A non-integral rotor blade platform for a rotary machine is disclosed. Various construction details are developed which disclose a one-piece, non-integral rotor blade platform retained to a live rim area of a disk. In one embodiment, a rotor blade assembly (48) is comprised of a plurality of rotor blades (54) disposed on a disk (44), a plurality of platforms (60), each platform disposed between adjacent rotor blades, and a front cover plate (56) and rear cover plate (58) which, in conjunction, retain the platforms to the disk. In an alternative embodiment, each platform (102) has a supplemental mechanical fastener means (100) to provide additional retention of the platforms to a disk (104).
