ROTOR ASSEMBLY

Abstract:

A rotor assembly for a piece of rotational equipment includes a rotor disk configured to rotate about a rotational axis. The rotor disclose includes a first rotor attachment member including a first mount slot and a second rotor attachment member including a second mount slot. The rotor disk further includes an outer diameter surface extending between the first rotor attachment member and the second rotor attachment member. The rotor assembly further includes a rotor blade including an airfoil, a platform, a first mount portion retained within the first mount slot, and a second mount portion retained within the second mount slot. The platform includes an inner platform surface facing the outer diameter surface. The rotor disk and the rotor blade define a circumferential portion of a circumferentially-extending cavity between the inner platform surface, the outer diameter surface, the first rotor attachment member, and the second rotor attachment member.
