Superbe en tous cas !
ici, quelques trainées de condensations, vous pouvez imaginer le; les avions que vous voulez
Les diverses choses que nous avons postées dernièrment sur "ACARE" m'ont fait penser à votre "préférence" !sevrien a écrit:Salut, Louise !
Pour moi, qui couche avec les réacteurs tout le temps, , il est aise de comprendre ce genre de choix ! Un éminent membre de la famille RR Trent, aussi !
Mais, pourquoi le RR Trent 900 (raison particulière ? )?
What are we (RR) doing?
- Through detailed design optimisation, Rolls-Royce has steadily reduced NOx emissions on every new engine. The Trent 900 has the lowest certificated NOx level of any large engine and Rolls-Royce expect to improve on this with the new Trent 1000.
- Through their Research and Technology programme, Rolls-Royce are developing a new ultra-low NOx, 'lean burn' combustor which will be tested in the Environmentally Friendly Engine (EFE) programme and made available for their next generation of gas turbines.
What are the results?
- Improvements in engine emissions technology are expected to deliver three quarters of the 80 per cent target set by ACARE, with the balance coming from reductions in overall fuel-burn as a result of improved efficiencies in engine, airframe and operations.
