Zusammenfassung:	A rotor assembly (56) for a piece of rotational equipment includes a rotor disk (60) configured to rotate about a rotational axis (28). The rotor disk (60) includes a first rotor attachment member (62) including a first mount slot (84A) and a second rotor attachment member (64) including a second mount slot (84B). The rotor disk (60) further includes an outer diameter surface (66) extending between the first rotor attachment member (62) and the second rotor attachment member (64). The rotor assembly (56) further includes a rotor blade (58) including an airfoil (88), a platform (90), a first mount portion (92A) retained within the first mount slot (84A), and a second mount portion (92B) retained within the second mount slot (84B). The platform (90) includes an inner platform surface (114) facing the outer diameter surface (66). The rotor disk (60) and the rotor blade (58) define a circumferential portion of a circumferentially-extending cavity (128) between the inner platform surface (114), the outer diameter surface (66), the first rotor attachment member (62), and the second rotor attachment member (64).
