A flight control system utilizing pilot actuated flexible cables to selectively move a control quadrant and utilizing preloaded bungees additionally connecting each cable to the quadrant so that the quadrant can be pilot actuated despite the severance of one of the cables.

Redundant flight control system

A flight control system utilizing pilot actuated flexible cables to selectively move a control quadrant and utilizing balanced, preloaded springs connected to the quadrant to be selectively automatically releasable in response to cable severance so that the quadrant can be pilot actuated through its full control regime despite the severance of one of the cables.

A control for a helicopter having dual, coaxial, counterrotating rigid rotors which varies the cyclic control phase angle of each rotor in flight as a function of vehicle forward speed to thereby control the coupling of lateral cyclic pitch with longitudinal cyclic pitch so as to introduce differential cyclic pitch inputs which automatically produce aerodynamic moments in each rotor to minimize maneuver generated gyroscopic precession moments, which also produce optimum lateral lift vector displacement for all flight speeds.
