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。
Dust particles flying in a space environment can have a significant impact on spacecraft engaged in deep space exploration that impact and deposit on the surface structure of the spacecraft and affect the performance of the spacecraft. The use of space dust detector can detect the dust quality, speed, direction of flight, flux, chemical composition and its elements isotopes, the charged parameters. The basic structural design of the space dust detector is used to calculate the trajectory of the impact ion in the reflection cavity of the reflection mass spectrometer by software simulation. The feasibility of detecting the chemical composition of the dust in the space is verified. With the deepening of deep space exploration, space dust detector detection data will become an important reference for spacecraft maintenance and future space science research.
