A fuel tank and a differential frame in a fuselage airframe of a helicopter, the fuel tank being installed between the fuselage lower cover shell and the floor panel. The differential frame separates the fuel tank into two individual compartments, the differential frame having a web below the floor panel with a variable-height with a minimum height at the symmetry axis of the fuselage cross-section and a maximum height at lateral frame roots regions. A transversal beam is attached at each of its both ends to the differential frame bridging the entire var...


1. A fuselage airframe of a helicopter comprising a subfloor compartment for a fuel tank, encompassed by a concave cover shell, standard frames and a floor panel covering the subfloor compartment above the concave cover shell, wherein at least one differential frame is mounted to the concave cover shell, the at least one differential frame being perpendicular and symmetric with regard to a longitudinal axis and having an upper section above the floor panel and a lower section below the floor panel and respectively lateral frame root regions merging the u...
