ABSTRACT:
A removable aircraft floor structure-reinforcing strongback is removably attachable to seat tracks in a conventional civilian cargo aircraft to increase the floor structure load rating thereof. The strongback does not require any permanent modifications to the aircraft fuselage and preferably engages seat tracks in the aircraft floor structure.
The strongback comprises a removable beam extending longitudinally over a significant distance of the aircraft center line. The strongback re-distributes local loads from one section of the aircraft floor structure to a plurality of transverse floor beams underneath the strongback. In this manner, the axle load rating of the aircraft floor is increased for supporting military vehicles.
