Abstract
An aircraft wing has a fixed wing portion and a trailing edge flap movable with respect to the fixed wing portion to define a gap between the fixed wing and the flap. A seal assembly has a first rigid seal member fixed to the fixed wing portion and a second resilient seal member fixed to an upper surface leading edge portion of the flap. The trailing edge flap is deployable between a first flap position in which the trailing edge flap conforms to a profile of the fixed wing portion, a second flap position in which the trailing edge flap is deflected upwardly from the first flap position, and a third flap position in which the trailing edge flap is deflected downwardly from the first flap position. In the first flap position the first seal member contacts the second seal member to at least partially seal the gap, and in the second flap position the first seal member presses against the second seal member and deflects the second seal member to at least partially seal the gap.
