The invention relates to a force application device for an aircraft control column, the control column comprising a control lever configured to rotate a first shaft and a second shaft, the force application device comprising a first force feedback member configured to exert a resistive force opposing the rotation of the first shaft, a second force feedback member configured to exert a resistive force opposing the rotation of the second shaft and a common braking device comprising a housing, a first braking member and a second braking member which are coaxial and mounted rotatably inside the housing and configured to engage with the first shaft and the second shaft, respectively, so as to brake them, preferably simultaneously.

Force application device for an aircraft control column and method for using such a control column

A movable flight control surface for aircraft, the movable surface comprising: a skin mounted to pivot on a hinge shaft having at least one end that projects from the skin; at least one electric motor that is mounted inside the skin and that has an outlet shaft coupled to the hinge shaft so as to cause the skin to pivot on the shaft; and a power circuit and a control circuit for powering and controlling the motor, the circuits being housed inside the skin and being connected to connectors leading to the outside of the skin.

Movable flight surface having at least one integrated actuator

An actuator for at least one flight control surface of an aircraft. The actuator has at least two actuator members for actuating the flight control surface between two extreme positions and a motor connected to the actuator members by at least one rotary motion transmission line. Each actuator member includes a drive pinion and the actuator is arranged so that the transmission line has an angular amplitude of less than one revolution during movement of the flight control surface between its two positions. The motion transmission line is arranged to allow only one angular position between the drive pinions and the actuator member.
