摘要:
针对弹丸滞留受热身管影响其外弹道初始温度的问题,分别建立了弹丸内弹道和外弹道瞬态受热模型。结合身管传热方程与两相流内弹道模型,采用四阶龙格-库塔法求解热平衡方程和弹道微分方程组,得出飞行弹丸头部温度场分布。该方法考虑了发射前弹丸滞留受热身管的可能性,使其外弹道初始温度的设定更合理,温度场计算结果更精确,符合实际战场环境,为弹丸红外辐射特性研究提供一定的参考价值。
Abstract:
In view of the problem that projectile retention in heating gun tubes affect the initial temperature of exterior ballistics,the transient heat transfer models of interior ballistics and exterior ballistis about projectiles are established respectively.The fourthorder RungeKutta method combined with the heat transfer equations of gun tubes and the interior ballistics models of twophase flow is used to solve heat balance equations and ballistic differential equations.The head temperature field distribution of projectiles is obtained.The methods consider the probability of projectile retention in heating gun tubes before the projectiles are launched.The initial temperature setting of exterior ballistics is more reasonable and the calculation results which accord with the practical battlefield environment are more precise.The methods provide reference for the research on infrared radiation characteristics of projectiles.
