射弹侵彻飞机LY-12CZ板材的实验研究

Study of Battle - Damage Prediction Mode of Aircraft Structure Material LY-12 CZ with Projectile

利用普通枪械加速7.62mm弹丸,对飞机结构材料LY-12CZ在射弹打击下的损伤规律进行了实验研究,结果表明:损伤尺寸服从正态分布;损伤尺寸与弹丸着角的余割值成线性关系。同时讨论了损伤模式及机理,参照LATDAM提出了LY-12CZ损伤尺寸的预测模型。

The damage rule of aircraft structure material LY-12 CZ with projectile is tested and investigated by accelerating the 7.62 mm pill with the ordinary gun. Through the analysis of the experimental results, the conclusion shows that there is a linear relationship between the damage size and the cosecant value of pill velocity angle; the damage size is distributed in normal school. Simultaneously the damage mode and the mechanism are analyzed, and then a battle-damage degree forecast experimental model of LY-12 CZ is put forward in the light of LATDAM.
