FIELD: aircraft industry.
SUBSTANCE: proposed high-by-pass ratio turbojet engine has outer circuit reverse assembly including deflecting grid, fixed and movable housings with sealing member in between, turnable flaps hinge-connected by two-link lever mechanism with fixed housing and with contact pads, and also gas generator fairing. Outer and inner movable housing are interconnected, and they form outer edge of nozzle adjustable in area. Fairing of gas generator at nozzle exit section is made conical, with angle of generatrix equal to 15-30°C. Additional sealing device is installed lower from sealing member in direction of flow on outer surface of inner movable housing. Slot space open towards nozzle is made between fixed and outer movable housings. Ratio of radial height of entry face to radial clearance between inner movable housing and deflecting grid of reverse assembly is 0.6-2.
EFFECT: improved reliability of turbojet engine owing to reduction of gas temperature before turbine at take-off.
