Dedicated to linear motor(linear motor) launch rocket technology breakthrough. The small editor was once a loyal fan of Astro Boy. He felt that he was high-tech and could do anything from heaven to earth. In particular, the jet engine at the bottom of his feet would be converted into a rocket engine in the space environment. Of course, the technology that can be easily achieved in animation needs a lot of hard work to make breakthroughs in reality. China Aerospace Science and Technology Group disclosed in the "National Defense Science and Technology Industry" article that China's future light boat electric rocket and featherboat liquid rocket will be launched by the "ground large-scale electromagnetic system" and is scheduled to complete the demonstration system construction and principle verification experiment in 2020. Electromagnetic emission or ejection is not a new technology and new concept. The principle is to use a linear motor(linear motor) to accelerate the object.
As early as the 1940s, the United States conducted related experiments. However, it was not until the recent practical application of electromagnetic ejection systems and electromagnetic guns that Ford aircraft carriers installed electromagnetic catapults and Jumwalt-class destroyers installed electromagnetic guns. The reason why the time between the test and the practical period was nearly 670-year, was because the principle of electromagnetic launch or ejection was simple, but the technology required for practical application was very complex and it was very difficult to break through.
So what technology has China achieved in the field of electromagnetic launch or catapult?
One is linear motor(linear motor) and track laying technology. The basis for realizing electromagnetic launch or ejection is the manufacture of ultra-long linear Motors(linear Motors) and launch or ejection orbits. The accuracy of the orbit is extremely high because electromagnetic launch or ejection accelerates the object to super-high speed in an instant. Failure to achieve the required accuracy in orbit laying will cause fatal disaster.
The second is material technology. Electromagnetic launch or ejection instantly accelerates the ejection object to super-high speed. The ejection object has great friction with the orbit. At the same time, the ejection object also suffers a huge impact. This requires new materials with high strength and high stiffness.
Third, magnetic shield technology. The greater the electromagnetic launch or ejection thrust, the stronger the magnetic field generated, and the resulting magnetic field is not all used to provide thrust. If it is not shielded, this will cause great damage to the surrounding environment.
Kunshan Tongmao Electronics Co., Ltd. has been focusing on the production and research and development of linear Motors(linear Motors) for ten years. The linear Motors(linear Motors) produced by the company adopt advanced European and American technical standards, processes and test methods, and their quality and power performance have reached the international advanced level., It is recognized by customers at home and abroad.
