Zusammenfassung:	An array of rotor blades is provided. The array includes a rotor disk (22) defming a plurality of slots (23). A first rotor blade (24) that includes a first platform (34) between a first airfoil (28) and a first shank portion (32) is coupled with a first slot (23) of the rotor disk (22) via the first shank portion (32). The first rotor blade (24) further includes a pair of oppositely disposed flanges (36) positioned between the first platform (34) and the first shank portion (32) and extending beyond a longitudinal side edge (39) defined by the first platform (34). A second rotor blade, that includes a second platform (38) defming a pair of oppositely disposed overhang lips (40) and positioned between a second airfoil and a second shank portion (32), is coupled with a second slot (23) of the rotor disk (22) via the second shank portion (32). The second rotor blade is positioned adjacent to the first rotor blade such that one of the overhang lips (40) of the second platform (38) is positioned over one of the flanges (36) of the first rotor blade. Methods are also generally provided for installing rotor blades onto a rotor disk (22).
