WIND MOTOR Russian patent published in 1994 - IPC

FIELD: aviation engineering. SUBSTANCE: wind motor has stator 1, rotor accommodated in stator 1 and provided wit drive gear 2 and driven gear 3 connected through intermediate link 4 with drive unit of flying vehicle. Rotor 5 has drive shaft 10 with bushing 12 located on shaft disk. Seated in bearings in radial borings of bushing 12 are variable pitch blades 18. Power piston 21 retained against turning by guides 22 is placed in bushing 12. By acting upon piston 21 spring 23 sets blades 18 to maximum angle. Change of blades position to minimum or intermediate angle is executed under action of pressure of oil fed into power cylinder inner space 25 from oil pump. Wind motor is provided with rotary speed governor and reducing valve operating in case of failure of rotary speed governor and limiting racing of wind motor rotor. EFFECT: reduced mass and dimensions and improved aerodynamic characteristics of wind motor. 2 dwg
