讨论了炸高达到100射孔弹直径(CD)时射孔弹的穿透性能,到目前为止该炸高远远超过了应用的标准范围(2～7CD)。在实验过程中确定了射孔弹在钢靶中的穿透深度,并研究出一种计算法来描述该结果。实验过程中获得的数据大幅度提高了工程计算法在射孔弹穿透深度建模中的应用能力。这是首次在炸高很大时使用计算方法来估算穿透深度,与实验结果取得了很好的一致性。
The penetration performance of perforated shells up to 100 caliber (CD) is discussed. So far the blast height has far exceeded the standard range of application (2 to 7 CD). During the experiment, the penetration depth of the projectile in the steel target was determined and a calculation method was developed to describe the result. The data obtained during the experiment greatly improves the ability of engineering calculations to be used in perforating projectile penetration depth modeling. This is the first time that a calculation method has been used to estimate the penetration depth at a very high frying height, which is in good agreement with the experimental results.
