FIELD: machine building.
SUBSTANCE: invention relates to inerting systems for aircraft. System (1) of inerting for aircraft, operating without collection of external air, comprises gas circuit with series-arranged air intake (2), compressor (3) and air separation module (7). At that, air separation module (7) comprises outlet (8) for oxygen-enriched gas, outlet (9) for inert gas, gas-permeable membranes, which are resistant to temperature higher than or equal to 100 °C and, preferably, 140 °C. Outlet (9) of inert gas is connected to turbine (10) for reduction of pressure and cooling of inert gas. Air circuit comprises, at compressor outlet (3), bypass line (13) of compressed air, in which motor (4) is arranged. Bypass pipeline (13) comprises part with section (14) made in size for reduction of pressure and cooling of compressed air downstream relative to electric motor (4) for cooling electric motor (4).
EFFECT: invention reduces volume, improves reliability, eliminates additional drag.
