Abstract

Procédé amélioré de formation d’un modèle cire pour une aube de turbine Procédé de formation d’un modèle cire pour la réalisation d’aubes de turbine par fonderie à cire perdue, dans lequel on fournit un noyau (1), on positionne et on solidarise une coque intrados (6) et une coque extrados (7) de part et d’autre de conduits (4) du noyau adjacents au pied (2), on positionne le noyau (1) muni de la coque intrados (6) et de la coque extrados (7) dans un moule d’injection, on injecte de la cire autour dudit noyau (1) muni de la coque intrados (6) et de la coque extrados (7), de manière à former un modèle cire (8) comprenant une pale d’aube et un pied d’aube comprenant un sapin (81), la coque intrados (6) et la coque extrados (7) étant positionnées autour du noyau (1) de manière à former une partie du sapin (81) du modèle cire (8). Figure pour l’abrégé : Fig. 2.
