Main Article Content
Experimental ballistic investigations were carried out on 03 x groups of bi layered metallic target configurations by impacting ogive shaped 7.62 x 51 mm Tungsten Carbide (WC) core Armour Piercing (AP) projectiles at normal and target oblique angles ranging from 15o to 50o. The projectiles were fired using service rifle at a distance of 10 meters in the ordnance velocity range (820±20 m/s). The groups consisted of 2 x protection shield layout each with applique, fixed space varying angles and fixed angle varying space arrangements. Aluminum 5083 with thicknesses 12.7 mm, 19.65 mm, 31.75 mm and Miilux Pro 500 Steel armour with thickness 4.32 mm were utilized for 04 x configurations whereas 02 x configurations consisted of 4.32 mm Miilux Pro 500 and 6.60 mm Rukki, Raex 500 Steell armour. Non perforation of projectile at a particular angle was taken as the performance measure. It was observed that varying the inter layer space and oblique angle can be optimized to achieve higher ballistic performance with reduced areal density. The order of the orientation of layers with same material and different thicknesses has an effect on overall ballistic performance. The failure modes, deflection of the projectile, impact and exit side diameters of the configurations were also compared.
