The reason your torpedo shaped rockets are no longer straight when they exit the tube is because they don't have enough speed for the fins to stabilize them at a point when the rocket motor is still pushing. You either have to have motors which push for a shorter period of time or with more force. Possibly both. I would suggest you use G74 or G80 Enerjet/Aerotech rocket motors.
Now that you've made a weapon from the game, it would be cool to see you make your own custom halo weapon! Maybe it could be a halo-style grenade launcher?
Being a diehard Halo fan, this series has made me so happy. Whenever I look at my framed copy of those blueprints, I am just blown away at how you brought that launcher into the real world.
By far one of my favorite RUclips series ever made. I have no idea how Jarius isn't a huge RUclips maker by now. I would love to see more collaboration with people like Adam savage (tested), fireball tool, Alec Steele, and plenty of others. Everything he makes is so cool and functions amazingly. But the build process and the way its presented makes it all feel fun and attainable/doable! Definitely sharing these videos because I need more.
Some of the Estes model rocket engines have an ejection burst tip that is meant to separate the model rocket's cone top from the body in order to deploy a parachute or other gimmick. If the motors he's using had a variant with the ejection tip, those could be used to create a simulated explosion with confetti, or rigged to detonate something actually explosive, such as a small firework in the head. I know those can ignite stuff too; I burnt the parachute of one of my model rockets when it was improperly stuffed and the ejection explosive set it on fire even as it deployed.
I literally said wow! out load when you guys started shooting the rockets! So much improvement from the last time, these look like legit anti tank weapons without the boom
Hey! So exciting to see more of your epic work! I am sorry that I had to stop supporting you on Patreon for a while... hopefully I can start supporting you again soon!
Awesome to see the launcher in motion as usual. For the fold out fin rocket I couldn't help but think about ways to fix the issues. I think using multiple elastic bands will pretty much always mean they deploy at different speeds. RPGs with fins seem to use small mousetrap style coiled springs to fold them out, so that might provide a little more consistency. I wonder if a moving sleeve might also work, something with a bit of an airbrake on it that pulls it back along the body folding all of the fins out at the same time and then folding down the airbrake bits at the end of travel. Again, an awesome video, it's so cool seeing this thing work.
This project does not fail to impress, and seeing the excitement of everyone shooting it even more so proves that. Looking forward to seeing whatever tweaks can be done to improve the rockets more so
I feel like the Halo rockets would benefit from a sabot. That way you have contact along the whole length of the rocket instead of just the fins that might bend or deform.
A few things to try: - HJ-8 style fins to keep the fold-out forces relatively low during low speed flight. - Use fold-out fins mid-body with strong springs and static rear fins for tightened tube stability. Mid body fins will cause less disruption in the rocket’s orientation when folding out at different rates. - Increase the rocket motor strength and size to improve the spin stabilization rate. Hopefully rockets don’t spontaneously disassemble. Excellent work as always!
Awesome work! Can't believe I'm just seeing this, we got irl spankr irl dmr irl shotgun irl magnum irl ma5 and irl warthog at this point the military should start contracting halo fans lmao
I believe it is important to get the rocket up to a stable velocity as soon as possible, which is why military rocket launchers often have an initial booster before a sustainer motor.
This could honestly with some work be a viable system for an anti tank rocket system. For real. Make some removable pods like the game and bam. It's ready for the field.
If you want to go bigger or more inertial thrust, they make 29mm motors that have higher impulse if you get your L1 rocketry certification. Plus, you can get "sparky" motors that would look amazing out of this thing. That may be a worthwhile series of vids, designing and making/launching a L1 cert rocket and getting the cert then using the upgraded motors to see the difference.
Considering your experience with rockets and fantasy creations, how do you fancy taking a crack at the Bolter from Warhammer 40k? You could base the firing mechanism of of the Gyrojet and try to improve upon the ammunition design by adding features such as fins or a sabot. Its been a dream of mine to see the Mighty Bolter brought into reality but I lack the mind to create it. Hope you see this Jairus.
I really can't wait to see how you'll somehow improve on this EVEN MORE. After a certain point you're going to start being offered government contracts lol. I personally would love to see you make a second tube so it can actually be reloaded!
Rifling is actual detrimental to fin stabilized rockets and is the cause of your corkscrew effect. Your best option is actually to work on the flight of the projectile itself. As well as a discarding sabot to keep the rocket from bouncing down the sides of the tube.
If you do another redesign of the rockets, I'd recommend a primary booster charge backed with a heavy wad to launch it from the tube before igniting the booster charge. This allows a significantly larger rocket motor without burning the user. Just be aware that that's getting into dangerous backblast territory.
Your rockets are no longer straight when they exist the tube because they are not fast enough for inertia and the effects of the fins to stabilize them. Try using G74 or G80 rocket motors from Aerotech / Enerjet. Also make your 'forward fins' smaller, just enough to hold the rocket body at the center of the tube.
Tip to improve the design: tighten up the coil on that inner lining. It'll increase the amount of rifling inside the launcher, and thus make the rockets have a greater spin and will fly more true. bonus tip: for content sake, and for theatrics, on some of the rocket heads, add holes that angle from the butt of the rocket into the head , then put some elemental sodium, potassium or magnesium in the front part of the rocket before applying the head onto the body. Then shoot at water. The holes allow water to enter the rocket, and the alkali metal (sodium, potassium etc) will then explode on contact with the water.
Thought about putting a thicker wall metal sleeve insert with a plug on the end so the rocket can build more pressure? I suppose you would have to design another rocket model if you would want to go that route. At that point, it's less of a recoilless rifle and more of a rifle using nerdy rocket propelled ammunition
Wow. This video really made me want to be a RUclipsr lol. What a life you guys have. Experiences I can only dream of. Good luck, man. Keep the vids coming.
In future iterations of the rocket if possible you should implement a tandem charge for the rocket. Because modern rocket launchers work by essentially essentially setting a small charge behind the rocket to project it out of the end of the tube and then the rocket ignites a safe distance away from the person firing it. That may increase accuracy as you don't have as much interference from the tube at the moment of Ignition and at the moment of Ignition all of the fins have already deployed. Also maybe think of removing the rifling as rockets don't really require rifling due to the fins. From my understanding there's 3 types of stabilization and stabilization in flight Fin, spin, and whatever type of stabilization of the Diabolo is. But adding more doesn't make them more stable. Rifling adds only as much stability as there is rifling in the barrel and as soon as it leaves the barrel it Can only lose stability. Fin stabilization has stability all the way through flight along with diabolo. Although diabolos require projectiles to be in specific shapes and formations and are most often used on shotgun slugs and air rifles. Where a fin stabilization is what a what a variety of large caliber munitions from tank cannons to missiles used today. And maintains accuracy over much larger distances.
Hopefully with that slow-mo shots you can get the systems working as intended. Also those ones that are tilting so very slightly, could it be the internals are heating up causing warp and allowing some play with the motors? As the rest seems good, but it seems that only the motor moves slightly, or the the cone to direct the flow is distorting causing the problem.
Just had another thought, what if you got a really long acrylic (transparent ) barrel, and then set up a high speed camera, then launched a rocket through the tube and determine by position over time when the rocket hits optimal launch velocity within the back the length of the tube, then you could mark that length and use that as your barrel length.
#AlternateDesignIdea: Put a launching charge at the back of the rocket that ignites the rocket motor. It's basically a cut down shotgun shell (or a "Shorty" shell) but it's lightly attached to the business end of the rocket motor, has no shot or wadding, and it has just enough gun powder to ballistically launch the rocket several feet out of the launcher before the motor ignites. I'd recommend slower burning rifle cartridge powder so you aren't blowing the back of the rocket off. Each rocket can be set into a tube that has an endcap with vent holes or vent slots on the back of the endcap. This would give the rocket something to thrust against, getting it out of the tube faster, giving it a MUCH higher terminal velocity, and therefore get you longer range and it SHOULD actually give you BETTER accuracy, due to the air pressure on the thing being higher which SHOULD cause the spin stabilization and the fins to work better. Then all you have to do to reload is pull the rocket reload tubes out of the launcher and shove another one in there. I'm pretty sure that's how they work in game, but I haven't seen it in a while, so I don't truly know. Oh... and if you get the powder charge right... it'll get the rocket out several feet, so that you are no longer catching flaming rocket exhaust to the face. :-)
Canned air, like what you use to clean out computers, will also produce Mach diamonds when you spray it full blast out of the straw thing it comes with. I discovered this while setting up a high speed schlieren system at work a few months ago because we use canned air to check that the schlieren setup is setup correctly.
So glad you got to experience this gratifying payoff for such an amazing project that we all know you've put countless hours of work into. Keep doing phenomenal things and inspiring people!
You're having an issue with drag from the rear fins. The front of the rocket is encountering less resistance once it leaves the barrel. But the back is still in the barrel creating vibrations and drag. Use a SmoothBore barrel with smaller folding fins; preferably housed in the rocket to where the rocket body is smooth. This is the very much same issue with bullets and why very long bullets (the projectile, not the case) is a very bad idea. Also experiment with how much twist the fins should be. Too much twist will spin your rocket out of control and tumble in mid air.

I know this is literally the meme but I've had 3 raid sponsored videos in a row now. completely different genres and stuff
You could make a 2 piece rocket with opposite rotating ends (using little fins). Then you could connect by some sort of bearing. Maybe 🤔
A raid commercial is now the new rickroll
The reason your torpedo shaped rockets are no longer straight when they exit the tube is because they don't have enough speed for the fins to stabilize them at a point when the rocket motor is still pushing. You either have to have motors which push for a shorter period of time or with more force. Possibly both. I would suggest you use G74 or G80 Enerjet/Aerotech rocket motors.

This was SO MUCH FUN! Thank you for letting us shoot your insane Rocket Launcher. Let’s do another Collab soon!
We definitely need to do something like this again, or combine our powers and build something!!
Yes! More collab = more better
You guys are awesome!! I love Impact Props videos!
ngl kinda bricked up rn ... gonna go play some halo
IMPACT PROPS I TRIED TO MAKE UR MASTER CHEIF SUIT A LONG TIME AGO BUT FAILED
Seeing it finished in all of its glory its hard to believe you actually built it from scratch. Incredible work dude
Thanks man!! I really appreciate that!!!
Being a diehard Halo fan, this series has made me so happy.
Whenever I look at my framed copy of those blueprints, I am just blown away at how you brought that launcher into the real world.
This guy is awesome, I can’t wait to see his next invention, I am amazed at what he can build
We gotta come to Ohio again soon!!
2nd
who cares tho ikr

Now we just need EXPLOSIVE rockets...THAT would be awesome (if it can be done without legal issues)! Great video, as always man!
Talk to the guys at Ordinance Lab.
Some of the Estes model rocket engines have an ejection burst tip that is meant to separate the model rocket's cone top from the body in order to deploy a parachute or other gimmick. If the motors he's using had a variant with the ejection tip, those could be used to create a simulated explosion with confetti, or rigged to detonate something actually explosive, such as a small firework in the head.

They are gonna need many licenses
Fill the rocket with Tannerite
@@Jarandjar you can avoid licences if they use Tannerite which is completly legal for everyone
I literally said wow! out load when you guys started shooting the rockets! So much improvement from the last time, these look like legit anti tank weapons without the boom
Hey! So exciting to see more of your epic work! I am sorry that I had to stop supporting you on Patreon for a while... hopefully I can start supporting you again soon!
No worries! Hope you enjoy this video!
I love how oversized the launcher looks, then chief picks it up and it’s just the right size.
Realistic size man.
This is so cool! The slow-mo is obviously spectacular, but I really like how certain clips feel super cinematic, and frame-able (like 4:54)
I like how their prop armor and rocket launcher both look better than the props they used in the TV show.
Hey they didn't spontaneously disassemble, they were airbrush munitions that have a minor timing issue, but tested aerodynamically promising

Awesome work! Can't believe I'm just seeing this, we got irl spankr irl dmr irl shotgun irl magnum irl ma5 and irl warthog at this point the military should start contracting halo fans lmao
7:42 i noticed that as the fins deploy outwards they are changing the moment of inertia and killing the spin
Wow. Look at those animations!
I think you should mount an Infrared Guidance system on that Rocket to made like an Missile
I believe it is important to get the rocket up to a stable velocity as soon as possible, which is why military rocket launchers often have an initial booster before a sustainer motor.
Now you just need to put a warhead on the rockets, but that would probably be illegal in some way or another
There are so many amazing creations on youtube...
but this may be the best!
Amazing work
Your work is INCREDIBLE Jairus! Thanks for the opportunity to fire that off! Can't wait for more crazy stuff in the future!
Wow, it looks like you guys had so much fun 😊
This could honestly with some work be a viable system for an anti tank rocket system. For real. Make some removable pods like the game and bam. It's ready for the field.
I was curious when the next video was coming out!!! Thanks for another great one!

around 4:00 it starts lookin like chief in basic training getting shown how to use the launcher by the crazy weapons tech.
Next he’s gonna hit us with “so, I just build a functional gravity hammer”
DID HE SAY OHIO THIS MAN IS BRINGING MORE CHAOS TO OHIO I'm done💀
Still love nerding out over this.
Thank you for taking us along this is some really awesomeness
Oh my goodness,just....Wow!
Awesome video per usual man!! Two of my favorite creators collaborating is epic!! Can’t wait to shoot again! -Doug
Rocket go wheeeeeeee!
This should be #1 trending
So awesome! Definitely need to see a collab with Ordnance Lab and get some payloads on these!
True and the if it works well enough sell it to the us army
And Wild Arms Research and Development. They made the Fliegerfaust replica, which uses rockets with no fins but angled nozzles for spin stabilization.
Now if only we can get this in a halo movie
Kind of sounds like the Halo 4 Rocket Launcher
saw the video a couple days ago. you done well.
That BP would look awesome printed and put up on a wall
I think a discarding sabot would help your rockets fly straight out of their tubes, no rifling needed if your rocker fins are properly angled.
I really can't wait to see how you'll somehow improve on this EVEN MORE.
After a certain point you're going to start being offered government contracts lol. I personally would love to see you make a second tube so it can actually be reloaded!
This guy is definitely on ATFs watch list

Now you just have to show this baby to the Army and us halo fans can complete the mission
What an amazing collaboration, this is a seriously amazing project you've made and he hope it goes as viral as it deserves. Keep it up
From nobody to a halo gunner,I'm pround to say I'm proud of you
Wonderful video man! So close to 500k, let's do it folks!
Watch this guy create a whole halo ring next.
All you need next is to pack the rockets with timed fireworks to add that last bit of awesome
How did I only just now get notified of this?
This is such a cool project
I wonder if it needs more time to hit flying speed, maybe a longer barrel?
Super awesome video and collaboration, thanks for sharing.
This was amazing to watch! Not even a big halo fan and I was just losing my mind.
You should think about cleaning up with ordinance lab. They've already done one collaboration with another 3D printed rocket.
Your rockets are no longer straight when they exist the tube because they are not fast enough for inertia and the effects of the fins to stabilize them. Try using G74 or G80 rocket motors from Aerotech / Enerjet. Also make your 'forward fins' smaller, just enough to hold the rocket body at the center of the tube.
Awww, why didn’t you make the rocket carrying case look like the SPNKr ammo case?
"*sniff* its enough to make a grown man cry" -Sarge
Lol
A true RUclipsrs thanks is them Plugging your Murch after receiving it HAHA
I loved both videos this one and theirs, keep up the wonderful work
This is so cool! Looked like a ton of fun!
You should see if you can get a hold of the slow mo guys. They have a insane slow mo camera and I’m sure they would love your rocket launcher
This video needs 100,000 views so good
Gotta make a spartan Lazer next.
Need a collab with the slowmoguys
Dude… perfect!

I’m grinning so hard right now!!!
Should try (if rockets that big are available) to make full caliber rockets, with some extending fins
You NEED to colab with the world's tallest spartan and have him next to the launcher
very cool. what ppe have you been using to test it?
helmet, nomex hood, leather gloves, leather jacket, and science.
Thanks youtube for not showing this on my feed :). This should have more views.
you should take a look at HEATFS shells that tanks use I think they use rigid fins to help keep the shell stable
That's such a awesome Anti-tank rocket 😲
Now put a war head into the payload 😏
I’d like to see what you can develop out of of those little spinning rockets(hornets?) it looks like they just need reinforcement
Wow. This video really made me want to be a RUclipsr lol. What a life you guys have. Experiences I can only dream of. Good luck, man. Keep the vids coming.
I live right next to Columbia war machines property. He’s got some super cool toys. Wish Idve seen you around town!

Here’s our sponsor raid shado.. *skip* *skip* *skip* *skip*
So now you need to look into the rockets themselves
Definitely not the first time mach diamonds have been recorded on hobby rocket motors in slow motion.

"Hey kid, wanna make some REALLY COOL shit?"
Now we're talking.
Letting other people hold your baby must have had your heart racing and hands shaking!
You're having an issue with drag from the rear fins. The front of the rocket is encountering less resistance once it leaves the barrel.
