ABSTRACT:
A stator vane assembly for a gas turbine engine is provided which includes a plurality of stator vane segments and a seal ring. Each stator vane segment has an outer platform, an inner platform, and an airfoil extending between the platforms. The stator vane segments collectively form an annular structure. The seal ring includes an abradable bearing pad which extends out from an axial surface of the body of the seal ring. The seal ring is attached to a non-rotating member within the engine, positioned in close proximity to the stator vane segments. Contact, and consequent friction, between the individual stator vane segments and the abradable bearing pad causes the abradable bearing pad to abrade, thereby creating a sealing surface reflective of the opposing stator vane segments in contact with the abradable bearing pad.
