Abstract (en)
The assembly has an interposition element (16) near a collar (13) that is fixed on an flange (14) of an outer opening (7) arranged by a cavity (5) of a blade (2), where the element creates a loss of charge. The element is situated below the collar at the level of a wall (7`) of the opening, where the element is peripheral around a cooling jacket (6). The jacket has an end portion (15) opposite to the collar that is guided in another opening (8) whose wall (8`) forms a slide. Independent claims are also included for the following: (1) a method for mounting a cooling jacket in a hollow blade of a nozzle of a turbomachine (2) a method for repairing a blade and cooling jacket assembly.
