The special environment of a spacecraft with electric propulsion and its effects

摘要: 文章介紹了應(yīng)用離子和霍耳電推進(jìn)系統(tǒng)在航天器周圍產(chǎn)生的等離子體和電磁場等特殊環(huán)境，討論了這些特殊環(huán)境對航天器各分系統(tǒng)或部件產(chǎn)生的濺射腐蝕、沉積污染、充放電、等離子體干擾、碰撞動力學(xué)擾動等影響效應(yīng)，探討了研究電推進(jìn)與航天器相互作用效應(yīng)的地面試驗(yàn)技術(shù)、空間飛行試驗(yàn)技術(shù)和模型分析技術(shù)，介紹了離子電推進(jìn)系統(tǒng)與航天器相容性分析評價(jià)的技術(shù)要點(diǎn)。

Abstract: This paper discusses the special environment of plasma and electromagnetic field around a spacecraft, which is resulted from ion or Hall electric propulsion, and its effects on spacecraft subsystems or parts, including sputtering erosion, deposition contamination, charge and discharge, plasma interference and impacting dynamic disturbance. Ground and space test methods, together with model analysis methods related with the interactions between electric propulsion systems and spacecrafts are reviewed. An approach for compatibility analysis between ion electric propulsion and spacecrafts is specially addressed.
