摘　　要：空间推进系统必须可靠地完成轨道保持、轨道修正、姿态控制的重要任务 ,要求当其某一功能模块出现故障时、能及时发现并有效隔离。文中介绍了利用有向图方法分析此推进系统故障传播机理的方法 ,并建立相应的故障推理模型。离线检测和理论分析表明 ,此方法逻辑性强 ,简单高效 。The space propulsive system is a power system composed of various types of engines.It must be capable of working in space for a long time with very high reliability.When a fault appears,it needs to be detected in time and shut off effectively.In the paper,the authors have introduced a fault reasoning method (fault directional graph) used in space propulsive system,and a corresponding fault reasoning model has been set up.Numerical simulation and theoretical analysis show that the model is simple and effective,and it is possible to be used for space application in a real time way.
