An illustration of why sloped armour offers no weight benefit when protecting a certain frontal area. Comparing a vertical slab of armour (left) and a section of 45° sloped armour (right), the horizontal distance through the armour (black arrows) is the same, but the normal thickness of the sloped armour (green arrow) is less.
It was determined by a study of a possible Chobham-armour protected MICV that a completely new design using only Chobham armour for the most vulnerable front and side sectors (thus without an underlying steel main armour) could be 10% lighter for the same level of protection against KE-ammunition, but to limit costs it was decided to base the ...
Sloped armour on the front of Soviet T-54 tank, here cut open to demonstrate the increase in effective thickness. Simply sloping a piece of armour inherently increases its effectiveness by increasing the distance a projectile must travel to penetrate it. It also increases the odds that a projectile will ricochet off the target without causing ...
Basically it seems to me that the horizontal armour has been ignored, unless it is open space, which is not so good for armour. Taking a 45deg slope versus straight, and say a 30cm length/height with 10cm of armour. Right angled armour @ 10cm Area would be 30x10+(30-10)x10=300+200=500 sq cm Sloped armour at 45deg would be 42.4x10 = 424 sq cm
Xblocs are typically applied on an armour slope steepness between 3V:4H and 2V:3H. Unlike natural rock, the hydraulic stability does not increase at shallower slope inclinations, because, in that situation, the interlocking effect is reduced. Standard Xbloc sizes vary between 0.75m 3 (significant wave height up to H s = 3.35m) and 20m 3 (H s ...
The D9 armour deflected RPG rockets and even 9K11 Malyutka (AT-3 Sagger) ATGMs. Slat armour is designed to protect against anti-tank rocket and missile attacks, where the warhead is a shaped charge. The slats are spaced so that the warhead is either partially deformed before detonating, or the fuzing mechanism is damaged, thereby preventing ...
The affected vehicles are the Kia Niro from 2023-2025, Niro EV from 2023-2025 and the Niro plug-in hybrid from 2023-2025.
More ammunition and fuel, very minor armour increase. [46] New hexagonal turret, nicknamed "Mickey Mouse" by the Germans because of its appearance with the twin, round turret-roof hatches open. Later production had a new commander's cupola. The T-34-85 (German designation: T-34/85) was a major improvement with an 85 mm gun in a three-man turret ...
