Abstract

L'invention concerne une aube de rotor, refroidie, pour moteur à turbine à gaz dont la partie aérodynamiquement profilée 19 renferme un premier passage ou série de passages 21, 23, 24, 25 alimentés en fluide réfrigérant à haute pression entrant par une ouverture 36 du pied 17 de l'aube, et un second passage ou série de passages 22 alimentés en fluide réfrigérant à pression plus basse par un manchon creux 38, le fluide s'échappant desdits passages par des ouvertures 29 pour refroidir la face externe de l'aube, les diverses pressions d'admission de fluide réfrigérant lui permettant de vaincre les pressions externes différentes s'exerçant sur les diverses parties de l'aube.
