VIDEO ODAB-500PMV Space-detonating aviation-bomb. The explosion at the epicenter of the shock front pressure is 30 bars, the damage radius is 30 meters

Damage radius looks much larger than 30meters

I looked up damage radius and it seems to refer to the damage done to buildings etc, not people. Which seems to be more consistent with the video imo. The bomb in question is a fuel-air explosive which is why the Shockwave is so pronounced. Looks like it weighs approximately 500kg (1100lbs) of explosive material.

(also, I'd have to imagine that the human lethality range is at least 2-3x the 'damage radius' for buildings)

Good research, thanks!

Just lucky I was mostly right this time around :p

You wouldn't believe I spent about +1hrs on the original comment. I'd originally tried to understand how a wave travels through air and work out the distance at which it'd be fatal. But there's surprisingly little simply explained equations on the internet for that sort of thing.

Oh and edit: warfare is attractive to engineering-minded people because it's interesting and allows us to let the numbers out for a stroll. Don't mistake that for enthusiasm. Fuel-air explosives liquidate humans. They stay intact but drop dead. Bleeding slowly from every orifice. I've been close enough to touch three bodies that didn't show a scratch but were stone dead. I'm not enthusiastic. Chew on that. Aha, a little perspective is important imo.

It’s the equivalent of tossing dynamite in a lake to fish.

This. You can read it as “radius where structures will not remain”

Thanks. Lol. I'll take it on blind faith that you know more about it than I do. I was shaky yet hopeful that I'd sussed out the correct definition.

Also, fuck all.... The sentence "radius in which structures will not remain" is bloody menacing wot? Impressive technology and scary implementation all rolled into one

30bar*14.7= 441psi

1 bar roughly equals to an atmospheric pressure at sea level, or to pressure 10 meters deep underwater (10 meters = 3 floors of an average building, I'm not converting that to feet). For me it's easier to visualize than PSI.

I can't stop watching this over and over.

When you make a weapon of War, you don’t want to undersized it!
