So, about tanks...

[Kaneohe]

I. What, exactly, does armor slope do? Does it just richochet shells more easily?

II. Is there some way to calculate how effective a tank's armor is? (ex: Is the KV-1S's 75mm/30-degree-sloped front armor better than the T-34/76's 45mm/60-degree armor?)

 

[Capt.Marion]

do a search on the slope and armor increses, someone posted a calculator for that. And yes, sloped armor does make the projectiles more likely to ricochet and do no damage, unless they are High Explosive (HE), that is.

 

[Kaneohe]

Thanks, found it.

I can rember, that someone said, russian armor, even though that it was sloped, wasnt that effective with some tanks, cause of flaws in the material, compared to the german armor.

Well IIRC, late war panther armor was not as good either due to drop in German production quality of armor.

 

[jedinstven-o crni Wuk]

yes i have read about that as well. But it was still superior compared to allied armor plates. Just below german standarts from past.

The armour slope doesnt just cause a shell to ricochet, the thickness of armour an AP shell traveling horizontally has to go through is greater plus for a given wieght of armour plate more protection can be gained. If you are that interested see if you can get a copy of Design and Development of Fighting Vehicles by R.M. Ogorkiewicz

Face the wall punch it.

Face your cars windsheild punch it.

It hurts less to punch the windsheild because the energy of the blow is deflected away from the windsheild.

As a practical matter, angled armor functions as if it were thicker vertical armor. This means you can put less armor on your vehicle while retaining the same (or virtually the same) level of protection. And THAT means that you can have both fast and well armored vehicles, as opposed to simply slapping on thicker (and heavier) vertical armor, which will make your top speed slower, OR require you to put in a more powerful engine (which can then lead you to guzzle more gas, and so on and so forth).

like the meat tells ... diagonal you have to "cut" more and need a sharper knive


the Tiger-fibel alone is a reason to learn german. They have the best expamples ...

Works better with headbutts

The simple fact is that the sloped armour gave it more thickness. So if it's 50mm at 90 degrees it would be 60mm at 45 degrees.

how did you come to this idea??

This is correct, take a piece of notebook paper, the distance from left to right along the printed lines is 11 inches (or whatever).

Now fold the paper diagonally at 45 degrees from the top corner. (like a paper airplane).

The length of the crease will be greater than the width of the paper.

Now imagine what happens when you tilt a 3 inch plate at a 45 degree angle. The distance the projectile has to travel through the plate is increased substantially since tank shells travel relatively level to the horizon.

I doubt a molten jet of copper will deflect off the angled surface at all. And a kinetic round is moving very fast, so it is probably gonna turn that armor into butter.

 

[OneShot]

The frontal armor slope on tanks has always been done primarily to increase the effective thickness, and to increase the tendancy for incoming shells to glance off without transferring energy effectively. Engineering reason for providing a slight slope on turret profiles is not so much to increase the effective thickness or encourage a slightly higher percentage of off-angle shots to glance off without transferring much energy. Rather it is to keep the effective target cross-section of the uppermost extent of the tank, which is the part that is unavoidably exposed to enemy fire under defensive conditions, as small as possible, while maximizing the turret bearing diameter for maximum strength and stability, and maximizing the room at the base of the turret for such essentials as the gun breech and loader, recoil clearance and crew bodies.

Geez, dont ask a common sense question about tanks, it'll get locked for sure. LOL

But in any case, the angled trajectory will meet with a thicker object than a perpedicular trajectory. Its just physics. Although, I think sometimes that netcode ect ect found in online play in anything makes it all seem like "hitpoints" at times. YMMV

 

[SgtSwanson]

Well, if you want to put it that way..... then 3" of armor at 90o would be worth say 100 pts. And if you slope it to say 45o then it would be worth say 250 pts.

Simple:

 

[blkmgc]

^ Good illustration. Now ,thinking in 3 dimentions, turn the angled piece any number of degrees forward or back in the horizontal plane, and it becomes even thicker.
