Air-breathing systems for supersonic and hypersonic platforms edge closer to flight as scaled ground demonstrators and rig tests progress

The facilities will support testing of the Atlanta-based company’s Quarterhorse and Darkhorse series of high-speed testbeds.

The hypersonic aircraft developer has completed low-speed taxi tests of its Quarterhorse Mk. 1 vehicle ahead of flight tests planned for later this year.

The location emerged in local news reports in Jacksonville about a $135 million economic development opportunity involving 100 jobs.

Hypersonic startup accelerates development plan with jump to revised Quarterhorse demonstrator strategy.

The latest tests of the larger-scale pre-cooler are underway at Edwards AFB, California.

Hypersonic aircraft developer Hermeus has unveiled its first flying test vehicle—Quarterhorse Mk. 1—at its Atlanta facility.

The startup details the Quarterhorse flight-test plan as concept design work accelerates for the follow-on Darkhorse hypersonic cruiser.

Under HyCAT, Hermeus says it will use its high-Mach-capable Quarterhorse vehicle to demonstrate key "enabling technologies for operational hypersonic aircraft."

The Quarterhorse Mk 0 is a less than 40-ft.-long mockup featuring the turbine-based combined cycle (TBCC) Chimera 1 engine.

Aircraft startup Hermeus received the first military turbofan that will be integrated into the engine core for the hypersonic Darkhorse uncrewed aerial system.

Hypersonic aircraft developer Hermeus expects to receive Pratt & Whitney’s F100-229 military turbofan for tests later this year.
