摘　　要：水平弹射装置主要用于空基导弹武器的发射,提高其弹射内弹道性能对武器的成功和安全发射具有重要意义。针对某活塞式水平弹射装置的内弹道工作过程进行了研究,建立了弹射工作过程的力学分析模型,并结合零维内弹道理论,完成了内弹道数学模型的构建。基于MATLAB软件编制了计算程序,采用四阶龙格-库塔法求解其内弹道方程组,并能够根据所设计的弹射药型模拟计算高、低压室压强曲线和导弹运动规律。同时,考虑点火过程对弹射的影响,建立了引燃药柱的燃烧模型,对内弹道仿真计算程序进行了优化,并将优化后的内弹道程序计算结果与试验数据进行了对比。结果表明,仿真计算结果与试验曲线吻合较好,误差在5%以内,可为同类型的水平弹射内弹道性能预测提供理论指导和借鉴。The horizontal ejection device is mainly used for the launch of air-based missile weapons,and improving its ejection interior ballistic performance is of great significance to the successful and safe launch of weapons.In this paper,the interior ballistic working process of a piston-type horizontal ejection device was studied,the mechanical analysis model of the ejection working process was established,and the interior ballistic mathematical model was constructed combined with the zero dimensional interior ballistic theory.The calculation program was compiled based on MATLAB software,the fourth-order Runge Kutta method was used to solve its interior ballistic equations,the pressure curves of high and low pressure chambers and the motion law of missile could be simulated and calculated according to the designed ejection charge.At the same time,considering the influence of ignition process on ejection,the combustion model of ignition grain was established,the interior ballistic simulation program was optimized,and the calculation results of the optimized interior ballistic program were compared with the test data.The results show that the simulation results are in good agreement with the test curves,and the error is less than 5%,which can provide theoretical guidance and reference for the prediction of interior ballistic performance of the same type of horizontal ejection.
