摘　　要：文章针对批产化遥感卫星研制要求,探索了热控系统的优化策略,应用于“吉林一号”某批产卫星的研制过程。相较单星侧重于目标可行性验证的研制流程,批产卫星的研制重点为更低成本、更高效率的生产。文章遵循结构-热控一体化的思路,进行了低外热流敏感性、低控温功耗、低材料成本的热控设计;依托脉动式AIT生产线及自动化生产设备,细化热控实施流程,缩短准备工作时长,灵活安排人员工位,大幅提升卫星生产效率;依据批产卫星的热控设计特点及试验需求,采用基于等效热沉的外热流模拟方法,降低了真空热试验的复杂性。当前该型号批产遥感卫星已生产并发射54颗,卫星在轨状态良好,该热控批产化研制思路可为其他批产卫星的研制提供有效参考。In response to the requirements for the development of mass production remote sensing satellites,an optimization strategy for the thermal control system was explored and applied to the development process of a certain batch of Jilin-1 satellites.Compared to the development process of single satellites,which focuses on target feasibility verification,the focus of mass production satellite development is on lower cost and more efficient production.The article follows the idea of integrating structure and thermal control,and conducts thermal control design with low external heat flux sensitivity,low temperature control power consumption,and low material cost;Relying on pulsating AIT production lines and automated production equipment,the thermal control implementation process is refined,thus shortening the preparation time,flexibly arranging personnel workstations,and significantly improving satellite production efficiency;Based on the thermal control design characteristics and experimental requirements of mass-produced satellites,an external heat flow simulation method based on equivalent heat sink is adopted to reduce the complexity of vacuum thermal testing.Currently,54 satellites of this model have been produced and launched,and the satellites are good in orbit.This thermal control batch production development concept can provide an effective reference for the development of other batch production satellites.
