Problems solved by technology

However, since the location of the hot spot can be difficult to determine and can vary from engine to engine, at least some known engines have cooling apertures formed on many downstream engine components that do not end up within the hot spot, and therefore Will not ultimately experience temperature increases requiring cooling
As a result, downstream engine components not located in the hot spot are known to be overcooled to temperatures below desired temperatures, and thus large quantities of undesired cooling air are known to be exhausted into the combustion gas flow, which degrades the overall operation of the engine efficiency

Embodiment Construction

[0067] The following detailed description sets forth components and methods of making them by way of example and not limitation. This description should clearly enable one of ordinary skill in the art to make and use the component, and the description sets forth several embodiments, adaptations, variations, alternatives and uses of the component, including what is presently believed to be the best mode thereof scheme. This component is described herein as applied to a preferred embodiment, a gas turbine engine. However, it is contemplated that the components and methods of manufacture have general application in a wide variety of systems and / or various other commercial, industrial, and / or consumer applications.

[0068] figure 1 is a schematic diagram of an exemplary gas turbine engine 100 including a fan system 102 , a compressor system 104 , a combustion system 106 , a high pressure turbine system 108 and a low pressure turbine system 110 . figure 2 is a schematic diagra...

Abstract

A component for a gas turbine engine (100) is provided. The component includes a cooling aperture (194, 196) and a plug (204) filling at least a portion of the cooling aperture to prevent airflow through the cooling aperture. The plug is configured to melt at a predetermined temperature during operation of the gas turbine engine to permit airflow through the cooling aperture.

Description

technical field [0001] The field of the disclosure relates generally to components, and more particularly, to components for gas turbine engines and methods of manufacture. Background technique [0002] Many known gas turbine engines include a combustion system for mixing fuel with compressed air and igniting the mixture to produce combustion gases. Combustion gases are directed into the turbine system to drive rotation of the turbine, thereby driving a fan, compressor, and / or generator rotatably coupled to the turbine. In some gas turbine engines (eg, propulsion gas turbine engines on aircraft), combustion gases are exhausted from the turbine system into ambient air, thereby providing propulsion for the aircraft. In some other gas turbine engines, such as those in combined cycle power plants, combustion gases are directed from the turbine system into a heat recovery steam generator for steam generation. [0003] Some known combustion systems include a plurality of circumf...
