| 摘 要： | 以研究炮射末制导炮弹发射热安全性为背景，建立了末制导炮弹滞留预热身管中受热的一维瞬态简化数学模型，仿真了某大口径火炮在不同射击方案以及不同环境温度下，弹丸滞留身管中的温度响应过程，并预测了其安全停留时间，部分仿真结果得到相关实验的支持。建立的模型与方法对于弹丸发射尤其是末制导炮弹发射的热安全性设计与评估具有普遍的理论与实际意义。

| Abstract: | A one-dimension transient heat transfer model for terminally guided projectile stayed in heated tube was established to study its thermal safety. The safe time and temperature response of the projectile were simulated and the results are validated by comparison them with the experiment data. The effects of firing rate, firing round and environment temperature on the projectile were also investigated. |
