Definitions

  • the closure element preferably projects at least partially into the core outlet opening.
  • the axis of the connecting element which generally has a cylindrical shape, coincides with the axis of the core outlet opening.
  • the area over which the connection to the blade is made is thus essentially the lateral surface of the connecting element. This is larger compared to the line that would be formed by a soldered seam, whereby a seal of the hollow interior of the turbine blade and the fixation can be ensured the connecting element is improved, ie a secure hold is guaranteed.

Abstract

L'invention concerne un procédé permettant de fermer une sortie de noyau (20, 22) d'une aube de turbine creuse (10). L'invention est caractérisée en ce qu'un élément de fermeture (24, 26) est lié à l'aube de turbine (10) au moins partiellement par liaison de friction. L'invention concerne également une aube de turbine qui présente un noyau creux (18) et au moins une sortie de noyau (20, 22). L'aube de turbine est caractérisée en ce que la sortie de noyau (20, 22) est fermée par un élément de fermeture (24, 26) qui est fixé par liaison de friction.
