Abstract
The Large heat dissipation of LIPS-300 ion thruster seriously affects its performance.Therefore, the thermal design and analysis of LIPS-300 ion thruster in geosynchronous orbit were carried out. The simulation results show that under the high-temperature working condition,the downstream harness,downstream and upstream anode, screen grid,and downstream magnet are the positions with the highest temperature,and the temperature of the downstream magnet exceeds the temperature upper limit. In order to decrease the temperature of the downstream magnet,two optimization design measures were presented and tried. The analysis results indicate that increasing heat radiation area is an effective optimization design measure while enhancing the inner heat exchange is noneffective.关键词
