Patent ID: 8162266

Claim:
An assembly for an aircraft, comprising: a flight control surface mounted to a fixed aerofoil structure, a power transfer assembly electrically connecting the flight control surface and the fixed aerofoil structure, wherein the flight control surface is movable translationally relative to the fixed aerofoil structure between a retracted and an extended position, wherein the power transfer assembly comprises a housing, entirety a spool mounted for rotation with respect to the housing and biased to rotate in a first direction, and an electrical cable adapted to be wound around the spool when the spool rotates in the first direction, such that movement of the flight control surface from its retracted to its extended position causes the cable to be unwound from the spool by rotation of the spool in a second direction opposite the first direction, and, wherein the fixed aerofoil structure includes a cut-out in its aerodynamic leading edge through which the cable passes and the cut-out is sealed around the cable by a seal, wherein said seal permits said cable to deflect at said seal upon the deployment of the flight control surface.
