摘　　要：以挤压式液体火箭发动机为研究对象,对发动机推进剂供应系统工作过程进行了理论分析,利用AMESim软件建立了仿真平台,计算了发动机工作过程气瓶压力。将仿真计算结果与试车数据进行对比,结果表明仿真计算结果与试车数据一致性较好,验证了仿真模型建模思路的正确性,为气瓶压力计算提供了一种方法。Taking the gas pressure-fed liquid rocket engine with high pressure vessel as a study object, the working process of propellant feed system in the engine was analyzed theoretically. An emulator was established with AMESim. With the emulator, the gas pressure in the vessel was computed while the engine was working. The calculated result was compared with the data obtained in the test. The compared results indicate that the trend curve of the calculated result can maintain consistency with the test date. It verified the correctness of the way to establish the emulator. The method can be used to calculate the gas pressure in high pressure vessel.
