  • Publication number: 20190048764
    Abstract: A tensioner assembly for an engine timing drive includes a tensioner with a tensioner body having a fastener opening and defining a cavity with a plunger opening. A plunger is disposed in the cavity and a removable pin restrains the plunger in the cavity. The plunger is configured to be biased out of the plunger opening when the pin is removed. A protuberance extends outward from the tensioner body and is adapted to receive an applied torque. The tensioner body is configured to pivot about a center axis of the fastener opening in response to a predetermined torque applied to the protuberance. A method of assembling an engine timing drive includes applying a predetermined torque to a protuberance of a tensioner that is pivotably mounted to a cylinder block to rotate the tensioner toward a rotatable device such that the tensioner applies a predetermined load to the rotatable device.

  • Patent number: 5435127
    Abstract: 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.
