FIELD: aviation; construction of systems separating air into nitrogen and oxygen for use in flying vehicles.
SUBSTANCE: proposed system has oxygen/nitrogen generator connected with air-conditioning system by means of inlet main; generator is also connected with fuel tank pressurization system by means of outlet main for delivery of nitrogen-enriched air. Outlet main of oxygen-enriched air supply generator is connected with combustion chambers of aircraft cruise engine and is provided with control equipment and spraying unit mounted in front of combustion chamber inlet for enhancing the combustion effect. Control equipment may include gas mixer mounted in oxygen-enriched air outlet main and connected with air-conditioning system by means of bypass line for bypassing part of air from air-conditioning system to oxygen-enriched air outlet main. It is good practice to additionally connect oxygen/nitrogen generator with auxiliary power plant by means of said inlet main for intake of air before cruise mode of aircraft. Oxygen-enriched air outlet main may be additionally connected with auxiliary power plant. It is good practice to make oxygen-enriched air spraying unit in form of ejector. Oxygen-enriched air outlet main may be additionally connected with technical compartment and with auxiliary power plant compartment.
EFFECT: improved operating parameters of flying vehicle; reduction of fuel consumption and mass of engine; increased service life of combustion chamber; reduction of soot crust and carbonization; enhanced ecological parameters.
