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 variable-height of the differential frame and the fuel tank with two front and rear fuel bladders covering both individual tank compartments with a middle bladder installed between the transversal beam and the variable-height web of the differential frame.
