Patent attributes
A gas turbine engine includes a row of blade outer air seal (BOAS) arc segments arranged around an engine axis. Each of the BOAS arc segments includes a ceramic matrix composite (CMC) body that has forward and aft flanges that project from the non-core gaspath side. An annular seal plate is located forward of the forward flange and includes a radially-extending wall, an axially-extending wall that projects forwardly from the radially-extending wall, and a nose that projects aftly from the radially-extending wall. The nose seals against the forward flange. A flexible seal is located in a recess defined by the radially-extending wall and the axially-extending wall. The flexible seal seals against a forward face of the radially-extending wall and is radially spaced apart from a radially outer face of the axially-extending wall.
