=========================================================================
A new hypersonic engine developed in China could revolutionize air travel by reducing long-haul flight times to mere minutes. Capable of reaching Mach 16—approximately 20,000 km/h (12,250 mph)—this propulsion system represents a significant leap in aerospace engineering.
Developed at the Beijing Power Machinery Institute, this breakthrough has been documented in the Journal of Propulsion Technology. Researchers claim the engine is more fuel-efficient and stable than previous hypersonic designs, overcoming some of the major challenges that have long hindered this technology.
A Major Leap Beyond Supersonic Travel
For decades, supersonic aircraft like Concorde pushed the boundaries of speed, but their efficiency and fuel consumption issues limited their success. China’s latest development moves beyond Mach 2 travel, bringing hypersonic flight closer to reality.
The engine operates at 30 kilometers (18.6 miles) above Earth’s surface, using a dual-mode detonation process. At speeds up to Mach 7, it functions through a rotary detonation system, where a continuous shockwave combusts fuel more efficiently than traditional jet engines. Once it exceeds Mach 7, it shifts into oblique detonation mode, ensuring sustained high-speed performance with greater stability.
According to researchers, this approach could achieve up to 80% energy conversion efficiency, far exceeding the 20–30% efficiency of conventional engines. Addressing fuel consumption and stability challenges, this technology moves one step closer to practical hypersonic aviation.

A Revolution in Global Transportation
If successfully integrated into commercial aircraft, hypersonic propulsion could drastically reduce flight times. A journey from Paris to New York could take less than an hour, and a London-to-Sydney trip could be completed in 90 minutes instead of the usual 22 hours.
The potential extends beyond passenger travel—cargo transport at these speeds could enable near-instantaneous global deliveries, reshaping supply chains and international trade.
The ability to transport goods across vast distances in minutes would eliminate logistical bottlenecks, benefiting industries that depend on rapid shipments, such as medical supply chains and high-value manufacturing.

Military and Defense Implications
The military applications of hypersonic propulsion are equally significant. Aircraft and missiles traveling at Mach 16 would be nearly impossible to intercept with current air defense systems, raising concerns about strategic deterrence and national security.
Unlike conventional fighter jets or ballistic missiles, hypersonic vehicles move so quickly that traditional radar tracking and interception technologies may become obsolete.
China’s advancement in this field is expected to intensify competition among global superpowers. The United States, Russia, and Europe are already investing heavily in hypersonic research, but China’s breakthrough may accelerate the race for high-speed military dominance.
The ability to evade detection and strike with unprecedented speed could fundamentally change the nature of warfare, forcing nations to rethink their defense strategies.
Engineering Challenges and Future Developments
Despite its potential, significant engineering challenges must be resolved before hypersonic travel becomes a practical reality. Extreme heat and pressure at Mach 16 require advanced thermal protection systems to prevent aircraft from breaking apart.
Materials capable of withstanding these conditions must be developed, and cooling mechanisms must be perfected to ensure structural integrity during flight.
Another major hurdle is stability and control. Previous detonation engines have struggled with shockwave management, making them difficult to operate consistently. Researchers must refine the technology further to ensure that hypersonic engines remain stable across various speed ranges.
Economic feasibility is also a key concern. Although the engine is theoretically more fuel-efficient than traditional propulsion systems, developing cost-effective aircraft that can safely operate at these speeds remains a significant challenge. If the technology proves too expensive, commercial adoption could be delayed for decades.

Thank you very much and God bless you.
“How high must it travel to avert burning up due to atmospheric heat?”

Re: Google
Garbage in, garbage out.
G forces are created by acceleration.
Mach 7 is a speed, not an acceleration. “At Mach 7, the G-forces experienced by an object can be up to 9G” is a nonsensical statement to my mind.
😁...........................
I can say this much about HF.
Their moving blankets are great all purpose items. I always keep a few around.
I’ve tried to break their Pittsburgh line tools such as ratchets and I never succeeded. They would hold up as well as any of my other brand tools.
Power tools have been 50/50. I have a $30 sawzall knockoff that’s at least 10 years old that still works and won’t quit.
Quite so! It’s getting into space craft re-entry territory at those speeds.
They also steal a lot of tech.
The Concorde is coming back as early as 2026.
Yes, in two hours. But, unfortunately, it gets hungry for more fuel in an hour.
In-flight refueling might be a serious challenge.
Until I see it operation then it’s BS like everything our of China.
Next is the statement..”if successfully integrated into commercial aircraft”
No existing commercial aircraft airframe could handle a hyper-sonic engine.
We also obey the law of gravity ...
Some people never learn.
I see a lot of things coming out of China that are not introduced here at all. That indicates that China is doing a lot of innovation, but we are not.
"Overture’s order book stands at 130 aircraft, including orders and pre-orders from American Airlines, United Airlines, and Japan Airlines." 
Overture, 60-80 passengers.
Never happen at sea level.
Do they have an airframe that can survive those forces/stresses? Dinna think so.
I wouldn’t even go on an escalator built by red Chin let alone a hyper sonic jet
And it must be overhauled every 0.25 hours of operation :).
And just like Ginger Rogers did all the same dance moves as Fred Astaire, only backwards and in high heels, Eastwood had to learn to think in Russian while flying...
