We started with indirect fire weapon systems and 3D printed claymores. So this obviously was the next step in our evolution of projects. Now that we have a solid amount of data collected from these tests, we can collaborated with DNS creations in creating some wild 3D printed direct fire ordnance as well as other fun devices.
Two things that may help from my own attempts at making similar devices. 1. use the ignition of the rocket engine to light off the ejection charge. this will give the rocket more speed before it leaves the tube. And 2 give your launcher a vented back plate, the hobby rocket engines you are using don't have the thrust you need for a pure recoil less gun. hope this helps!
Tube launched rockets are more or less rare in civilian applications but most of them have folding fins that help with keeping them straight. There is also the option to give them a nozzle like a gyrojet and there are surprisingly good videos with instructions on how to make them on YT. But let’s be serious skip the unguided rockets and go directly to the laser guided Hellfire:) Nice video as always.
I can't stress how much fun it was to make this video. Getting to test out legit 3d printed rocket launchers is on a whole new level of awesome. I'm so ready for the next generation launcher Steve and Dan Cook up.
Wonder if rifling is hindering its accuracy rather than helping. As Taofledermaus has shown, adding spin stabilization isn't always better. Great prototypes!
@@DandSCreations But the RPG spin is not induced by a rifled barrel but by its deployed fins and the lugs that the propellent gasses vent through. The majority of its stabilization is drag based.
@@Matt-dc8lp yes you're correct but as in trying to keep the munition all 3D printed, folding fins are not a viable option. The recoilless charge design had flaws, we will rework it to get an enhanced muzzle velocity this will help substantially.
Reminds me of the Deterrence Dispensed CANzerfaust that's being developed, except that one shots soft drink cans in two configurations. Shaped charges are always fun as well, unless you on the receiving end of a copper jet. Very cool, potentially DIY-able stuff always gets a thumbs up from me.
@@Tunkkis like, is the can itself loaded with powder/propellant or whatever? Or is it like a muzzleloader where the powder is added and the projectile is just an inert object propelled by the gas from the explosion of the powder?
It was an awesome time filming with y'all. Looking forward to mark 2B. We have some serious performance upgrades planned as well as dabbling in smart munitions next :-)
Excellent work 👍👍 Have you guys considered angled jets or jet deflector fins to create spin on the rounds? I realise that they have to be really quite precise to achieve the desired spin but on a 3d printer it should be simple enough to create a nozzle that would survive long enough to create the spin no?
I'm thinking something like the gyrojet rounds. Obviously the burn speed is an issue due to the erosion of the nozzle but given the slower speed of the projectile it could be done, even crudely.
While I wouldn’t say it’s the first 3d printed rocket launcher as my fliegerfaust is about 70-80% 3d printed in steel, made last year and there’s some 3d printed plastic builds that predate mine several years however it was excellent to watch the video , useful data and I’d say a job well done. If they need help with their rocket motor I’m more then happy to help with advice as my motors use a similar fuel
@@chemistryofquestionablequa6252 I’d definitely be down but unfortunately just a bit far away from me. I hope to get my FEL when I can afford to purchase some land however with prices at the moment has delayed that considerably. I’m looking for a local FEL to help make our rockets more spicy
the printer you are using has some under-extrusion issues - either clean + re-seat the print nozzle, use a slightly higher temp and/or clamp down more pressure on the spring pushing the extruder wheel against the filament. I also recommend moving to a nozzle that is at least .6 or even 1.0 rather than the standard .4. (i ran a 3d print shop for 2.5 years) + 2 more hobby printing - so trust me :D
@@brucebaxter6923 maybe, but this reminds me more of an issue i saw with a cr10 i had a few years back, the bowden tube kept backing out and creeping away from the metal hotend, causing a gap and friction in the throat + a grainy filament that then clogs it up a bit more - combined with the underpowered cr10 extruder and/or worn out gear teeth. and yeah @D&S_Creations - it really was almost exclusively the greenish filament used on the small rockets. if it was an old filament that had absorbed a lot of water, it would also lead to poorer print quality
@@DandSCreations yeah, it really was almost exclusively the greenish filament used on the small rockets. possibly it was an old filament that had absorbed a lot of water, it would also lead to poorer print quality ontop of what i listed above and in my reply below to Bruce Baxter
@@cytherina For sure. It definitely could be that. Personally I have found those issues to be reduced by slowing down and running hotter nozzle with less cooling fan.
I 3d printed replacement igniters for a LAW along with mounts to install a 10mm barrel. This was to make it non-NFA. I then built 10mm rockets that burn out inside the barrel length like the real thing. I'm currently working on getting the rockets to a higher velocity. Right now they are around 400fps. The first test can be seen here: ruclips.net/video/rhQ8cSFAM2M/видео.html
why has nobody converted this idea into a 3D printed mortar? all you'd have to carry is a 3D printed abs+metal tube your propellant charge and your 3D printed rounds. they'd be incredibly light and easier to carry than classic mortars and could be absolutely deadly using something like ammonal to throw shrapnel or BBs
So glad to see your videos everytime they're uploaded. You guys are great! Not to mention educational. Keep it up, and may the algorithm always be in your favor! (also, more hellcannon please)
such an awesome 3d printed launching system, can't wait for the extra content delivered on Utreon hopefully explaining a bit more about the impact fuse and internal fuse mechanism
I think Jairus wins the bragging rights for first 3d printed launcher for his working SPNKR video game rocket launcher re-creation, but you get the creds for a more authentic launch mechanism and for having actual explosives in the rockets...
Oddly enough, The King of Random made a potato cannon that fired explosive warheads. This was while Grant was still alive. It would probably be really easy to combine thier tech and match what these guys did
You should test those against various types of targets: - Solid steel armour - Reactive armour - Army trucks - Troop transport vehicles - Russian oligarchs
You guys, honestly. I've just subscribed today and this is already the second video where you are making very polically incorrect remarks. That is so refreshing and I love it to shreds...or shrapnel xD Please don't stop.
This is seriously cool 👍 excellent work guys 👍 that's also surprisingly accurate given the fact that it didn't have a ton of R&D and factory made rounds.
Looks like your CG and CT( center of thrust) are off. Also powdered copper won't work you need copper flashing like for roofing depending on size, bigger = thicker. There are formulas on wikipedia and if youre clever you can put in a test stand to measure. Don't ask how I know but that was the first problems when doing this. There are ALOT of variables, especially with the rocket getting lighter as it burns, the back blast charge and mass to do a boosted launch, the time fuses the det fuse etc etc. really good for a first try!
@@deathninja16 we are trying to keep it 3D printed. These were the first two firings of this rocket we've ever done. Have to start somewhere, collect data, make changes. The concept fully works and now we know what needs to change. (Redesign the recoilless cartridge, more of a launch charge, less nose heavy, more fin area)
For a tube launch system. . . Bell shaped engine porting(cardboard with fiberglass cover, cheap and easy)= increased & controlled thrust+ smooth bore + tight tube+ fold flat launch deployed fins (PFTE works great!) = stabilization and a true linear flight path! 🚀 Faster speed not needed! 🚀 Three fins is best but two curved ones will work if you get them positioned correctly and the bonus for using just two is increased speed! 🚀 Two small pop out canard fins just behind the warhead will slow the spin and produce even greater stabilization. Without a gyro or a guidance system a proper fin design is a must and will induce spin stabilization. . . From an old Rocketeer!🚀 You Guys ROCK!
Awesome shaped charge try! That light green tint to the explosion was sweet. As for describing explosions, I always say it's like a full body punch that shakes all your organs, at least at close range.
For the smaller rockets, I would not use "White Lightning" propellant or propellants that have coloring agents that have a tendency to absorb moisture (ie Reds and Greens). They have a tendency to become harder to ignite as the motor ages. "Blue Thunder" is a safe bet, so is Fast Jack.
4:45 Lol imagine if a bunch of people that have 3-D printers get tired of the government pushing them around and forcing them to do stuff and they start making stuff like this lol

I can't stress the amount of AWESOMENESS this is!!!! Awesome job guys!!! Just a really FUN video, Let's hope YT demi-gods don't take this down too. GREAT VIDEO GUYS!!!!!!
Something I found out about lead / zinc air rifle pellets; try the diablo effect, a certain set of rules apply to diablo-shaped lead pellets, which forces the object to follow a straighter path with or without rifling.
That looked like a lot of fun. I played around with model rockets when I was young, and always wished that I could have had the ability to put a warhead in one to have a nice fireworks effect. I had no desire to hurt anyone, but definitely wanted to blow up a balsa wood rocket and make a boom. I am looking forward to seeing what else you guys can do with your 3-D printing. 👍
Easy stability test - find your rockets center of mass, tie a string around that point that is several feet long. Spin it around like a lasso. If the rocket is stable - it will stay forward during the spin. If unstable it will spin facing backwards
Pro tip: Use an balloon filled with Brown's Gas behind the rocket and fuse. That detonation should launch the projectile fast enough before the rocket stage kicks in. Potentially also use an HHO balloon and pull-string fuse, detonate the balloon, and have the pull string fire off the rocket motor and activate the warhead. Not really hard stuff, but you all just need a way to achieve higher initial velocity.

Yea, in this case simpler might be better. For example the at4 is smoothbore.
Thats the same reason why most tank barrels are smoothbore, spinning something with fins dosent always help with stability, it usually makes it worse.

Easy stability test - find your rockets center of mass, tie a string around that point that is several feet long. Spin it around like a lasso. If the rocket is stable - it will stay forward during the spin. If unstable it will spin facing backwards

This video should be retitled: "Building shoulder-fire rockets is hard!"
Smells like freedom up in here.
The movie "The Losers" made a rocket launcher with duct tape and PVC.
These boys accepted the challenge...
that land nav roast was smokin.
idea: add folding wings like that of the RPG 7 or panzerfaust on the rocket for more stability
You mean PG-7?
Version 20 of this will take out an Abrams
Can't wait for part 2.
Pro tip: Use an balloon filled with Brown's Gas behind the rocket and fuse. That detonation should launch the projectile fast enough before the rocket stage kicks in. Potentially also use an HHO balloon and pull-string fuse, detonate the balloon, and have the pull string fire off the rocket motor and activate the warhead. Not really hard stuff, but you all just need a way to achieve higher initial velocity.
im sure a more compact version for practical use could be made with the inclusion of some metal components so pressures can be increased
