| 摘 要： | 推导了碰撞产生闪光的射流起爆模型,并利用建立的光纤瞬态高温计测量系统和二级轻气炮加载系统,进行了碰撞速度相近、弹丸入射角度分别为45°和60°(与靶板平面的夹角)时球状铝丸超高速碰撞天然白云石板产生闪光现象的实验测试。实验结果表明:当弹丸为LY12铝、靶板为20mm厚的天然白云石板,碰撞速度分别为1.86km/s和1.96km/s时,弹丸入射角度为45°时的闪光强度峰值大于弹丸入射角度为60°时的闪光强度峰值。

| Abstract: | Jet Initiation Model is derived for light flash created by hypervelocity impact and experimental measurements for light flash phenomena of LY12 aluminum projectile hypervelocity impacting natural dolomite target were conducted at the conditions of near impact velocity and projectile incidence angles of 45 and 60 by using an optical pyrometer measurement system and a two-stage light gas gun loading system. Experimental results show that the peak value of the light flash intensity is bigger for projectile incidence angle of 45 than that for projectile incidence angle of 60 during LY12 aluminum projectile hypervelocity impacting natural dolomite plate, at the impacting velocity of 1.86 km/s and 1.96 km/s ,respectively. |
