| Abstract: | The grid is one of the key components for ion thrusters, which has direct influence to the reliability and lifetime of the ion thruster. Due to its very low heat expansion coefficient and high anti-sputtering capability, the use of C/C composite for grid may help to improve the reliability and lifetime of ion thrusters. This paper reviews the research, development and application of C/C composite grids. Some suggestions about the research and development of ion thrusters in our country are put forward. |
