Today, let's talk about a topic that has attracted global attention - China's latest breakthrough in aviation technology. Imagine a stopover from Beijing to Guangzhou, or a trip around the world in a short afternoon, which is no longer a fantasy of science fiction, but a real possibility given to us by technology. The standing oblique detonation ramjet engine developed by Chinese researchers not only broke the American record, but also left it far behind, running for up to 600 seconds, which is a milestone in the history of science and technology. This engine has shown unprecedented outstanding performance in terms of thrust, fuel efficiency and working stability, marking China's leap to the forefront of the world in the field of scramjet engines.

To understand this technological innovation, it is important to recognize that the engine is an artifact that converts various energies into mechanical energy. Jet engines and turbofan engines propelled aircraft into the sky with high-velocity airflow or the synergy of gas and fan exhaust. The standing oblique detonation ramjet engine shows a new era of supersonic flight in a revolutionary way. In a hypersonic wind tunnel, the performance of this engine is amazing. Its uniqueness lies in the fact that it uses the oblique detonation combustion method to convert the supersonic shock wave into the power source of the engine, eliminating the negative impact of the shock wave, and turning it into a powerful tool to promote the efficient combustion of fuel. With no complex moving parts, consisting of a monopole, air intake, light fuel injector and combustion chamber, its dustpan design is not only aesthetically pleasing, but also extremely efficient in practice.

When the high-speed air flow meets the hydrogen fuel in the combustion chamber, the detonation wave point fuel material is instantly generated, releasing a huge amount of energy, which ensures the stable operation of the engine and produces amazing thrust. In contrast, the X51A demonstrator in the United States tried to break through Mach 5, but was limited by combustion efficiency and stability problems, and failed to continue to operate for more than 300 seconds.

The success of China's standing oblique detonation ramjet engine not only solved the above problems, but also opened a new chapter in the aviation industry. If applied to the DF-17 missile, its range is expected to reach the intercontinental level, posing a serious challenge to the existing defense system. Behind this achievement is the support of the JF12 wind tunnel, which is an important scientific research tool. As the world's largest shock wave wind tunnel, it is capable of simulating a wide range of flight conditions, providing critical data for aircraft design and testing, and enabling a leap forward in scramjet technology.
