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.
In a gas turbine engine including, in serial flow relationship, an engine inlet, a fan, a core engine defining a core flow path for core airflow, and an ejecting exhaust nozzle for obtaining thrust from said core airflow, said ejecting exhaust nozzle comprising:
An ejecting exhaust nozzle as claimed in claim I further comprising means for controlling the ratio of said fan airflow to said ram airflow.
In a gas turbine engine including, in serial flow relationship, an engine inlet, a core engine, including a compressor, defining a core flow path for core airflow, and an ejecting exhaust nozzle for obtaining thrust from said core airflow, said ejecting exhaust nozzle comprising:
In a gas turbine engine including, in serial flow relationship, an engine inlet, a core engine defining a core flow path for core airflow, and an ejecting exhaust nozzle including a convergent section and a divergent section for obtaining thrust from said core airflow, a method of ejecting air into the divergent section core airflow comprising:
