The Brisbane startup that flew a 3D printed jet engine at five times the speed of sound

A Brisbane team built a scramjet with no moving parts that burns hydrogen, and has now flown its first hypersonic aircraft.

Almost no one in Australia has heard of Hypersonix. They should have.

The engine

A former NASA scientist built a scramjet: a jet engine with no moving parts at all. It burns hydrogen instead of kerosene, so it puts out zero carbon dioxide. And it is fully 3D printed.

The flight

Hypersonix strapped its 3.5 metre DART AE aircraft to a rocket, launched it out of Virginia with the US Defense Innovation Unit, and released it in the upper atmosphere to fly its hypersonic mission. It was the company’s first flight, and a milestone for Australian built hypersonics.

The mission was officially called That’s Not A Knife.

The money

  • US$46M raised
  • Backed by the federal government’s National Reconstruction Fund
  • The engine is designed to reach Mach 12

My read

A team of around 50 people in Brisbane just did what most countries cannot. Hypersonic flight is one of the most strategically important technologies in the world right now, and Australia has a company that has actually flown it.
