Improved analytical performance estimation and preliminary design of 50 W-class RF Ion Engine

다국어 초록 (Multilingual Abstract)

A 0-D analytical model of the plasma discharge was previously developed without magnetic ring-cusp ion engine based on energy and particles balance equations for predicting RIT thruster discharge chamber performance and thruster efficiency improvement which are affected by the design process including geometry of the discharge chamber, Ion optic, RF coil and Gas inlet. The improved analytical model plays a critical role in estimating performance of UOU-RF Ion Thruster. The present model is expanded by covering the secondary electron emission from the wall and the screen grid, double ionization xenon, Clausing factor and ion confinement factor produced by the induced electromagnetic field. In sum, several factors lead to a better calculation results that are verified by experiment data. By doing so, UOU-RF Ion Thruster is expected to produce a thrust and Isp of about 5 mN and 2600s at 2 sccm and 50 w of power loss.
