摘　　要：简述了冲压增程炮弹的增程原理,建立了固体燃料冲压发动机内流场的流动及燃烧模型;对60mm实验发动机内流场进行了数值模拟,并通过与国外实验数据的比较,证实了该模型正确;通过数值模拟结果分析入口空气状态对发动机推力和比冲性能的影响,所得结论对冲压增程炮弹的设计具有较强的理论指导意义。The range extended theory of the solid fuel ramjet （SFRJ） projectile is simply explained, then the flow and combustion model of the SFRJ is established; A 60mm experimental SFRJ is numerically simulated, and comparison between the calculated results and the abroad experimental data confirms the correctness of the presented simulation method. The relations of thrust and specific impulse to inlet air states are derived based on the calculated results. The conclusions are available for the design of the SFRJ projectile.
