A foil thrust bearing forms the primary rotating interface for a film riding face seal. This face seal includes a spring system that will allow the entire assembly to translate axially relative to a static attachment. The complete assembly will form a hybrid foil/film riding face seal that shows much promise at being sufficiently flexible to enable operation in a gas turbine engine. The seal includes a flexible top plate having a non-flat surface under its working conditions, and a spring support system to allow the top plate to accommodate axial excursions and out-of-flat distortions.
