Abstract
A gas turbine engine and thrust reverse assembly having a set of outer doors movable between a stowed position and an deployed position, where the set of outer doors extends outwards from the nacelle and a set of blocker doors movable between a stowed position and an deployed position, where the set of blocker door extends into an air flow 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 an air flow conduit;
- a set of outer doors movable between a stowed position and a deployed position, where the set of outer doors extends outwards from the nacelle;
- a set of blocker doors movable between a stowed position and an deployed position, where the set of blocker door extends into the air flow conduit to deflect air outwards;
- an actuator assembly;
- and
- a link system operably coupling the actuator assembly to the set of outer doors and the set of blocker doors;
- wherein the set of blocker doors includes a greater number of doors than the number of doors in the set of outer doors, and
- during operation the actuator assembly is configured to engage the link system such that the set of outer doors and the set of blocker doors are simultaneously selectively moved between the stowed and deployed positions.
A thrust reverser assembly for a gas turbine engine including a core engine, a nacelle surrounding at least a portion of the core engine to define a bypass duct between the nacelle and the core engine, including:
- a set of outer doors movable between a stowed position and an deployed position, where the set of outer doors extends outwards from the nacelle;
- a set of blocker doors movable between a stowed position and an deployed position, where the set of blocker door extends into an air flow conduit defined by the bypass duct to deflect air outwards;
- an actuator assembly;
- and
- a link system operably coupling the actuator assembly to the set of outer doors and the set of blocker doors;
- wherein the set of blocker doors includes a greater number of doors than the number of doors in the set of outer doors, and
- during operation the actuator assembly is configured to engage the link system such that the set of outer doors and the set of blocker doors are simultaneously selectively moved between the stowed and deployed positions.
A method of operating a thrust reverser system for an aircraft, comprising:
- simultaneously deploying, by a single actuator, a set of outer doors from a stowed position to a deployed position, where the set of outer doors extend outwards from a nacelle of a gas turbine engine of the aircraft and a set of blocker doors from a stowed position to a deployed position, where the set of blocker doors extend into an air flow conduit defined by a bypass duct defined by and between the nacelle and a core engine;
- wherein the set of blocker doors includes a greater number of doors than the number of doors in the set of outer doors, and
- the set of blocker doors and the set of outer doors redirect fan duct airflow causing the airflow to exit out and forward as guided by the deployed set of outer doors.
