摘要: An ejecting exhaust nozzle in a gas turbine engine includes a convergent section, a divergent section, extending downstream from the convergent section, and an ejector for ejecting an airflow into the core airflow is fed by a boost pump. The boost pump includes a flow mixer with a boost plane wherein a fan airflow is injected into a ram airflow and then mixed in a mixing section extending downstream from the boost plane. Varying the fan airflow to boost the ram airflow to control a boosted ram airflow pressure allows ejector operation throughout the flight envelope of the gas turbine engine.

摘要: Seal means for reducing the gas flow through the space between the opposing ends of first and second concentric axially disposed cylinders is disclosed. The seal means includes a presizeable annular leaf seal concentrically mateable with the first cylinder. In addition, the seal means includes securing means for securing the left seal to the second cylinder. In a specific embodiment, the seal means provides an effective seal between a turbine rear frame and mixer liner.
