EJ200

The EJ200 was developed by an international European consortium (EUROJET Turbo GmbH) consisting of MTU, Rolls-Royce, Avio Aero and ITP Aero and is still in production today. This advanced 20,000 pound force thrust-class engine is used to power the Eurofighter and its export version, the Typhoon.

MTU's share of manufacture is about 30 percent. MTU developed the low- and high-pressure compressor and the electronic control unit (DECMU, Digital Engine Control and Monitoring Unit) and manufactures these components for all engines operated by the German Air Force (GAF) and the partner nations as well as for export customers. MTU is also responsible for the final assembly, testing and maintenance of all GAF and Austrian Armed Forces engines.

For the EJ200, MTU for the first time designed compressor stages in blisk design (blade integrated disks), which are now also being used very successfully in MTU components for commercial engines. MTU is now one of the world's leading manufacturers of this blisk technology and operates a modern and pioneering manufacturing system at its Munich site, also for compressor rotors for commercial engines.
