摘要:
随着空间探测任务的多样化和复杂化,利用单个航天器的多舱段实现多任务、多目标探测已成为航天技术的发展趋势。通常情况下,舱段分离信号将触发航天器的后续自主控制,直接影响航天器的自身安全和后续任务执行。本文从保证分离信号可靠和分离过程安全的角度提出了一种典型的分离信号配置与通用的分离信号触发控制逻辑,并建立了航天器在轨分离安全性数学模型。该模型和逻辑控制方法经过仿真分析和实际在轨飞行任务验证,确认了方法的可行性和正确性,可以作为后续航天任务的参考。

Abstract:
With the diversity and complexity of space exploration missions,the multi-mission and multi-target exploration with single spacecraft of multiple modules is the development trend of space technology. Under normal conditions,the separation signals trigger the continuous autonomous control,which influences the safety of spacecraft and follow-up missions. In this paper,a typical separation signal configuration and a common logical control method based on the trigger of separation signal are proposed aiming at guaranteeing the reliability of separation signal and safety of separation. A mathematical model is set up for on-orbit separation of spacecraft modules as well. Both the model and control method have been simulated,analyzed and tested with practical flight missions. The feasibility and validity of this method are demonstrated for the follow-up flight missions.
