Abstract

L'invention concerne une aube pour turbines à gaz, comportant un noyau métallique porteur assemblé avec un disque mobile et une ailette profilée en matière céramique entourant le noyau à distance, le noyau comportant à son extrémité supérieure une tête en saillie en forme de champignon, l'ailette profilée s'appuyant sur la partie inférieure de cette tête par des saillies s'avançant à l'intérieur de l'aube. Cette aube est caractérisée en ce que les saillies lc partent en forme de talons de la surface intérieure de la paroi mince de l'ailette profilée 1 dont l'épaisseur est sensiblement la même sur toute sa hauteur, et en ce qu'une masse souple 4, le cas échéant perméable à l'air, par exemple en matière ceramique mousse ou en feutre de fibres céramiques, est disposée latéralement entre le noyau 2 et l'ailette 1. L'invention est applicable aux turbines à gaz.The invention relates to a blade for gas turbines, comprising a supporting metal core assembled with a movable disc and a profiled ceramic fin surrounding the core at a distance, the core having at its upper end a protruding head in the form of a mushroom, the profiled fin resting on the lower part of this head by projections projecting inside the blade. This blade is characterized in that the projections lc start in the form of heels from the inner surface of the thin wall of the profiled fin 1, the thickness of which is substantially the same over its entire height, and in that a flexible mass 4, where appropriate permeable to air, for example of foam ceramic material or of ceramic fiber felt, is arranged laterally between the core 2 and the fin 1. The invention is applicable to gas turbines.
