Problems solved by technology

Furthermore, when the fasteners are removed from the fairing and dome assembly, the precise dimensional relationships between the parts may be altered and thus require specialized tooling during reassembly
Therefore, replacing the combustor liner containing the cooling block becomes a time consuming and expensive process

Embodiment Construction

[0080] FIG. 1 is a schematic diagram of a gas turbine engine 10 including a low pressure compressor 12 , a high pressure compressor 14 and a combustor 16 . Engine 10 also includes a high pressure turbine 18 and a low pressure turbine 20 . Compressor 12 and turbine 20 are joined together by a first shaft 22 , while compressor 14 and turbine 18 are joined together by a second shaft 21 . In one embodiment, gas turbine engine 10 is a GE90 engine commercially available from General Electric Aircraft Engines of Cincinnati, Ohio. In another embodiment, the gas turbine engine 10 is a CF engine commercially available from General Electric Aircraft Engines of Cincinnati, Ohio.

[0081] In operation, air flows through the low-pressure compressor 12 and compressed air is supplied from the low-pressure compressor 12 to the high-pressure compressor 14 . The highly compressed air is delivered to the combustor 16 . Airflow from combustor 16 drives turbine 18 and turbine 20 and exits gas tu...

Abstract

A method for making a replacement panel for repairing a liner for a gas turbine engine combustor, the combustor having a combustion zone formed by inner and outer liners, the method comprising the steps of forming a panel from a sheet of material suitable for use in a combustor liner, forming at least one opening in the sheet of material, and applying a thermal barrier material to the replacement panel adjacent to the opening.

Description

technical field [0001] The technology described herein relates generally to gas turbine engines and, more particularly, to methods for fabricating combustor liner replacement panels. Background technique [0002] A gas turbine engine includes a compressor for compressing air that is mixed with fuel and directed into a combustor where the mixture is ignited in a combustion chamber for generating hot combustion gases. At least some known combustors include a dome assembly, cowling, and liner to direct combustion gases to a turbine that extracts energy from the combustion gases for use in driving a compressor and for generating useful work to propel an aircraft or Drive a load, such as a generator. The liner is bonded to the dome assembly through the cowling and extends downstream from the cowling to define the combustion chamber. [0003] At least some known liners include a plurality of panels joined together by riveting, bolting or welding. Portions of the panels include ...
