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 ...

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.
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 ...
For aircraft of moderate engine power and speed, lift struts represent a compromise between the high drag of a fully cross-braced structure and the high weight of a fully cantilevered wing. They are common on high-wing types such as the Cessna 152 and almost universal on parasol-winged types such as the Consolidated PBY Catalina .
