| 摘 要： | 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。 |

| Abstract: | The experimental investigations on the ignition performance of an integrated ramjet engine with 4-side inlets were performed as well as a flame stabilization device.The influence of the ignition energy supplied,the gut width of the stabilizer,the coming flow temperature and the equivalence ratio on the ignition response time for the ramjet were studied.The results indicated that the ignition energy is an important factor for the ignition and starting of the ramjet combustor.The increase of the ignition ener... |
