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. 收起
