The first Rolls-Royce Turboméca Adour Mk106 turbofan for the upgraded Royal Air Force Sepecat Jaguar fleet has been delivered to the French engine test facility at Saclay for altitude trials, following initial tests at Rolls-Royce's Bristol plant.
The engine will be run for around 400h, with flight development engines scheduled for delivery to British Aerospace's Warton plant in the third quarter of 1999 for integration and flight tests.
"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," says Mk106 engine programme manager David Gower. The Adour Mk106 is an upgrade from the Mk104, incorporating a digital engine control and the Mk811 reheat system .
