Bazooker fuses question

[obear71]

are they like rifle nades, you need a good 90 degs angle to make them fuse and explode or will they fuse on any angle?

[firebugs]

I've had a couple not explode, but by and large it appears they fuse on about anything.

[Voodoo1]

I can't get knack of things at mo

[rubbish]

You need a good angle.

The 1940 versions of the British HEAT rifle grenade (first generation) were especially fussy about near-90-degree impact because of a fuse design issue.

The 1944 versions of the American and German HEAT projectors (American third generation, German second generation) were well wrung out design-wise. Their fuses would operate across a wide range of impact angles. Of course, HEAT charges in general are less effective when penetrating armor at angles well off 90 degrees, not just because of the greater effective thickness but also the jet geometry disruption that can occur when crossing through the initial density transition at a significant angle.

What the hell are you trying to do? You're gonna make the forums asplode with that kind of talk!

This.

Think of HEAT as a temporary fist of superheated penetration (which it is, the mechanic is kinetic and not 'burn through'), it has only a narrow cone of a foot or two of punch before it dissipates.

So if you have something that say penetrates 160mm, if you are 90 degrees you are golden against most anything in game, but if not you may be just putting scorch marks on the paint job.

Also keep in mind that the warhead effect is likely different, you're dealing more with superheated spall and whatever is in range of the plasma jet, not an APHE round exploding inside the tank and not a solid shot passing through in its flight path with whatever joules are left.

Also, the actual penetration caused by your average HEAT round is rather small... maybe a 5mm hole.

Less efficient shaped charges make bigger holes, but penetrate less.

But would it spray lava all over the crew if it hit the crew compartment?

Kind of like those IEDs that were introduced in Iraq, I don't remember what they were called (EFP, i think)??

EFP means explosively formed penetrator. its basically a tube packed with explosive with the business end having a concave copper liner. when it detonates the copper slug is melted and sent out at a velocity of about 1km/sec if im not mistaken. The shaped charge of the RPzB. Gr. 4322 panzerschreck round is spaced geometrically perfect so the concave cone with focus perfectly at the armors surface.

You know, Matilda IIs should be practically immune from Panzerschrecks from the side, they have thick skirts to protect the tracks and wheels and stuff. Not that that will do them much good in Tier 2.

If the jet penetration is at a clean location (i.e. not through shell cases, not through other equipment that have the effect of absorbing energy), the jet will tend to throw droplets or particles straight across the interior until they collide with the opposite wall, which will dissipate most of their energy.

Of course, if the jet has a lot of residual energy (i.e. a HEAT round cleanly penetrating a fairly thin armor surface, so that the jet still has lots of energy when it emerges from the inner surface) and it aligns with and intersects a crew member, he will be injured or killed.

Jets also can damage interior equipment, but they usually don't penetrate far-side armor except maybe in the very lightest-armored instances.

A penetrating AP shell creates a wide-angle spall-spray into the interior. If the shell is APHE, the interior burst is generally somewhere between radial and omnidirectional. A penetrating HEAT jet, OTOH, is a narrow-angle event.

But the Churchill is what the panzerschreck will accel at.

[Scotsman]

You need at least 10% penetration margin to be effective against your target...

Skirts or any kind of armor spacing is currently not modeled in game. Realistically it should provide some advantage against HEAT weapons, but it's all treated as one thickness so there isn't any advantage conferred in game.
