The Quarterhorse hypersonic aircraft in flight

Aerospace company Hermeus has won a $60 million US Air Force contract to flight test its first Mach 5 hypersonic aircraft.

The aircraft, called Quarterhorse, will validate the company's proprietary turbine-based combined cycle (TBCC) engine, based around the GE J85 turbojet engine, and is the first in a line of autonomous high-speed aircraft.

By the end of the flight test campaign, Quarterhorse aims to be the fastest reusable aircraft in the world and the first of its kind to fly a TBCC engine.

The award was made under the AFWERX Strategic Funding Increase (STRATFI) programme led by the Presidential and Executive Airlift Directorate (PE) as a follow-on to a Phase II SBIR contract. The collaboration also includes support from the Air Force Research Laboratory (AFRL).

“Small business partnership is recognized by the U.S. Air Force as an important component to driving innovation. Reducing risk in high speed transport technologies, as we are doing with this contract, provides near-term and long-term benefits to both the U.S. Air Force and the defense industrial base,” said Joshua Burger, the Vector Initiative programme manager who is spearheading the effort. “We are very excited to see Hermeus translate their demonstrated successes in engine prototyping into flight systems.”

Hermeus is taking a different approach than traditional high-speed flight test programmes. Hermeus will be leveraging autonomous and reusable systems, ruthlessly focused requirements, and a hardware-rich programme.

These three strategies allow the team to push the envelope, sometimes strategically to the point of failure in flight test, which accelerates learning while simultaneously improving the safety of flight test crew and the public.

Pushing more risk to flight allows the company to move through the engineering lifecycle quickly, reducing programmatic costs. When exploring beyond the speeds that air-breathing aircraft have flown before, learning must come through testing in the real world.

The technology Hermeus has chosen positions the company in the dual-use space for hypersonic aircraft – technologies normally used for civilian purposes but which may have military applications.

"While this partnership with the US Air Force underscores U.S. Department of Defense interest in hypersonic aircraft, when paired with Hermeus' partnership with NASA announced in February 2021, it is clear that there are both commercial and defense applications for what we're building," said Hermeus CEO and co-founder, AJ Piplica.
