| 摘 要： | 论述了缩比模拟发动机中大后翼与主流的相互作用以及大后翼点火的工作状态。通过试验,得出了主流和大后翼相互作用时,缝底部产生的压强较翼缝外空腔高。在试验条件下,模拟后翼气流与前部气流相互作用时没有爆燃现象。

| Abstract: | By simulated testing motors, the interaction between mainstream from grain cyliderchannel and the gas flow from large,rear fin of grain during ignition pened is researched. It can bedrawn from tests that (1) the pressurization rate at the bottom of the fin slit is obviously higher thanthat in cylider channel and in the cavity outside the fin slit, (2) the pressure at the bottom of fin slitis higher than that outside the fin, (3) Deflagration is not found during ignition on the simulated testconditions. |
