| 摘 要： | 在模拟飞行马赫数Ma=4的直连式试验设备基础上,采用固定几何双模态冲压发动机燃烧室构型,使用液体煤油作为燃料,并用火炬式点火器点火,研究不同喷注方式下的火焰稳定性。试验研究表明:在加热器来流总温、总压较低的条件下,火焰稳定较难实现;煤油喷注方式对双模态冲压发动机燃烧室内燃烧稳定性影响很大。

| Abstract: | On the basis of direct-connect scramjet test system simulating flight Mach number 4,different injection modes were compared to study the influence of flame stability on fixed geometry dual-mode scramjet combustor fueled with liquid kerosene and ignited with torch-model ignition.It is indicated that the flame is difficult to stabilize in the flow condition of lower total pressure and total temperature.It is also indicated that the flame stability in dual-mode scramjet combustor is greatly influenced by the injection mode of kerosene. |

| Keywords: | dual-mode scramjet combustor flame stability kerosene |
