摘要
空间环境中飞行的尘埃粒子会对进行深空探测的航天器有重大影响,它们会撞击并沉积在航天器表面结构中,影响航天器的性能。利用空间尘埃探测器可以探测尘埃的质量、速度、飞行方向、通量、化学成分及其元素同位素、所带电荷等参数。空间尘埃探测器的基本结构设计,用软件仿真计算了撞击离子在反射式质谱计反射腔内的轨迹,验证了其探测空间尘埃的化学成分的可行性。随着深空探测的逐步深入,空间尘埃探测器探测数据将成为航天器维护及未来空间科学研究的重要参考。
The deep space exploring spacecraft can be affected by the dust particles which will impact the spacecraft and ac- cumulate in it, and this process will change the performance of the spacecraft. Space dust detector can he applied to detect the mass, velocity, trajectory, flux, chemical ingredient and isotope, and charge of the dust particle. In this paper we de- signed the main configuration of the space dust detector, simulated and calculated the ion trajectories affected by the paraboli- c grids in the reflector with software, and validated the feasibility to analyze the chemical ingredient with the reflector mass spectrograph. As the development of our country＇s deep space exploration, the data of space dust detector will he useful for protection of spacecraft and science research in the future.
