blisk
Sign in to savethumb|A CNC-milled, single piece axial compressor blisk A blisk (portmanteau of bladed disk), also known as an integrally bladed rotor (IBR), is a turbomachinery component consisting of a rotor disk and blades made as a single part instead of a disk assembled with individual removable blades. Blisks generally have superior aerodynamics than conventional rotors with single blades and are lighter. They may be made by additive manufacturing, casting, machining from a solid piece of material, or welding blades to a rotor disk. The term blisk is used mainly in aerospace engine design.

== History == Blisk manufacturing has been used since the mid-1980s. It was first used by Sermatech–Lehr (now known as GKN Aerospace) in 1985 for the compressors of the T700 helicopter engine. Since then, its use has continued to increase in major applications for both compressors and fan blade rotors. Examples include the Rocketdyne RS-68 rocket engine and the General Electric F110 turbofan.
