Abstract
An aircraft wing with a wing structure and a spoiler movable between a stowed configuration and a deployed configuration are disclosed. The spoiler includes an actuator configurable between an engaged mode and a disengaged mode. When the actuator is in the engaged mode, the actuator can restrict movement of the spoiler and move the spoiler between the stowed configuration and deployed configuration. In the disengaged mode, the actuator allows free movement of the spoiler, such that the spoiler may pop up due to reduced air pressure on the aircraft wing.
Claims12
An aircraft wing comprising a wing structure and a spoiler movable relative to the wing structure between a stowed configuration and a deployed configuration, wherein the spoiler comprises an actuator configurable between an engaged mode and a disengaged mode, the actuator comprising a cable and a cable drum, the cable being attached at one end to the spoiler and at the other end to the cable drum, wherein in the engaged mode, the cable is arranged to be held under tension and the actuator is arranged to restrict movement of the spoiler and/or move the spoiler between the stowed configuration and deployed configuration, and in the disengaged mode, the tension in the cable is released and the actuator allows free movement of the spoiler such that the spoiler can be moved from the stowed configuration to the deployed configuration unencumbered, and when the spoiler is retracted to the stowed configuration, the cable is tensioned in the engaged mode and arranged to be reeled around the cable drum.
