The Turbo-Union RB199 is an aircraft turbofan jet engine designed and built in the early 1970s by Turbo-Union, a joint venture between Rolls-Royce, MTU and FiatAvio. The RB199's sole production application is the Panavia Tornado.
Design and development
The RB199 is a modular engine, improving servicing. It was flight tested on the Avro Vulcan, the same aircraft that was used for the flight testing of Concorde’s Olympus 593. A specially built nacelle was designed that was fully representative of the Tornado fuselage and attached below the Vulcan. The aircraft first flew in this configuration in 1972.
All the installed versions of the RB199 are of three spool design and are fitted with thrust reversers for braking. The engine's compact design gives high thrust-to-weight and thrust-to-volume ratios while maintaining good handling characteristics and low fuel consumption. The RB199 has amassed over 5 million flight hours since entering service with the Royal Air Force, Luftwaffe, German Navy, Royal Saudi Air Force and Italian Air Force.
Variants and applications
- RB199 Mk 101
- Initial variant powered first Tornado IDS deliveries, with a 38.7kN (8700lb) dry thurst, 66.01kN (14840lbf) with afterburner.[1]
- RB199 Mk 103
- Powering Tornado IDS strike versions, with a thrust rating of 40.5 kN (dry) 71.2 kN (reheat)
- RB199 Mk 104
- Powering the Tornado F3 Air Defence Variant, with a thrust rating of 40.5 kN (dry) 73 kN (reheat)
- RB 199 Mk104D
- Derivative used on the BAe EAP.[1]
- RB199 Mk 105
- Powering Tornado ECR versions and applicable to IDS, with a thrust rating of 42.5 kN (dry) 74.3 kN (reheat)
- RB199-122
- A derivative of the Mk104 (originally designated Mk 104E[1]), powering the first two prototypes of the Eurofighter Typhoon (DA1 and DA2) until the initial versions of the Eurojet EJ200 were available.
