If all goes to plan, the Quarterhorse passenger aircraft will be capable of flying at a staggering Mach 5 speeds, starting at 3836 mph . By comparison, NASA'sAs Hermeus' aircraft will eventually be able to fly five times the speed of sound, it will be capable of traveling from New York to London in only 90 minutes — instead of seven hours it typically takes today's commercial airliners.
In order to reach those speeds, Hermeus is developing a proprietary turbine-based combined cycle engine, based on the GE J85 turbojet engine used for a variety of high-speed aircraft including Virgin Galactic's White Knight carrier aircraftThe first Quarterhorse prototype is set to be unmanned — much in the same way that Virgin Galactic's first space plane missions were uncrewed, the earliest flight tests will not be piloted so as to eliminate the risk to human life and to allow the...
, Hermeus has already built and tested a small-scale hypersonic engine prototype and it is now working on a full-scale engine demonstrator of its TBCC engine."By the end of the flight test campaign, Quarterhorse will be the fastest reusable aircraft in the world and the first of its kind to fly a TBCC engine," Hermeus stated in its press release.
