The EXPLOSIONS in to The Battle Of Britain - Storm Of War.....

[Tone71]

Hi all. Been a lurker here for a few years now, waiting patiently for the release of BoB:SoW. Have read many posts with interest but haven't felt much need to reply until now.

I thought this might be of interest to some; here in the UK a TV series was recently aired called Blitz Street, where the effect of various WWII bombs was measured on a mock 1940's street. I have included a link to a YouTube vid that summarises the effect of 3 bombs but I urge anyone interested in the subject to look for the full episodes.

Overview.

Huh very interesting. This makes me feel less frustrated about killing tanks. I used to be annoyed that I could land a 1000 kg bomb within several meters of a tank and not even scare it. I would have thought that even if the tank itself survived, the blast wave ought to kill the crew. However, if people in a little dirt and steel shelter would have suffered only ear damage 22 m from such a blast I should think tank crews would only be stunned. I would assume they all wore ear protection anyway to protect against their own main gun.

sadly its findings are totally false, all detonations are done without fragmentation and just blast from C4. Frag makes all the difference in an explosion, the outcome from 500lb bomb and the equivalent in C4 form are huge.

Frag will not penetrate the tank. The blast however could cause parts of the armor plates on the inside of the tank to disintegrate and cause shrapnels inside the tank - therefore killing crew.
HESH ammo works like that.
Keep in mind all AT weapons are only anti crew weapons, none is intended to wreck the tank itself(pretty impossible).

That depends upon what you think the tank is.

The motor, electronics, ammo, smaller guns, turret bearings, tracks, wheels are all pretty destructible in certain circumstances, and if the thing "brews up", the chances of any of those except the wheels and tracks and maybe the engine surviving is minimal.

Hesh relies on high explosive in direct contact with the outside of the tank. A near miss doesn't have that contact, and is unlikely to break chunks off the inside of the armour. Armour plate is tough and thick. Blast from a near miss is more likely to set off the ammo inside the tank, and that's not really likely either. Injury to the crew through the tank being thrown about is more likely, but even that's not very likely.

Believe me, I am a former tank cmdr.

what does HEAT do? Fry the crew with fluid copper
What does KE dos? the debris it tears off on the inside of (the armor plate of) the crew department are the projectiles to shred the crew.
Also, you dont light up the ammo, it's in a special compartment with a blast door anyway, but the hot oil of the hydraulics. Yummy, fried again.

Hesh: I googled a sec, sorry, it's German, but you get the idea.


S.o. told me once they calculate about 3crews until you have write off the tank, sounds about right. I talked to an Israeli who joined the IDF after the war, their job was to scratch the former crews from the walls - the tank itself was fine tho(or fixable)

its not fluid copper, but acts as fluid because of really high pressure its having against armour plate when going innit in high speed. same thing bit with sabot rounds fired in test shots. (aluminium against something cant remember) the metal flows in metal. metals acts like they were fluid/melt even when they werent, and just because of high pressure.

there been tests done with heat ammo, cuttin cone in several pieces, shot on water and then extracted, to see if they melt together. didnt.


also, for simulation next to come i really hope that planes are not anymore flying 500kg boms when they explode midair/on ground.

most of my deaths in il-2 comes in this sim just because gettin caught by these monster explosions planes make after i shoot at them. sometimes they ignite to burn while i fly past them, then go boom when they are way behind me, killin me too.

there aint so much to go big boom in plane. not fuel can do such huge boom when its still in fuel tank and not perfectly mixed in huge area with air. fuel tank makes more likely buff, not a real explosion. sure it can rip plane in parts but thats just cause of huge amounts of gasses created but not going with high speed. few 10 meters per sec bout maxium.

also, oxy bottle doesnt make huge boom eighter, to explanate those huge booms they make, pressure is going from oxy bottle to every direction and is reduces really quickly in air. in compressed areas oxy bottle booms are different things. and oxy bottles aint that big in planes as well.

and ammo for guns.
ammo for guns would not go boom easily when they are in wings and fuselage takes the hits.
also, if ammo cooks off, it means the cases of ammo would most likely fly off as they are much lighter weight whan the bullets/projectiles. and as ammo isnt in the breech of the gun it means the pressure can spread everywhere and thus not pushing the projectiles in fast speeds like when fired from the gun.

also, projectiles detonators had safetys to prevent them to explode in their own time. some or most of them needed the fast spinning action made by riflin to get rid of the safetys made inside the detonator.

pls Oleg and crew, check again these unreal explosion damages planes make. there is lots of vids in youtube from plane crashes. using gasoline engines. they make no explosions as bombs do make, but fire puffs, which expanding speeds arent anywhere near the speeds of explosions and thus being able to rip stucture of flyby plane at distances of tens of meters.

i have heard a similar story. from an australian who served in vietnam. he talked about him or collegues of his having to clean out the inside of tanks of human remains, sounded rather gruesome

i always presumed the tank would have been disabled or destroyed to, and found it odd they would get soldiers to clean the inside of the tanks where people had been killed (other then maybe removing dead bodies for funerals and identification etc)

never thought they'd be reusing the same tank again later with a new crew
