“近区域”射击“红土地”末制导炮弹弹道模型的研究

The Study on Trajectory Model of Red Land Laser Terminal-guided Projectile when Firing at Near Distance

在分析末制导炮弹外弹道特征的基础上,构建了与末制导炮弹行"近区域"射击时的外弹道特征较符合的"折线法"弹道模型,并用之决定末制导炮弹射击诸元。试验结果表明,"折线法"弹道模型具有以下优点:一是模型能较为真实地反映"近区域"射击时末制导炮弹飞行规律;二是运用该模型决定末制导炮弹射击诸元,精度较高,完全能满足射击的精度要求。

On the basis of further studying and analyzing the trajectory trait, the paper has constructed fold line trajectory model which is correspond to the flying character of red land laser terminal-guided projectile when firing at near distance. The fold line trajectory model is used to calculate the firing data of red land laser terminal-guided projectile. The experiments demonstrate that the fold line trajectory model has advantages as below. One is the fold line trajectory model can truly reflect the fly disciplinarian of the shell when firing at near distance. Another one is that the higher precision can be got when using the fold line model to calculate the firing data of red land laser terminal-guided projectile.
