詹姆斯·韦布空间望远镜试验验证方法述评

Review of test verification approaches for James Webb Space Telescope

  • 摘要: 詹姆斯·韦布空间望远镜(JWST)是目前世界上最大的空间望远镜,也是继哈勃空间望远镜之后的又一旗舰级望远镜任务,该望远镜装备有须在深低温环境下运行的大尺寸和高精度光学器件,常规试验方法及设备不能满足其研制需求。为平衡研制周期、研制成本以及任务整体可靠性,JWST采用了不同于传统航天器的试验验证方法,即集成模型仿真验证与试验验证相结合的方法。文章对JWST的分系统级、系统级试验验证方法进行调研分析,并简述其地面试验系统设备的改造情况,以期为我国未来大型航天器试验技术的发展提供参考。

     

    Abstract: As another flagship telescope mission after the Hubble Space Telescope, the James Webb Space Telescope (JWST) is currently the largest space telescope in the world. The JWST is equipped with large-sized and high-precision optical devices that must be operated in a deep cryogenic environment. However, the traditional test approaches and equipment cannot meet its development needs. To balance the mission development cycle, cost, and overall reliability, the mission JWST has adopted a different test verification method from those of traditional spacecraft, which has combined integrated model simulation verification with test verification. In this paper, survey and analysis on the subsystem level and system level test verification methods of the JWST in addition to the description to the modification of its ground test system equipment, were reviewed. The review may provide a reference for the development of future large-scale satellite testing technology in China.
