Aircraft fuselage and module for absorbing crash energy in a lower deck, used for transporting passengers, of an aircraft

A module for installation into an aircraft fuselage, the module comprising:

• a support device comprising:
• a lower end configured for connection to a fuselage structure in a lower deck of the aircraft fuselage;
• an upper end configured for connection to an intermediate floor in the aircraft fuselage;
• and
• an energy absorption element between the upper end and the lower end;
• a wall panel which is connected to the support device and extends along a longitudinal axis and along a circumferential direction, wherein, as viewed from the longitudinal axis, the support device has a concave form;
• wherein the energy absorption element is configured such that, in an event of a crash of an underside of the aircraft fuselage in which the module is installed, the energy absorption element is configured to undergo a plastic deformation and, in so doing, absorb an amount of kinetic energy of that a part of the fuselage structure connected to the lower end of the support device;
• wherein the plastic deformation and the amount of kinetic energy are of such a magnitude that, in the event of the crash, the module is configured such that the fuselage structure will, at the underside of the aircraft fuselage, deform no more than a minimum height, which is defined as being between a seat surface of passenger seats provided in the lower deck and the intermediate floor.
