Linear shaped charge

This videos was meant to show that a shaped charge can be made with ANNM. There´s lot to improve in this device but it give us a clue about the effectiveness of ANNM for shaped charges applications.

For shaped charges the only thing that matters is the VoD and if I add some Al powder I will get more power but lower VoD and for shaped charges it will not help.

The case is a PVC tube and the liner is a Al corner indeed.

hey man, i was thinking..

maybe its a bit late but im reading a lot of shaped charges and explosive welding and ..i think that maybe you should use a standoff between the charge and target, when the charge is too close to the target, the jet hasnt enougth time to form the penetrator slug.( i saw that in "the detonators", that serial of discovery channel)

You are right, but as this was a wood target the jet formed thru the wood, but a steel target without the standoff can result in a fail. With a standoff, in this target, the result would be a cleaner cut.

nice, what was the structure it was attached to?

[datzfast]

can you cut down trees with it

I tried a12 in x 2in pvc tube with a 3/4 in plastic 90 degree angle lenghthwise inside the pvc, then filled pvc with bullseye reloading powder (basically off the shelf TNT with 21000 fps velocity) and kicked it off with AP. The 1 in steel plate it was set against was shatterred into a hundred pieces

Try this on metal. You can't tell if a jet formed on wood.

Don't forget to put it at an angle next time... :D .

You gotta try that thing on a concrete pole to see if it can slice through concrete and rebar...I would be surpirsed if it did.

100% correct. and i know u, i sent u an email, read it please.
