Recommended reading: the last battle in China, the Vietnamese description surprised me. look at the details and search the WeChat public number: sinamilnewsAfter an experiment with a hypersonic wind tunnel, many Indian projects have been carried out at the same time in hypersonic weapons. In particular, the engine part of a high supersonic missile. In 2016, India successfully carried out a 5 minute scramjet flight test. In the test, the scramjet runs normally and reaches the maximum speed of 6MA. In the near future, India media has revealed that India's scramjet has overcome the related technical difficulties and has been able to produce hypersonic weapons with long-range strike capability.Taking the example of a -3 supersonic anti ship missile, the missile is equipped with a solid rocket engine plus a subcombustible ramjet. The rocket engine is detached after the solid rocket engine provides enough speed and is pushed forward at high speed by the ramjet. As a result of the use of a ramjet, the maximum speed of -3 is only 2.5MA.Scramjet, because air does not need to decelerate to enter the engine, has a considerable test on the fuel mixing ability and pressure capacity of the engine. But the maximum speed of the scramjet can be even more than 8MA, and both China and the United States and Europe have a little development. In contrast, Russia's super combustion engine has developed slowly, even in the wind tunnel testing stage, which makes it very exciting.
