Friends who have seen American Hollywood sci-fi blockbusters are sure to be shocked by the super sci-fi engine of the spacecraft in the US interstellar voyage. In fact, this engine has been developed. This type of engine is a so-called electric propulsion engine. At present, China has made breakthroughs in this field and will soon be put into practical use. The pace of China's catch-up has already been side by side with the United States and Europe.
According to media reports, China has initially mastered the full-powered satellite control capability, and it is likely that engineering development of such satellites will begin soon. According to a report published in the China Aerospace News, after two years of scientific research, the integrated design of the 502 electric propulsion platform control system of the China Aerospace Science and Technology Corporation has been released. This indicates that China has initially mastered the design method of electric propulsion satellite GNC (Guidance, Navigation and Control) system.
In recent years, China has continued to exert its strength in the development of satellite electric propulsion engines, and the situation of backwardness in the early years has been greatly improved. According to reports from the media at the beginning of last year, China's Hall electric propulsion technology has made a major breakthrough--the long-life test of the hollow cathode of the 80mN Hall thruster broke through 18,000 hours, accumulated 15,000 times, far exceeding 7500 hours, and the cumulative ignition is 8000 times. Mission indicator requirements. You can ignore all the above data. Let's look at the following. The breakthrough of this technology will lay a solid foundation for the new era of China's electric propulsion system to enter full application.
If you still don't understand the above sentence, it doesn't matter, please continue to look down. The principle of electric propulsion engine is to use electromagnetic field to accelerate the plasma working medium to produce reaction force. That is to say, this kind of engine will be great. Save the spacecraft's fuel, such as satellites, to increase the satellite's own load.
