See that fragmentation coil there. It is limiting the fragment killing radius to few meters.

Here is some calculation for the same grenade in ideal conditions without the fragmentation coil. 185g of Comp-B should be enough to give 2g fragment 480m/s speed at 100m.

The purpose of the fragmentation coil on a hand grenade is to provide the fragments, not to limit the fragmentation range in some way.

Your link to the Gurney equation covers the fragmentation part of the picture theoretically but note that the calc is per fragment, and there are a lot of 2g fragments in a fragmentation coil. The 5m statistic is just that; it is probable that enough frags will hit you to kill you at under 5m, injure you badly at under 15m, but might injure you to some degree a lot further out than that. Last time I threw a hand grenade I put something solid between me and the bang. Much safer than statistics..

The Gurney equation doesn't cover blast effect.

I brought up this thread with fellow EOD/armament personnel at work, showing replies of TD regarding bombs. Verdict: stop talking about things you know a squat of. After looking at the radiuses in IL-2 questions were: what is this based on? How do you define destruction range? What damage is considered? Which formula was used to get such results, what parameters are taken into consideration..and many more. You might know the inner works of IL-2 etc. but seemingly there is not a single guy in the team knowing more than theoretical things, nothing about RL application of explosives. Or am I wrong?

In IL-2 the bombs of ALL nations could use a closer check to determine how they are modelled. This has nothing to do with blue or red, I am beyond that crap. If there is an error or discrenpacy in data then a check is not a bad thing..I think no-one would disagree with that?

I rest my case here. It is useless to argue.

Fully agreed. It is a question of credibility. I think that this "problem" could be fixed very quickly, if data are available.

In theory, I agree. But the explosive experts probably don’t know a squat of simulation. The very same argument can be used about aerodynamics. For example, I’m not convinced at how the trim works in Il2. In real life it has mainly to do with stick forces, that can’t be modelled at all. I understand that to work efficiently with a sim has its own rules and requires its own competency.
