ABSTRACT:
An apparatus and method for axially retaining rotor blades on a rotor disk wherein a integral split ring blade retainer is installed in a groove on a rotor disk and compressed to allow installation of rotor blades into slots on the rotor disk and releasing of the split ring blade retainer from compression causes the split ring blade retainer to engage a hook on the rotor blade and the groove on the rotor disk to react axial loads and prevent axial movement of the rotor blade with relation to the rotor disk.
