Mini-handle for controlling return force for piloting e.g. pitching, of airplane, has control unit acting on motor as function of measurement signals of position sensor and law of predetermined return force

摘要

The mini-handle has a lever (2) with a degree of freedom in rotation about an axis. A primary cable drum (8) is rotated by the rotation of the lever, and a secondary cable drum (14) is coupled to a stepper motor (20). A cable (12) is connected between the primary cable guide and secondary cable guide. A position sensor (26) provides measurement signals indicative of the position of the lever. A control unit acts on the motor as a function of measurement signals of the position sensor and a law of predetermined return force.
