Abstract

L'invention concerne un dispositif perfectionné de refroidissement des éléments mobiles un moteur à turbine à gaz. Une chambre annulaire interne 28, alimentée en air réfrigérant provenant directement de la sortie 22 du compresseur 18, conduit cet air au voisinage de la turbine 30 où il se divise en une fraction sortant par les aubes 33 pour gagner les passages 38 de refroidissement des aubes de turbine 31, et en une fraction sortant par les aubes de turbulence 39 lui impartissant un mouvement de même sens et de même vitesse que l'arbre d'accouplement 15, et venant refroidir cet arbre en cheminant à contre-courant pour rejoindre le courant d'air principal du moteur par l'entrefer 20 à la sortie du compresseur.
