The Eurojet EJ200 turbofan with its maximum thrust of 90kN (with reheat) is the powerplant for the Eurofighter Typhoon for which Eurojet was contracted in December 2006 to produce a total of 1,400 engines. The Eurojet consortium was formed in 1986 to co-ordinate and manage the project and has worked on this three-stage fan with a high pressure ratio, five-stage low-aspect-ratio high-pressure (HP) compressor with active tip-clearance control. Its combustor uses advanced cooling and thermal protection, and single-stage HP and low-pressure (LP) turbines with PM discs and low-density single crystal blades. The reheat system provides thrust augmentation and the variable area final nozzle is of a convergent-divergent design.
