Abstract

A thrust reverser system includes a translating cascade, a blocker door, and a drive link. The drive link may be pivotably coupled to the translating cascade and the blocker door. The translating cascade may be coupled to a translating sleeve of a nacelle. The drive link may cause the blocker door to deploy in response to the translating cascade moving in an aft direction. The blocker door may be pivotably coupled to a fixed aft portion of the nacelle.

First claim

What is claimed is:

1. A thrust reverser system comprising:
a translating cascade coupled to a translating sleeve;
a fixed forward portion and a fixed aft portion, wherein the fixed forward portion and the fixed aft portion form a portion of a nacelle loft line, and wherein the translating sleeve is located between the fixed forward portion and the fixed aft portion;
a blocker door configured to pivot about an aft end of the blocker door; and
a drive link operatively coupled to the translating cascade and the blocker door.

2. The thrust reverser system of claim 1 , wherein the blocker door is pivotably coupled to the fixed aft portion.

3. The thrust reverser system of claim 1 , wherein the drive link is stowed within a fan cowl.

4. The thrust reverser system of claim 1 , wherein the drive link is coupled to a forward end of the blocker door.

5. The thrust reverser system of claim 1 , wherein the drive link is configured to deploy the blocker door in response to the translating cascade moving in an aft direction.

6. The thrust reverser system of claim 1 , wherein the nacelle comprises a split sleeve.

7. The thrust reverser system of claim 1 , wherein the blocker door forms a portion of the nacelle loft line.

8. A nacelle having a thrust reverser comprising:
a fixed forward portion;
a fixed aft portion, wherein the fixed forward portion and the fixed aft portion form a portion of a nacelle loft line;
a translating sleeve located between the fixed forward portion and the fixed aft portion;
a translating cascade coupled to the translating sleeve; and
a blocker door coupled to the translating cascade by a drive link, wherein the blocker door is configured to rotate about a pivot located at an aft end of the blocker door.

9. The nacelle of claim 8 , wherein the blocker door is pivotably coupled to the fixed aft portion.

10. The nacelle of claim 8 , wherein the drive link is configured to be stowed in the fixed forward portion.

11. The nacelle of claim 8 , wherein the drive link is coupled to a forward end of the blocker door.

12. The nacelle of claim 8 , wherein the drive link is configured to deploy the blocker door in response to the translating cascade moving in an aft direction.

13. The nacelle of claim 8 , wherein the translating sleeve is configured to overlap the fixed aft portion in a deployed position.

14. The nacelle of claim 8 , further comprising a forward seal between the fixed forward portion and the translating sleeve, and an aft seal between the translating sleeve and the fixed aft portion.
