Hermeus F100 Engine Testing [4K]

Hermeus has begun testing our proprietary precooler technology with the Pratt & Whitney F100 engine. This video highlights some of our favorite camera angles from testing.

What's a precooler and why are we testing it? The Hermeus precooler increases the max speed of the turbine engine by lowering the temperature of incoming air. This is the first major propulsion milestone for our next aircraft, Quarterhorse Mk 2, which will utilize this engine configuration and fly at supersonic speeds.

The precooler is part of our larger turbine-based combined cycle (TBCC) engine. Our TBCC engine, named Chimera, is a full-range, air-breathing hypersonic engine combining a turbine with a ramjet. At low speeds Chimera operates in turbine mode with the F100 engine, while at higher speeds the engine transitions to ramjet mode. The precooler helps bridge the gap between these two modes of operations by increasing the performance of the turbine.
