Abstract: The invention relates to an actuator (4) for controlling a horizontal stabilizer (3) of an aircraft, including: a primary channel including a screw (6) and a primary nut (7), the primary nut (7) being suitable for engaging with the screw (6), such that a rotation of the screw (6) relative to the primary nut (7) about a rotation axis (X) causes the primary nut (7) to translate relative to the screw (6) along the axis (X), such as to move the horizontal stabilizer (3); a secondary channel including a secondary part (25, 28), and a housing (23, 26), the secondary part (25, 28) being mounted in the housing (23, 26) with play between the secondary part and the housing, in which the secondary channel also includes a play take-up device (27), configured to, in the event of a breakdown of the primary channel causing the secondary part (25, 28) to move relative to the housing, eliminate the play between the secondary part (25, 28) and the housing (23, 26) such as to keep the secondary part (25, 28) in contact with the

Abstract: The invention relates to a joystick (1) for controlling an aircraft, including a frame (2), a lever (3), a mechanical linking assembly (4) for connecting the lever to the frame enabling a rotation of the lever (3) relative to the frame (2) about a first rotation axis (X), in which the mechanical linking assembly (4) includes a first pivot joint (9), the first pivot joint (9) including a first portion, a second portion movably mounted relative to the first portion, and at least two flexible blades, each flexible blade having an end that is attached to the first portion and another end that is attached to the second portion, and being resiliently deformable in order to enable a rotation of the second portion relative to the first portion along the first rotation axis (X) and to generate a return torque which hinders the rotation of the second portion relative to the first portion.

Abstract: A device for generating a return force for a control stick that is movable from a neutral position along a travel path, includes a mechanical connection member connecting the stick to a resilient return member for returning the stick towards the neutral position. The mechanical connection member and the resilient return member produce, over a first portion of the travel path, a first strength of return force and, over a second portion of the travel path, a second strength of return force. A transmission part is mechanically connected to the stick so that any stick movement along the second portion corresponds to turning movement of the transmission part, and so that the return force to the stick is transmitted to the stick positioned in the second portion.
