do you have one of these planning?

[kevin]

these would be a lot of fun to go driving in the country after a rain

do those angles maybe help deflect incoming rounds? ive allways wondered if an rpg can be deflected or if they just go off on impact and cant be deflected

I think they go off on impact but the angle would help in deflecting the blast. I think...

Besides deflection, slanted armor makes a 1" plate "thicker", because the projectile would have to go through the cross section. It is an effective way to increase the protection level without added material.

i never thought of that!

So that's what happens when they award a tank contract to Volkswagen!

[iocane]

What is that thing called?

[wonderwolf]

tankwagen?

hehee just kidding...that looks like it would be a cool set up in 20mm vulcan or 25mm bushmaster with a MG 42 clone like what they have and 3 guys to run the thing.

PRG, use a shape charge to cut thru the armor like a super high speed cutting torch(the sensor on the tip of the weapon sences the impact, it sets off a base charge at the back of the shell, that shaped charge, with a covering of metal, useally copper or others, then becomes a guided jet of molten metal and fire, cutting thru the armor), thus the best things for them are either laminate armor which stops the shaped charge by the different materials(hard and soft layers, and some ceramics, but its expensive), deflecting it, or reactive armor(the isralies found that a tank was a soft target in urban areas against rpg's thus developed this), which when it hits, blows up with a super fast charge, like blowing the flame out.

Sloped armor gives you a thicker effective armor, from stright on and level, sketch two lines, first stright up and down and measure across, then turn it 45deg, and you get 1.41 thickness to a frontal hit, since tank rounds tend to hit from the front, at high speed this give you more protection(plus some deflection) with the same amount of steel, but you lose space in the tank.

Thats why most of the new smart weapons, look to come thru the top of the tank rather than the front. Less armor usealy.

Its a WIESEL 1 Weapons Carrier that the Germans use.

It has a 20mm automatic cannon and a TOW. Airborne asset, you can put 2 in a CH53.

BTW, thats either a MG3 or a MG74 mounted on it.

Armor, since its incept and use on people, horses, and vehicles is designed to provide deflection surfaces...a perpendicular hit will almost always defeat the armor.

On the RPG, the earlier models used a shaped charge that worked to funnel explosive power into a small area.

The follow-up to that tech is what Okie mentions, the Explosively Formed Projectile, or EFP. It take shte shaped charge, puts a dish of copper on top of the explosive, and the explosive forms the copper into a bullet at a super hi-rate, and the copper slug is moving unbelievably fast (10s of thou mph for a few feet, typically 1500-2000 meters/sec) and cuts rite thru the armor.

I really like the design of the Israeli tanks for deflection surfaces, the Merkavah MkIII:

Also increases tanker survivability by puttung the crew farther back and the power plant in the front.

BTW, Merkavah means "chariot" in Hebrew. Dat is one bada$$ chariot.

Steelcore, read about this thing we are fielding now, its the sensor fused weapon, they make the air launched version, and a ground deployed version, they look for the soft spots on top of vehicles if they dont find one, then they deploy as a gernade, anti personal. One bomb can cover 1500 feet by 500 feet with forty "skeets" self seeking basicaly shaped charges, with optics, guideance and rockets to hit targets within the area.

Heres a website discribeing this, http://www.fas.org/man/dod-101/sys/dumb/cbu-97.htm

WOw...thanks 4 that, Man.
