Title:
EXHAUST FRAME DIFFERENTIAL COOLING SYSTEM
Document Type and Number:
Japanese Patent JP2023100250
Kind Code:
A
Abstract:
To provide an exhaust frame differential cooling system of a gas turbine engine to reduce a temperature differential along a compressor and/or a turbine to minimize centerline eccentricity of a shaft.SOLUTION: An exhaust frame differential cooling system 100 includes: a plurality of compressor temperature sensors 190, 200 positioned about a compressor and/or a plurality of turbine temperature sensors 210, 220 positioned about a turbine; an exhaust frame 110 including an inner barrel with a bearing tunnel for a shaft, an outer barrel, and a plurality of struts extending from the inner barrel to the outer barrel; a blower 170; and a cooling air metering system 130 that provides cooling air 120 from the blower 170 to the bearing tunnel and through the inner barrel, the struts and the outer barrel in response to the temperature differential being determined along the compressor and/or the turbine.SELECTED DRAWING: Figure 4
