Australia gives US hypersonics a much-needed boost

As the US struggles to field its own hypersonic weapons, Hypersonix, a small Australian civilian company, might provide the much-needed hypersonic engine technology to help the US to develop the weapons. 

The Hypersonix scramjet engine was introduced to senior US officials last month and appears to have several advantages over more complex US systems. Notably, the company claims it can 3D-print a hypersonic engine in three weeks.

Hypersonix’s engine can be 3D-printed using special alloys characterized by resistance to corrosion, oxidation, high pressure and high temperature. In addition, more exotic coatings are planned to be used for exposed hypersonic vehicle flight control surfaces, which endure extreme temperatures during hypersonic flight.
