Abstract
An annular blade retention plate for axially retaining rotor blades within slots of a rotor disk. The plate includes an annular plate web extending radially outwardly from a radially inner plate hub to a plate rim and an annular radially outwardly open outer channel in a radially outwardly facing outer surface of the rim. A sealing ring is received within the outer channel and the sealing ring has axial rectangularly shaped cross-sections. An annular axially forwardly open inner channel in an annular ridge on a forward plate face of the plate web has an annular seal wire received therein. In a rotor assembly having a rotor disk supporting a plurality of circumferentially spaced apart rotor blades mounted in corresponding axially extending slots and the plate mounted to the rotor disk the sealing ring is in sealing engagement with radially inwardly facing surfaces of blade platforms of the blades.
