REMOVABLE LIFT ASSEMBLY FOR A ROTORCRAFT, AND A ROTORCRAFT
First Claim
1. A lift assembly for a rotorcraft, the lift assembly being for fastening in removable manner to a fuselage of a rotorcraft and comprising:
- a fixed wing comprising in succession in a transverse direction;
a left lift segment;
a central box for fastening to a fuselage; and
a right lift segment;
the wing having at least two spars extending from the left lift segment to the right lift segment, the wing extending in elevation from a pressure side to a suction side and longitudinally from a leading edge to a trailing edge;
a main gearbox extending in elevation from a bottom towards a top, the main gearbox having a mast for setting in rotation a lift rotor, the main gearbox passing through an opening in the suction side of the central box so that the bottom of the main gearbox is attached to a resilient suspension system arranged at the level of the pressure side of the central box, the top projecting from the central box, the top being fastened to at least one spar by at least three suspension bars; and
a reversible fastener system having a plurality of fastener means for reversibly fastening the central box to a plurality of fastener points of the fuselage.

Abstract
A lift assembly that is releasably fastened to a fuselage of a rotorcraft. The lift assembly comprises a wing comprising at least two spars. A main gearbox passes through an opening in the suction side of a central box of the wing so that its bottom is attached to a resilient suspension system arranged level with the pressure side of the central box, a top of the main gearbox projecting from the central box and being fastened to at least one spar by at least three suspension bars. A reversible fastener system having a plurality of fastener means serves to fasten the central box reversibly to a plurality of fastener points of a fuselage.
