| 摘 要： | 本文建立了采用气体驱动弹射-回收的抛放弹弹射机构的数值计算模型,用经典内弹道和气体动力学理论分析了火药弹燃烧、弹射活塞完全推离悬挂物(导弹或炸弹)并回缩到初始状态的整个过程.给出了对某型号挂弹钩的实例计算,计算结果与试验结果基本相符.最后简要讨论了不同参数对弹射效果的影响.本文所建立的计算模型为该种弹射装置的优化设计奠定了基础.

| Abstract: | A model of blank cartridge ejection device was established and the ejection and restoration processes described. The process beginnng from powder burning to the ejection pistons pushing out the bomb and its moving back was analyzed applying classical interior ballistics and gasdynamics theory. A case of ejection device was calculated, and the effects of different parameters on the ejection velocity were discussed. This offers a theoretical basis for the optimum design of such a device. |
