Research on the characteristic of discharge loss for ion thruster
摘要
Abstract
To clarify the mechanism of energy distribution in the process of discharge loss in ion thruster, the characteristic of discharge loss was studied. Based on the classical plasma theory, the production and movements of plasma were analyzed, and the expressions of each energy loss were obtained. Furthermore, the ratio of discharge loss was calculated in steady-state operation of ion thruster. The results indicate that ionization energy loss is 17%, excitation energy loss is 18%, electron energy loss is 25%, ion en-ergy loss makes up 35%;and the relation of discharge loss and mass utilization efficiency is calculated and validated. The results indicate the maximum error is no more than 3%.关键词
