摘要： 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.

摘要： Non-destructive inspection device, comprising: a first structural layer; a second structural layer coupled to the first structural layer; a chamber sealed between the first and second structural layers, containing a gas; and an active region, housed in the chamber, of a Graphene-based material. In a first operating condition, an AC electric current is fed to the active region and generates by thermoacoustic effect a first acoustic wave propagating away from the chamber. In a second operating condition, a second acoustic wave, generated by a reflection of the first acoustic wave, is received at the chamber and causes a variation in pressure and, consequently, a variation in the temperature of the gas contained in the chamber generating, by means of the thermoelectric effect, an electrical signal in the active region.
