NASA has selected Boeing and its industry team to lead the development and flight testing of a full-scale Transonic Truss-Braced Wing (TTBW) demonstrator airplane.

Care to share?

It’s too early to tell if Boeing’s X-plane demonstrator with the Transonic Truss-Based Wing (TTBW) will be the next Boeing single-aisle airliner, but it certainly has the ingredients for that. There are some challenges that need to be solved first before a decision on the concept can be made, David Calhoun indicated during Wednesday’s FY22 earnings call. Boeing’s X-plane demonstrator could very well become its next jet.

NASA announced a week ago that it had granted Boeing $425 million in funding to develop and build a TTBW demonstrator in 2028 under the Sustainable Flight Demonstrator (SFD) program. The airframer and partners will contribute another $725 million in funding.
