FIELD: transport.
SUBSTANCE: group of inventions relates to the device and inerting method for a fuel tank, the fuel tank, an aircraft. Inertization device comprises a main tank, a separate drain volume, the gas generator, the nitrogen-rich, pipeline, the measuring sensor system, an electronic logic unit. The conduit has various valves versions to control the gas flow from generator. The aircraft fuel tank includes a main tank, the drainage volume, inerting system. The aircraft includes a fuel tank, measuring sensor system. Measuring sensor system comprises a differential pressure sensor, two pressure sensors, aircraft height sensor, air pressure sensor, temperature sensor, descent speed sensor, the fuel consumption sensor, pressure sensors and the inlet temperature supplying the generator, gas flow sensors on the generator output and buffer reservoir, gas concentration sensors at the generator and the buffer reservoir outputs. To determine the pressure the difference between the interior part of the drain volume and exterior reservoir medium for the fuel tank inerting, when lowering the difference of the value below a certain threshold the nitrogen-rich gas is fed into the discharge volume.
EFFECT: invention protects the fuel tank due to its inert gas enrichment.
