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 ...
First aircraft to exceed Mach 3. [11] X-3 Stiletto: Douglas: USAF, NACA 1952 Highly loaded trapezoidal wing: Titanium alloy construction; Underpowered, but provided insights into inertia coupling. [12] X-4 Bantam: Northrop: USAF, NACA 1948 Transonic tailless aircraft [13] X-5: Bell USAF, NACA 1951 variable geometry: First aircraft to fly with ...
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]
Bell X-2 – Mach 2–3 supersonic flight; Douglas X-3 Stiletto – Sustained supersonic flight; Northrop X-4 Bantam – Tailless aircraft; Bell X-5 – Variable-sweep wing; Convair X-6 – Nuclear reactor test aircraft (for nuclear-powered aircraft) Lockheed X-7 – Unmanned ramjet and guidance test missile; Aerojet General X-8 – Sounding ...
