Hypersonic breakthrough: Hermes quarterhorse set to shatter speed records
A hypersonic plane is a vehicle capable of achieving incredibly high speeds. The Hermeus Quarterhorse model is an innovative project to transport several people at breathtaking velocities.
Atlanta-based Hermeus is developing this pioneering aircraft, which stands out for its futuristic look and exceptional performance. What can we say about the Quarterhorse now? How does it compare to the supersonic Boom XB-1?
What is the speed of the fastest plane in the world?
The Hermeus Quarterhorse hypersonic plane is expected to be record-breaking, reaching a planned speed of 3,728 mph. It is powered by a modified Pratt & Whitney F100 turbojet engine. This advanced engine combines the features of a turbojet and a scramjet, allowing for exceptional performance.
The Hermeus Quarterhorse will be able to carry between 9 and 19 passengers. Although it is not yet known whether it will become a worthy successor to the legendary Concorde, its extraordinary capabilities are already attracting the attention of airlines and the American Pentagon. Given its specifications, this aircraft could be an ideal candidate for the new Air Force One, the plane used by the President of the United States.
When will the production of the Hermeus Quarterhorse begin?
The aircraft is currently in the testing phase, and production is planned within the next 2–3 years. Approximately five such planes are planned for production. Additionally, the American military is considering adapting a similar propulsion system for aircraft intended to transport nuclear weapons.
Why are hypersonic planes gaining popularity?
Since the retirement of the Concorde in 2003, for more than two decades, there have been no intensive efforts on hypersonic aircraft due to serious technological and economic challenges. The Concorde proved unprofitable because of high operating costs and significant fuel consumption, which made investments in similar technologies unattractive. Additionally, technological limitations like heat management, material durability at extreme speeds, and regulatory bans on flying over land due to noise discouraged further development.
However, interest in hypersonic planes is growing thanks to technological advancements and the demand for fast travel. New technologies, such as advanced computer simulations, carbon composites, and more efficient propulsion systems, allow for the creation of more economical designs. Global economic growth and private and public investments make these projects increasingly viable. Sustainable development, including sustainable aviation fuels (SAF), also supports renewed interest in hypersonic flights.
