Abstract
A cooled gas turbine blade includes a foundry part and a longitudinal sleeve obtained by the forming of metal sheet. The foundry part includes a longitudinal body provided with a longitudinal cavity with first and second apertures at its ends. The sleeve is mounted in the cavity being held therein by soldering or brazing to the wall of the first aperture, and an end portion of which is free to slide in the second slide-forming aperture. The end portion and the slide are in sliding contact relatively to surfaces formed by machining. A sealing insert can be positioned between the end portion of the sleeve and the wall of the second aperture. This insert can be integral with the sleeve.
