Title:
A COMPOUND ROTOR SYSTEM OF WIND POWERED ENGINE
Document Type and Number:
WIPO Patent Application WO/2010/025622
Kind Code:
A1
Abstract:
A compound rotor system of wind powered engine has a pilot rotor unit working at low wind speed condition and a main rotor unit working at high wind speed condition. The rotor units are connected to a main shaft through independent clutch devices, so that a controllable rotating detachable transmission relationship is formed between the rotors and the main shaft. By properly switching of the clutch devices, not only a greater starting torque of the wind powered engine is achieved at low wind speed condition, but also the advantage of the main rotor unit at high wind speed condition with excellent wind capturing efficiency is given full play, and the range of speed and region for wind powered engine is enlarged.
