Abstract:

An approach power compensator is a device that controls aircraft landing approach airspeed by modulating engine power. Angle of attack, normal acceleration, and elevator position are sensed, and the resulting signals are processed to position an actuator connected to the engine throttle. The device described incorporates a pneumatic piston actuator driven by a fluidic circuit that performs computation, dynamic compensation, and safety override functions. Sensing is done electrically, with the resulting electrical signals converted by electrofluidic transducers. The actuator is powered by a pulse-duration-modulated, supersonic digital fluidic amplifier. Circuits are temperature compensated for stable operation.
