ABSTRACT:
A rotary wing aircraft has an engine, an engine-driven shaft and a main rotor. A rotor drive shaft is mounted to the main rotor and extends substantially 90 degrees to the engine-driven shaft. A drive pulley is mounted to the engine-driven shaft. A driven pulley is operatively coupled to the rotor drive shaft. A drive belt extends around the drive and driven pulleys. A fluid cylinder has one end stationarily mounted to the engine and another end operatively coupled to the driven pulley to selectively move the driven pulley away from the drive pulley. This movement applies tension in the belt to cause the drive pulley to rotate the main rotor.
