Abstract

The present disclosure relates generally to an aerodynamic track fairing assembly used on an engine nacelle, the track fairing assembly positionable on the aft section of the engine nacelle, the aerodynamic track fairing assembly including: an upper section extending toward an aft end of the aft section of the engine nacelle; a bottom section extending toward the aft end of the aft section of the engine nacelle, the bottom section affixed to the upper section to form a track cavity therebetween; and a fairing fitting disposed within the track cavity and affixed to the bottom section.

First claim

What is claimed is:

1. A turbine engine nacelle including an aft section comprising:
an aerodynamic track fairing assembly located on the aft section of the nacelle, the aerodynamic track fairing comprising:
an upper section extending toward an aft end of the aft section of the nacelle, the upper section including an upper portion end;
a bottom section extending toward the aft end of the aft section of the nacelle, the bottom section including a bottom section end, and a bottom section interior surface;
wherein the upper portion end is affixed to bottom section end to form a track cavity between the upper section and the bottom section;
a fairing fitting disposed within the track cavity and affixed to the bottom section interior surface, wherein the fairing fitting is enclosed by the upper section and the bottom section; and
a pylon fitting affixed to the engine pylon, wherein the pylon fitting is disposed within the track cavity and located adjacent to the fairing fitting.

2. The nacelle of claim 1 , wherein the aerodynamic track fairing assembly is positionable against an aft end of an engine pylon.

3. The nacelle of claim 1 , wherein a gap is formed between the pylon fitting and the fairing fitting.

4. The nacelle of claim 3 , further comprising a seal disposed adjacent to the gap.

5. The nacelle of claim 1 , wherein a portion of the upper section includes a curvature.

6. The nacelle of claim 1 , wherein a portion of the bottom section includes a curvature.

7. A turbine engine nacelle including an aft comprising:
an aerodynamic track fairing assembly located on the aft section of the nacelle, the aerodynamic track fairing comprising:
an upper section extending toward an aft end of the aft section of the nacelle, the upper section including an upper portion end;
a bottom section extending toward the aft end of the aft section of the nacelle, the bottom section including a bottom section end, and a bottom section interior surface;
wherein the upper portion end is affixed to bottom section end to form a track cavity between the upper section and the bottom section;
a fairing fitting disposed within the track cavity and affixed to the bottom section interior surface, wherein the fairing fitting is enclosed by the upper section and the bottom section, wherein the siring fitting comprises a substantially I-shaped cross-section.

8. A turbine engine nacelle including an aft section comprising:
an aerodynamic track fairing assembly located on the aft section of the nacelle, the aerodynamic track fairing comprising:
an upper section extending toward an aft end of the aft section of the nacelle, the upper section including an upper portion end;
a bottom section extending toward the aft end of the aft section of the nacelle, the bottom section including a bottom section end, and a bottom section interior surface;
wherein the upper portion end is affixes to bottom section end to form a track cavity between the upper section and the bottom section;
a fairing fitting disposed within the track cavity and affixed to the bottom section interior surface, wherein the fairing fitting is enclosed by the upper section and the bottom section, wherein the pylon fitting comprises a substantially L-shaped cross section.

9. A gas turbine engine comprising:
a nacelle including an aft section; and
an aerodynamic track fairing assembly located on the aft section of the nacelle, the aerodynamic track fairing comprising:
an upper section extending toward an aft end of the aft section of the nacelle, the upper section including an upper portion aft end;
a bottom section extending toward the aft end of the aft section of the nacelle, the bottom section including a bottom section aft end, and a bottom section interior surface;
wherein the upper portion end is affixed to bottom section aft end to form a track cavity between the upper section and the bottom section;
a fairing fitting disposed within the track cavity and affixed to the bottom section interior surface, wherein the fairing fitting is enclosed by the upper section and the bottom section; and
a pylon fitting affixed to the engine pylon, wherein the pylon fitting is disposed within the track cavity and located adjacent to the fairing fitting.

10. The gas turbine engine of claim 9 , wherein the aerodynamic track fairing assembly is positionable against an aft end of an engine pylon.

11. The gas turbine engine of claim 9 , wherein a gap is formed between the pylon fitting and the fairing fitting.

12. The gas turbine engine of claim 11 , further comprising a seal disposed adjacent to the gap.

13. The gas turbine engine of claim 9 , wherein a portion of the upper section includes a curvature.

14. The gas turbine engine of claim 9 , wherein a portion of the bottom section includes a curvature.

15. The gas turbine engine of claim 9 , wherein the fairing fitting comprises a substantially I-shaped cross-section.

16. The gas turbine engine of claim 9 , wherein the pylon fitting comprises a substantially L-shaped cross section.
