Abstract: The present disclosure provides devices and methods related to rotor disk bosses. For example, a rotor disk assembly comprises a first rotor disk, wherein the first rotor disk comprises a web, disposed between a rim and a bore. The rotor disk assembly further comprises a second rotor disk operatively coupled to the first rotor disk, an inter-disk device disposed on the second rotor disk and extending axially toward the first rotor disk, and a boss disposed on the first rotor disk, wherein the boss protrudes axially from the web toward the inter-disk device.
