国外空间大型网状天线在轨展开故障与对策

内容简介：空间大型网状天线在轨可靠展开是确保航天任务取得成功的关键。对国外自1974—2011年间发射的部分科学、商业和军用航天器携带的大型网状天线在轨展开故障情况进行了统计，介绍了各天线展开故障的机理，并对天线展开故障应急处理方法和设计改进措施进行了总结。根据空间大型天线展开的特点，提出了加强天线抗冲击能力、充分开展天线机构实验验证和展开故障应急处理预案研究等建议。

Abstract：Reliable deployment of large spacecraft antenna is a key for the success of space mis- sion. The failures of large satellite antenna deployment in a part of scientific, commercial and mil- itary satellites from 1974 to 2011 are surveyed and analyzed. The failure causes and modes of the satellite antenna deployment are reviewed, and the emergency operations and the improvement schemes of deployment are summarized. According to the characters of the large deployable satel- lite antenna, some suggestions such as enhancing their anti-impact ability, verifying the antenna deployment through sufficient experiments and making prior researches on the recovery tech- niques are proposed to increase the deployment reliability of the large antenna.
