Abstract
A spoiler actuation apparatus for moving an aircraft spoiler. The spoiler is moveable between a stowed configuration and a deployed configuration. The spoiler actuation apparatus includes a guide member, a rack mounted on the guide member and slideable along a longitudinal axis of the guide member, and a gear coupled to the rack, the gear arranged to move the spoiler in response to sliding of the rack. The rack is held at a first position when the spoiler is in the stowed configuration. An actuator moves the rack from the first position to a second position along the longitudinal axis. When the rack is at the second position, the rack is operable to accelerate relative to the guide member away from the second position by an aerodynamic force acting on the spoiler.
