A five-year-old startup has developed one of the most powerful aircraft engines.
, enabling the aircraft to take off, accelerate, and reach high speeds. As the speed and temperature of air coming towards Quarterhorse increases, the Chimera engine begins transitioning from a turbojet into a ramjet.
This process begins around Mach 2 speed and completes at Mach 3 when the engine starts drawing in air at supersonic speeds. This air is fast enough to achieve combustion without a compressor. This is where the turbojet engine becomes inactive, and the ramjet engine gets into the action, boosting the aircraft's speed and allowing it to fly at its highest speed.
“Chimera has a pre-cooler that reduces the temperature of the air coming into the turbojet. This allows Hermeus to squeeze out a bit more performance from the turbojet before transitioning to ramjet. At around Mach 3, Chimera begins to bypass the incoming air around the turbojet and the ramjet takes over completely,”The Chimera engine is special because it could make hypersonic passenger flights a reality.
The company received funding in 2021 only, and the team is excited about what it has achieved only in the past few years with the Chimera engine. They have also secured contracts from NASA and US Air Force. Apart from the Quarterhorse project, Hermeus is working on technologies to improve high-speed uncrewed flight applications. Hopefully, we’d soon be able to witness Quarterhorse’s hypersonic performance in the open sky.
