FIELD: aircraft industry; turbojet engines.
SUBSTANCE: proposed high by-pass ratio turbojet engine with counterflow gas-air duct contains receiver with protective screen at output of low-pressure compressor. Protective screen is installed at acute angle to engine axis. Ratio of passage area of protective screen to area of gas-air duct at input of high-pressure compressor is 1.5-4.0, and ratio of area of gas-air duct at input of low-pressure compressor to area of gas-air duct at output of low-pressure compressor is 1.5-3.0.
EFFECT: improved reliability and efficiency of turbojet engine owing to prevention of icing of protective screen and reduction of its hydraulic resistance.
