Hermeus wins $1.5M from Air Force for hypersonic flight

A hypersonic Air Force One? It could happen.

Atlanta-based Hermeus Corp. is partnering with the U.S. Air Force and the Pentagon unit in charge of presidential aircraft to develop technologies for hypersonic travel — that is, flight at more than five times the speed of sound.

Hermeus has won a $1.5 million award for the effort under the terms of a contract with AFWERX, the Air Force’s innovation program. The award follows Hermeus’ successful test of a Mach 5 engine prototype in February.

Hermeus and the Air Force will conduct a rapid assessment of the company’s hypersonic concept for the Presidential and Executive Airlift Directorate’s fleet, which includes the Air Force One airplanes.

The next planes in the Air Force One fleet will be Boeing 747 jets, which are currently being modified for presidential use. Those planes are due for delivery in 2024. Presumably, hypersonic technology will be considered for the next next Air Force One.

“Leaps in capability are vital as we work to complicate the calculus of our adversaries,” Brig. Gen. Ryan Britton, program executive officier for the airlift directorate, explained in a news release.

“By leveraging commercial investment to drive new technologies into the Air Force, we are able to maximize our payback on Department of Defense investments,” Britton said. “The Presidential and Executive Airlift Directorate is proud to support Hermeus in making this game-changing capability a reality as we look to recapitalize the fleet in the future.”

Hermeus says it brought its Mach 5 concept from design to test in just nine months. The test campaign served to reduce risk for Hermeus’ turbine-based combined cycle engine architecture, and demonstrated the team’s ability to execute projects efficiently.

“Using our pre-cooler technology, we’ve taken an off-the-shelf gas turbine engine and operated it at flight speed conditions faster than the famed SR-71,” said Glenn Case, Hermeus’ chief technical officer. “In addition, we’ve pushed the ramjet mode to Mach 4-5 conditions, demonstrating full-range hypersonic air-breathing propulsion capability.”

Hermeus is one of many ventures focusing on hypersonic flight for civilian and military applications. The other players range from Boeing and Lockheed Martin to Stratolaunch and Reaction Engines.

There are a couple of connections between Hermeus and Blue Origin, Amazon CEO Jeff Bezos’ space venture. Before joining Hermeus, Case worked as a propulsion design and engineer at Blue Origin. And one of Hermeus’ advisers is Rob Meyerson, Blue Origin’s former president.

Hermeus wins funding for hypersonic aircraft

Atlanta-based Hermeus Corp. says it’s won some high-profile seed funding for its effort to develop aircraft capable of flying more than five times the speed of sound

The startup’s advisers includes Rob Meyerson, the former president of Amazon billionaire Jeff Bezos’ Blue Origin space venture in Kent, Wash. And there’s at least one more Blue Origin connection: Hermeus’ chief technology officer, Glenn Case, worked as a propulsion design and development engineer at the company for four and a half years.

Hermeus, which was founded last year, is setting its sights on earthly hypersonic flight rather than the space frontier. It’s working on the propulsion technology for aircraft capable of flying faster than 3,000 mph. That could cut flight time between New York and London from seven hours to 90 minutes.

“We’ve set out on a journey to revolutionize the global transportation infrastructure, bringing it from the equivalent of dialup into the broadband era, by radically increasing the speed of travel over long distances.” co-founder and CEO AJ Piplica said today in a news release announcing the seed round and Hermeus’ advisers.
