A METHOD OF REDUCING THE GAP BETWEEN A LINER AND A TURBINE DISTRIBUTOR OF A TURBOJET ENGINE

摘要

The method allows one to improve the seal on the inside of the rectifiers (3) of the high pressure turbine at the lower platform (6). It mainly consists of applying to the lower part of the external surface of the liner (8), a protective deposit before carrying out a filling by diffusion brazing between this liner (8) and the rectifier (3). Such a deposit, particularly of anti-adherent ceramic, makes it possible for the braze to avoid fixing the lining (8) onto the rectifier (3) at the lower platform level (6).
