栅极是离子推进器的关键部件之一,直接影响推进器的可靠性和寿命。由于C/C复合材料栅极具有比较小的热膨胀系数和较强的耐溅射性,可以提高离子推进器的可靠性并延长其寿命。文章通过调研综述C/C复合材料栅极的研究和应用发展状况,针对目前我国离子推进器的研究发展水平,提出开展C/C复合材料栅极研究工作的初步思路。 The gate is one of the key components of the ion thruster, directly affecting the reliability and life of the thruster. Because C / C composite gate has a relatively small coefficient of thermal expansion and strong resistance to sputtering, the reliability of the ion thruster can be increased and the life span of the ion thruster can be prolonged. This paper summarizes the research and application development of C / C composite gate by investigating and researchesing the current research level of ion thrusters in our country, and puts forward a preliminary idea of ​​C / C composite gate research.
