Futuro Boeing

Breguet's range equation is a cruel tyrant. The fuel-efficiency conscious airframe designer has only three levers -- weight, thrust and aerodynamics -- to pull, and yanking one often complicates things for the other two. At the concept stage, however, it still helps to tug upon one of Breguet's levers, just to see what happens.

So it appears with the Boeing design concept named "mid-wing aircraft", which is revealed as a patent application published on 28 June.

Boeing obviously set a challenge for itself: How to incorporate an ultra-high bypass ratio turbofan engine -- either a geared direct drive system or an open rotor -- into the 747's classic airframe, augmented by a full stretch of the upper-deck. In Breguet-speak, this is about tugging as hard as possible on the thrust lever, at the expense of weight and aerodynamics.

eh si , soprattutto quando dicono

praticamente un 380 ad elica......ma Boeing non aveva detto che un VLA come il 380 non interessava a nessuno?

Dai siamo lí, ala media e basta toglierci due motori:



Ma se i motori sotto non ci stanno piú perchè diventano troppo grossi...non si può fare ad ala alta? Ok dopo diventa quasi come il C-5..

Fino a quando non sarebbe interessato a loro
