Abstract

A flexible shield for fluid connectors of a gas turbine engine is disclosed. The flexible shield may comprise a flexible sleeve adapted to surround the fluid connector, and a coupling configured to secure the flexible sleeve onto a fluid tube proximate the fluid connector. A gas turbine engine employing such a flexible shield is also disclosed, as is a method of enclosing a fluid connector in a gas turbine engine using such a flexible shield.

First claim

What is claimed is:

1. A flexible shield for fluid connectors of a gas turbine engine, the fluid connector communicating fluid therethrough and connecting first and second fluid tubes, the flexible shield comprising:
a flexible sleeve surrounding the fluid connector and having a first and second end, the first and second end each being tubular, the flexible sleeve being a fabric sleeve that is folded into a double-layered structure; and a coupling securing the first and second end of the flexible sleeve to at least one of the fluid tubes.

2. The flexible shield of claim 1 , wherein the flexible sleeve is configured to withstand a temperature of about 1,300° F. (704° C.).

3. The flexible shield of claim 1 , wherein the flexible sleeve is configured to withstand a pressurized spray of about 1,500 psi.

4. The flexible shield of claim 1 , wherein the coupling includes adhesive tape and a clamp.

5. The flexible shield of claim 1 , wherein the flexible sleeve is made of ceramic material.

6. The flexible shield of claim 5 , wherein the flexible sleeve is made from ceramic oxide fibers.

7. The flexible shield of claim 1 , wherein the double-layered structure includes an outer layer, and inner layer, a first frayed end associated with the outer layer, and a second frayed end associated with the inner layer.

8. A gas turbine engine, comprising:
a compressor section;
a combustor downstream of the compressor section;
a turbine section downstream of the combustor;
at least one fluid line connector associated with the compressor section, combustor, and turbine section, the connector communicating fluid therethrough and connecting first and second fluid tubes; and
a flexible shield surrounding the fluid connector and including a flexible sleeve having a first and second end, the first and second end each being tubular, and a coupling, the flexible sleeve being a fabric sleeve that is folded into a double-layered structure, the coupling securing the first and second end of the flexible sleeve to at least one of the fluid tubes.

9. The gas turbine engine of claim 8 , wherein the flexible sleeve is configured to withstand a temperature of about 1,300° F. (704° C.).

10. The gas turbine engine of claim 8 , wherein the flexible sleeve is configured to withstand a pressurized spray of about 1,500 psi.

11. The gas turbine engine of claim 8 , wherein the coupling includes adhesive tape and a clamp.

12. The gas turbine engine of claim 8 , wherein the flexible sleeve is made of ceramic material.

13. The gas turbine engine of claim 12 , wherein the flexible sleeve is made from ceramic oxide fibers.

14. A method of enclosing a fluid connector in a gas turbine engine using a flexible shield, the fluid connector communicating a fluid therethrough and connecting first and second fluid tubes, the flexible shield including a flexible sleeve having a first and second end, the first and second end each being tubular, and a coupling, the method comprising:
manually folding a fabric sleeve into a double-layered structure to provide the flexible sleeve;
sliding the flexible sleeve over the fluid connector such that the flexible sleeve surrounds the fluid connector;
positioning the coupling around the flexible sleeve and at least one of the fluid tubes; and
attaching the flexible sleeve to the fluid tube using the coupling, the coupling securing the first and second end of the flexible sleeve to at least one of the fluid tubes.

15. The method of claim 14 , wherein the coupling includes a clamp and attaching the flexible sleeve to the fluid tube further involves tightening the clamp.

16. The method of claim 15 , wherein the coupling further includes adhesive tape, and attaching the flexible sleeve to the fluid tube further involves wrapping the adhesive tape around the flexible sleeve and fluid tube prior to tightening the clamp.

17. The method of claim 14 , further including configuring the flexible sleeve to withstand temperatures of about 1,300° F. (704° C.), and pressurized sprays of about 1,500 psi.

18. The method of claim 15 , further including manufacturing the flexible sleeve from ceramic oxide fibers.
