FIELD: engines and pumps.
SUBSTANCE: method of improving the thrust of a dual-flow turbojet engine, containing a fan, compressor, combustion chamber, high-pressure turbine, low-pressure turbine, internal loop nozzle and outer loop nozzle, is that guide vanes are installed in the bypass duct before the nozzle inlet. The vanes allow obtaining a low-pressure zone after the internal loop nozzle exit, which provides for increasing the internal loop nozzle outflow rate and air flow through the engine.
EFFECT: improved thrust with the same engine weight.
