单粒子效应对飞行器的影响分析及防护技术

Single event effect analysis on the spacecraft and the technique designed in the protection

阐述了航天飞行器运行过程中面临的空间环境条件,分析了高能粒子辐射环境中的地球辐射带、银河宇宙线和太阳宇宙线对飞行器运行安全的影响;对单粒子翻转、单粒子锁定、单粒子功能中断、单粒子烧毁事件、单粒子瞬态脉冲等类型的微电子器件单粒子效应失效机理进行了分析,提出了提高飞行器抗空间单粒子效应的防护技术,为开展相关技术设计和试验提供参考。

This paper introduced the space environment conditions faced by the spacecraft when it is flying,and analyzed the effect to security of flying aircraft from earth radiation belt,Milky Way universal line and the sun universal line in the high energy particle radiation environment;we analyzed the type of single particle failure theory of the micro-electricity component parts such as single particle invert,Single particle locking,single particle functional discontinue and single particle instantaneous impulse,etc.The paper pointed the method to improve the protection technique of the spacecraft,and applied a reference for the related technical design and test carried out.
