日前,于去年年底发射的遥感卫星二十四号顺利通过在轨测试。在该星研制过程中,中国空间技术研究院508所与北京航空航天大学开展合作,首次采用钛合金3D打印技术完成了次镜支撑结构的优化设计和一体化成型。据了解,3D打印技术的成功应用不仅在国内航天器中尚属首次,在国际空间光学遥感器研制中也是首创。508所与北航紧密合作,成功突破了基于 Recently, remote sensing satellites launched at the end of last year successfully passed on-orbit testing on the 24th. During the research and development of this star, China Institute of Space Technology 508 cooperated with Beijing University of Aeronautics and Astronautics, and completed the optimized design and integrated molding of the secondary mirror support structure for the first time using titanium alloy 3D printing technology. It is understood that the successful application of 3D printing technology is not only the first time in the domestic spacecraft, but also the pioneer in the development of the international space optical remote sensor. 508 in close cooperation with Beihang, successful breakthrough based on
