  • Patent number: 10619740
    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.

  • Patent number: 8220755
    Abstract: A hinge rib for pivotally connecting an aerodynamic control element such as a spoiler or aileron to an aircraft structure. The hinge rib includes a first hinge rib arm having a grain oriented in a first direction and a second hinge rib arm having a grain oriented in a second direction which is not parallel with the first grain direction. The arms may be formed together from a single piece of material, or more typically they are formed separately before being attached together such that the grain of the first arm is not parallel with the grain of the second arm.
