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 ...
USAF, NASA 1959 Hypersonic, high-altitude flight First crewed hypersonic aircraft; capable of suborbital spaceflight. [25] X-15A-2: North American USAF, NASA 1964 Hypersonic, high-altitude flight Major Pete Knight flew the X-15A-2 to a Mach 6.70, making it the fastest piloted flight of the X-plane program. X-16: Bell USAF 1954
[6] 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 ...
In aeronautics, bracing comprises additional structural members which stiffen the functional airframe to give it rigidity and strength under load. Bracing may be applied both internally and externally, and may take the form of struts, which act in compression or tension as the need arises, and/or wires, which act only in tension.
