Does Size Matter? | Explosive Shaped Charge Comparison

Explosive Shaped Charges are one of the most fascinating items we work with here at Ordnance Lab. Explosive shaped charges are very simple, yet are able to focus the incredible power of an explosion on a metal or composite liner, and send it traveling at blistering velocities to penetrate even the hardest of substances. The concept of an explosive shaped charge is simple, but the method of optimizing their performance is not so easy. Many factors go into play to make the explosive shaped charge get the maximum penetration possible. In this video, we do a simple study of the relationship of the explosive shaped charge liner diameter and it's stand-off distance to the target. We measure the penetration of difference stand-off distances to see what is the best distance from the shaped charge and the target.

It's been a busy few months for us! We had to take care of some explosive business contracts that keep the lights on in the lab. If only we had a sugar daddy to fund our wild experiments without having to to pony up the sugar. So what would our amazing audience like to see tested this year? Leave your suggestions in the comments and we will see if it is feasible.

Some satisfying explosions, no doubt. You are also right up against the "liner angle" issue (like this needs more complication). Which has the added issue of "how 'thin' a wedge" of explosive will still deflagrate explosively. And, if we really wanted to confused the RCMP watching, we could ramble on about the loci of elliptical paraballoids, which would want either 3d milled or printed liners. It's still cool content.

Try 1.2-1.5 Also would be interesting to see .6-.8. That way could the cone help penetrate as its forming to the absolute peak ? Another thing o have found is that straight cone designs are less efficient . This is due to the explosions shockwave catching up and causing turbulence as the jet forms . Try a curved outwards design. Similar to how a air horn curves away . I don’t remember the exact curve angle but there’s data on it via a government study from the 1960s . I believe the rpg-7 standard HEAT warhead has a similar form. As does the Javelin tandem warhead . Easy way to make the liner without spending a small fortune is to 3d print the form and coat it with a powdered metal paint. Then electro plate the form . You can run multiple liners in a plastic bin/s with the same power supply . Great to see you guys back :)

@geodkyt 3 ай бұрын

I'm such a test dork I just envisioned a simple test rig to maximize granularity, interchangabikity for production efficiency, and simplicity, using PVC pipe (because reasonably stiff, albeit frangible, but low sectional density to reduce hazard when it fragments), charges and slugs chosen to fit snugky but still dlie inside the pipe, and plastic pegs to ensure a fixed (but easily selectible by the magic of "drill a series of precisely spaced holes at whatever desired distance") stand off, with a setup you can lay on its side in a narrow trench to contain fragments (and hopefully the steel slug). Of course, this presumes you arenusing an explosibe that is solid (or at least fully constrained) at ambient test temps and 1g acceleration... otherwise you have to bore holes and set the rig up vertically... Yes, I'm a nerd who enjoys figuring equipment tests that are safe, repeatable, usefully accurate, and as cost-efficient as practical. 😂

And entertainment lol stay safe and keep the good work going thanks for all your hard work and dedication

Video idea! How small can a shaped charge get..can you perhaps make a few shaped charges of different size taking into account the liner thinckness and standoff so its in scale...i would love to see how the penetration scales and how small a shaped charge can get...i mean lets see how small it can get im talking coin sizes and maybe even smaller...Gread videos, love u guys!
