Leopard 2A5 Turret Composite Armor Vs 120 mm M829A2 APFSDS-T Part-2

This video presents 120 mm M829A2 APFSDS-T penetration against Leopard 2A5 tank Turret composite armor. This video is updation of part-1 with few improvement in composite armor. It is found that, the projectile is successfully able to penetrate the front turret plates as well as whole composite armor (NERA) plates. The video highlights various penetration angle. The assumption are mentioned at the beginning of the video.
The Leopard 2A5 turret armor and projectile is simplified for the analysis. The APFSDS-T fins and ballistic cap is ignored in the simulation.

    I eonder why does the rod deflect downwards so much, the force exerted on the plate is down, so it should bounce upwards if at all (APFSDS dont reqlly get defelected/bent unless in extreme angles) Also the NERA plates should get caved in, feeding the front plate into the penetrator, and then bounce back, feeding the back plate. That is what makes RA so effective, it makes projectiles go through way more armor than they actually should. The more spaced and angled, the more pronounced the effect is...

    The main role that these wedges have is to change the path of the incoming Projectile. It penetrates the wedge and then starte so change it’s flight path. It then hits the main armory at a slight angle. That’s wha makes the turret so hard to penetrate. And that’s the reason the T14 is one of the only tanks that (supposedly) can penetrate the turret. Because the APFSDS dart is long enough that the start and the end of the dart both stay “connected” to the Armor. That way the wedge is unable to change the incoming angle that the dart has.

    Leopard 2 uses perforated armour plates with glass or ceramic reinforced polymer in the holes. Polymer was replaced by tungsten with A5 armor upgrade The holes are sized and placed so that a penetrator hits a part with low and a part with high density. This causes the penetrator to bend or wander of similar to a drill in objects with mixed hardness. To prevent the plugs from simply being pushed out of the holes a polymer plate is placed between each plate Backstop plate is actually 2 plates with a layer of polymer between because that allows the softer back plate to absorb some impact forces to prevent shattering of the harder front plate

    In other stimulations I've seen of similar parameters, the rod orientation is changed ≈1° by impact of the forward most plate and prior to impact with the inner plate (where 2A4 armor would begin). Is the penetrator in this simulation "on rails," or are there other factors differentiating this result?

    That part is probably the most accurate part of this simulation… the simulation is unlikely to fail when the armor configuration is just a sloped plate. The part where this simulation is incomplete is the composite armor material. Apfsds is unlikely to be that affected by angles. It may bend a little, but turning 90 degrees is nonsense. In order to make it bend more, they probably used other materials for the wedge, which is not shown in the simulation.

    Is this simulation accounting for the reactive element of the NERA array or is it treating the "rubber" element as static (ie just based on it has a hardens of X and a toughness of y and ignoring the fact that "rubber" bulges energetically into the projectile)? Also what are you basing the material properties on the NERA off of? As far as I know the specific characters of the polymer ("rubber") used is highly classified.

    My understanding of the space between the initial plate and the subsequent armour is intended to allow the impact of the initial penetration to destabilise the projectile to such an extent that it's energy is not so focussed when encountering subsequent layers. As the simulation shoes, little of the round breaches the crew space; with greater diffusion of energy from being unstable it could be that the armour model will have worked.

Edit: As your "reliable" War Thunder source says, the 35mm outer plate of the turret armor is HHA, not RHA. And at least one of the plates of the wedge should also be HHA and not RHA.

    Even without shattering, the angle of attack of the penetrator would be such that it would approach the composite armor at a non-perpendicular angle, dramatically increasing the effective thickness of the armor. Also it's not inertia that isn't modeled here, it's destabilization; specifically the perpensity of a projectile to destabilize in flight after penetrating a non-perpendicular surface.

    For a bit it does that to some extent, visible on the tip being bent almost backwards spreading the forces *almost* enough to fully disintegrate the projectile. Sloped armor also works as "thicker" armor than the actual thickness. And the chambers "muffling" the shrapnel/hot gas is just beatiful to see at work! So much knowledge, thoughts and technological achievements put into something as "simple" as armor! Just marvelous what materials humanity is able to create and utilise! All this combined and it's still defeated by "just" throwing heavier stuff faster which itself is a technological marvel to pull off xD

I suggest you take a much deeper look at the pictures available of the plates.

    Compounded angle of impact is something like 30o *50o==1.58 * LOS. Most research papers examining modern armors feature 1/2 dozen thin plates stacked short distance apart. As Each plate is penetrated the penetrator tip is slowed in relation to the tail speed.. When the tip clears each spaced plate ; the speed normalize to the tail speed ; , but erosion continues until equilibrium occurs. This should weaken the tip as it continues to penetrate "follow on " spaced plates, undergoing the same strain effect. Calculating this; each spaced plate adds one plate thickness plus the one rod diameter to the accumulated block resistance.: source ; 19th Int. Symposium of Ballistics TB16; pp1167 to pp 1174

    Why, when hitting the outer layer of armor, part of the energy and the projectile is "reflected" thanks to the angle of the plate, and inside the simulation does not take into account the inclination of subsequent layers? With successive plates arranged in this way, the energy of the projectile would be dispersed vertically and certainly the remains of the sabot would not fall into the interior in the place where it is shown. As long as there is enough energy left in them to penetrate inside, the same penetration should take place somewhere near the ceiling of the tower, and not at the height at which the bullet hit the first layer ... Next plates are set on an specify angle to additionally they absorbed energy and changed the direction of its dissipation.

    Seems unrealistic that a rod would deform and bend that extremely at the tip without changing its flight angle at all. Just ask yourself: What force is bigger? A force that could bend a thick tungsten or DU rod that much, or the inertia that keeps that rod on course? As much forward momentum as such a projectile has, the force that keeps it on course is actually rather flimsy, which is the whole reason why you need to stabilize it and why accuracy is an issue. Wind can blow it off course at long enough distances traveled. Imagine the enormous perpendicular force necessary to bend the rod into a hook shape. There is no way it would just keep flying straight like a laser beam, no matter how fast it is. The wedge-shaped addon armor is supposed to make the penetrator tumble before it hits the main armor. There would be no point to it, if rods interacting with it would just be able to continue on their path undisturbed, like shown in this obviously flawed simulation. Also, as others have pointed out, the composite sandwich armor is not made of simple steel plates.

  • @J7Handle

    @J7Handle

    Жыл бұрын

    Knocking a tungsten or uranium rod off course does indeed take time. If you do it in a few hundred microseconds, which is what happens here, the amount of time is so small that the forces necessary to deflect the rod in that time would break the bonds between the atoms and massively deform the rod. Recall that in order for the entire rod to be deflected as a unit, the forces would need to be transmitted across the entire rod from where the forces are initially applied. When the forces are very high, they cannot be fully transmitted across the gaps between atoms and the rod deforms. The forces may not look very high from the simulation, but that's because the time is slowed down by several thousand times. In reality, the rod is traveling at 1675 m/s and the entire sequence happens in about 1 millisecond.

All I can say is that whatever physics education you've had has not gone past the basics, and you should really do a lot more research. Given that you say "in school", I assume you never had any physics courses in college, if you even went. For the record, high school physics classes assume "rigid bodies", "negligible friction", and other such approximations that absolutely do not work for high velocity impacts. Edit: Actually, here's something. Have you ever seen a video of someone shooting lead plate with bullets? The plate craters and the bullets flatten into the shape of the crater they create. Have you ever held lead? It's solid metal, but it turns into play-doh when shot out of a gun.

    From what I've learned, the purpose of the thin, angled armor on the front of the turret is not to resist the penetrator but to disrupt its flight attitude. Any change in the pitch or yaw of the penetrator will have a significant effect on its ability to penetrate the main armor. In this simulation there's no real change in the rod's flight attitude, which is pretty unlikely. By all accounts this thin spaced armor is quite effective, so much so that the Russians are considering lengthening their penetrators to help deal with the issue.

    Try not to aim at the turret....perhaps. I know a few gunners and very seldom is the target area the turret. A sly AT4 at the back end is usually the best option. Tanks on the modern battlefield need a lot of boots on the ground to secure their advancement. If an area hasn't been secured there is no way a tank crew is zooming off up the road. Most armour now is reduced to a support role. They need high maintenance to keep them looking pretty. Night vision for troops on the ground would be a better investment.
