An installation of systems in aircraft fuselages such as thermophonic insulation mattresses and devices such as onboard systems, and bundles of electric wires or fluid ducts (air, water, oxygen, hydraulic fluid). A structure for fastening onto an aircraft fuselage includes at least frames and stringers, the structure further including: fuselage stabilizers connecting the frames and stringers, wherein two stabilizers of two consecutive frames face each other between the two consecutive frames; and a strip board connecting the two stabilizers and including a fastening mechanism arranged so as to receive corresponding fastening mechanisms of the insulation mattresses and the devices.

Fuselage structure for combined fixing of insulation blankets and items of equipment, aircraft incorporating such a structure

A method for assembling a part of a metal material and a part of a composite material, the junction of the two parts being achieved through a fastener having a substantially constant section and received in a first hole formed in the part of a metal material and a second hole formed in the part of a composite material. According to the disclosed embodiments and before assembling the aforementioned parts, the method includes: an expansion step for generating a field of compression stresses at the periphery of the first hole and locally in the material constituting the part of a metal material using an expansion tool; a single boring step for making the first hole and the second hole with a diameter &#xd8;substantially larger than the diameter of the fastener in order to leave a gap between the inner walls of the holes and the outer surface of the fastener; and an assembling step for placing the fastener inside the holes for maintaining together the metal part and the composite part.
