METHOD FOR DETERMINATION OF PENETRATION DEPTH OF TARGET WITH ARMOUR-PIERCING SHELLS Russian patent published in 2019 - IPC F42B35/00 

FIELD: physics.

SUBSTANCE: invention relates to methods of evaluation of efficiency of armour-piercing ammunition and armour at their collision. Method of determination of depth of target penetration by armour-piercing projectiles consists in determining length of shell l and density of its material k_c. Density of target material k_m is determined. Shell velocity is determined at collision moment u_i. Sublimation heat of one mole of material of projectile material E_c is determined. Weight of one mole of material of projectile material P_c is determined. Determining the sublimation heat of one mole of the target material of the target material E_m. Determining the weight of one mole of the target material substance P_m. Penetration depth of the target h is calculated using a ratio. Analysis of collision of kinetic projectiles with targets makes it possible, at the stage of designing projectiles and armour, to determine target armour penetration parameters.

EFFECT: invention can be used in creation of new ammunition and new armour for protection of objects.
