Abstract
A system for a thrust reverser of an aircraft includes a primary sleeve and a secondary sleeve having cascades. The secondary sleeve is coupled to a set of blocker doors. The sliding motions of the primary sleeve and the secondary sleeve are not directly coupled when each moves between its stowed and deployed positions. The sliding motion of the primary sleeve may begin at a different time and continue at a different rate from the sliding motion of the secondary sleeve.
Claims18
A thrust reverser of an aircraft comprising:
- a moveable primary sleeve;
- and
- a moveable secondary sleeve coupled to a blocker door independent of the primary sleeve, wherein the secondary sleeve drives the blocker door from a blocker door stowed position to a blocker door deployed position;
- and
- wherein a stroke associated with the primary sleeve is longer than a stroke associated with the secondary sleeve.

A thrust reverser of an aircraft comprising:
- a movable primary sleeve with an exterior surface exposed to an exterior free air stream around the thrust reverser during flight, the primary sleeve movable a first distance between a primary sleeve stowed position and a primary sleeve deployed position corresponding to reverse thrust operation;
- a movable secondary sleeve that includes a cascade for redirecting air from a fan duct during the reverse thrust operation, the secondary sleeve movable a second distance between a secondary sleeve stowed position and a secondary sleeve deployed position corresponding to the reverse thrust operation;
- and
- a blocker door coupled to the secondary sleeve, wherein the secondary sleeve is coupled to the blocker door independent of the primary sleeve;
- wherein the primary sleeve covers the cascade when the primary sleeve is in the primary sleeve stowed position, and the cascade is completely exposed to the exterior free air stream when the primary sleeve is in the primary sleeve deployed position;
- and
- wherein the first distance is different from the second distance;
- and
- wherein the secondary sleeve drives the blocker door from a blocker door stowed position to a blocker door deployed position.

A thrust reverser of an aircraft comprising:
- a movable primary sleeve with an exterior surface exposed to an exterior free air stream around the thrust reverser during flight, the primary sleeve movable between a primary sleeve stowed position and a primary sleeve deployed position corresponding to reverse thrust operation;
- a movable secondary sleeve, the secondary sleeve movable between a secondary sleeve stowed position and a secondary sleeve deployed position corresponding to the reverse thrust operation;
- a blocker door coupled to the secondary sleeve independent of the primary sleeve and movable between a blocker door stowed position and a blocker door deployed position corresponding to the reverse thrust operation wherein the blocker door redirects air through a cascade;
- wherein, when the secondary sleeve moves from the secondary sleeve stowed position to the secondary sleeve deployed position, the secondary sleeve drives the blocker door from the blocker door stowed position to the blocker door deployed position;
- and
- wherein the movable primary sleeve moves relative to the movable secondary sleeve.
