Abstract

La présente invention concerne un moteur à turbine à gaz à plusieurs étages comportant un conduit inter-compresseur reliant un compresseur basse pression à un étage compresseur suivant. Ce moteur présente un perfectionnement de l'organe de purge (161) permettant de purger le conduit d'une quantité variable d'air lorsque le moteur fonctionne à charge partielle. L'organe de purge (161) comporte, d'une part un dispositif d'ouverture disposé en périphérie de la paroi externe du conduit, et d'autre part des déflecteurs d'air articulés (161) détournant vers l'extérieur le flux d'air intérieur du conduit, au travers d'ouvertures dans la paroi externe du conduit. Selon la présente invention, les déflecteurs d'air sont des volets (161) formant un alignement circonférentiel, des éléments d'obturation étanches suivant le mouvement des volets et reliant les rives latérales de volets consécutifs (161) de façon à empêcher l'écoulement radial de l'air entre des volets consécutifs.
