On December 16th, it was learned from the 502 Institute of China Aerospace Science and Technology Corporation that the magnetic focusing Hall electric propulsion system developed by the institute completed all on-orbit flight verification work on the 17th satellite, which is the first in the world. A set of magnetic focusing Hall electric propulsion systems that complete on-orbit flight verification. The orbital transfer and position retention of spacecraft is mostly applied to chemical propulsion systems. The type and carrying capacity of chemical propellants limits the performance, life and flight speed of spacecraft. Since the 1960s, higher performance electric propulsion technology has become a hot spot in international research. At present, the future space missions announced by various countries indicate that more electric thrusters will be used in the main propulsion system of space probes, providing a constant source of power for spacecraft. The performance index of the aerospace propulsion system is mainly reflected in the specific impulse. The larger the specific impulse, the higher the propulsion technology performance. This time, China's on-orbit verification electric propulsion system is the second-generation magnetic focusing Hall propulsion technology, which has high thrust density, simple structure and high reliability. Through on-track performance calibration, single 8-hour continuous ignition, 20 on-off test, 50-hour on-orbit ignition and other conditions, the product is nearly 20% higher than the international power Hall thruster. The index reached the highest level of this type of thruster, marking China's ability to independently develop the second generation of higher performance Hall electric propulsion system. It is understood that compared with the chemical propulsion system widely used in China, the magnetic focusing Hall electric propulsion technology is more than 6 times higher than the impulse. For the same aerospace mission, the propellant consumed by electric propulsion is about 1/6 of the chemical propulsion. Even less. In the future, after the use of magnetic focusing Hall electric propulsion technology in China's new high-altitude satellite platform and deep space exploration mission, the weight of the propellant carried by the spacecraft will be reduced from several tons to hundreds of kilograms, which can significantly enhance the spacecraft payload and extend it. Spacecraft orbital life and reduce spacecraft launch costs.
