Abstract
A rotorcraft (1) having a feed unit for feeding fuel to a power plant (13) of the rotorcraft (1). A middle floor (12b) is securely engaged with at least two frames (9a, 9b) of the fuselage, and being load-bearing relative to general forces supported by the fuselage. A bottom compartment (7) of the rotorcraft (1) does not have the load-bearing covering (8) of the fuselage, the bottom face of the fuselage being open to the outside providing the bottom compartment (7) with a bottom (17) open to the outside of the rotorcraft. The bottom face of the middle floor (12b) forms an anchor member for suspending at least one fuel tank (25, 26) that is accessible from outside the fuselage via said open bottom (17).
