Abstract空间太阳望远镜(SST)直接对日成像,其1 m口径的主反射镜(MOT)接收到的上千瓦热量将严重影响望远镜的成像质量,因此必须进行热控设计以确保SST的性能。首先讨论了SST主镜筒内的热状况,分析了对日观测时主镜筒内的热流分布情况;然后根据SST轨道参数计算望远镜的空间轨道外热流状况;在此基础上提出了相应的热控措施,并使用热分析软件Sinda/G与Nevada计算了SST主镜筒温度分布;最后计算了SST主镜相应的热变形,对主镜镜面热变形采用Zernike多项式拟合,热变形精度小于λ/40(λ=633 nm),确保SST获取0.1″~0.15″的高分辨率成像目标,验证了SST主镜筒热控设计的有效性。
