建立了基于阿累尼乌斯公式和粘性流体力学的固体燃料冲压发动机（ＳＦＲＪ）简单反应流模型，并在该模型下对某实验发动机进行了模拟，得出了燃烧剂组分、燃速、温度等发动机参数的变化趋势，给出了一些有用的结论。结果验证了该模型的可靠性。
The simple reaction flow model of Solid Fuel Ramjet Engine (SFRJ) based on the Arrhenius formula and viscous fluid dynamics was established and an experimental engine was simulated under the model. The combustion composition, Temperature and other engine parameters of the trend, given some useful conclusions. The results verify the reliability of the model.
