Thermal Characteristics Analysis and Verification of Primary Supporting Structure for Spaceborne Camera Based on Low Volume SiC/Al Primary Mirror Frame
Based on the weight constraint of micro-satellite platform on high resolution camera, taking the digital super-resolution camera of high-resolution micro-nano satellite (CX6-02) as an example, the integrated camera topology optimization design and experimental verification are carried out with primary mirror frame is taken as the primary supporting structure. The Zernike polynomial calculation and opto-mechanical thermal integration simulation are carried out, the results show that the low-volume SiC/Al primary mirror frame is effective as the supporting structure of the spaceborne camera. The thermo-optic data and on-orbit imaging results show that the experimental data of the spaceborne camera with the main supporting function of the low-volume SiC/Al primary mirror frame is consistent with the simulation data, and the performance is stable. It can provide a reference for the lightweight design and development of spaceborne cameras based on low-volume SiC/Al in the future.
