Abstract: A pylon conversion actuator, for use in tiltrotor aircraft, that converts the tiltrotor between hover flight mode and forward flight mode. Pylon conversion actuator selectively retracts and extends between a retracted position to an extended position. Pylon conversion actuator includes an extendable arm, a motor, and an actuator platform.

Abstract: A wing assembly for an aircraft includes a torque box sleeve having an open end and a plurality of integral sides including leading, aft, top and bottom sides that jointlessly form a continuous surface having a generally airfoil shape. The wing assembly includes an internal support subassembly having a plurality of ribs coupled to a central spar. The internal support subassembly is formed into a single component outside the torque box sleeve and inserted into the open end of the torque box sleeve as the single component. The internal support subassembly is coupled to an interior of the torque box sleeve.

Abstract: One embodiment is an apparatus comprising an aircraft wing; a control surface hingedly connected to a trailing edge of the aircraft wing, wherein a slot is provided between the aircraft wing and the control surface; a seal disposed over the slot, the seal hingedly connected to the aircraft wing; a spring mechanism for preloading the seal against a surface of the control surface such that the gap is sealed with the control surface is in a first position relative to the aircraft wing; and at least one cam blade for lifting the seal from the surface of the control surface as the control surface moves from the first position to a second position relative to the aircraft wing and returning the seal to the surface of the control surface as the control surface moves from the second position to the first position.
