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.

Abstract: A turret includes a firearm, which is configured to shoot munitions. A support assembly supports the firearm and is configured to move the firearm about an azimuthal rotation or swiveling axis (Y) and about a zenithal rotation or elevation axis (X). A munition guidance device mounts on the support assembly and is configured to direct a precision-guided munition, which is shot by the firearm towards a target. A protection apparatus is mounted on the support assembly and is configured to assume: a covering condition, in which the protection apparatus hides the munition guidance device on the inside of the support assembly; and an opening condition, in which the protection apparatus exposes the munition guidance device on the outside of the support assembly.

Abstract: A firearm support system is adapted to be installed in a vehicle, in particular an aircraft. The vehicle includes a compartment to accommodate the crew. The compartment has: a bearing surface, an upper structure rising above the bearing surface, and an opening, through which a firearm shoots. The support system includes: an anchoring portion, for being fixed to the upper structure and located in the compartment; a mobile support, which is coupled to the anchoring portion in a mobile manner, is adapted for receiving the firearm, and allows the firearm to move between an operating position, in which the firearm is ready to shoot through the opening, and a non-operating position, in which the firearm is retracted.

Abstract: An aircraft is described comprising a transmission unit with a first module and a lubrication system; the first module comprises a casing and a movable member; the lubrication system comprises a header, a nozzle fed with the lubricating fluid and designed to feed the lubricating fluid inside the casing of the first module, a collection tank for the lubricating fluid injected by the nozzle, and recirculation means designed to cause the recirculation of the lubricating fluid from the collection tank to the feed header; the first module comprises a valve available in a first configuration, in which it enables the outflow of said lubricating fluid from said module to the recirculation means when the pressure of the lubricating fluid inside the header is greater than a threshold value; and in a second configuration, in which it fluidically isolates the module from the recirculation means when the pressure of the lubricating fluid inside the header is less than the threshold value.
