5% saving with better aerodynamics - at huge cost in changing every runway, taxiway, jetbridge, hanger and terminal to handle the new shape/size/layout
65% saving from new engine design based on unobtanium
- hugh3 16y agoIs that so? I'm struggling to understand how the 70% fuel usage reduction is supposed to occur just by feeding in slower-moving air. Anyone have any insight here?
- jws 16y agoI don't think that is what they mean to say. The slide on page 128 of http://aviationweek.typepad.com/files/mit_n3_final_presentation.pdf http://aviationweek.typepad.com/files/mit_n3_final_presentat... for instance breaks down the fuel savings by various changes: D8.1 configuration (double bubble) 49% Airframe Advanced Materials 8% High BPR Engines 4% .. and a long tail that might be 8% more for the engines. Now maybe the D8.1 configuration is only possible with impossible engines. I can not say.
