Blade outer air seal with cored passages

摘要

A blade outer air seal for a gas turbine engine includes a wall, a forward hook, and an aft hook. The wall extends between the forward hook and the aft hook, which are adapted to mount the blade outer air seal to a casing of the gas turbine engine. The wall includes a cored passage extending along at least a portion of the wall. The cored passage extends radially and axially through a portion of the aft hook to communicate with one or more apertures along a trailing edge of the aft hook.

1. A blade outer air seal for a gas turbine engine, comprising:
a wall extending between a forward hook and an aft hook, wherein the forward and aft hooks are adapted to mount the blade outer air seal to a casing of the gas turbine engine; wherein the wall includes at least a cored passage extending along at least a portion thereof, and wherein the cored passage extends radially and axially along a portion of the aft hook to communicate with one or more apertures along a trailing edge of the aft hook, and wherein the cored passage and the one or more apertures are configured to direct air from a first cavity to a second cavity, and wherein the first cavity is at least partially defined by the casing and disposed between the casing and the blade outer air seal, and wherein the second cavity is at least partially defined by a stator vane adjacent to the aft hook and disposed between the casing and the stator vane, and wherein the first cavity communicates with a first cooling air source and the second cavity communicates with a second cooling air source that is different from the first cooling air source.
