TURBOJET ENGINE WITH EJECTOR SUPERCHARGING Russian patent published in 2003 - IPC

FIELD: mechanical engineering; turbojet engines. SUBSTANCE: proposed turbojet engine has intake device, compressor, turbine, main combustion chamber arranged between compressor and turbine, outlet device and gas ejector. High- pressure channel of gas ejector is connected through mixing chamber, diffuser and compressor, and low-pressure channel communicates at one side with atmosphere, and at other side, with compressor through mixing chamber and diffuser. Pressure rise ratio in compressor compose π_c = 4-8, and after-compressor air takeoff coefficient is K_takeoff = 0,15-0,25 of air flow through compressor. EFFECT: increased thrust of turbojet engine. 3 cl, 2 dwg
