半穿甲弹风帽气动特性分析

Analysis of the aerodynamic characteristics of the wind cap of semi armor piercing projectile

在半穿甲弹在敌方目标时,其弹头部的特殊穿甲形状可防止跳弹,但是在外弹道飞行时又会影响它的弹道性能。因此分析穿甲弹头部风帽对弹道的影响就至关重要。利用Fluent软件对半穿甲弹风帽进行外流场进行数值模拟,分析风帽表面流场分布,为风帽的外形设计而提供依据。

Armor-piercing shape of warhead of semi armor-piercings will prevent it from ricocheting on combating the target, but at the same time, the shape will influence trajectory performance while the warhead is flying at external trajectory. It is critical to analyze trajectory influence of semi armor-piercing projectile ogives. The software of Fluent will execute numerical simulation on external airflow field of semi armor-piercing projectile ogive, analyzing airflow field characters at the projectile ogive, providing reference for shape design of projectile ogives.
