The role of high-precision weapons in the world is increasing and leading foreign countries are developing high-speed, highly maneuverable and accurate weapons, in particular, hypersonic missiles.
According to news agencies, China is testing a prototype of the promising reusable hypersonic rocket Jia Geng-1, a joint development of the Aerospace Academy of Xiamen University and the Beijing Lingkong Tianxing Technology company. The appearance of the device with an air intake at the front and a nozzle at the back indicates that it is equipped with a ramjet engine. The rocket took off for about 25 km, and then one of its stages successfully landed. The weight of the rocket is 3700 kg, a diameter is 2.5 m and length is 8.7 m. So far, this missile is a research project of civil organizations for scientific and technical support for the creation of Chinese hypersonic weapons.
Last year, China successfully tested the YJ-XX hypersonic anti-ship missile with a range of about 1,000 km to combat US warships. This is a kind of analogue of the Russian Zircon rocket, which showed a speed of Mach 8 during tests and is already in service.
In addition, in 2018, China tested the Star Sky-2 hypersonic air-launched missile, similar to Russian Kinzal system, which is based on the MiG-31 interceptor. It is obvious that China is considering the option of basing a hypersonic unit on ballistic missiles, as Russia is doing in the framework of the created powerful Avangard missile system. And tests of the prototype of the promising reusable hypersonic missile Jia Geng-1 confirm these intentions.
With these tests, China plans not only to work out the mechanism for returning the first stage as a promising technology, but also to investigate a number of problems that arise during the operation of a hypersonic rocket.
Such scientific and technological problems are solved in the implementation of innovative projects in various fields of science and technology, including electronics and instrumentation, information and communication technologies. But first of all, this applies to the field of creating new materials, which is especially important for ensuring the operability of combat units at hypersonic flight speeds.
Chinese scientists are working on creating a new ultra-temperature-resistant material from a mixture of ceramics and refractory metals, which can be used for hypersonic aircraft and withstand temperatures up to 3000 degrees, which occur during friction during flight in the atmosphere at speeds of 5-20 Mach, for several hours.
Unlike technologies using traditional refractory metals and composite-carbon materials, the Chinese development is a combination of the same refractory metals, but with the addition of ceramic elements. According to the development scientists, this solution makes the material much more effective compared to Western samples and brings it to the world's leading positions.
There is no doubt that the existing problems in the creation of hypersonic weapons by highly developed countries will be solved one way or another, because the universality of their use, high accuracy of hitting targets and low vulnerability to missile defense systems elevate such weapons to the rank of means of armed struggle, the creation and implementation of which is an important task. The race of superpowers in the field of creating hypersonic weapons continues.
