NASA will invest $425 million to help Boeing develop a demonstrator aircraft for its Transonic Truss-Braced Wing design, which the space agency hopes will improve the fuel efficiency of commercial ...

This design, known as transonic truss-braced wing (TTBW), could in theory allow the plane to generate more lift, thus reducing the amount of fuel it needs for certain portions of the flight.

With a US$425-million cash injection from NASA, Boeing will build and test a full-sized airliner based on its transonic truss-braced wing (TTBW) concept, using long, thin, strut-braced wings to ...

Boeing will work with NASA to build, test and fly a full-scale demonstrator aircraft based on Boeing’s Transonic Truss-Braced Wing (TTBW) design. First flight is scheduled for 2028, part of a ...

Boeing is pumping the brakes on its experimental X-66 flight demonstrator.. The aircraft—being developed with a transonic truss-braced wing—is on “pause for later consideration” after ...

It will work with Boeing to design and build the new aircraft, which should be more fuel-efficient and could use up to 30 percent less fuel than current aircraft designs.

NASA's Sustainable Flight Demonstrator (SFD) project recently concluded wind tunnel tests of its X-66 semi-span model in partnership with Boeing. The model, designed to represent half the aircraft ...

Just like with the X-59, the main thing pushing the X-66A project forward is not necessarily some piece of innovative tech, but a rather radical change in design.

Still, Boeing claims it still believes in the potential of thin-wing technology to enable efficient, sustainable air transportation. NASA’s original X-66 agreement with Boeing would see it ...

Airbus is stepping up testing of radical new wing technology as the planemaker lays the foundation for a future successor to its best-selling A320 series, but faces a battle to bring down costs.
