摘　　要：依据水击理论,以某液体火箭发动机为例,采用特征线法建立推进剂供应系统一维流动数学模型,实现了关机水击数值模拟。实例计算分析了测压导管对水击过程的影响。Taking one liquid rocket engine as example, the characteristic method is adopted to es- tablish a one-dimension mathematical model of the propellant feeding system on the basis of water-hammer pressure theory. The numerical simulation of water-hammer pressure as the engine is shut down. The effect of the manometry conduit on the water-hammer process is computed and analyzed with the example.
