  • ENDWALL PLUG COOLING SYSTEM
    Publication number: 20240011414
    Abstract: A cooling system includes a nozzle guide vane endwall. The nozzle guide vane endwall includes a first wall and a second wall. The first wall includes a first opening that extends completely through the first wall into a primary flow path of a high-pressure turbine. The second wall includes a second opening and a third opening that extend completely through the second wall into an inner passageway of the nozzle guide vane endwall. The inner passageway is configured to direct a cooling fluid to the first opening and/or the second opening via at least the third opening. The first and second opening are configured to receive a plug or a probe.
