FIELD: transport.
SUBSTANCE: invention relates to aircraft fuselage segment. Fuselage segment comprises inner and outer skins confining center section. Said center section accommodate channel tunnels intended for integration of systems. Center part material hardness increases starting from region of inner skin side toward outer skin. Note here that channel tunnels are mounted at center section in or after its fabrication.
EFFECT: simplified fuselage assembly and segment manufacture, decreased weight, better segment stability and isolation on inner skin side.
