| 摘 要： | 在涡扇发动机炮式启动数学模型中考虑了埋入式进气道特性以及飞行条件对启动条件的影响因素,对与埋入式进气道联合工作的某型涡扇发动机启动条件进行了理论和试验研究。研究了不同飞行马赫数和不同攻角对发动机启动可靠性的影响。通过理论计算结果与试验数据的对比表明,存在着对涡扇发动机炮式启动可靠性起决定性的条件———临界马赫数和临界攻角。提出的启动条件成功地解决了某涡扇发动机的可靠启动问题。

| Abstract: | A model of cartridge starting of turbofan engines is developed by accounting for the effect of characteristics of the embedded inlet and flying condition. The theoretic and experimental investigation has been done for seeking the reliability condition of cartridge starting of turbofan engines, which is matched with the embedded inlet. The simulation results and testing data indicate that there are a critical Mach number and a critical attack angle, either of which has a decisive influence on the reliability of cartridge starting of turbofan engines. |
