ERA simulation | Explosive Reactive Armor

115mm 3BM4 APFSDS (3.2kg hardened steel penetrator [up to 650BHN], max diameter 42mm + 0.19kg steel cap, 4kg total) at 1600 m/s

vs

100mm armor at 60 degrees + 10mm ERA plate

3BM4 performance vs sloped and spaced armor:

*Velocity view is bugged due to the simulation crash. Everything was red xd*

*Initially, it was supposed to be a Nozh ERA simulation. However, similar to HEAT simulations, there was a computation time problem and I didn't want to present an incomplete simulation so it's just simple ERA*

So this is kind of like kontakt-1? With a thin plate to be fed into rods trajectory? Does this mean with a thicker plate it would be kind of like relikt?

[lunarrocks]

we have to remember that ERA blocks that work against kinectic projectiles work on the principle on moving their plate sideways parallel to the main armour plate as to divert the projectile to a more oblique angle when contacting the main armour plate (like kontakt-5)

[Pribumi]

The armour itself got the shock from the ERA, pretty fascinating for me.

[slowlydying]

Very cool, it's always a good day when you upload

[MrBsvc]

Those ripples in the armor in the last simulation were really cool to see

[normalicious]

Would it be possible to simulate the penetration capabilities of the shrapnel?

[garchamp]

How much did the ERA help the armor, if at all? It would be interesting to see the simulation with an unmitigated impact for comparison.

Sooo cool
I love how these sims ger more and more advanced

[Novous]

Recommendation: show two versions side by side with same camera angle so laymen can understand the effect it has. Era vs non era in this case. In other ones heat vs aphe, etc. An undersized vs oversized round against the same plate. That way you're illustrating what "normally happens" vs "what happens in this exceptional case"

[gastonbell]

These simulations really reinforce the idea that momentum = energy. The astonishing velocity the tungsten rod is traveling at means that it's basically unstoppable by anything reasonably sized - all they can hope to do is blunt it or change it's course slightly so that it does LESS damage when it hits.

[PrestonGaming]

Definitely need to see simulated crew and internals getting hit. I love your stuff man!

[tonyhind]

I fine these so therapeutic and it scratches my nerd itch.

[shdwdrmr-dqlo]

I'm a simple man - I see a new Dejmian XYZ simulation, I watch and give a like.

[Re-]

Interesting based on this type of ERA it would work well against HEAT rounds but against KE projectiles it serves more as an extra steel plate on the armor unless it's kontakt 5

[maximilianhaller]

interessting that the explosion of the ERA will not destroy/damage the rod enough to fully stop it. Thanks for that simulation, great work mate!

[HanSolo__]

Very, very nice! Any assumptions regarding Erawa1 and 2 behavior in a similar situation?

[samspeed]

Cool sim. I think you got quite a lot of good simulation before the program crashed.

[marcosmejia]

I know it would probably take long but you should do a Gustav gun vs something like the is-7

[uwuowo]

Can you do a pressure simulation on how much ERA affects the crew inside

[Temmie]

great video, shame the simulation crashed
