Abstract

Cette invention concerne une turbine à gaz, comprenant une pluralité d'aubes de soufflante tournant autour d'un axe, chacune desdites aubes de soufflante comprenant un bord d'attaque. Ladite turbine à gaz comprend en outre une section de turbine comprenant une aube de turbine disposée le plus en arrière présentant un bord de fuite et une architecture engrenée entraînée par la section de turbine pour entraîner en rotation la pluralité d'aubes de turbine autour de l'axe. Un centre de gravité de ladite turbine à gaz est situé à une première distance axiale du bord de fuite de l'aube de turbine la plus en arrière, qui va d'environ 35 à environ 75 % d'une longueur totale entre le bord d'attaque de la pluralité d'aubes de turbine et le bord de fluide de l'aube de turbine la plus en arrière.
