A floor system for a fuselage section of an aircraft is provided. The floor system has an essentially self-supporting design and is substantially mechanically separate from the fuselage section as primary structure. Consequent to the free or self-supporting design of the floor system in the fuselage cell, the layout of the floor system along an aircraft axis can be matched to customer specifications in a simple manner without reference to structural boundary conditions of the fuselage structure. A floor surface for the floor system is formed from a number of floor elements which can be fitted with functional elements, wherein filling of empty spaces or cavities can be achieved with a number of floor equalization elements. As the floor elements have a relatively large support or fixing surface the loads induced by the functional elements are introduced into the floor system distributed over a large area such that the structural components thereof can be of a structurally lighter and thus weight-saving size.
A floor system for a fuselage airframe of an aircraft with a plurality of floor members to form a floor surface, comprising at least two longitudinal supports, which are directly attached to the fuselage airframe in a lower region or in an upper region of the fuselage airframe and on which in each case at least one support member is arranged, wherein the support members can be moved and locked on the longitudinal supports parallel to an x-axis of the aircraft, and in each case at least one crossbar is arranged on the at least two opposing support members for supporting and attaching the floor members, as a result of which the floor system is configured to be substantially self-supporting and mechanically substantially uncoupled from the fuselage airframe as a primary structure.
