Rotatable component with controlled load interface

摘要

A rotatable component (50) includes a first section (52) and a second section (54) that is located radially outwards of the first section (52) with regard to an axis of rotation (A) about which the sections are co-rotatable. The sections (52, 54) are attached together at a bonded interface (56). At a perimeter region (60) of the bonded interface (56) a perimeter portion (52a) of the first section (52) has a first stiffness and a perimeter portion (54a) of the second section (54) has a second stiffness that is greater than the first stiffness.
