    摘要： A cooled combustor seal having a plurality of channels enabling cooling air to pass from outside of a combustion chamber to cool an area inside the combustion chamber around the seal is disclosed. The channels may be provided through a slider, a housing, and/or a washer of the combustor seal. One set of channels or multiple of sets of channels may be provided in the combustor seal. Each of these sets of channels may be in the slider, housing, or washer. The cooled combustor seal may be used in conjunction with an igniter to purge a cavity between the seal and the igniter.

    摘要： A turbine component includes a main body with an upstream end and a downstream end. A cooling passage network is interior to the main body and has multiple cooling passages (310A, 310B). A shared passage wall (316) in the cooling passage network includes a cross passage opening (320) connecting each passage partially defined by the shared passage wall (316). The cross passage (316) further including a pressure balancing feature (330) operable to reduce a local pressure differential in a fluid pressure in each adjacent passage (310A, 310B) at the cross passage (320).

    摘要： A sealing arrangement (22) is provided at the interface between a combustor (11) and a turbine (12) of a gas turbine, whereby said turbine (12) comprises guiding vanes (14) at its inlet, which guiding vanes (14) are each mounted within said turbine (12) at their outer diameter by means of rear outer diameter vane hook (15) and are each at their inner diameter in sealing engagement by means of a front inner diameter vane tooth (23) with a honeycomb seal (24) arranged at the corresponding inner diameter part of the outlet of said combustor (11), whereby said rear outer diameter vane hook (15) allows a relative movement (16) of said guiding vane (14) in form of a rotation around said rear outer diameter vane hook (15).
    The sealing is improved by adapting said front inner diameter vane tooth (23) and the corresponding honeycomb seal (24) in their configuration to said rotating relative movement (16) of said guiding vane (14), such said the compression of said honeycomb seal (24) through transients of the gas turbine (10) is reduced.

    摘要： An example turbomachine system includes a first variable outer air seal including at least one channel. The first variable outer air seal configured to selectively communicate a fluid in response to movement of a second variable outer air seal relative to the first variable outer air seal. An example fluid control method includes selectively covering a channel inlet using a variable outer air seal to control flow through the channel.
