【摘要】：20cm離子推力器在SJ-9A新技術(shù)試驗(yàn)衛(wèi)星上的飛行試驗(yàn)已經(jīng)結(jié)束,為了檢驗(yàn)飛行試驗(yàn)的有效性,十分有必要對(duì)離子推力器在軌工作性能進(jìn)行全面分析評(píng)價(jià),以便為后續(xù)空間應(yīng)用提供依據(jù)。利用在軌獲得的試驗(yàn)數(shù)據(jù)對(duì)離子推力器主要工作參數(shù)進(jìn)行了分析,并通過與地面試驗(yàn)數(shù)據(jù)進(jìn)行對(duì)比,系統(tǒng)性的評(píng)價(jià)了其工作性能。評(píng)價(jià)結(jié)果表明,在整個(gè)飛行試驗(yàn)期間離子推力器各項(xiàng)工作性能參數(shù)符合設(shè)計(jì)指標(biāo)要求,其中推力在38~39.2m N,比沖在2900~3200s,功耗小于設(shè)計(jì)值1080W。飛行數(shù)據(jù)與地面試驗(yàn)數(shù)據(jù)吻合很好。
[Abstract]:The flight test of 20cm ion thruster on SJ-9A new technology test satellite has been completed. In order to test the effectiveness of flight test, it is necessary to analyze and evaluate the in-orbit performance of ion thruster in order to provide the basis for subsequent space applications. The main working parameters of the ion thruster are analyzed by using the test data obtained in orbit, and the working performance of the ion thruster is systematically evaluated by comparing it with the ground test data. The evaluation results show that the working performance parameters of the ion thruster meet the design requirements during the whole flight test, in which the thrust is 38 鈮，
