TURBOJET BYPASS ENGINE WITH AUGMENTER Russian patent published in 2009 - IPC F02K3/04 F02K3/10 

FIELD: aviation.

SUBSTANCE: invention is relate to aircraft building, in particular to turbojet bypass engines with augmenter. Turbojet bypass engine with augmenter comprises high pressure compressor, high pressure turbine and low pressure turbine. Engine is arranged with a bypass extent of m≥0.2 and diametre of inlet to engine more than 900 mm with the possibility of its operation provision at augmentation-free mode, traction from range of 7600-11000 kgf, and in augmentation mode - traction from range of 12200-18000 kgf. Part of high pressure compressor parts, high and low pressure turbines parts is made from nickel granular alloy with yield point of σ ₀₂≥95 kg/mm² and ultimate strength of σ _B≥140 kg/mm².

EFFECT: invention makes it possible to provide traction force to aircraft with such engine, with simultaneous reduction of specific engine weight due to increased frequency of rotor rotation and increased gas temperature upstream turbine, or with preservation of permanent specific mass, higher resource of engine.
