COMBUSTION CHAMBER Russian patent published in 2002 - IPC

FIELD: mechanical engineering; gas turbine engines. SUBSTANCE: proposed combustion chamber designed mainly for gas turbine engines and plants has flue to which ring lips are connected to direct cooling air which passes through holes in flue walls. Flue and lips are made of different materials. Modulus of elasticity and coefficient of linear thermal expansion of material used for making lips are less than modulus of elasticity and coefficient of linear thermal expansion of flue housing material. At large temperature differences between lips and wall of flue (200-400 C) ratio protected by invention is maintained. EFFECT: increased service life of combustion chamber. 1 dwg
