A model of the Transonic Truss-Braced Wing aircraft in a wind tunnel at NASA's Ames Research Center. By early 2019, following extensive wind tunnel testing at NASA Ames Research Center, an optimized truss and more sweep for the 170 ft (52 m) span wing allowed flying higher and faster, up from Mach 0.70–0.75 to Mach 0.80 like current jetliners.

It’s called the Transonic Truss-Braced Wing concept, which relies on elongated, thin wings stabilized by diagonal struts that connect the wings to the aircraft. The design’s shape creates less ...

The ecoDemonstrator program was formally launched in 2011, in partnership with American Airlines and the FAA. [16] The first ecoDemonstrator aircraft, a Boeing 737-800 , operated during 2012. Since then a different aircraft has been used each year, excepting 2013 and 2017 and a single aircraft from 2022 to 2024, with testing operations lasting ...
