FIELD: engines and pumps.
SUBSTANCE: design of combustion chamber for gas turbine engine includes bottom part of combustion chamber, in which at least one annular hole is made, deflector installed on rear side, in flow direction, of this bottom part of combustion chamber in the above hole by means of annular guide sleeve, injection system and the means providing the possibility of misaligning the above injection system in relation to the bottom part of combustion chamber. Injection system is connected to the above hole and includes annular conical housing diverging in the flow direction and passing through the above hole. Deflector includes annular projecting edge passing inside in radial direction. Rear end, as to flow, of conical housing of injection system has annular groove open in the outward direction and located on one and the same line in radial direction with the above projecting edge of deflector so that this projecting edge has the possibility of being retracted to the above groove in case of misalignment of injection system in relation to bottom part of combustion chamber.
EFFECT: invention allows providing effective protection of injection against combustion flame.
