摘要：A rotor body ledge defines a radially inner surface. A hub extends axially fromthe rotor, and has a radially outer surface spaced from the ledge radially inner surface. Afirst distance is defined between the radially inner surface of the ledge and the radiallyouter surface of the hub. A knife edge seal has at least one pointed knife seal portion ata radially outer end. A radially inwardly extending arm portion extends from the seal, andan axially inwardly extending portion extends axially inwardly from the radially inwardlyextending portion. The axially inwardly extending portion has a radially outer face and aradially inner face, which are spaced by a second distance. The second distance is lessthan the first distance, such that the knife edge seal is free floating between the ledgeand the hub.
