Once upon a time (regarding bombs)

[SR-F_Winger]

There was a thread with information on damage of bombs and how far from target they are stiil effective. Does anyone by chance have a clue where to find that thread?

 

I used search but didnt find anything.

 

Thanks

THANKS!!!!!

THANKS!!!!!

What are the overall opinions on this? Do you guys think thats realistic?

 

EDIT: Shouldnt the pressure wave alone from a 1800 kg bomb kill all life inside a tank when it explodes that close?

I have no clue. Just a feeling. So maybe someone with more knowledge could elaborate?

I think the crew of a tank that just experienced a 1800kg bomb go off 30m away would propably all suffer burst ear drums, posibly light concussions and some might be temporarily incapacitated. But killed? No, that's unlikely.

 

Blast waves from detonations can definately kill you, but they dissapate very quickly in open space and are deadly at much shorter ranges than most people realize. This is why a land mine, which has enough force in the blast to completely blow away a soldiers lower leg often doesn't even have enough force to burst his ear drums just a few feet further away. Detonations within an enclosed space (such as a hand grenade thrown into a building) is a different story, here the effect is amplified by the wave being reflected from the surrounding surfaces, and the effect on the body is often increased by several orders of magnitude.

 

When a bomb detonates in an open space however, the blast wave is only deadly at a relatively short range, much shorter than the distance where a person standing in the open are certain to be killed by shrapnel. the far majority of people killed by explosions die from shrapnel injury or having buildings collapse on top of them. The human body is actually quite resillient to shock waves and it is posible to survive blast waves of up to around 50 PSI overpressure (though you'd definately be incapacitated at 25 - 30 PSI). In comparison a light wooden building can be blown away by just 5 PSI overpressure, which isn't even enough to burst a persons ear drums. This means, that contrary to what common sense would tell you, a blast wave that can blow a house clean off its foundation can be survivable to an unprotected person standing right next to it, provided he isn't hit by shrapnelor pushed into a hard surface or something.

 

Inside a tank, the crew is almost completely protected from shrapnel and they are fairly well protected against blast waves too. Blast waves tend to "wrap around" objects and would propably find a way into a tank that isn't completely air tight, but it would lose most of its energy doing so. Anyone who's been inside a tank knows, that sound doesn't travel well from the outside to the inside. Basically: You can't hear jack of what's going on outside. Blast waves are not fundamentally different from sound waves, and would lose most of its energy when transfered through the shell of the tank. When the dust settles after a 2-ton blast right next to a tank, the tank itself might be covered in debris and the outside heavily scarred from shrapnel, but it would still be in working condition and the crew likely alive but extremely uncomfortable and posibly unconcious.

 

Tanks can of course be disabled and the crew killed by heavy explosives without penetration of the armour, but this usually requires a direct hit (i.e. the detonation happening directly on the tanks surface. This produces an effect called "spalling" which involve pieces of metal being broken off the inside of the tank and flung around at high velocity inside the tank with results not unlike turning on a blender  This was how the big Su-152s of the Red Army were used to kill German heavy tanks and earned their nickname "Zveroboy".

I have been quite near to a number of very large explosions, as Finkeren says the pressure/blast can easily damage light structures but needs to be in a different level  to cause human fatalities

Day before yesterday I was tanking in my T34 on DED server and witnessed direct hit of 50kg bomb from Emil rendering my Russian comrade in leading tank to burning can. Nice hit! But then Emil got greedy and made a dozen attacks at me only with board guns. Enough time to pepper him with my Degtyarev. He tried to ram me on his final way down in flames,but missed :D

Thanks guys for the opinions. So what we have in game is modeled pretty close to reality. Nice!

Food for thought, this is regarding IEDs in Iraq.

 

"Here's why IEDS carry such hidden danger. The detonation of any powerful explosive generates a blast wave of high pressure that spreads out at 1,600 feet per second from the point of explosion and travels hundreds of yards. The lethal blast wave is a two-part assault that rattles the brain against the skull. The initial shock wave of very high pressure is followed closely by the "secondary wind": a huge volume of displaced air flooding back into the area, again under high pressure. No helmet or armor can defend against such a massive wave front."

...or no brain. No brain,no rattle

This was the affect of 1,500 KG of ANFO on Manchester's Arndale Centre. That's a home made explosive. I wouldn't fancy the chances of human life surviving that inside a tank or not from 30m.
