A new generation of the Adour aeroengine was introduced this week by its Anglo-French maker Rolls-Royce Turbomeca.
The engine is assembled in Bristol and Bordes, in France, near Biarritz.
The Adour 900 turbofan will be certificated in 2000 and will be offered for new and refurbished British Aerospace Hawk jet trainers and light fighters. It will also be offered for the US Navy’s T-45A Goshawk trainer, a Hawk derivative built by McDonnell Douglas.
The new turbofan will be able to operate for twice as long between overhauls compared to older Adour engines, partly because it will have a combustion chamber with a longer life.
Adour 900’s other main features will include a new design of high pressure compressor drum and the latest single crystal blading technology in rotating and static aerofoil blades throughout the turbine.
Reduced pilot workload is promised, thanks to a digital electronic control system.
