Adour Mk 102


The Rolls-Royce Turbomeca Adour is a two-shaft turbofan aircraft engine developed by Rolls-Royce Turbomeca Limited, a joint subsidiary of Rolls-Royce (UK) and Turbomeca (France). The Adour is a turbofan engine developed primarily to power the Anglo-French SEPECAT Jaguar fighter-bomber, achieving its first successful test run in 1968.

Ten prototype engines were built for testing by both Rolls-Royce and Turbomeca, and 25 were built as development engines for the Jaguar prototypes,

Named after the Adour, a river in south western France, it was produced in versions with or without reheat.

As of July 2009 more than 2,800 Adours have been produced, for over 20 different armed forces with total flying hours reaching 8 million in December 2009. The U.S. military designation for this engine is the F405-RR-401 (a derivative of the Adour Mk 871), which is used to power the fleet of Boeing / BAE Systems T-45 Goshawk trainer jets of the US Navy.


Reheated (Afterburning)
Adour Mk 101 - First production variant for the Jaguar, 40 built.

Adour Mk 102 - Second production variant with the addition of part-throttle reheat.

Adour Mk 104

Adour Mk 106 - Replacement for the Jaguar's Mk104 engine (developed from the Adour 871) with a reheat section. The RAF refitted its fleet with this engine as part of the GR3 upgrade. In May 2007, following the retirement of the last 16 Jaguars from No. 6 Squadron RAF, based at RAF Coningsby, the Adour 106 has been phased out of RAF service.

TF40-IHI-801A - Licence-built version of Mk 801 by Ishikawajima-Harima for Mitsubishi F-1 & T-2 (JASDF)

Adour Mk 804 - Licence-built by HAL for Indian Air Force phase 2 Jaguars

Adour Mk 811 - Licence-built by HAL for Indian Air Force phase 3 to 6 Jaguars

Adour Mk 821 - Engine upgrade of Mk804 and Mk811 engines, under development, for Indian Air Force Jaguar aircraft.

Dry (Non-afterburning)

Adour Mk 951 - Designed for the latest versions of the BAE Hawk and powering the BAE Taranis and Dassault nEUROn UCAV technology demonstrators. The Adour Mk 951 is a more fundamental redesign than the Adour Mk 106, with improved performance (rated at 6,500 lbf (29,000 N) thrust) and up to twice the service life of the 871. It features an all-new fan and combustor, revised HP and LP turbines, and introduces Full Authority Digital Engine Control (FADEC). The Mk 951 was certified in 2005.

F405-RR-402 - Upgrade of F405-RR-401, incorporating Mk 951 technology, certified 2008. Expected entry into service 2012.
