An aircraft part has a fuselage portion and a floor, at least a part of which is joined to the fuselage portion via elastic link rods. Each elastic link rod is provided with a first end that is configured to be fixed to the floor and with a second end that is configured to be fixed to the fuselage portion. The elastic link rods are configured to exhibit a stiffness that makes it possible both to transmit loads between the floor and the fuselage portion and to absorb displacements brought about by deformations of the fuselage portion. The aircraft part thus making it possible, at a lower cost and with a lower mass, to obtain a connection between the floor and the fuselage portion that exhibits suitable elasticity to be able to transmit inertial loads while absorbing deformations of the fuselage portion.

An assembly method includes a succession of assembly steps of assembling fuselage components of the fuselage portion of the aircraft, for example the nose of the aircraft, to form a fuselage body, a mounting step of introducing, into the fuselage body thus formed, a floor module having at least a predetermined width, and which can be provided with items of equipment, and a fastening step of fastening the fuselage body to the floor module such that the floor module shapes the final shape of the fuselage body and the assembled fuselage portion is obtained, the floor module, which has at least a suitable predetermined width, making it possible, when it is incorporated into the fuselage body, to provide the fuselage body, which is slightly flexible, with its desired and definitive shape corresponding to the desired and definitive shape of the assembled fuselage portion.

An aircraft fuselage body is constructed of an upper body section having a curved cross-section configuration and a lower body section having a curved cross-section configuration. The upper body section and the lower body section are joined together to form an aircraft fuselage body by splice straps that are secured, end to end along interior surfaces of the upper body section and the lower body section. The aircraft fuselage body being constructed of an upper body section and a lower body section enables installation of systems separately into the upper body section and the lower body section prior to the upper body section and lower body section being joined together.

A decompression panel assembly for use in an aircraft includes a frame including a first surface and an opposing second surface, wherein the frame defines a grille opening and at least partially defines a flow path opening. The decompression panel assembly also includes a face panel having a first surface retained against the frame second surface such that the face panel at least partially covers the grille opening. A retention mechanism is coupled to the face panel and is configured to retain the face panel against the frame in a closed position.

A decompression panel assembly for use in an aircraft includes a frame including a first surface and an opposing second surface, wherein the frame defines a grille opening and at least partially defines a flow path opening that are each defined between the first and second surfaces. The decompression panel assembly also includes a first panel and a second panel pivotally coupled together at a central hinge. A retention plate is releasably coupled to the first and second panels and is configured to move between a closed position and an open position. The first and second panels at least partially cover the grille opening in a planar position when the retention plate is in the closed position, and the first and second panels move away from the grille opening to a folded position when the retention plate is in the open position.
