FUEL TANK SUPERCHARGE METHOD Russian patent published in 2018 - IPC B64D37/24 

FIELD: aviation.

SUBSTANCE: invention relates to the field of aviation, in particular to methods for supercharging fuel tanks of aircraft. Method of supercharging fuel tank is to communicate the fuel tank with a source of pressurized gas by means of a supercharging line equipped with a start-up valve and a package of identical throttles installed in series with the gaps, and the activation of the start-up valve. Fuel tank is communicating with the compressed gas source with an additional supercharging line equipped with its own start-up valve and a package of identical chokes installed in series with the gaps. After the pressure in the fuel tank cavity has been reduced to the minimum operating value, a start valve in the additional supercharging line is activated.

EFFECT: reduced level of spreading gas flow of excess pressure, the volume and mass of the gas source of excess pressure or the mass of the fuel tank is ensured.
