国外航天AIT厂房天车污染物防护技术措施跟踪研究

Protection against contamination from cranes for foreign space AIT workshop

航天AIT厂房的天车在使用过程中经常会出现机械摩擦产生的金属粉末和润滑油滴落等污染物,可能对AIT厂房和航天器造成污染。文章通过对国外航天AIT厂房天车污染物防护技术措施的跟踪研究和分析,为解决国内航天AIT厂房天车污染物防护问题提供借鉴。

In space AIT workshop,the crane often generates some contamination such as metal powder from machine friction,lube dropping,and solid residue and so on.Thus,the airborne particulate cleanness class is reduced and the spacecraft may be contaminated.This paper traces and analyzes the protection measures against contamination from cranes in AIT workshop.
