摘要
为了强化补燃室的掺混燃烧,提高发动机的性能,采用数值仿真和直连试验相结合的方法研究了掺混装置对发动机性能的影响。研究表明采用掺混装置后发动机的性能大幅提升,典型工作状态下,补燃室总压和特征速度提高约8%,发动机名义推力提高约19%。
In order to enhance the combustion performance of solid rocket-ramjet,numerical simulation(CFD) and connected-pipe experiment were carried out to study the effect of mixing device on the combustion performance in afterburner.The results show that the mixing-enhanced device can effectively improve the combustion performance in afterburner.Under the typical condition,the total pressure and characteristic velocity in afterburner would be raised by 8% by using the mixing device and the nominal thrust of the motor would be raised by 19%.
