中新社西安2月3日电 (记者 张一辰)记者3日从中国航天科技集团六院(以下简称：航天科技六院)获悉，该院801所研制的50千瓦级双环嵌套式霍尔推力器成功实现点火和稳定运行，试验验证了推力器内、外环单环点火和双环同时点火能力。这是中国首款50千瓦级双环嵌套式霍尔推力器。
这款双环嵌套式霍尔推力器由中国航天科技集团六院801所研制，成功实现了点火和稳定运行。试验过程中，推力器内、外环单环点火和双环同时点火能力得到了验证。这一成果标志着中国在航天领域取得了重要突破。
据悉，霍尔推力器是一种采用电磁原理将气体加速到高速喷出，从而产生推力的装置。双环嵌套式霍尔推力器具有结构紧凑、推力大、效率高等优点，可应用于卫星、飞船等航天器的主推进系统。
此次成功点火的50千瓦级双环嵌套式霍尔推力器，是中国航天科技集团六院801所历经多年研究攻关的成果。研究人员在设计、制造、试验等环节克服了诸多难题，为我国航天事业的发展奠定了坚实基础。

Xi’an, February 3 (CNA) — A 50-kilowatt dual-loop nested Hall thruster developed by the 801 Institute of the China Aerospace Science and Technology Corporation (hereinafter referred to as “Aerospace Technology Six”) successfully achieved ignition and stable operation, verifying the ignition capabilities of single-loop and dual-loop simultaneous ignition of the thruster. This is China’s first 50-kilowatt dual-loop nested Hall thruster.
The dual-loop nested Hall thruster, developed by the 801 Institute of China Aerospace Science and Technology Group, has achieved ignition and stable operation. During the experiment, the ignition capabilities of single-loop and dual-loop simultaneous ignition of the thruster were verified. This achievement marks an important breakthrough in China’s aerospace field.
It is understood that the Hall thruster is a device that uses electromagnetic principles to accelerate gas to high speed and produce thrust. The dual-loop nested Hall thruster has the advantages of compact structure, large thrust, and high efficiency, and can be applied to the main propulsion system of satellite and spacecraft.
The successful ignition of the 50-kilowatt dual-loop nested Hall thruster developed by the 801 Institute of China Aerospace Science and Technology Group has laid a solid foundation for the development of China’s aerospace industry. Researchers overcame many difficulties in design, manufacturing, and testing to achieve this milestone.
