METHOD FOR CREATING AND REPAIRING TURBOMACHINE COMPONENT AND ASSOCIATED TURBOMACHINE COMPONENT Russian patent published in 2020 - IPC F01D11/00 F01D9/04 F01D11/12 F01D21/00 

FIELD: machine building.

SUBSTANCE: method of making a fixed element of a gas-turbine engine comprising a support annular wall for securing the abradable seal includes a step of fixing an abradable seal on the annular wall by soldering. At that, the method does not include the stage of the seal grinding after its fixing on the annular wall. Abrasive seal is a seal with finite dimensions. During repair of fixed element of gas turbine engine, first abradable seal, solder of seal fixation on annular wall and inner part of annular wall are removed. By means of soldering, second abradable seal is fixed on annular wall. Second abradable seal is a seal with finite dimensions, and repair does not include grinding of second seal after its attachment on annular wall. Fixed element of the gas-turbine engine contains a support annular wall for fixation of the abradable seal and at least one marking for identification of one or several repairs of the element by replacement of the seal. Abrasive seal is fixed by means of soldering on the plate, which in turn is fixed by means of soldering on the annular wall.

EFFECT: group of inventions makes it possible to simplify manufacturing and repair of fixed element of gas turbine engine including abradable seal.
