BIFURCATED FEEL SIMULATOR FOR AIRCRAFT.

摘要

A bifurcated feel unit for use in a dual path flight control system includes separate input levers for the pilot and copilot control paths. The input levers pivot about a common axis but are capable of independent rotation upon override of the breakout pogos associated with the control system external to the feel unit. Each input lever is coupled to a source of resistive force, preferably a piston within a hydraulic chamber. Normally the feel force supplied is the sum of the resistive forces applied to each input lever. In the event of a jam in one path of the flight control system, the feel force supplied to the remaining operable path is reduced in proportion to the reduction in available control surface.
