Ultra-lightweight Design and Analysis of a 1.25m SiC Segmented Mirror

  In order to explore the feasibility of large ultra-lightweight deployable optical systems,a 1.25m SiC segmented mirror is investigated.According to analysis and comparison,the mirrors material,ultra-lightweight structure pattern and support location are determined respectively.By FEM,an ultra-lightweight structure with areal density of 40kg/m2 is gotten.The results show that the self-weight deformation is 4.8nm RMS/22.6nm PV under supports,and the ultra-lightweight mirror has the enough strength to bear the stress at launch.The study may provide a technical scheme to develop the large ultra-lightweight deployable optical system.
