Abstract

A helicopter rotor control mechanism is provided in which cyclic and collive rotor control functions are performed by a single integrated control having three degrees of freedom and operable by either or both hands of the pilot as desired. The integrated control comprises a floor mounted control column rotatable about a fore and aft collective pitch control axis and a pair of hand grips mounted for rotation about two independent cyclic control axes (by one or both hands of the operator) in a control head assembly mounted on the upper end of the floor mounted control column. The floor column and control head effect displacement of collective pitch, cyclic pitch and cyclic roll output rods for ultimate control of the helicopter rotor.
