FIELD: engines and pumps.SUBSTANCE: annular assembly of gas turbine engine blades contains a blade segment with arched guide and blades passing from the guide, and a hollow cylinder housing with annular groove for the guide location. The guide is fixed in annular groove by means of flexible gaskets located between the guide and the groove. Each flexible gasket contains a flat basic body and brace wings passing along the both sides of the basic body at an angle to its plane. Each flexible gasket is designed with possibility of movement in circumferential direction between the first position, in which the gasket applies force in radial direction to the guide for its fixation in annular groove, and the second position, in which gasket wings occupy recesses in the assembly in order to release the guide from radial force.EFFECT: invention allows simplifying the structure of the blade segment attachment assembly to gas turbine engine housing.11 cl, 11 dwg |
