Abstract

Une turbine à gaz à corps multiples comprend un corps basse pression (BP) et un corps haute pression (HP) qui peuvent tourner indépendamment autour d’un axe central. Le corps BP comprend un compresseur BP et une turbine BP. Le corps HP comprend une turbine HP et un compresseur HP. Une boîte d'entraînement des accessoires est en raccord d’entraînement avec le corps HP. Le compresseur BP est placé en relation axiale entre le compresseur HP et la boîte d'entraînement des accessoires. Un train d'engrenages accouple en relation d’entraînement le compresseur BP et la turbine BP. Le train d'engrenages est intégré à la boîte d'entraînement des accessoires.
