EJ200
EJ200: Powering the Eurofighter
The EJ200 is the result of a European consortium (EUROJET Turbo GmbH) comprising MTU, Rolls-Royce, Avio Aero, and ITP Aero. Providing 20,000 pounds of thrust, it is one of the most advanced engines in its class and powers the Eurofighter and its export version, the Typhoon.
MTU’s involvement in the EJ200
With a production share of 30 percent, MTU plays a major role in the Eurofighter engine. MTU is responsible for developing and manufacturing the low- and high-pressure compressors as well as the digital engine control and monitoring unit (DECMU) for all engines operated by the German Air Force, its partners, and for export customers. The company is also responsible for final assembly, testing, and repair of the engines operated by the German Air Force and the Austrian Armed Forces.
It was for the EJ200 that MTU first developed compressor stages in blisk (blade integrated disk) design; these are now used in commercial engines as well. MTU has also established itself as one of the world’s leading manufacturers of blisk technology. At its Munich site, the company operates an advanced production system for compressor rotors for commercial engines.
