Beschreibung
Zusammenfassung:	FIELD: gas-turbine engines. ^ SUBSTANCE: proposed device has flame-tube front wall mounting at least one mixing bush, fuel injector, air swirl generator, and heat shield. Inner surface of mixing bush is made in the form of Venturi tube with its diameter disposed in vicinity of front wall. Air swirl generator is mounted at inlet of mixing bush. Heat shield is mounted behind front wall. The latter and heat shield are directly attached to mixing bush with aid of different-diameter annular collars provided on outer surface of bush and separated by annular drilling. Large-diameter front collar is joined with front wall and rear collar, with heat shield. ^ EFFECT: enhanced cooling efficiency of mixing bush; enhanced reliability and service life of combustion chamber. ^ 6 cl, 7 dwg
