Quarterhorse; US Air Force invests in the development of the world’s fastest supersonic aircraft

Air Force has joined a group of investment companies that are investing $ 60 million in a project of Hermes,

a Georgia-based start-up that seeks to build the world’s fastest reusable supersonic aircraft, according to a press release. Have invested.
This new investment sets ambitious goals for Hermes that must be achieved over the next three years.

This includes building three prototypes of the company’s Quarterhorse aircraft and testing its full-scale ultrasonic propulsion system.
If all goes according to plan, the Quarterhaus passenger plane will fly at a staggering Mach 5 or 6,174 kilometers per hour. By comparison, NASA’s X-59 ultrasonic aircraft, built at Lockheed Martin’s plant, will fly at Mach 1.5.

Being able to fly at five times the speed of sound can mean traveling from New York to London in just 90 minutes; At present, with commercial aircraft, the journey takes about seven hours.
To achieve such speeds, Hermes is developing a dedicated turbine-based combined cycle (TBCC) engine based on the GE J85 turbojet engine used in a variety of high-speed aircraft, including the Virgin White Knight and the Ultrasonic prototype aircraft. X-1 is a product of Boom Supersanik.
