摘要
通过分析固体燃料冲压发动机内部燃烧和流动过程,建立了固体燃料冲压发动机内弹道计算模型。在数值模拟基础上,分析了发动机内流场结构和燃速特性。理论计算表明发动机内流场呈现很强的二维特征,附着点位置与入口台阶高度和燃烧性能有关。为验证计算结果,设计并建成了固体燃料冲压发动机实验系统。
With the inner combustion and flow analysis of solid fuel ramjet(SFRJ),the internal ballistic model within SFRJ is established.On the basis of numerical simulation,inner flow field and the performance of regression rate are analyzed.The theoretical calculations show that the inner flow field presents strong 2dimension property.The reattachment point depends on the inlet sidestep height and combustion property.To verify the calculation results,a SFRJ test system has been designed and established.
