This study was conducted on a linear shaped charge with a double-angle liner.The double-angle liner has a large inner apex angle and a small outer liner angle.Experiments and numerical analysis were performed in a penetration performance study, and it was GEL INTIME confirmed that the experimental results and numerical analysis results matched well.
As a result of the numerical analysis, at the standoff distance of 1.5 CD, the penetration performance of the double-angle linear shaped charge was improved by 14.5% compared to the conventional linear shaped charge, and at the standoff distance Horn Tweeter of 2.
5 CD, the penetration performance was improved by 12.5%.For miniaturization, numerical analysis was performed by reducing the height of the explosive and the standoff distance.
As a result of the numerical analysis, the penetration performance of the double-angle linear shaped charge was improved by 14.6% compared to the conventional linear shaped charge.Double-angle liners are effective in improving the penetration performance of linear shaped charges.
