Reading through flight on R-R's proposed 7E7 engine, they are looking to use a Scaled Trent 900 core which they are developing for the A380. They say that bleed air or no bleed air is not really a problem.
This is another Boeing red herring as they look to spend $10 billion on reinventing the A330. Taking this to its logical conclusion if R-R develop a super efficent engine for whatever bull Boeing are feeding the press today, it will make the A380 even more fuel concious and may even fly on an A380 before the 747 XYZstrechER IGW. In short they are cutting their own throats.
Boeing are running this as a spoiler because of the paris sucess of the A380. There is no way that a 40 year old design is going to be more efficent than a modern one. I even saw an article saying that boeing had a bolt on body kit that improves aerodynamic efficency by exploiting the area rule, woooooooooo! new thinking if you dont count the BAC lightining designed in the 50's
Boeing desperation pure and simple.
