Abstract

Current design process for the Hall effect thruster has relied on expensive experimental method based on the limited historical data. In this study, a proper design space for the Hall effect thruster is chosen and associated design space exploration is conducted based on a recently proposed numerical method in order to improve current design process. According to the results of the design space exploration, performance envelope is determined for the given design space and the correlations between performance metrics are analyzed. Further analysis shows that main factors in performances for the Hall effect thruster are the anode mass flow rate and the discharge voltage.

기존의 홀추력기 개념 설계는 비용이 많이 소요되며 과거의 데이터에 기반한 실험적 방법에 근거하고 있다. 본 연구에서는 이러한 홀추력기의 설계 과정을 향상시키기 위해 최근 제안된 수치적 방법에 근거하여 설계 목적에 적합한 설계 공간을 설정하고 이에 대한 설계 공간 탐색을 수행하였다. 설계 공간 탐색의 결과를 통해 기본적으로 주어진 설계 공간에 대한 성능 범위를 결정하였으며 성능간의 관계를 분석하였다. 세부적인 결과 분석을 통해 홀추력기의 주요한 설계 변수로는 양극에서의 질량유량과 방전전압임을 도출하였다.
