Seal Hook Mount Structure With Overlapped Coating

摘要

A seal is positioned radially outwardly of a compressor blade. The seal has a seal hook facing in a downstream direction. A seal mount has a mount hook for receiving the seal hook in a gap. The hook face in an upstream direction. The seal mount has an upstream portion extending from an upstream end into the gap. The mount hook extends into a web which extends in a downstream direction. A thermal barrier coating on the upstream portion of the seal mount extends to a downstream end. There is a thermal barrier coating on a radially inner surface of the mount hook, and along the web to a downstream coating end. An upstream end of the coating on the inner surface of the hook being formed axially upstream of the downstream end of the coating on the upstream portion.

1. A compressor section for use in a gas turbine engine, comprising:
a compressor blade for rotating about an axis; a seal positioned radially outwardly of said compressor blade, and said seal having a seal hook facing in a downstream direction; a seal mount, said seal mount having a mount hook for receiving said seal hook in a gap, and said mount hook facing in an upstream direction, with said seal mount having an upstream portion extending from an upstream end into said gap, said mount hook then extending into a web which extends in a downstream direction; and a thermal barrier coating on said upstream portion of said seal mount from an upstream end and extending to a downstream end, and there being thermal barrier coating on a radially inner surface of said mount hook, and along said web with an upstream end of said coating on said radially inner surface of said hook being formed axially upstream of said downstream end of said coating on said upstream portion.
