FIELD: engines and pumps.
SUBSTANCE: proposed engine comprises casing that, together with nacelle, makes circular channel for secondary airflow developed by blower to pass through. First-circuit nozzle is secured on nacelle, behind the engine, to direct primary hot airflow developed by the engine. Said nozzle has inner wall on its one side and outer wall in contact with secondary on its opposite side. Said inner wall incorporated noise killer device and sheet element furnished with cooling air distributor along inner wall. Said noise killer device is arranged downstream of cooling air distributer. Outer wall comprises device cooling inner wall. Another invention of the set relates to first-circuit nozzle designed as described above.
EFFECT: possibility to use lower-density and lower-thermostability materials to compensate for weight of noise killer.
