Abstract
A seal assembly for a gas turbine engine includes a seal body and a biasing support member. The seal body includes a generally annular shape that defines an outer diameter surface. The biasing support member is circumferentially disposed about the outer diameter surface of the ceramic matrix composite seal body and includes an array of spring fingers that circumferentially overlap about the biasing support member. The array of spring fingers contacts the seal body and centers the seal body relative to the centerline axis of the gas turbine engine.
