PCT No. PCT/KR95/00081 Sec. 371 Date Dec. 17, 1996 Sec. 102(e) Date Dec. 17, 1996 PCT Filed Jun. 23, 1995 PCT Pub. No. WO96/00349 PCT Pub. Date Jan. 4, 1996The described wind turbine has a set of propeller type wind force collecting rotor turbines which is comprised of an up-wind auxiliary rotor blade turbine, being disposed on the front end of the combined bevel-planet gear assembly, and a down-wind main rotor blade turbine together with attached extender having twice the radius of the auxiliary rotor turbine. These rotor blades rotate in opposite directions with respect to one another, and the extender enables the main turbine to be activated by normal wind speed without aerodynamic wake 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 up-wind rotor turbine and three down-wind rotor turbine units evenly spaced around a central pivotal rotor hub on extenders which arc 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 a highly efficient stall and storm control operation. |
