Abstract

L'invention concerne une aube pour une turbine à gaz comprenant: une partie aube comprenant une partie de bord avant et une partie de bord arrière et comprenant une section transversale fuselée; une partie de support comprenant des admissions dans lesquelles de l'air comprimé s'écoule depuis l'extérieur et supportant une extrémité de la partie aube; et une pluralité de canaux en serpentin dont une extrémité est raccordée à chaque admission et qui s'étendent en parallèle à l'intérieur de la partie aube de manière à permettre à l'air comprimé reçu par le biais de chaque admission de passer à travers ceux-ci.
