NASA and Boeing have just conducted the first test flight of their scale model of a blended wing body passenger jet the X48 B. The 500 lb model is a 8.5% scale craft that, with the aid of three turbo jet engines, can reach 10,000 feet and 120 knots. The model is part of a continuing research program that hopes to culminate in blended-wing-body commercial aircraft.
Blended wing craft are far more efficient than traditional airplanes because the entire body of BWB aircraft provides lift, isntead of just the wings. More efficient still, are flying wings, like the B2 bomber, but flying wings have far less space to store cargot and are unstable due to their lack of any stabilizing structures.
Boeing and NASA hope to have a full-scale prototype BWB craft flying between 2015 and 2020. Which is good news for all of us, as the craft would be quiet, spacious and extremely fuel efficient. And fuel efficiency in airplanes is more than just good for the planet, it's good for the wallet as well.
