FIELD: engines and pumps.
SUBSTANCE: turbine stator comprises a crankcase, a sealing ring and a bracket, which connects the sealing ring with the crankcase. A bracket comprises a thermal screen arranged at the turbine side, and a radial flange for fixation on the crankcase at its one side. The bracket at the side opposite to the radial flange comprises a facility to fix the sealing ring by two radial flanges that compress the sealing ring. The thermal screen comprises, forming the space together with the bracket surface, the first sheet fixed between two radial flanges and the second sheet arranged in axial direction between the facility to fix the sealing ring and the radial flange of the bracket fixation on the crankcase. Another invention of the group relates to a gas turbine engine comprising the above stator.
EFFECT: inventions make it possible to reduce a gap between a stator and a rotor of a turbine in process of transition phases of engine operation, due to increase time of stator response to variation of temperature in a turbine flow path.
