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 ...
Proved aerodynamic viability of thin wing sections.

In 2018 a new design of engine inlet liner was flight tested in a successor program, Quiet Technology Demonstrator 3 (QTD3), using acoustic arrays at Moses Lake, Washington. [13] The NASA-designed inlet was installed in the right-hand nacelle of one of Boeing's two 737 MAX 7 prototypes, [14] powered by CFM International LEAP 1B engines. The ...

Boeing’s Mach 0.78 Truss-Braced wing concept High-speed wind-tunnel testing is planned for fiscal 2019. The Airspace Operations and Safety Program ($91 million in 2019) includes ATM-X to support urban air mobility in national airspace: automated trajectory negotiation and management flights are planned for January 2019, followed by dynamic ...
The X-53 Active Aeroelastic Wing (AAW) development program is a completed American research project that was undertaken jointly by the Air Force Research Laboratory (AFRL), Boeing Phantom Works and NASA's Dryden Flight Research Center, where the technology was flight tested on a modified McDonnell Douglas F/A-18 Hornet.
