Abstract:The refueling of large-scale non-coplanar constellation by multiple suppliers based on formation flying is studied in this In response to the current situation of outdated and single testing and launch training methods for launch vehicle, as well as the demand for equipping the launch vehicle testing and control system, breakthroughs have been made in key technologies such as rocket full-truth equivalence technology, IETM and testing and control fault injection technology. Based on a certain type of liquid carrier rocket, a practical and physical testing and launch training system has been constructed. Through training and assessment position personnel rapidly and efficiently, the technical requirements for testing and control positions have been met, having the ability to test and control launch vehicles, enabling test personnel to transition from operational to experimental engineering, accelerating talent cultivation, and improving the comprehensive testing ability and success rate of launching site.
