FIELD: fuel systems of aircrafts, mainly unmanned ones.
SUBSTANCE: system for pressure charging a fuel tank has fuel tank (5), fuel cavity of which is connected to line (6) for feeding fuel into engine, and gas tank (1) with charging valve (2), connected through launch valve (3) and pressure regulator (4) to the tank. Solid-fuel gas generator (7) is connected to gas tank (1), in process of operation of gas generator resulting gas flows into gas tank through the main and pressure regulator keeps flowing into tank cavity, ensuring injection of fuel into engine.
EFFECT: reduced volume and mass of gas tank and pressure charging system.
