Abstract: A damage recovery system of a fuselage of an aircraft, comprising: a tank containing a polyurethane foam; a main duct fluidically coupled to the tank to receive the foam; secondary ducts fluidically coupled to the main duct; and distribution means adapted to allow an outflow of the foam from the secondary ducts. Graphene powder can be mixed and added to the polyurethane foam. In flight, a possible leak (crack or hole) in the fuselage is plugged by the polyurethane foam with graphene powder.
