Скачать или смотреть TRIPLE BARRELLED KV-7 (U-13) vs Panzer IV F2 | Face Hardened Armour Penetration Simulation

The experimental KV-7 (U-13) featured a triple-cannon arrangement, with 2 45mm and one 76mm cannons. The simulation presents a volley from the KV-7 impacting the Panzer IV F2's 50mm upper plate at a side angle of 15°, from 250m.

Face hardened armour (FHA) was common on early war German tanks; this type of armour featured an extremely hard front face, with the remainder of the plate being tougher and more ductile. The intention of this was to cause projectiles to shatter or deform on impact, dissipating their energy, instead of the armour having to deform and absord the energy. The FHA has a 5mm portion of 600BHN steel, with the remainder being 350BHN. The bulk is still relatively hard, with low elongation, hence the very noticeable shear bands which form.

The projectiles are the 76mm BR-350B projectile, with hardening upto ~450BHN at the nose, as well as two 45mm BR-240 projectiles, with more uniform hardening, of upto ~500BHN. In reality, the 76mm projectile would impact the plate much later than shown in the simulation, due to its lower muzzle velocity.
