摘　　要：以末制导炮弹发射热安全为背景 ,根据弹丸不同部位受热方式 ,建立了末制导炮弹滞留预热身管受热的两维瞬态模型 .根据相似理论采用方程分析得出了相似准则 。A two dimensional transient heat transfer model for terminall guided projectile in heated tube is established to study the thermal safety of the projectile. Non dimensional number has been obtained by the principle of similarity and equation analysis. The effects of different heat transfer model on the process of heated projectile have also been discussed.

关 键 词：末制导炮弹 热安全 相似理论
