Abstract

Elément à refroidissement amélioré. Il comprend une paroi 49 limitant ce passage de gaz chauds et comportant une première partie 50 en amont de l'étranglement 40 et une seconde partie 52 en aval de cet étranglement, un conduit 54 dans la partie aval de la paroi pour acheminer du fluide de refroidissement à travers cette dernière jusqu'en un endroit situé en amont de l'étranglement et des moyens 62 pour décharger le fluide de refroidissement de ce conduit dans le passage de gaz chauds. Application au distributeur d'une turbine à gaz.
