Chinese scientists have developed the first jet fuel-powered engine capable of Mach 16 flight, featuring combustion rates 1,000 times faster than traditional engines. By utilizing standard aviation kerosene and introducing a unique combustor design, the engine can efficiently produce thrust in extreme speed conditions. Research findings were published in the Journal of Experiments in Fluid Mechanics, highlighting its innovative functions and significant performance metrics.

Chinese scientists have achieved a significant milestone by developing the world’s first jet fuel-powered engine capable of flight at speeds reaching Mach 16. This groundbreaking technology, utilizing standard aviation kerosene, is designed to travel at velocities up to 20,000 km/h, addressing the increasing demand for high-speed aviation. The results of this research were published in the esteemed Journal of Experiments in Fluid Mechanics, highlighting the engine’s remarkable combustion rates, which are reportedly 1,000 times faster than those of conventional scramjet engines.

The engineers employed an innovative approach by strategically positioning a 5mm bump on the combustor wall, which successfully induced self-sustaining “detonation diamonds.” These ultra-fast shock wave fuel explosions enable combustion to occur in microseconds. This project, led by Han Xin from the CAS Institute of Mechanics, signifies a leap forward in engine design for hypersonic travel.

During the instrumentation tests conducted at Mach 9, the data indicated that pressure spikes at detonation points reached extraordinary levels, approximately 20 times that of ambient pressure. This finding demonstrates the engine’s potential to generate substantial thrust in speed regimes where traditional scramjet engines typically struggle to operate effectively.

In summary, the development of the jet fuel-powered engine by Chinese researchers represents a significant advancement in aerospace technology, enabling flight at unprecedented speeds. The use of innovative design features has resulted in extremely rapid combustion rates, positioning this engine as a viable option for future hypersonic travel. This achievement underscores the capabilities of modern engineering and the ongoing pursuit of advancements in flight.
