真空和温度对卫星太阳电池翼板展开的影响

本文针对卫星上折页式太阳电池翼板的展开,根据国内外卫星的一些实际飞行情况与地面的模拟试验,着重分析了真空和低温对展开的影响,强调在地面做真空低温环境中展开试验、测量其展开特性的重要性。最后对展开机构提出了几点看法和建议。

EFFECTS OF VACUUM AND TEMPERATURE ENVIRONMENT ON DEPLOYMENT OF SATELLITE SOLAR WING PANEL

Concerning deployment of folded solar wing panel of satellite,this paper emphatically analyses the effects of the vacuum and low tempe-rature environment on deployment,based on some practical flight status ofsatellites and its simulating test data on ground in China and other countries,and emphasize the importance of deployment test at low temperature conditionin Vacuum on ground and measuring its deployment specific property.Fina-lly,this paper presents some views and recommendations on the deploymentmechanism.
