An all-new family of turbofan engines for business jets and single-aisle airliners for many years to comeAs explained under Rolls-Royce Deutschland, the German company has for many years been working on a "clean sheet of paper" compressor of design to the very latest standard, both aerodynamically and structurally. By the time of the Paris airshow, in June 2007, Rolls-Royce plc considered the time was ripe to launch an all-new family of engines based on this core, in some cases scaled to smaller or larger sizes.
Three sizes have been announced:
- RB.282-31: The launch engine, to be rated in the 44.48 kN (10,000 lb st) class.
- RB.282-5: The next major sub-family, to be rated in the 67.27-71.17 kN (14,000-16,000 lb st) class.
- RB.282-7: The largest sub-family so far considered, to be rated in the 111.20 kN (25,000 lb st) class.
The actual launch was triggered by signature of a contract with Dassault Aviation at the start of the June 2007 Paris airshow, for the Dash-31 engine to power the French company's new SMS (Super Mid-Size) business jet in the Falcon family. Discounting the Jaguar, in which Dassault replaced Breguet as French partner, this is the first partnership between Dassault and Rolls-Royce for almost 60 years. Charles Edelstenne, the French company's Chairman and CEO, said "The new combination of Dassault and Rolls-Royce will be a winning formula".

L'analyse des perfs comparées d'un 2 arbres et d'un 2 arbres 1/2 GTF doit rester valable avec le papier de la NASA signalé par Boechien sur le fil https://avia.superforum.fr/turbofans-f9/pratt-whitney-les-nouveaux-gtf-purepower-t256-50.htm#15958
A suivre pour voir quand le RB282 sortira du bois
Bonne journée
