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.Ceramic core for hollow turbine blade with external perforations Ceramic core used for the manufacture of a hollow turbine blade according to the lost wax casting technique, the blade comprising at least one cavity and an external wall provided with external perforations opening at least into this cavity, core (10) comprising a plurality of pins (30) corresponding to these external perforations and intended with the core to be covered with lost wax then with molten metal in order to obtain a raw hollow turbine blade from the casting process directly integrating these external perforations without dedicated machining. Abstract: Fig. 2.
