A control surface ( ) for an aircraft has a reinforced elastomer surface ( ) on a surface of the aircraft and has a perimeter ( ) attached to the aircraft. An actuation mechanism ( ) moves the reinforced elastomer surface ( ) from a first position, substantially conforming to a moldline of the aircraft, to a second position, protruding from the moldline of the aircraft.

Control surface for an aircraft

A control surface (,) for an aircraft has a reinforced elastomer surface (,) on a surface of the aircraft and has a perimeter (,) attached to the aircraft. An actuation mechanism (,) moves the reinforced elastomer surface (,) from a first position, substantially conforming to a moldline of the aircraft, to a second position, protruding from the moldline of the aircraft.

An expandable fuel cell (72) for an aircraft (70) has a flexible structure (126) having a perimeter (124) attached to an airframe of the aircraft (70). The flexible structure (126) has an empty position, in which the flexible structure (126) approximately conforms to a moldline (76) of the aircraft (70), and a full position, in which the flexible structure (126) forms a smooth curvilinear protrusion from the moldline (76) of the aircraft (70). A fuel bladder (152) is positioned between the flexible structure (126) and the airframe.
