A FLIGHT CONTROL DEVICE FOR AN AIRCRAFT

摘要

The invention relates to a flight control device for an aircraft, the device comprising a mount, a lever pivotally mounted on the mount, and mechanical means for generating a return force for the lever, said means including a spring and a first motor member that are arranged so that a first end of the spring is constrained to move in rotation with the lever and a second end of the spring is constrained to move in rotation with an outlet shaft of the first motor member. According to the invention, the flight control device includes an electrical assistance system for assisting said mechanical means for generating a return force.

1. A flight control device for an aircraft, the device comprising:
a mount; a lever pivotally mounted on the mount to pivot about at least one axis of rotation and designed to be secured to a control stick of the aircraft; and mechanical means for generating a return force for the lever about the axis of rotation, said return means comprising a spring and a first motor member that are arranged in such a manner that a first end of the spring is constrained to move in rotation with the lever and a second end of the spring is constrained to move in rotation with an outlet shaft of the first motor member; the device being characterized in that it includes an electrical assistance system for assisting said mechanical means for generating a return force, the system comprising a second motor member that is distinct from the first motor member and that is arranged in such a manner that its outlet shaft is constrained to move in rotation with the first end of the spring, the system including control means for controlling the second motor member in order to modify the stiffness of the spring in operation by means of the second motor member.
