Chinese researchers are testing a new type of ramjet engine that will allow the plane to reach anywhere in the world in just 2 hours.
According to scientists, the development can theoretically accelerate 16 times faster than the speed of sound. The existing prototype is currently being tested in a Mach 9 hypersonic wind tunnel, as the only suitable Mach 16 simulation is still under construction. During tests, it demonstrated high traction, fuel efficiency and stability of operation..
Created at the Institute of Mechanics of the Chinese Academy of Sciences, the ramjet engine with oblique direct detonation has no moving elements and consists of only three main elements: a single-stage air intake, a hydrogen fuel injector, and a combustion chamber that opens to the upper end of the air intake. Outwardly, the design is so simple that it looks a bit like a slide from a playground, but it can revolutionize commercial air travel..
When high-speed wind strikes the inlet, hot, high-pressure shock waves are generated. Colliding with hydrogen fuel in the combustion chamber, they cause its explosion, creating jet thrust.
According to the team of scientists, the idea of the engine they created belongs to the American engineer Richard Morrison, who described it back in 1980. The US government was not interested in the development, but Chinese researchers found that the gas engine outperformed all existing scramjet engines in almost every way. Previously, these experiments were classified due to their potential for military use..
The prototype engine is still experimental, so it will take at least ten years before it can be used in commercial aircraft..
Earlier, the engineers of the Celestial Empire also presented another hypersonic engine to bypass advanced missile defense systems..
