  • Aircraft gas turbine having a booster bleed duct in a stator vane root element of a bypass duct
    Patent number: 9909433
    Abstract: An aircraft gas turbine has a core engine and a bypass duct surrounding the latter, where the core engine includes in its inflow zone a booster, in the area of which at least one booster bleed duct is provided for supplying an airflow from the booster into the bypass duct, and a stator vane row arranged in the bypass duct downstream of a fan. A vane root of the stator vane is designed as a structural element mounting the core engine, and the booster bleed duct is provided inside the vane root and issues downstream of the stator vane into the bypass duct.
