Researchers completed TTBW high-lift tests, including stability and control checks and ground-effects evaluations, in September at NASA Langley Research Center’s 14 X 22-ft. subsonic wind tunnel in Hampton, Virginia.
Seventy years ago, Boeing was secretly preparing to gamble on whether to spend two-thirds of its post-war net profits on a radical new jet-powered long-range transport demonstrator—the Model 367-80.
To meet the required design length of the demonstrator, Boeing plans to remove an unspecified number of fuselage frames as well. This suggests the preferred donor fuselage may be from an MD-80 rather than the shorter DC-9-30-series-size 717. The fuselage will be reinforced with internal bracing from the wing to the existing structure, too, and will utilize the in situ carry-through torque boxes for the nose and main landing gears. The existing gear will be supported by a new pylon and enclosed in a new fairing.
It will be interesting if Boeing is able to pull this off, I have seen one of their X planes,not this one mind you, but a different kind when I was in California, she was in Storage. I want Boeing to pull this off because it can revolutionize the aviation industry...again.
