摘要: 随着空间技术的发展,卫星热控系统面临着巨大的设计挑战.首先,根据快速响应空间小卫星的新特点,分析比较了其热控设计与传统设计方法的区别,从而提出了快速响应空间小卫星热控系统的研制流程.然后针对实现快速响应空间小卫星热控系统设计的关键步骤:多轨道极端工况外热流参数的确定、模块化热构架系统和热控系统快速分析技术进行了详细的阐述和介绍.最后,追踪了实现快速响应空间小卫星热控系统研制的新型热控器件的研究和应用.作者认为,时间驱动的热设计理念,稳健、模块、可扩展的热设计方法,以及新型先进智能热控器件的研制是由快速响应空间小卫星的任务特点所决定的必然要求和实现途径.Abstract: With the development of space technology, satellite thermal control systems face new challenges. First, a detailed comparison of traditional and responsive thermal control systems was presented according to the characters of small speedy responsive space satellites, and then a new design process was derived for responsive thermal control systems. Each of the key technologies including a single hot and cold case design orbits, modular thermal architectures, fast analysis and virtual test method was introduced. Finally, the advanced equipment and materials for responsive thermal control were reviewed. In a word, the author considers that a robust modular scalable thermal control with new advanced smart thermal control device was the certain requirement and way to implement responsive thermal control systems.
