Embodiment Construction

[0024] refer to Figures 1 to 3 , in this example, the flight control device of the invention, generally given the reference number 1 , is mounted on a convertible aircraft.

[0025] The flight control device 1 comprises a base 2 and an operating lever 3 pivotally mounted on the base for pivoting about an axis X of rotation. In this example, a joystick 3 is connected to a control stick 4 of the aircraft for controlling the pitching movement of the aircraft.

[0026] In a known manner, the flight control device 1 has mechanical means for limiting the angular travel of the operating lever about said axis X of rotation. To this end, the operating lever 3 has two abutments 5 a cooperating with two corresponding abutments 5 b of the base 2 to limit the operating lever in a first direction of rotation about the axis X of rotation and in a second direction of rotation angular travel.

[0027] The flight control device 1 also has mechanical means for generating a return force for r...

Abstract

The invention relates to a flight control device (1) for an aircraft, the device comprising a mount (2), a lever (3) pivotally mounted on the mount, and mechanical means for generating a return force for the lever, said means including a spring (6) and a first motor member (13) 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 (18) for assisting said mechanical means for generating a return force.

Description

technical field [0001] The invention relates to a flight control device for an aircraft. More particularly but not exclusively, the invention relates to a flight control device for a convertible aircraft, ie an aircraft capable of vertical take-off and landing. Background technique [0002] The flight controls are used to control the movement of the aircraft based on the movements exerted by the pilot on a control stick connected to the flight controls. Nevertheless, and especially in the case of convertible aircraft, the pilot does not have to fly the aircraft in the same way when the aircraft is in a normal flight phase as when it is in a landing or take-off phase, thereby complicating the piloting task. [0003] In order to assist the pilot, it is therefore known to provide a flight control device comprising: a base; an operating lever pivotally mounted on the base to pivot about at least one axis of rotation and designed to be fixed to the control lever of the aircraft...
