TheEurojet EJ200 is a militarylow-bypass turbofan used as the powerplant of theEurofighter Typhoon. The engine is largely based on theRolls-Royce XG-40 technology demonstrator, which was developed in the 1980s. The EJ200 is built by theEuroJet Turbo GmbH consortium. The EJ200 is also used in theBloodhound LSR supersonic land speed record attempting car.
Rolls-Royce began development of the XG-40 technology demonstrator engine in 1984.[2] Development costs were met by the British government (85%) and Rolls-Royce.[3]
On 2 August 1985, Italy, West Germany and the UK agreed to go ahead with the Eurofighter. The announcement of this agreement confirmed that France had chosen not to proceed as a member of the project.[4] One issue was French insistence that the aircraft be powered by theSnecma M88, in development at the same time as the XG-40.[5]

The Eurojet consortium was formed in 1986 to co-ordinate and manage the project largely based on XG-40 technology. In common with the XG-40, the EJ200 has a three-stage fan with a high pressure ratio, five-stage low-aspect-ratio high-pressure (HP) compressor, a combustor using advanced cooling and thermal protection, and single-stage HP and LP turbines with powder metallurgy discs andsingle crystal blades. A reheat system (afterburner) provides thrust augmentation. The variable area final nozzle is a convergent-divergent design.
In December 2006, Eurojet completed deliveries of the 363 EJ200s for the Tranche 1 Eurofighters.
Tranche 2 aircraft require 519 EJ200s.[6] As of December 2006[update], Eurojet was contracted to produce a total of 1,400 engines for the Eurofighter project.[7]
An EJ200 engine, together with a rocket engine, will power theBloodhound LSR for an attempt at the land speed record. The target speed is at least 1000 mph.[8]
A pair of EJ200 engines are being used in theBAE Systems Tempest demonstrator, prior to a new production engine being developed for theGlobal Combat Air Programme.
In 2009, Eurojet entered a bid, in competition with theGeneral Electric F414, to supply a thrust vectoring variant of the EJ200 to power the IndianHAL Tejas Mk2 after both the indigenous Kaveri engine and theGeneral Electric F404 used in prototypes and early production models proved to have insufficient performance. After evaluation and acceptance of the technical offer provided by both Eurojet and GE Aviation, the IAF preferred the EJ200 as it is lighter and more compact[9] but after the commercial quotes were compared in detailGE Aerospace was declared as the lowest bidder.[10][11] A second consideration by HAL was industrial offsets: if local Eurojet engine production was set up for the Tejas it would make future Eurofighter aircraft bids to India cheaper and more competitive with the Tejas whereas it was assumed the US would not allow aircraft using the engine to be sold to India. However, in October 2020 Boeing offered to sell F/A-18 aircraft to the Indian Navy which uses the same GE F414 engine.[12]

On 20 January 2015ASELSAN of Turkey and Eurojet Turbo GmbH signed a Memorandum of Understanding to collaborate on the EJ200 military turbofan engine programme.[13][14] It was envisaged that the collaboration would produce a derivative of the EJ200 with thrust vectoring for use in Turkey'sTFX 5th generation air superiority fighter programme. However, the Eurojet EJ200 was not selected for the TFX program. Instead, the TFX will use theGeneral Electric F110 engine until indigenous manufacture by TEI and TRMOTOR.[15]
The EJ200 was one of the two possible engine options (the other was the GE F414) for the C103 design for theKF-21 (formerly KF-X) programme, but the Republic of Korea Air Force chose the F414-only C109 design.
TheLiquid fly-back booster programme was cancelled.
