潜射导弹燃气蒸汽式发射装置的内弹道建模

发射过程中的内弹道建模是潜射导弹变深度发射的关键技术之一。按冷却水状态将燃气—蒸汽式发射装置发射过程分为4个阶段,本文主要针对各阶段的内弹道进行理论分析和建模,得出了整个发射过程中发射筒内的内弹道模型。将该内弹道模型应用于某实例,计算结果和实验结果吻合较好,这表明该内弹道模型具有一定的准确性和实用性,一定程度上可以预示发射筒内工质气体的状态参数及导弹运行参数。

Interior ballistics modeling of submarine-based missile launching unit

Interior ballistics predication is a key problem in gas-steam variable depth launching dynamics system.According to the phase change of cooling water,the whole process was divided into four stages,and mathematical models were presented individually,resulting a fully formulated mathematical model.Numerical predication was carried,and results matched well with the experimental data,which says the usefulness and accuracy of the model were validated.
