随着中国航天事业的发展,比之前更长时间更远距离的航天任务正在不断出现。这意味着,作为航天器动力装置的空间推进器,也必须做出适应性的改变。其中最为显著的,就是传统的化学推进器将部分甚至全部被电推进器所取代。传统化学推进器的困境在于,液态低温推进剂散逸速度过快,无法满足在轨时间数以年计的卫星长期储存要求,而使用常温推进剂的推进器 With the development of China’s space industry, more long-term space missions than ever before are emerging. This means that as space propellers for spacecraft power units, adaptations must also be made. The most notable of these is that some or all of the traditional chemical thrusters have been replaced by electric thrusters. The dilemma of traditional chemical propellers lies in the fact that liquid cryogenic propellants dissipate too fast to meet long-term satellite storage requirements in orbit over time, while propellers using ambient temperature propellants
