ABSTRACT:
An anti-drive device for restraining against rotation the stationary ring of a rotor control system of a rotary wing aircraft includes a drive tube driveably connected to an engine through a transmission, a rotating ring driveably connected to the drive tube and supported on the stationary ring, pitch links connecting the rotating ring to pitch arms of a rotor that supports rotor blades for rotation and for pivoting motion, and a four bar linkage connecting the stationary ring to the transmission casing. The linkage defines a nearly linear path along which its attachment to the stationary ring travels as the rotor and control system are axially displaced along the rotor shaft and angularly tilted in accordance with the selective actuation of control servos attached to the stationary ring.
