The GEnx already uses blisks in some stages.Įngine manufacturer EDAC Technologies, now Hanwha Aerospace USA is the number one global supplier of blisk and IBR manufacturing in the world. General Electric's Passport (formerly "TechX") engine uses blisks for both its main 52" fan as well as for 5 of its 10 high pressure turbine stages. PowerJet SaM146 engines used on Sukhoi Superjet 100s are also equipped with blisks. Įngine manufacturer CFM International is using blisk technology in the compressor section of its Leap-X demonstrator engine program, which has completed full-scale rig testing. The F-35B variant of the Joint Strike Fighter uses blisks to achieve short take-off and vertical landing. Examples include the Rocketdyne RS-68 rocket engine and the General Electric F110 turbofan. Since then, its use has continued to increase in major applications for both compressors and fan blade rotors. It was first used by Sermatech-Lehr (now known as GKN Aerospace ) in 1985 for the compressors of the T700 helicopter engine. ![]() Blisks may also be known as integrally bladed rotors ( IBR).īlisk manufacturing has been used since the mid-1980s. The term is used mainly in aerospace engine design. They may be additively manufactured, integrally cast, machined from a solid piece of material, or made by welding individual blades to a rotor disk. Each blisk consists of a single part instead of disk assembled with individual removable blades. Blisks generally have better aerodynamics than conventional rotors with single blades and are lighter. It serves as a critical component of the engine compressor to allow a sufficient quantity of compressed air to enter the engine for combustion to occur. A CNC-milled, single piece axial compressor bliskĪ blisk ( portmanteau of bladed disk) is a turbomachine component comprising both rotor disk and blades.
