| Abstract: | Ion electric propulsion (IEP) is one of the most representative and mature electric propulsion technologies. In this paper, the development status of IEP is summarized from the aspects such as discharge chamber technology, ion optics system, hollow cathode, and neutralizer cathode. In order to meet the requirements, e.g., larger power, higher specific impulse, and simpler system, for the IEP in future space missions, the main technical challenges of conventional IEP are analyzed. It is suggested that traditional IEP will develop towards the innovative IEP such as annular-geometry IEP, dual-stage accelerated IEP, self-neutralizing IEP, and helicon wave discharge IEP. |
