Really odd idea


I have a knack for cost effectiveness, but here it goes. I have an idea for an explosive consisting of compressed air, and a powdered explosive or fuel. Yeah.

Do a search for "fuel-air bomb", and realize that hyperbaric bombs are almost exclusively based on that very principle.

I know what a fuel air bomb is. But sometimes the dispersion of the fuel is better said than done.

Or just soak your fuel with LIQUID air.

Rapopart’s Rules for critical commentary:

1. Attempt to re-express your target’s position so clearly, vividly and fairly that your target says: “Thanks, I wish I’d thought of putting it that way.”
2. List any points of agreement (especially if they are not matters of general or widespread agreement).
3. Mention anything you have learned from your target.
4. Only then are you permitted to say so much as a word of rebuttal or criticism.

I had an idea for an 'active ' explosive after seeing a grain silo explode on TV.

Some dust, cylinder of compressed O2, spark plug.

you would need some form of containment for two reasons:

to prevent excessive dilution
to constrain, temporarily, the reaction.

You need a Silo.

Now I expect in the case of a Fuel Air thingie, the expanding gas is constrained by the surrounding atmosphere compressing, and dilution is avoided by oversaturation.

What will be your silo.

Hypothetically :)

LOx explosives, liquid oxygen explosives made on blast site by mixing liquid O2 with fuels (solids or liquids)...

A Silo perhaps ?

It was all just an idea, and never made it beyond theory.

I'm interested in a similar concept, except something more along the lines of a potent liquid fuel under pressure with an oxidizing gas, or perhaps vice versa.

I had been wondering how nitromethane slurry and acetylene might go, but based on what I've read I'm thinking that the compression of nitromethane might yield explosive results in a distinctly more abrupt manner than I'd really appreciate.

On the other hand I then wondering if putting Xylene or Toluene under pressure of something like Acetaldehyde or another explosive gas might also yield interesting results.

And this then lead me to yet another line of question.... Do you think it would be possible to nitrate Xylene or Toluene by putting them under pressure in a sealed container of Nitric oxide gasses, or some similar process? I doubt it would be efficient in terms of the chemicals involved, but reaching trinitrotoluene as from plain old toluene sounds much more obnoxious than I was expecting... sorry if this has gotten a bit off topic.

Woah, I did a double take when I saw this. Welcome back LG!

Mixing liquid/gaseaous oxydiser and fuel is in the line of rocketry technology.

Nitromethane too dangerous when compressed...just like acetylen by the way (it is endothermic material and can detonate back to its elements C and H2).

Many substances or stable mixes turn to be unstable once compressed...a typical example is H2/O2 mix what is stable in a glass container...when increasing pressure at ambiant T°, radicalar chain reaction at the glass surface becomes significant and suddently it deflagrates the all mix.

Mix of fuels like aromatics and N2O4 can be propergolic or hypergolic...some are detonable by shock...see Sprengel explosives of the class Panclastites...

The problem with using air is that it is a poor oxidizer. 77% of it is inert gas, by weight. The problem with using gases in general is that they are not very dense, so the explosions are weak (compared to solid and liquid explosives) and have little brisance. They are good for making long pressure waves but lack the shattering power of other explosives. The density of CHNO explosives are typically between 1 and 2g/cc. The density of air is 0.0012g/cc. Compressing it will help but you'd have to get it to a little over 12,000 PSI to approach 1g/cc.

Also keep in mind that using a liquid fuel with a gaseous oxidizer might cause problems with keeping the two mixed. Ideally both components are gases, like an oxy-acetylene or oxy-hydrogen balloon.

Not a chance I hate heights! there is no way to get me out the plane so making a bomb out of my parts would be pointless :D Great to see your still keeping the bars happy A lol :P

If mine is anything to go by I would be more scared of MOAB! Dads a pussycat in comparison
