Abstract
A seal assembly for a gas turbine engine according to an example of the present disclosure includes, among other things, a seal that has a sealing portion that extends circumferentially between first and second mate faces and an engagement portion along the first mate face. A support has an interface portion that extends from a mounting portion. The interface portion abuts the engagement portion to limit relative movement, and the mounting portion defines an aperture that receives a fastener to mechanically attach the mounting portion to an engine static structure. A portion of the fastener is circumferentially aligned with the first mate face. The fastener defines a first cooling passage that delivers cooling flow at a location adjacent to the first mate face.
