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 RS1 launch vehicle first flew on Jan 10, 2023. The launch ended in failure. [78] — X-64 Invocon Inc.

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 ...
The Boeing Truss-Braced Wing subsonic concept was planned with hybrid electric propulsion. [1] The Diamond DA36 E-Star first flew on 8 June 2011, the first flight of a series hybrid powertrain, reducing fuel consumption and emissions by up to 25%, a technology scalable to a 100-seater airliner. [2]

Aurora is refining the fuel-efficient D8 designed for NASA by MIT, and originally hoped to fly a half-scale demonstrator in 2022. [4] The 180-seat, 3,000-nautical-mile-range (5,600 km; 3,500 mi) airliner is designed to fly at 582 mph (937 km/h; 506 kn) within the capabilities of the Boeing 737 or Airbus A320 and could be in test service by 2027 ...
