Title:
TURBINE HGP COMPONENT WITH STRESS-RELIEVING COOLING CIRCUIT
Document Type and Number:
Japanese Patent JP2023174527
Kind Code:
A
Abstract:
To relieve stress in a turbine hot gas path HGP component including a cooling circuit.SOLUTION: A turbine hot gas path HGP component 202 includes a body 210, and a cooling circuit 200 fluidly coupled to a coolant source. The cooling circuit 200 includes a plurality of sections 220 that are spaced but fluidly connected. Each section 220 includes a wall 222 defining one or more cooling passages 230, and a connector wall 258 coupling the wall 222 of a first section 260 of the plurality of sections 220 and the wall 222 of an adjacent second section 262 of the plurality of sections 220. The wall 222 of the first section 260 and the wall 222 of the adjacent second section 262 are spaced to segregate stress between the sections 220. The connector wall 258 is more flexible than the wall 222 of the first section 260, than the wall 222 of the adjacent second section 262 and than the body 210, allowing stress relief between the sections 220.SELECTED DRAWING: Figure 7
