Hermeus Progresses Toward Hypersonics with Engine Demo

AIN Online by Kerry Lynch - November 17, 2022

Hermeus took another step forward in its quest to bring hypersonic transportation to market, demonstrating turbojet to ramjet transition within its engine, Chimera. The Atlanta-based company called the demonstration “one of the most important technological feats to making operational hypersonic flight a reality.”

Chimera is a turbine-based combined-cycle engine that essentially is a hybrid between a turbojet and ramjet. The ability to transition between the two will enable Hermeus’s first demonstrator aircraft, Quarterhorse, to take off from a regular runway and then accelerate to high-Mach speeds, the company explained.

Chimera is designed with a pre-cooler to reduce the temperature of the air coming into the turbojet. Once the aircraft reaches Mach 3, the engine will bypass incoming air around the turbojet, enabling the ramet to take over. The company noted its design is unique because most hypersonic platforms are powered by rocket engines not suitable for passenger flight.

With the demonstration complete, Hermeus is turning its focus on the completion of Quarterhorse for its first flight in late 2023.
