Abstract

Noyau céramique pour aube de turbine creuse à perçages externes Noyau céramique utilisé pour la fabrication d’une aube de turbine creuse selon la technique de la fonderie à la cire perdue, l’aube comportant au moins une cavité et une paroi externe pourvue de perforations externes débouchant au moins dans cette cavité, noyau (10) comportant une pluralité de picots (30) correspondant à ces perforations externes et destinés avec le noyau à être recouverts de cire perdue puis de métal en fusion afin d’obtenir une aube de turbine creuse brute de fonderie intégrant directement ces perforations externes sans usinage dédié. Figure pour l’abrégé : Fig. 2.
