Abstract
A thrust reverser assembly for a gas turbine engine including a core engine, a nacelle surrounding at least a portion of the core engine defining a bypass duct between the nacelle and the core engine where an outer door movable between a stowed position and a deployed position extends outwards from the nacelle and a blocker door movable between a stowed position and an deployed position extends into an airflow conduit defined by the bypass duct to deflect air outwards.
Claims20
A gas turbine engine, comprising:
- a core engine;
- a nacelle surrounding at least a portion of the core engine;
- a bypass duct defined by and between the nacelle and the core engine and defining a fore-to-aft airflow conduit;
- an outer door movable between a stowed position and a deployed position, where the outer door extends outwards from the nacelle;
- a blocker door movable between a stowed position and a deployed position, where the blocker door extends into the airflow conduit to deflect airflow outwards;
- and
- a rotary actuator assembly operably coupled to the outer door and selectively moving the outer door between the stowed and deployed positions and operably coupled to the blocker door and selectively moving the blocker door between the stowed and deployed positions.

- a rotary actuator assembly operably coupled to the outer door and selectively moving the outer door between the stowed and deployed positions and operably coupled to the blocker door and selectively moving the blocker door between the stowed and deployed positions.
A method of operating a thrust reverser system for an aircraft, comprising:
- deploying, by a rotary actuator, an outer door from a stowed position to a deployed position, where the outer door extends outwards from a nacelle of a gas turbine engine of the aircraft;
- and
- deploying, by the rotary actuator, a blocker door from a stowed position to a deployed position, where the blocker door extends into an airflow conduit defined by a bypass duct defined by and between the nacelle and a core engine;
- and
- wherein the blocker door and outer door redirect fan duct airflow causing the airflow to exit out and forward as guided by the deployed outer door.
