摘要:
为了研究高低压室发射弹丸过程中内弹道的参数设计问题,采用经典内弹道理论,结合高低压室发射特点,建立了高低压室发射弹丸内弹道仿真计算模型,设计了一种高低压室发射系统试验装置,对不同喷口大小情况下的高低压室发射弹丸内弹道进行了试验研究,将仿真计算结果与试验结果进行了对比分析,验证了仿真计算模型的合理性。应用该仿真模型分析了高低压室内弹道工程设计中的发射药弧厚、破孔压力、弹丸启动拉力等因素对内弹道性能的影响。研究表明:高压室喷口大小对高压室压力和弹丸初速影响较大,减小喷口半径在一定程度上可以降低火药的能量损失; 发射药弧厚对高低压室内弹道性能影响较大,随着弧厚的增加,高低压室压力降低,弹丸出炮口速度降低; 破孔压力对高低压室内弹道性能影响较小,但应满足高压室内发射药的点火压力要求; 弹丸启动拉力主要影响低压室内压力和弹丸初速,与高压室的压力基本无关。研究结果可为高低压室内弹道结构设计和装药设计提供参考。
Abstract:
In order to study the design parameters of the interior ballistics of projectiles launching from the high-low pressure chambers,the ballistic simulation model of projectiles,which was launched by high-low pressure chamber,was established by classical internal ballistic theory combining the launch characteristics of the high-low pressure chamber. Meanwhile,a test device of high-low pressure lunching system was designed. Based on which,experiment was conducted on interior ballistics of projectiles launched with high-low pressure chamber under various nozzle conditions. The simulation model was verified by comparing simulation results with the experimental data. Then,simulate was carried out to analyze the influence factors such as arc thickness of the propellant,cracking pressures,and starting pull of the projectile on the high-low pressure interior ballistic. The results show that the nozzle size of the high pressure chamber has major influence on the pressure of the high pressure chamber and the initial velocity of the projectile. The energy loss of the propellant can be reduced by reducing the nozzle radius within a certain range. The arc thickness of the propellant also has a great influence on the ballistic performance of the high-low pressure chambers. With the increase of the arc thickness,the pressure of the high-low pressure chamber,and the initial velocity of the projectile decrease. The cracking pressures has little effect on the ballistic performance of the high-low pressure chambers,but the ignition pressure of the propellant in the high pressure chamber should be satisfied. The starting pull of the projectile mainly affects the pressure in the low pressure chamber and the initial velocity of the projectile,and has little relation with the pressure in the high pressure chamber. The research results can provide reference for the design of high-low pressure interior ballistic structure and charge design.
