在直连式试车台上进行了一系列固体燃料冲压发动机燃烧室试验,其中,旋流数的变化范围是0～0.55,旋流分布有几种,所用燃料是聚乙烯和改性端羟基聚丁二烯(HTPB)。试验中测量了进气温度和质量密流对装药燃速的影响,此外,还在两个不同截面测量了温度和燃气浓度的分布。 A series of solid fuel ramjet engine combustor tests were carried out on the direct test bed, in which the swirl number varied from 0 to 0.55 with several swirl distributions. The fuel used was polyethylene and modified hydroxyl terminated poly Butadiene (HTPB). The effects of inlet air temperature and mass flow on the charge rate were measured during the experiment. In addition, the distributions of temperature and gas concentration were also measured at two different sections.
