<p>A cargo ramp (12) for an aircraft (10) is constructed of two segments (14, 16) which are hinged together so that they may articulate about the ramp pitch axis. The first of the two segments (14) is hinged to the cargo bed (20) of the aircraft (10) so that it may articulate relative to the cargo bed (20), again in pitch. The second segment (16) abuts a surface to or from which cargo is to be transferred. The hinged ramp permits straight-across loading and unloading of cargo onto vehicles which have cargo bed heights different than the cargo bed height of the aircraft. In a modified embodiment, the ramp also compensates for a differential roll angle between the second ramp segment (16) and the vehicle cargo bed (30). In this embodiment, the hinge connection (118) between the two ramp segments permits relative motion of the second segment with respect to the first segment about its roll axis (136), as well as in pitch.</p> |
