Joy stick feel forces, called proprioceptive cues, provide an important sensory feedback to the pilot. Ideally the stick would possess feel forces governed by maneuvers, aerodynamic and structural forces and manual control requirements. Such ideal systems are not normally incorporated in aircraft, since these forces vary continuously and are difficult to produce artificially. This paper discusses a mechanization technique by which such a goal can be achieved. The technique consists of combining an electro-hydraulic position and load closed loop system which can accept any load-position-time command from an electronic function generator. The closed loop dynamic analysis is made and the system is synthesized. Such a feel system is being used in a ground-based motion simulator.
