Abstract
An assembly for an aircraft powerplant includes a rotational load and a shaft. The shaft is coupled to the rotational load. The shaft extends along an axis between and to a first axial shaft end and a second axial shaft end. The shaft includes a slotted axial segment extending circumferentially about the axis. The slotted axial segment extends axially between and to a first segment end and a second segment end. The slotted axial segment has an outer diameter surface. The slotted axial segment forms a plurality of slots extending lengthwise through the slotted axial segment in an axial direction relative to the axis. The plurality of slots extend radially through the outer diameter surface. The plurality of slots are arranged as a circumferential array about the slotted axial segment.
