Patent ID: 8672265

Claim:
An aircraft fuselage of an aircraft for freight transport, the aircraft fuselage being traversed by a central wing box, the aircraft fuselage comprising: a floor coupled to the central wing box and adapted to receive and bear a load, the floor presenting an external contour, the floor being subject to elastic movement in response to flexion in the central wing box; and a spacer layer interdependent with the floor, removeable and positioned between the floor and the load, wherein the spacer layer comprises an outer envelope bounding at least one cell, the spacer layer presenting a load engaging surface and a floor engaging surface separated by a thickness of the spacer layer, the spacer layer being in continuous contact with the external contour of the floor over substantially an entire width of the floor, wherein the floor engaging surface of the spacer layer is elastically conformable with the external contour of the floor such that the floor engaging surface is adapted to follow the elastic movement of the floor in response to the flexion in the central wing box, and wherein the load engaging surface of the spacer layer is elastically conformable with the load such that the load engaging surface is adapted to follow elastic movement of the load different from the elastic movement of the floor to maintain uniform distribution of the load on the floor.
