摘　　要：根据某巡飞弹筒式发射的技术要求,基于气体动力学理论,结合实际高压气动弹射装置的工作原理和特点,构建了内弹道方程组,计算分析了弹射装置主要参数对巡飞弹出筒速度、弹射过程最大瞬时过载等的影响,并通过设置不同的高压气瓶容积以及发射筒长度,给出可以进行车载的合理配置。仿真结果表明,采用一定容积的缓冲腔可有效降低弹射体的最大瞬时过载、提高出筒速度。研究结果可为高压气动弹射装置的优化设计、制造与试验,提供借签。According to the barrel launch technical requirements of a cruise missile,based on the gas dynamics theory,combined with the working principles and characteristics of the high-pressure pneumatic catapult device,we constructed the internal ballistic equation system,and calculated the influence of the main parameters of the catapult device on the launching speed of the cruise missile and the maximum instantaneous overload in the launching process.By setting different high-pressure gas cylinder volumes and launch canister lengths,the reasonable configuration for mounting on vehicles was given.The simulation results show that a buffer cavity with a certain volume can effectively reduce the maximum instantaneous overload of the ejection body and increase the launching speed.The research results can provide reference for the optimal design,manufacture and testing of high-pressure pneumatic catapult devices.
