摘要
进行了固体燃料超燃冲压发动机实验研究,并成功进行了点火和燃烧实验,包括固体碳氢燃料超音速燃烧试验和聚甲基丙烯酸甲酯(PMMA)超音速燃烧试验。实验验证了固体燃料在超音速气流中能可靠点火,并保持了火焰的稳定燃烧,获得了固体燃料的超音速燃烧内弹道特性,同时研究了固体燃料PMMA在超音速气流中的燃烧,分析了其在超燃冲压燃烧室内的退移规律,认为燃料退移速度随时间变化,燃烧趋向于将燃面轮廓变平,区域显示圆柱形。
Solid fuel scramjet was investigated by experiment.Ignition and combustion experiments that include solid hydrocarbon fuel and PMMA fuel were successfully done,which proved reliable ignition of the solid fuel in supersonic flow and stable combustion of the flame.Finally supersonic chamber characteristics of solid fuel were obtained.Combustion of PMMA fuel in supersonic flow was also investigated,and its regression rule was analyzed.Results show that regression rate of PMMA fuel changes with time,combustion outline tends to be plane and combustion region exhibits column.
