FIELD: engines and pumps.
SUBSTANCE: gas turbine engine includes a segment of ring-like block of input guide vanes, and supporting and cooling device that supports the guide vanes segment and directing the cooling medium for its cooling. The segment contains a platform at one side of the segment, at that the platform has area of rear edge including a guide, passing radially inside or outside of the rear edge area. The supporting and cooling device is located radially inside or outside the platform, and contains flange part passing radially outside or inside the supporting and cooling device. The supporting and cooling device additionally contains leaf seal and holding pin. The holding pin passes through the leaf seal, guiding and flange part to secure the segment to the supporting and cooling device to determine the radial position of the segment, and to hold the leaf seal at place to seal the contact surface between the guiding and flange part against the cooling fluid ingress.
EFFECT: invention simplifies the design of gas turbine engine.
