The first Rolls-Royce Turbomeca Adour Mk106 upgraded engine for RAF Jaguar aircraft has been sent to a French government facility in Saclay for altitude testing. It was despatched two days ahead of schedule, following a successful series of performance and functional tests at the Rolls-Royce facility in Bristol.

David Gower, Mk106 engineering programme manager, said: "Guaranteed thrust levels have been exceeded and the engine will undergo further thrust level checks at Saclay, as well as being checked for functionality throughout the flight envelope."

The Adour Mk106, upgraded from the Mk104 and incorporating a digital engine control amplifier, matches the latest and most powerful non-reheated Acour engine ­ the 5,990lb thrust Mk871 which powers the Hawk 100/200 and, in its US F405 designation, the T-45 Goshawk trainer ­ with the Mk811 reheat system in the Jaguar International, currently in service in harsh operating climates such as India and Oman.

The result will be an engine with improved reliability and greater life-cycle cost savings that will deliver an additional 10 per cent thrust.

The engine will run for around 400 hours at ground-based test facilities, after which flight development engines are scheduled to be supplied in the autumn of 1999 to British Aerospace, Warton, for integration and flight testing. More than 100 engines have been ordered so far, and delivery of the first production engines to the Royal Air Force is scheduled for the autumn of 2000.
