I Built a Supersonic NERF Blaster

[@MikeShake]

Edit: In pt.2 I'll obviously measure the speed of the supersonic shots to verify it's actually supersonic. Also I’m gonna get better darts (half length) and try a few interesting projectiles. Also I’m currently trying to organize something here in the US for part 2 so there’ll probably be another video in between, but I think it'll be worth it. Edit 2: shout out to Joerg (slingshot channel) and IDAT who made similar projects way back, I wasn't aware of them but they're great. Check them out too! Got injured in an accident?

There's a few things going on here that the lower pressure solved for you. First, the darts will explode and get shredded at higher pressures because they're smaller than the diameter of the barrel. When the valve dumps, that sudden blast of air pressure forces the foam to expand outward and squeeze to the inner diameter of the barrel, creating an air-tight seal. This is known as Obturation. If your pressure rises too high too fast, the projectile will expand too much and seal too tightly against the barrel, and that will shred it from the pressure differences, acceleration forces, and friction. This also causes the head to fly off, and the dart to leave in more than one piece, since the foam section is smashed against the walls of the barrel while the smaller dart head is free to separate. The lower pressures are more gentle, allowing the dart to fully obturate the barrel immediately and accelerate more uniformly, staying together and leaving the barrel in one piece with all of the pressure remaining behind it the whole length of travel for maximum efficiency. Second, the hissing sound you hear at higher pressures is called Valve Lock. This happens a lot when trying to tune Large-Bore hunting PCP airguns. Whether because the projectile is being shredded or leaving the barrel before pressure can equalize, the pressure in the barrel drops too fast, and the valve can't close until you reset the system. Or put your hand over the muzzle, probably. Rapid-dump valves like this need forward pressure from the barrel to help close the valve again against the static pressure in the bottle, and this usually happens before the projectile even leaves the barrel. The lower firing pressure means that the valve can equalize more quickly and close properly, conserving air and dumping its energy more efficiently. It's this efficiency that got you the greater velocities.

[@MikeShake]

Very interesting, thanks!

[@proteusmaximo8659]

I feel like I'm on Physics lession...

[@BartJBols]

@@lisaridener7514 High pressure increase squishes the dart, making it get stuck in the barrel and rip apart. The valve also isnt made for this application so going from very high (firing) to very low (projectile leaves barrel) pressure makes the valve get stuck halfway. (hissing noise) Therefore lowering the pressure a bit stops the dart from getting squished and thus leaves in one piece, and stops the valve from getting stuck. Both help the projectile get more performance for less pressure.

[@WarlordEnthusiast]

@@MikeShake So based off what @SnowblindOtter said, you can pump the pressure back up to 600 PSI but you need the projectile to fit snuggly inside the barrel and to calibrate the barrel length to the PSI your using. If your going to do 3d printed projectiles, I'd recommend a Teflon seal around the projectile, Teflon tape would work for this, just create a groove around the projectile and wrap tape inside this groove, when air pressure increases behind the projectile, the Teflon will expand and create a very strong seal. What I used to do with potato cannons was a 3d printed wad that had a set of rubber O rings around it, the wad pushed the projectile (A potato) and almost doubled the FPS I was getting. If you want to truly push this creation to its limit, look up discarding sabots. They've been 3d printed before and used in HHO guns, the velocity you could achieve with those could actually be lethal with this gun. I'll see if I can find it but I remember seeing equations on an airgun forum specifically for figuring out what barrel length is required.

when you 3d print your own custom darts, tracer darts would look so interesting when shot at night. You could make a tracer dart by puting a small led and a very small button cell inside/at the back of the 3d printed dart. Also you could try printing the darts with glow in the dark filament and charging them with a black light before loading them in.

[@MikeShake]

[@SatoruGojo574]

Hi mike

[@johnalbrecht7868]

​​@@MikeShake You can actually get some "real" tracer foam darts from a company called worker. They're a shorter length, but that might actually help them go faster. There's also a company that makes a tracer faux suppressor type thing, depending on the OD of your barrel might mount on the end with no modification. It's called the T238, and also imparts spin on the darts to help stabilize them. Obviously not meant for these velocities though so might not be useful at all.

Great job! In fact you should increase the power of the spring that yanks open the valve. Yours seems a bit weak. I used rubber bands of course, and lots of them. The faster you open the valve, the harder the shot.

[@MikeShake]

Joerg! So sorry I didn’t mention you in the video. I later on added you in the pinned comment when somebody mentioned your arrow launcher. It was insane! Do you think even if I’m using a QEV valve, the fast activation of the ball valve would have that much of an impact on the overall speed?

[@Slingshotchannel]

@@MikeShake The problem with QEV valves is that the max pressure is fairly low and the throughput is limited. My experience is that the highest power can be achieved by using super high pressure - I go up to about 300 bar - and then yank open a ball valve as fast as possible, You need to reduce the friction in the barrel so the dart stays intact. Maybe it would make sense to put some oil or grease on it. Also I recommend trying a sabot, maybe some soft tissue, behind the dart so the air hit is cushioned a bit.

[@Hellhorde.]

​@@SlingshotchannelDon't forget though adding a bit of oil to an airgun may not bode well using foam darts if diesling occurs. Sounds fun when it happens with air rifles but in this configuration it may cause unwanted results.

[@m0-m0597]

It's the JOERG

[@boneiy]

@@Slingshotchannel do you perceive any additional benefit to perhaps using a Rupture disc as the valve? It's already a muzzle-loading device, so replacing one each shot wouldn't meaningfully interrupt the loading->firing process. I feel like it could help with trying to push velocities as high as possible, as well as changing the gas.

As someone who has some 'Nerf for adult" blasters. Dart Zone and Worker half length darts are considered to be one of the best in the scene right now. Some of the high end blasters (Dart Zone Pro line, Gameface Trion and Worker blasters) are doing 200-300 FPS out of the box so those darts are made with these numbers in mind, where Nerf Elite darts are designed for 70-80 FPS. The community would be more than welcome to help you out!

[@nonasuomi282]

I also wondered abut the darts- looked like the first ones he was using may have actually been new old stock streamline darts, which would certainly explain why they were failing. Not only were those designed with about half the pressure/velocity in mind as Elite darts, but they were probably significantly older as well, allowing more time for the material to begin to break down. But yeah, going with Workers or something else more suited to hobbyist grade blasters would probably give even better results.

[@CygnusRising]

It was funny watching this and going, "Yep, Spectre figured a lot of this out years ago..." although his goal was never supersonic and instead wanted repeatability and had a formfactor he was trying to fit, so the design parameters are a lot different. When going for supersonic, you definitely should go 'old school' with solid-core front-weighted 'Stefans', traditionally made out of foam backer rod.

I've always wondered about trying to build a Nerf biathlon rifle, this is probably the closest anyone has ever got to it! Try using half-length darts next (ideally from Dartzone), they are faster and more accurate. You should definitely test long range accuracy with different ammo. Also Dartzone darts have better glue than original Nerf darts and use thicker foam, so they are far more durable. Of course they have never been tested at supersonic speed, so I'm not sure how they'll behave, but I'm pretty certain that they'll be much better than the standard-length darts you used.

[@michaellee4276]

You also get better results when the rubber head has a much smaller diameter than the foam body (like those half-lengths from Dart Zone or Worker). The flexible foam body expands under pressure to provide an air seal so you don't leak pressure, but also causes drag (not as much as rubber). Bamboo style darts keep the seal, but reduce barrel drag. Those hard plastic darts may have trouble sealing the air behind the dart, and/or cause too much barrel drag.

To add another option. Worker half darts have even better glue than Dartzone, and are easier to get in countries outside the USA. The 1.2g versions would probably work well here.

yeah but then the reason you'd never lose a nerf war would be because everyone else is either in a hospital or 5 feet under 😕

Mike slowly becoming like a science channel, epic

[@wilmofosho]

The breakdown of the valve system was really cool and well done. Showing how the air moves and how the system can be reused in the digital version really helps to understand how the whole thing works. I would guess the wispy noise it was making was bc the system was overcharged and the extra pressure that is in the system after ripping the dart apart is slowly leaking from the second tank from the trigger system not being reset instantly. When the everything is lined up right all the pressure is pushing the dart the whole way and there is no extra to leak

[@briankronberg]

The noise you hear afterwards is what you explained in the valve explanation. It is the 400 psi being refilled in the second tank after your shot. Next, try 3d printing a Nerf dart and using a solid design dart. It will be heavier forcing a higher PSI to get the same speed, but the damage will be WAY higher, so be careful.

[@AgedFactual]

Sound is temperature change. The barrel is cooling down or heating up, thus creating noise as air leaves the barrel. When you shot in the field, the barrel is warmer. Larger diameter, less room to tear apart the nerf dart from over pressurization. Edit: the barrel needs rifling, and you have to take temperate into calculating.

[@TiffanyBell-fq1xo]

bro how fast the nerf bullet went at 8:27 no even the flash could dodge it that's wild any ways love this guy hope he keeps up the good work

[@yurichtjuatjawidjaja4133]

Probably 18:27 buddy

[@pyro5847]

I've noticed that the darts didn't tear when you used the container with the hose. The hose creates resistance and prevents a sudden pressure spike that would destroy the darts. You could vary the hose's diameter and length to achieve optimal pressure in the barrel during the shot, ideally maintaining a pressure close to critical throughout the entire barrel length. As for the projectiles you want to print, it's best to make them aerodynamically stable. Otherwise, you'll need a rifled barrel where the twist rate matters, or the projectiles will spin in the air, reducing accuracy.

[@3amdion860]

Everyone give Mike a like. Doesnt cost anything. Yet he spent 13k euros for a video. A like is the least we could do...

[@K_Obradinn]

That low vibration when you fired the cannon is just so frickin COOL, god that is epic

[@perfectparadox7389]

Just to be safe, make the trigger and tip of the barrel very clearly orange!! That makes it less scary for other people (and the cops) because now it looks very much like a real firearm. But amazing work as always!!

[@MikeShake]

Good idea, I’ll 3D print an orange tip. Thanks!

[@tomclanys]

Because it most probably counts as a real firearm and is illegal. Idk about Italy, but in Poland it's a limit of 17 joules in an airgun. Anything above that needs to be registered. At the speed of sound with a 1g dart he gets around 58J, so in a LOT of places that's already a weapon that needs a license.

[@bolasquirrel5631]

This is closer to a real gun than a toy now anyways

[@theprogrammer1]

Just the tip!

[@PatGilliland]

@@tomclanys In Canada, over 900 fps, it's a firearm.

[@Gunbudder]

you can modify an electronic irrigation valve (a solenoid water valve) to work manually without a battery and with air. there are a bunch of guides online, but essentially you drill a hole in the top of the valve where the bar travels into when the solenoid is energized normally, and you install an air fitting. then you simply attach an air filter cleaner with some air hose to that fitting. then you put air pressure on the input side of the value (where water normally goes in) and your output air on the output side of the valve. when you press the trigger on the air filter cleaner gun (which in normal use would start shooting out air) it will allow air to flow through teh valve instantly. or nearly instantly. this is because of how the diaphragm inside of the solenoid valve works. alternatively, you could just use a 9 volt battery to trigger the valve and not modify the valve at all. either way, solenoid valves for garden irrigation tend to open WAY faster than most other valves you will find. its like a resettable burst disc in a way

[@rehanb637]

Personally I’d go with proper pneumatic solenoids over irrigation solenoids. They aren’t that expensive of aliexpress and are designed to handle high air pressures

[@thundercrowz]

You should definitely try dart zone bamboo darts and half darts they use a much stronger glue.

[@aster-x1876]

Bravo, superb creation. I think that if the barrel was rifled the projectile would go even faster and the aim would be more precise.

Awesome video dude. Love the "I'm just gonna figure this out as I go" mentality of tackling projects. I think you learn much more that way, rather than doing all of the research beforehand and just building and pretending to be an expert on a thing. It's much more human. Keep up the awesome builds brother. Also, love the weathering job you did on this!
