ABSTRACT:
A rotor assembly including a spool and a plurality of radially extending rotor blades mounted in a groove provided circumferentially of the spool is described. The groove includes a pair of inwardly extending flanges which define a throat area narrower than the groove. A stacking hole extends radially and communicates with the groove to allow the rotor blade members to be individually mounted to the spool. The locking device for retaining the rotor blades in the spool includes a C-shaped spring adapted to urge against the roots of each rotor blade in the groove and a locking protrusion adapted to engage in the stacking hole and in an opening formed in the platforms of two adjacent blades straddling the stacking hole whereby the locking device abuts against the ends of the flanges in the stacking hole and retains the rotor blades against circumferential movement. A pair of anchor members can also be provided near the ends of the C-shaped spring member for engagement in the root of pairs of blades.
