The Eurojet EJ200 is a military low-bypass turbofan used as the powerplant of the Eurofighter Typhoon. The engine is largely based on the Rolls-Royce XG-40 technology demonstrator, which was developed in the 1980s. The EJ200 is built by the EuroJet Turbo GmbH consortium. The EJ200 is also used in the Bloodhound LSR supersonic land speed record attempting car.

Development

Rolls-Royce XG-40

Rolls-Royce began development of the XG-40 technology demonstrator engine in 1984.[1] Development costs were met by the British government (85%) and Rolls-Royce.[2]

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.[3] One issue was French insistence that the aircraft be powered by the Snecma M88, in development at the same time as the XG-40.[4]

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 and single crystal blades. A reheat system (afterburner) provides thrust augmentation. The variable area final nozzle is a convergent-divergent design.

EJ200 Mk100

In December 2006, Eurojet completed deliveries of the 363 EJ200s for the Tranche 1 Eurofighters.

EJ200 Mk101

Tranche 2 aircraft require 519 EJ200s.[5] As of December 2006, Eurojet was contracted to produce a total of 1,400 engines for the Eurofighter project.[6]

Landspeed record attempt

An EJ200 engine, together with a rocket engine, will power the Bloodhound LSR for an attempt at the land speed record. The target speed is at least 1000 mph.[7]

BAE Systems Tempest

A pair of EJ200 engines are being used in the BAE Systems Tempest demonstrator, prior to a new production engine being developed for the Global Combat Air Programme.

Failed bids / cancelled programmes

EJ230 - HAL Tejas

File:Eurojet ej2000.jpg
EJ200 Thrust vectoring prototype

In 2009, Eurojet entered a bid, in competition with the General Electric F414, to supply a thrust vectoring variant of the EJ200 to power the Indian HAL Tejas Mk2 after both the indigenous Kaveri engine and the General 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[8] but after the commercial quotes were compared in detail GE Aerospace was declared as the lowest bidder.[9][10] 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.[11]

TAI TFX

Page Module:Message box/ambox.css has no content.

On 20 January 2015, ASELSAN of Turkey and Eurojet Turbo GmbH signed a Memorandum of Understanding to collaborate on the EJ200 military turbofan engine programme.[12][13] It was envisaged that the collaboration would produce a derivative of the EJ200 with thrust vectoring for use in Turkey's TFX (now Kaan) 5th generation air superiority fighter programme. However, the Eurojet EJ200 was not selected for the TFX program. Instead, the Kaan will use the General Electric F110 engine until indigenous manufacture by TEI and TRMOTOR.[14]

KAI KF-21 Boramae

The EJ200 was one of the two possible engine options (the other was the GE F414) for the C103 design for the KF-21 (formerly KF-X) programme, but the Republic of Korea Air Force chose the F414-only C109 design.

Liquid fly-back booster

The Liquid fly-back booster programme was cancelled.

Variants

EJ2x0

Stage 1:

  • The EJ2x0 with 20% growth compared to the original EJ200. The EJ2x0 engine will have dry thrust increasing to some 72 kN (or 16,200 lbf) with a reheated output of around 103 kN (or 23,100 lbf).[15]

Stage 2:

  • The new engine plans to increase the output 30% more power compared to the original EJ200. The engine will have dry thrust of around 78 kN (or 17,500 lbf) with a reheated output of around 120 kN (or 27,000 lbf).[15]

Stage 3:

  • 20 Eurofighter Tranche 5 approved for purchase in October 2025, to be equipped with the P3Ec stage 3 engine variant.[16]
