Abstract

Machine à écoulement avec refroidissement du dispositif support des ailettes directrices. On fractionne le support des ailettes directrices 1 en plusieurs segments et on suspend ces segments dans une enveloppe de carter 2 partagée parallèlement à son axe en deux moitiés, de manière à former entre le support 1 des ailettes directrices et l'enveloppe 2, un espace annulaire 5 où l'on introduit l'air de refroidissement et d'où des orifices d'amenée de fluide réfrigérant 7 débouchent dans les canaux de refroidissement 11, 11', le fluide réfrigérant, de préférence de l'air comprimé, étant enfin évacué par des orifices d'échappement 13 qui débouchent dans la veine d'écoulement 14. Application aux turbines à gaz.
