Rotating vane seal with cooling air passages

摘要

An inner diameter vane seal (42) for a gas turbine engine (10) comprises an annular, ring-like body having inner and outer diameter rims (56, 54), forward and aft faces (47A, 47B) and an air passage (74). The outer diameter rim (54) extends circumferentially for engaging inner diameter ends (73) of stator vanes (38). The inner diameter rim (56) extends circumferentially and is spaced radially from the outer diameter rim (54). The forward and aft faces (47A, 47B) extend radially between the outer diameter rim (54) and the inner diameter rim (56). The air passage (74) extends from the forward face (47A) to the aft face (47B) between the inner and outer diameter rims (56, 54).
