ABSTRACT:
A floor construction for the upper compartment of an aircraft having an about circular fuselage cross-section. A one piece floor plate provides bending supports and extends over nearly the full inner diameter of the fuselage. A connection is provided between the edge of the floor plate and the fuselage outer structure for transmitting forces directed predominantly in the longitudinal direction of the aircraft. Vertically running planar structural members provide side support elements for the floor plate. The construction results in a decrease of the construction weight as well as of the costs, in particular if the floor plates are provided from fiber reinforced plastic. The connection between the floor plates and the fuselage frame can be provided by rods running at an angle forwardly, which transmit preferably forces acting in the longitudinal direction of the aircraft.
