Blast zones from a single bomb or multiple salvo'd bombs

[Lusche]

Here are my complete ordnance test results thus far:

These are the values HT himself posted a few years ago for bombs, nothing has changed since then:

4,000 lb   20.000
2,000 lb   11.000
1,000 lb   6.400
500 lb   3.600
250 lb   2.000
100 lb   1.000
   
1,800 kg   21.780
1,000 kg   12.100
800 kg   9.240
500 kg   7.040
250 kg   3.960
100 kg   2.200
50 kg           1.100


The points given are used itnernally by the program, just assume 1000lbs=6400

I would need a better terrain for such test that those currently available.

Hmmm.  Interesting.

^ That is the damage done assuming a direct hit.

The post is about blast zones, which I consider splash damage, or diameter of effect.  How does bomb size affect radius of effectiveness? If and how does the damage decrease with distance from target, and how does the size of the bomb itself figure in.

IMO anecdotal input- I found it much easier to kill a tank with 1x500lb bomb on either side of the tank, than with a 1000lb indirect hit. The bidirectional concussion blast is probably greater than a single direction blast of double the force....?

As far as the differences in blast radius go, judge for yourselves:

Take up B29's using 1 of three configurations:  the 1k, 2k, and 4 k bombs.  For starters, simply make a pass over the main area of town (roughly 2 to 8 O'Clock), drop 2 1k bombs together and film it.  Watch the "spread" of the dual 1k bombs, then SINGLE 2k bombs, and then SINGLE 4k bombs.  I've seen the 4k bombs reach out and grab auto ack further than one would think.  

Remember this: you can drop all the 1k bombs you want and maybe have a "longer" blast radius due to the number of bombs being dropped, but the width of the blast radius is the *same*.  If a player wants massive damage in a single pass then larger bombs are the way to go.  Take notice how *wide* the damage is when a pass is made by the B29 using the 4k bombs.  They can be dropped further apart and get get just the same amount of devastation.  Remember as well that quantity does not mean "better" in terms of blast radius.  There is no substitute for mass.  This can be seen by dropping 1 each size of bomb on the city center, notice how far they all reach.  Two 1k bombs dropped .05 seconds apart do not equal a single 2k bomb.  Same goes for 2 500lb bombs vs a single 1k bomb.

Interesting.  Nonetheless the numbers I posted do seem to be consistently the number needed to kill a hanger using the object settings. A 500lb bomb will never kill a hangar set to take 562.6lbs and will always kill one set to take 562.5lbs.

Not surprising as 3600/6400 = 0,5625

There has to be some sort of timing going on that we also need to understand.

There are endless possibilities as to how a sim deals with multiple bombs dropped in short succession.

Does aces high count damage to an object two bombs that hit within a few feet and within 1/10 of a second as a single larger explosion?

Are they treated as separate events that have no relation to each other?

Is there some sort of time threshold?

Yes, thank you.  My argument has to do that a 2k bomb has a larger blast radius than 2 - 1,000lbs bomb.  Some dissagree with that and I was looking for clarification from the tech guys of AH.  I think the 2 bombs would have a larger concentration of damage in the core of the blast with the radius not extending out as far as the 2k bomb.

TS15pin presents in this thread a formula to calculate the radius of a blast.  As I read on, it seems that this formula was not formally validated.

A single 2000lb Mark 84 iron bomb will cause a bomb crater of 50ft (15.2m) wide 36ft (11.0m) deep.
A single 1000lb Mark 83 iron bomb will cause a bomb crater of 44ft (13.7m) wide and (5.5m) deep.

A 2000lb has 1035lbs of fragmentation and 945lbs of explosives.
A 1000lb has 555lbs of fragmentation and 445lbs of explosives.

Dropping two 1000lb bombs delivers the same fragmentation as a 2000lber but slightly less explosive impact.

The blast radius of two 1000lbs at the same time is less than a 2000, unless you stagger the release of the 1000lbs.

In Aces High, the same principle applies. As shown by the guys and the damage #'s, two 1000lbsers is 12800 and a single 2000lber is 11000. Makes sense to me.  Staggering your release on a larger targert will ensure a larger blast radius - and it would depend on what I was hitting. If it was a tank, I'd stagger my drop. If it was a hangar, I wouldn't stagger it.
