초록

A locking and sealing system is disclosed for attaching a rotor blade to a rotor blade disk in a turbojet engine. The system has a first split ring member which locks the rotor blade foot portion onto the rotor blade disk. A second split ring member is inserted between the first split ring member in a downstream flange of the rotor blade foot portions to provide a positive seal to prevent air leakage between the foot portions and the notches formed in the rotor disk.

청구항

A system for removably attaching and sealing a rotor blade to a rotor disk for a turbojet engine having a longitudinal axis comprising: (a) a plurality of substantially axially extending notches defined in the periphery of the rotor disk; (b) a foot formed on each rotor blade and adapted to be substantially axially slidably received in a notch of the rotor disk, the foot having thereon locating means to axially locate the foot with respect to the rotor disk, and a downstream flange defining a substantially circumferentially extending first groove opening...
