NEW LSC DESIGN

[AfterRain]

<img src="http://free.prohosting.com/~octsky10/sc.gif" alt=" - " />

I was thinking by having 2 upside down v's at an angel each, when then came down they'd create a bigger cut, such when you ax a tree you come in from an angel on top and bottom to create a v type cut. Would this work?

Sorry if i put this in thewrong space, i think sc are a tool, so i put it here.move if needed, but was not to sure. thanks
now i look at that pic i made, it does not show what i had in mind, see been up for lil over 24 hrs, so i tired and got sore eyes, sorry...

The drawing looks a little retarded <img border="0" title="" alt="[Wink]" src="wink.gif" /> , but I get the idea.

There's a device called a "fracture strip" that uses two opposing strips of PBX mounted on a plastic strip. The two PBX charges are at slight angles to each other and, when exploded, the shock from the two charges intersect inside of the target, causing it to fracture. It doesn't cut through the metal like an LSC does, but it does the same thing, severe the metal in two. It also uses a lot less explosive.

Not to put a damper on your creativity, but are you trying to reinvent the wheel? The masters use a single chevron-shaped linerl. They must do it for a reason.

Also, ALL CAPS TYPE is highly annoying. Please don't do it in the future.

shaped charges work because of the monroe(sp?) effect. and the best way to harness it is the typical SC/LSC

edit: fixed pic. why the hell is HTML off?!?!

basically you need as many explosive waves to come together in a constructive interaction. like light waves...two waves can be added if shot at the same time or can cancel each other out if shot half a wavelength apart (i know shockwaves are longitudinal but transverse waves are easier to imagine). basically it works on the principal of vector addition as far as i know. the vectors of the shockwaves add together to make a larger shockwave. think that makes sense anyways....i'm tired...
the first one is an interesting idea.
heres some links for shaped charges and munroe effect originally from tabletop tactics or somthing...copy and paste to your browser...

The metal is never molten in a SC.

[AfterRain]

No im not trying to reinvent the wheel, it was a idea i had while reading some info on the sc. so it has the same effect,thats cool... thanks.

[nbk2000]

The metal is ALWAYS liquified in a proper SC.

They're not 3 seperate designs. It's 3 stages in the detonation of the charge that he's attempting to illustrate.

However, if it supposed to end up like #3, then you've just achieved the same thing every other LSC on the planet does, only with more effort and less effect.

Afterrain, I hope you're not thinking that my description of a fracture strip is somehow similar to, and endorsing your idea, because it's not.

Don't innovate, imitate. It's much easier. Especially when you don't know what you're doing yet.

Maddog555, HTML is off for a reason that you don't need to know. Learn UBB Code. Does the same thing (for the most part).

[Anthony]

From the information I have read on the subject, SC liners do not liquify, or turn to dust, the should stay as one piece. Like the experiment where prefragmented liners were fired into tanks of water. The liner simply gains more energy than is needed to totally deform it, making it act like a liquid when it encounters an object.

[AfterRain]

That picture i made, does not at all , show what i was tryin' to show, other the its got the 2 v's....

NBK, i wasn't at this time trying to play wit the stuff, i was justing read some info on them, But do you know where i can read up more on them with detailed information , such as whats the space between target and sc would be for different targets, and explosives to use too.. And does any one have some good chemistry sites, im trying to expand my knowledge into more of the explosives section... :)

10Mb download. The full file is included in the "Explosives_Forum" 1999 PDF archive that I made a long time ago. It's on the FTP. A lilltle looking would have found it. :rolleyes:

[ST]

The liner acts like a "liquid" for the same reason glaciers flow and the continents drift, immense pressure, but none of these are truely liquified.

[nbk2000]

Ice flows because of immense pressures, true. But ice isn't metal. And it's not doing so in the space of milliseconds either.

When a copper cone (or angle) is inverted in milliseconds, it turns white hot and liquifies. Just take a piece of coat hanger wire and bend it back and forth a bit. It soon gets too hot to touch.

Now, if you can do that by hand without working up a sweat, imagine doing it in a few milliseconds with a piece of metal too stiff to do by hand using a chunk of high explosive that explodes with thousands of degrees of heat. Hmmm?

Jesus, there's even pictures of this happening. One was just recently posted. Look for it.

[kingspaz]

further evidence for liquifaction of the liner is inside tanks which have been hit by shaped charges. the inside is often splattered with splats of copper as the jet has penetrated through the hull and dispersed upon impacting the irregular contents.

[Mr Cool]

...and after a certain distance (varies depending on construction of SC), the jet begins to break up into droplets.
