AIRCRAFT FUEL SYSTEM

摘要

FIELD: aviation.SUBSTANCE: aircraft fuel system contains a multi-compartment fuel tank and an excessive pressure gas supply system. Cavities of the fuel tank are interconnected by fuel flow main lines with the last compartment and through it with the aircraft engine. The fuel flow main line to the last compartment is fitted with a backpressure valve. The first compartment of the fuel tank is interconnected with the excessive pressure gas supply system comprising the starting device and the gas flow limiting device. The last compartment of the fuel tank through the main line with the additional power device and the additional flow limiting device adjusted for increased value of this parameter is interconnected through the pressurization line with the excessive pressure gas supply system.EFFECT: decrease of working pressure in fuel tank compartments.2 cl, 1 dwg
