Problems solved by technology

Any fuel undesirably exiting through such connectors will degrade engine performance.
Not only are these metallic spray shields expensive, they also require proper installation, special tooling, and considerable time and special skills to make / install.
Moreover, the nacelle in current engine designs is substantially reduced in size and thus increases the level of difficulty in properly positioning and attaching such rigid metallic spray shields onto the fluid line systems.
This situation is made even more challenging given the tight tolerances under which such systems are manufactured, and the high number of parts used in dense locations around the fluid connectors.

Embodiment Construction

[0034]Referring now to the drawings, and with specific reference to FIG. 1, there is depicted an exemplary gas turbine engine 10 according to the present disclosure. In this example, the gas turbine engine 10 may include a compressor section 11 which may comprise, sequentially from the forefront of the gas turbine engine 10, a fan 12, a low pressure compressor 14, and a high pressure compressor 16; a combustor 18 downstream of the compressor section 11; a turbine section 19 including a high pressure turbine 20 and a low pressure turbine 22 both downstream of the combustor 18; a tail cone 24; and an exhaust nozzle 26. Further, a high pressure shaft 28 may couple the high pressure compressor 16 with the high pressure turbine 20, while a low pressure shaft 30 may couple the low pressure compressor 14 with the low pressure turbine 22. Both shafts 28 and 30 may be rotatable about an axis A. The low pressure shaft 30 may drive the fan 12 through a gear train 32. A fan nacelle 34 may surro...

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.

Description

FIELD OF THE DISCLOSURE[0001]The present disclosure generally relates to gas turbine engines and, more particularly, relates to fluid connectors within gas turbine engines.BACKGROUND OF THE DISCLOSURE[0002]A gas turbine engine commonly includes a fan section, a compressor section, a combustor, and a turbine section axially aligned sequentially through the engine. Typically, a fuel system delivers to the engine combustor a uniform flow of clean fuel at the proper pressure and in the necessary quantity to operate the engine. Despite widely varying operational conditions, the fuel supply must be adequate and continuous to meet the demands of the engine.[0003]A typical fuel system for gas turbine engines may comprise a fuel pumping arrangement, a common manifold that extends from the pumping arrangement across the top or side of the engine, and individual fuel lines that extend from the manifold to individual fuel injectors in the combustor. Further, a number of fuel delivery tubes and ...
