That's Not A Knife

DART AE, produced by Hypersonix, is a three-metre-long, single-use, high-temperature alloy, hydrogen-fuelled, scramjet technology demonstrator. DART AE (Additive Engineering) makes significant use of 3D printing and is powered by a single patented 3D printed SPARTAN scramjet engine. The HASTE rocket will safely bring DART AE to its initial operating speed, allowing DART AE to demonstrate its non-ballistic flight patterns, acceleration, flexible engine burns, and up to 1000 km range, and collect valuable flight data from its journey at hypersonic speed.
