摘　　要：为消减液氧/煤油火箭发动机试验过程中工艺管道的多余物,消除试车隐患,基于人机环境系统理论,从人机环境综合考虑,对多余物产生的主要环节进行分析,探寻工艺管道多余物产生的根源。根据集对理论,分析影响因素间的同一度、对立度、波动度,探讨人机环境因素间耦合关系,确定多余物产生的关键因素。针对多余物的人机环境关键因素,结合实际工作,制定液体火箭发动机试验过程的多余物控制及检查方法,有效减少或消除发动机试验过程多余物的产生,保证发动机试验过程顺利安全进行。On the basis of man-machine-environment system theory, the main links to result in foreign object debris are analyzed in the aspect of man-machine-environment influencing factors to search the root of producing the foreign object debris in the process pipes for removing the foreign object debris in the pipes and eliminating the potential danger in the process of liquid oxygen-kerosene rocket engine test. The identity, opposing degree, fluctuating degree of influencing factors are analyzed by means of set pair theory to research the coupling relationship among the influencing factors, and determinate the key factors of resulting in the foreign object debris. The foreign object debris control and inspecting methods were established in accordance with the man-machine-environment key factors and practical work in the testing process of liquid oxygen-kerosene rocket engine, so that the foreign object debris in the pipes were effectively removed or decreased.
