对具有四个旁侧进气道带机械火焰稳定装置的整体式冲压喷气发动机的起动点火性能进行了试验研究,分析了点火能量、稳定器槽宽、来流温度、点火余气系数等因素对冲压燃烧室的点火延迟时间的影响。研究表明,点火能量是影响冲压燃烧室点火起动的重要因素,通过提高点火能量可以实现冲压发动机的快速点火起动;另外,稳定系数越高,点火余气系数对应的燃烧效率越高,发动机点火越容易。
The ignition performance of integral ramjet with four side inlet with mechanical flame stabilizing device was studied. The effects of ignition energy, stabilizer slot width, incoming flow temperature, ignition residual gas coefficient and other factors Influence of ignition delay time of stamped combustion chamber. The research shows that the ignition energy is an important factor that affects the ignition start of the ramjet combustion chamber. By increasing the ignition energy, the rapid ignition start of the ramjet engine can be realized. In addition, the higher the stability coefficient, the higher the combustion efficiency corresponding to the ignition residual gas coefficient. easy.
