A subfloor structure of an aircraft airframe, particularly of a helicopter, includes longitudinal beams and crossbeams that intersect each other and are interconnected to form a grid that is fixedly attached to the floor and the bottom skin of the aircraft fuselage. Structural elements such as pyramid frustums and reinforcements are arranged on the beams. The longitudinal beam and the crossbeam have a trapezoidal cross-section that is preferably open on the wider base side, closed by a spine web along the narrow side, and bounded laterally by inclined le...


1. An aircraft floor construction comprising a subfloor structure, a fuselage floor supported and secured on a top of said subfloor structure, and a fuselage outer skin secured on a bottom of said subfloor structure,wherein said subfloor structure comprises a plurality of beams including longitudinal beams and crossbeams that are connected to each other, wherein said longitudinal beams intersect and are interconnected with said crossbeams only at respective intersection areas so as to form a grid of said beams with open areas between neighboring ones of ...
