| 摘 要： | 对Helmholtz型脉动发动机的主体结构燃烧室-喷管进行了研究,分析了5 种燃烧室柱部直径的发动机所构成的声学条件,以及3种油门开度所构成的加热条件对发动机工作频率的影响。结果表明,在燃烧室柱部直径变化范围内,声学条件对发动机工作频率的影响不大,加热条件则显著改变发动机的工作频率。

| Abstract: | The combustion chamber and tailpipe is a main part of Helmholtz type pulse-jet engine. How both the acoustics condition formed by structure parameters of five kinds combustion chamber and tailpipes and calefaction condition constituted by three kinds fuel restrictor opening affect the work frequency of pulse engines had been studied.The conclusion is that the calefaction condition intensively works on the work frequency of a pulse-jet engine in the change range of the diameter of the cylindric part of the combustion chamber in the paper,on which the acoustics condition has a little effect. |
