbine. These rotor blades rotate in opposite directions with respect to one another, and the extender enables th e main turbine to be activated by normal wind speed without any aerodynamic wa ke turbulence effects created by the movement of the auxiliary rotor blade. The super-large scale, integrated, multi-unit rotor blade wind turbine has four sets of wind force collecting rotor blade turbines composed of an auxiliary down-wind rotor turbine and three up-wind rotor turbine units evenly spaced around a central pivotal rotor hub on extenders which are the same length as the radius of the auxiliary turbine blade. The above described wind turbines are provided with a microprocessor pitch control system thereby achieving hi gh efficiency operation and to stall for storm control. |
