Abstract
Official abstract text for this publication.
A turbine component for use in a hot gas path of a gas turbine engine. The turbine component may include an outer surface, an internal cooling circuit, an adaptive cooling pathway in communication with the internal cooling circuit and extending through the outer surface, and a cooling plug having two or more materials positioned within the adaptive cooling pathway.
First claim
Opening claim text (preview).
We claim: 1. A turbine component for use in a hot gas path of a gas turbine engine, comprising: an outer surface; an internal cooling circuit; an adaptive cooling pathway in communication with the internal cooling circuit and extending through the outer surface; and a cooling plug positioned within the adaptive cooling pathway, wherein the cooling plug comprises a first material and a second material, wherein the first material comprises a lower predetermined melting temperature than the second material, wherein the first material and the second material comprise a swirled configuration. 2. A method of cooling a turbine component operating in a hot gas path, comprising: positioning an adaptive cooling pathway in communication with an internal cooling circuit through an outer surface of the turbine component; positioning a multi-material cooling plug in the adaptive cooling pathway, wherein the multi-material cooling plug comprises an outer material comprising a tubular casing surrounding a solid inner material, wherein the outer material is disposed around a circumference of the inner material, wherein the outer material is disposed between the inner material and a wall of the adaptive cooling pathway, wherein the outer material is not disposed on a surface of the inner material facing away from the adaptive cooling pathway, wherein the outer material comprises a lower predetermined melting temperature than the inner material; releasing the multi-material cooling plug if a predetermined temperature of the outer material of the multi-material cooling plug is reached or exceeded; and flowing a cooling medium through the adaptive cooling pathway to cool a localized portion of the outer surface.
