FIELD: engines and pumps.
SUBSTANCE: gas-turbine engine with annular combustion engine includes on its inlet end an annular bottom of the chamber, through which fuel spray devices pass, and the outlet end of which is fixed by means of flexible annular flanges on radially located internal and external casings. Inlet end of chamber is connected at least to internal or external casing by means of elastically deformed bridges distributed around combustion chamber. Each of elastically deformed bridges is made in the form of bent spring plate located in circumferential direction. Besides, bridges are fixed with a bolt connection on one of internal and external casings and supported in radial direction from chamber bottom, or vice versa.
EFFECT: simpler design of gas-turbine engine with simultaneous absorption and dampening of vibrations.
