ABSTRACT:
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.
