Abstract

A thrust reverser may comprise translating sleeve panel. A first articulating slider and a second articulating slider may be located at a circumferential end of the translating sleeve panel. Each of the first articulating slider and the second articulating slider may include a slider bar and a slider ball. The slider ball may be attached to the translating sleeve panel and located in a spherical opening defined by the slider bar.

First claim

What is claimed is:

1. A thrust reverser, comprising:
a first translating sleeve panel;
a first articulating slider located at a circumferential end of the first translating sleeve panel, the first articulating slider including a first slider bar and a first slider ball, wherein the first slider ball is attached to the first translating sleeve panel and is located in a first spherical opening defined by the first slider bar;
a second articulating slider located at the circumferential end of the first translating sleeve panel, the second articulating slider including a second slider bar and a second slider ball, wherein the second slider ball is attached to the first translating sleeve panel and is located in a second spherical opening defined by the second slider bar;
a hinge beam located proximate the circumferential end of the first translating sleeve panel;
a second translating sleeve panel located radially inward of the first translating sleeve panel; and
a primary slider coupled to the second translating sleeve panel, wherein an axial length of the primary slider is greater than the axial length measured between a forward end of the first slider bar and an aft end of the second slider bar.

2. The thrust reverser of claim 1 , wherein the first articulating slider further includes a first neck extending between the first slider ball and the circumferential end of the first translating sleeve panel, and wherein the second articulating slider further includes a second neck extending between the second slider ball and the circumferential end of the first translating sleeve panel.

3. The thrust reverser of claim 2 , wherein the first neck is located through a first bar slot defined by the first slider bar and the second neck is located through a second bar slot defined by the second slider bar.

4. The thrust reverser of claim 3 , wherein the first translating sleeve panel translates relative to the hinge beam.

5. The thrust reverser of claim 4 , further comprising a secondary track coupled to the hinge beam, wherein the first slider bar and the second slider bar are located in a secondary track channel defined by the secondary track.

6. The thrust reverser of claim 4 , wherein the first slider bar and the second slider bar are located in a secondary track channel defined by the hinge beam.

7. The thrust reverser of claim 4 , wherein the second translating sleeve panel is configured to translate relative to the hinge beam.

8. The thrust reverser of claim 7 , further comprising a primary slider track coupled to the hinge beam, wherein the primary slider is located in a primary track channel defined by the primary slider track.

9. The thrust reverser of claim 7 , wherein the primary slider is located in a primary track channel defined by the hinge beam.

10. A nacelle, comprising:
an inlet;
a fan cowl; and
a thrust reverser including:
a first translating sleeve panel;
a first articulating slider located at a circumferential end of the first translating sleeve panel, the first articulating slider including a first slider bar and a first slider ball, wherein the first slider ball is attached to the first translating sleeve panel and is located in a first spherical opening defined by the first slider bar;
a second articulating slider located at the circumferential end of the first translating sleeve panel, the second articulating slider including a second slider bar and a second slider ball, wherein the second slider ball is attached to the first translating sleeve panel and located in a second spherical opening defined by the second slider bar;
a hinge beam located proximate the circumferential end of the first translating sleeve panel;
a second translating sleeve panel located radially inward of the first translating sleeve panel; and
a primary slider coupled to the second translating sleeve panel, wherein an axial length of the primary slider is greater than the axial length measured between a forward end of the first slider bar and an aft end of the second slider bar.

11. The nacelle of claim 10 , wherein the first articulating slider further includes a first neck extending between the first slider ball and the circumferential end of the first translating sleeve panel, and the first neck being located through a first bar slot defined by the first slider bar, and wherein the second articulating slider further includes a second neck extending between the second slider ball and the circumferential end of the first translating sleeve panel, and the second neck being located through a second bar slot defined by the second slider bar.

12. The nacelle of claim 10 , wherein the first translating sleeve panel translates relative to the hinge beam, wherein the first slider bar and the second slider bar are located in a secondary track channel defined by at least one of the hinge beam or a secondary track coupled to the hinge beam.

13. The nacelle of claim 12 , wherein the second translating sleeve panel is configured to translate relative to the hinge beam.

14. The nacelle of claim 13 , wherein the primary slider is located in a primary track channel defined by the hinge beam or a primary slider track coupled to the hinge beam.
