Abstract
A combined active stick and control boost actuator system for a control surface has a control stick engaged to a mechanical flight control structure with a linkage configured to move a control surface. A mechanical interconnect engages the linkage and has a control stick connection. An integrated actuator is separably connected to the mechanical interconnect intermediate the control stick connection and the linkage. A stick force sensor is configured to provide a stick force signal. A flight control system receives the stick force signal and provides an actuator position control signal to the integrated actuator. The integrated actuator moves to a prescribed position in accordance with a force feel profile providing pilot variable tactile cueing and power boost to reduce both fatigue and workload.
