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

The invention relates to a joystick () for controlling an aircraft, including a frame (), a lever () mounted so as to be rotatably movable relative to the frame, and a mechanical linking assembly () for connecting the lever to the frame, the mechanical linking assembly () including: a first linking piece () movably mounted relative to the frame () about a first rotation axis (X), a second linking piece () movably mounted relative to the frame () about a second rotation axis (Y), the second rotation axis forming a non-zero angle with the first rotation axis, a third intermediate piece () mounted so as to the rotatably movable relative to the first linking piece () about a third rotation axis (Y'), a fourth intermediate piece () mounted so as to be rotatably movable relative to the second linking piece () about a fourth rotation axis (X&#x2032;), the fourth rotation axis forming a non-zero angle with the third rotation axis, in which the linking pieces () or the intermediate pieces () are rotatably movable in relation to one another about a fifth rotation axis (Z&#x2032;) forming a non-zero angle with the first rotation axis (X) and the second rotation axis (Y) or with the third rotation axis (Y&#x2032;) and the fourth rotation axis (X&#x2032;), respectively, so as to enable a variation of the angle formed between the first rotation axis and the second rotation axis or of the angle formed between the third rotation axis and the fourth rotation axis, respectively.

Joystick for controlling an aircraft

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.
