| 摘 要： | 模拟飞行Ma =3 5的超燃冲压发动机的燃烧室进口条件 ,采用氢为先锋火焰 ,在氢氧燃烧加热脉冲风洞上 ,对超燃燃烧室煤油燃料的点火和火焰稳定进行了实验研究 ,实现了煤油的点火和火焰稳定。实验测量了燃烧室壁面压力分布 ,并拍摄了燃烧火焰紫外光图像。实验表明 ,在燃烧室进口温度较低 (小于 90 0K)的条件下 ,在超燃燃烧室中实现煤油自燃十分困难 ,采用氢为先锋火焰实现煤油的点火是较为有效的途径之一。

| Abstract: | The direct-connected supersonic combustor experiment is finished for kerosene fuel ignition in H_2/O_2 preheated impulse facility. The entrance parameter of combustor corresponds to scramjet flight Mach number 3.5. Kerosene ignition is realized by using hydrogen as pilot flame. Wall pressure distributions of combustion are measured and flame photographs of ultraviolet ray are got. Experiment indicates that it is very difficult for kerosene fuel to realize self-ignition at low entrance temperature (below 900K) in supersonic combustor. Hydrogen pilot flame is one of the efficient methods for realizing kerosene ignition. |
