Blisk

The term "blisk" is an acronym composed of the words "blade" and "disk". A blisk is an integrally bladed rotor disk, meaning that blade roots and blade locating slots are no longer required. Major advantages: the disk shape can be optimized for low rim loads and the component weight is reduced.
