【摘要】 以采用强迫起动方式的补燃发动机涡轮泵联试系统为研究对象,建立了系统的动态模型。对联试装置进行了综合冷调试验并对联试的起动过程进行了数值模拟。结合综合冷调试验结果和数值仿真结果,制定了系统的起动程序。试车结果表明联试系统起动过程平稳。对计算结果和试验结果进行了对比,二者吻合的较好。更多还原

【Abstract】 The dynamic model is established for a turbo-pump test system of a staged combustion cycle engine which employs forced start. A synthetical cold-flow test was carried out with the turbo-pump test system, and the start-up process of turbo-pump test system was simulated. Based on the synthetical cold-flow test results and simulation results, the start-up procedure of the test system was given. The test results show that the start-up process of turbo-pump test system was smooth. The simulation results fit well with test data.更多还原
