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.

The wings of SUGAR Volt would enable it to take off in a shorter distance and generate less noise. The outer wings of the SUGAR Volt should fold to save ground space, increasing weight. Transonic truss-braced wing
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 wings are longer than the ones on previous versions of that airplane—a design change that helps increase the craft’s overall fuel efficiency. NASA’s weird wing design could lead to ...
The ecoDemonstrator Program is a Boeing flight test research program, which has used a series of specially modified aircraft to develop and test aviation technologies designed to improve fuel economy and reduce the noise and ecological footprint of airliners.

Transonic (or transsonic) flow is air flowing around an object at a speed that generates regions of both subsonic and supersonic airflow around that object. [1] The exact range of speeds depends on the object's critical Mach number, but transonic flow is seen at flight speeds close to the speed of sound (343 m/s at sea level), typically between Mach 0.8 and 1.2.
