After clearing a major round of structural stress tests, Australia’s fully 3D-printed hypersonic airframe has proven it can handle the extreme forces of high-speed flight, moving it closer to its first Mach 7 test.
Developed by Hypersonix Launch Systems, the DART AE demonstrator is a single-use platform powered by the company’s Spartan hydrogen-fueled scramjet engine designed to boost thrust while reducing emissions.
Measuring 3 meters (9.8 feet) long and weighing about 300 kilograms (661 pounds), the demonstrator is capable of flying pre-planned routes autonomously within a 1,000-kilometer (621-mile) range.
Alongside its additively manufactured structure, the vehicle incorporates off-the-shelf components — a move aimed at simplifying future production and supporting rapid scaling.
The Hypersonix team has confirmed that the demonstrator’s airframe and materials can endure the extreme stresses anticipated during hypersonic flight.
“DART AE allows us to validate propulsion, materials, and control systems at speeds and temperatures that simply can’t be replicated on the ground,” said Dr. Michael Smart, Hypersonix co-founder and former NASA research scientist.
Readying for Takeoff
With structural testing complete, Hypersonix is now setting its sights on the first flight of the DART AE demonstrator, currently scheduled for late February at the Mid-Atlantic Regional Spaceport on Wallops Flight Facility in Virginia.
According to Smart, the mission will focus on evaluating reusable, hydrogen-powered hypersonic flight under real upper-atmosphere conditions, with results expected to shape future operational platforms.
Matt Hill, Hypersonix Chief Executive Officer, also said the first flight will highlight “years of engineering work” and industry collaboration.
“It brings us a meaningful step closer to operational hypersonic systems that are reusable, sustainable, and strategically relevant for Australia and for our allies,” he noted.
