@@solus48Not to mention you have to be able to produce a million of these things per year as they are consumable items so the design has to be simple and cheap.
Keep in mind, these designs rely on Overdriven Detonation with layered explosives. Instead of pure HMX, the warhead would be filled with a core of Comp-B for example, with a thin outside layer of HMX or RDX. The RDX/HMX layer is initiated first, which shocks and compresses the Comp-B, putting its detonation velocity well over 10km/s. Jet velocity can very well be above 20km/s.
Can you share more or any sources? My understanding was that overdriven detonation was very short acting. I have seen a sentence or two in various papers about nitromethane compressed then detonated via a starting charge to it but never the results you mentioned. Would love to learn more!!

To achieve ring detonation from usual point detonator, try placing hollow/inert round dosc-like "lens" between point of detonation and cone tip of usual cone-shaped charge. That's one of main directions military shaped charges progress nowadays -- optimizing materials and shape of "lens"/explosive.
keep in mind that using a liner like beryllium can make the velocity of your jet increase because it's a much lighter atom, so it needs less kinectic energy to achieve the same velocity as a heavier atom like copper, so even though it is faster it doesn't necessarily have more kinectic energy, you should check that out because what you really want if the goal is to penetrate as much armour as possible is kinectic energy.
I was thinking along those lines - you want something that ablates easily but has high enough density to stay in liquid phase. NIF has done some experimentation in the fusion ignition space and copper doped beryllium seems like a good option here. just sayin'
@@razerbrosdynamics3917 Shaped charges don't last very long in the atmosphere. They cool down from their plasticized state and quickly lose speed due to drag. Shaped charges have existed since the 1930s. If they were useful for railguns, they would exist by now.

Hello, and thanks for a great video! Long time ago, I've seen a research paper about novel shaped charges. I don't think I can find it, and I'm sure it even exists in open acess (through if it does I'll post a link). But the design they ended up with, which has supposedly shown 20-50% higher practical penetration values, was as follows (also, english isn't my first language, so forgive me): A regular, non inverted shaped charge cone. Except the walls look "crincled". Cone consists of a small number (6-8) of wall "segments", each of them is a linear shaped charge. Upon detonation, jets from them converge. From top down point of view, the cone looks like a star, and from the side like a cone. Not sure if it's possible to simulate it in 2d, but anyway, thought you might find it interesting.
Thanks for sharing. I was thinking about shaped charge's and Molten copper just the other day weirdly enough. It's really neat being able to simulate this on a computer, Can you imagine having to physically make and test every design idea back in the day.

Even tho the jet might be very tiny in size and have low mass... At those speeds it will pretty much go straight trough anything i guess. And some MAD dedication you put into this! Really cool stuff!
Suggestion: for your simulation recordings, make a big ol' number in the corner counting the highest speed observed up to that point in the simulation, and gate the readout so it only considers the main jet and doesn't register any values from detonation fronts, backward jets, enclosed jets, etc. Make the number freeze for long enough that we can digest it before moving on to the next sim. Your current sims are interesting, but 1) not everyone understood to look at the little bold number in the upper left, nor how to read scientific notation; 2) the little bold number is constantly bouncing around all over the place so it's hard to tell when it reaches its maximum; 3) the maximum will always be during the interesting part of the sim, so your attention is diverted away; 4) the maximum is potentially contaminated with values coming from other parts of the system than the main jet as it just naively uses the entire simulation image, so could conceivably not reflect the speed of the jet, which is what we're interested in; 5) you switched between m/s and mm/s several times during your simulations, so it was confusing why the number was so much lower for your "ultimate" design.
The mass of a cylindrical charge is higher than a conical charge, reducing range and velocity which are key contributors to combat effectiveness. It makes sense they shaved off as much mass as they could lending us the current conical charges we typically see. Limpet mines that are placed were conical iirc though since they didnt need low mass to be effective.
This idea is around for quite some time afaik, but the issue was always to achieve the stability and symmetry of detonation and jet forming, as this is extremely sensitive to any irregularities. There were some interesting ideas like to shoot the high velocity jet thru a coil since it was supposed to be highly ionized and use this as EMP generator. But I am not aware that anyone has succeeded in practical implementation of this shaped charge geometry yet. Nevertheless I like your creative approach to the concept, perhaps it can be realized at some point.
I think that when trying to get those high speeds the geometry of the warhead, machining and powder consistency must be very precise, otherwise the charge will explode sideways and the jet will not form, as just small deviations will cause what in my field we would call a standing wave. That's probably why they are not used that much.
The jet is microscopic, it ain't going to damage anything. The beyond-armour effect need to be big enough for the thing to be worth the shot quite literally.
While the multi step detonations to make what are essentially dynamically formed light gas guns loom extremely impressive, I suspect they would require precision ignition to an unfeasably small margin of error. But the inverted cones were suprisingly effective, provided you can encase them in a sufficiently high hardness casing.
Never thought you would use DEAF KEV Invincible, but it is a welcome choice nonetheless. Edit September 17, 2024: Bruh you changed the background music
Someone else mentioned lenses. Seen plastic one near the base in rpg diagrams. It has to be a significant improvement to remove about a fifth of the warhead's payload.
Tbh should've done more penetration tests, that was cool to see, plus would give a better sense of comparison. Cool video though, I didn't know you could use Solidworks to design shaped charges.
There are probably a lot of solutions in here that are correct, but unstable. The smallest changes with machining, explosive packing, and detonation may not produce an actual jet. If I drop a quarter edge down, how many times does it actually land on the edge- very few if any out of thousands of attempts. Very cool video. I've always wanted to see a simulation of a shaped charge- fascinating stuff
If you lined it with Lithium Deuteride/Tritide and collided it with a jet in the opposite direction it may well have enough energy to trigger a fusion reaction. I have no idea of how much of a reaction but those speed may be sufficuent to overcome the Coulomb barrier for Deuterium and very likely for Tritium. It would be fun to do some experiments.
That is how the Nazi experimental mini nukes worked (if you believe in historical conspiracies ). Two opposing Lithium Deuteride shaped charges colliding initiate a small fission reaction liberating neutrons, those neutrons are then used to bombard a sub-critical mass of uranium inducing a fusion reaction. So a Fusion-> Fission bomb instead of the Fission-> Fusion bombs that are common today. Most debunk the idea by saying the shaped charge fission could never happen, this video makes me think otherwise.
@@squidwardfromua You really couldn't, best you could do is fit like 8 or more blasting caps around the ring, but achieving a perfect spherical Detonation is very difficult unless the explosive is Laser or Electrically Initiated an has a small mass.
