A few more thoughts on the Nerf Cannon.
Yes, I know if I used a longer barrel I could get higher speeds, but I did not want to deal with a 20ft long gun. I think a 6ft barrel was enough to show what a supersonic nerf dart can do.
Davekni got a pingpong ball going 2000mph which is 2930 ft/s!! (mach 2.5). His barrel was 20ft long. It can shoot through 3/4in plywood! You can see that video here- • Supersonic Ping Pong B...
I always thought the speed of sound was the limiting factor, because the flow 'chokes' at mach 1. Its a big controversy among air-gunners, and theres like a 900 post topic on it here www.gatewaytoairguns.org/GTA/.... Some guy got one going like 2100 ft/s which I thought was impossible. • 2035 fps PCP Airgun L... So it prompted me to do some research.
It turns out flow does choke at mach 1, but its only the mass flow that chokes. The gas can still expand supersonically.
Also a big thanks to Dr. Carl Knowlen from University of Washington, and u/Overunderrated, u/TheQueq, and u/InductorMan from reddit.
Here are the papers I referenced:
A COMPARISON OF DISTRIBUTED INJECTION
HYPERVELOCITY ACCELERATORS - www.researchgate.net/publicat...
Probably the most concise and easily understood!
Numerical Evaluation of a Light-Gas Gun Facility for Impact Test
www.researchgate.net/publicat...
Shows different muzzle velocities for different barrel lengths
THE THEORY OF HIGH SPEED GUNS
www.dtic.mil/dtic/tr/fulltext/...
Probably the most extensive on the subject "The reader Is assumed to be an advanced student in engineering." I hope you payed better attention in physics that I did.

  • This is my favorite video of yours yet!! Awesome design considerations and nice job on the construction. Plus the Schlieren imaging was super cool to see. I would have never expected nerf darts to survive being shot at supersonic speeds!

    • haha thanks! TBH I kinda had to cheat and reinforce the nerf darts. I just used tape and earplugs, or filled the center with polyurethane foam because I did not want to add to much weight, that would invalidate results. Im waiting patiently for your CO2 laser rifle, and flash powder pumped laser!!

  • I have done something similar using a big bore airgun and a disposable Sabot to house the nerf dart! That way you don’t have to thread the dart and the sabot will engage the rifling - it also worked best with my 1100psi output (3k PSI rated with 4.5k burst discs) HPA tank but I didn’t use Helium so maybe you got comps with that due to the pressure differential and the excitability of He. I’ve used He before in my Benjamin Bulldog (Pitbull Mod) but idk if it performs proportionately better at lower PSI’s. It didn’t work super well with my more powerful HPA tanks. Rather than 3D Print the Sabot like normal - since it’s so lightweight inside the sabot - I had some success making some large gelatin capsules into sabots but the most success using water tubing which I perforated in a few different patterns My favorite project is something you might like - bc it’s like a more dangerous version of lawn darts - but it’s essentially the same principle but using flachettes. Bonus points if you can super glue a cap from a capgun over the tip to make it pop on impact. Idk if you could do that with a nerf dart but it would be cool! It would probably destroy the dart with some fun foam expansion but you’d have to put a sort of hard plastic cylinder in between the top of the dart and the cap to activate the cap

  • Maybe his tank was larger and his barrel was longer so it was able to accelerate for longer. Perhaps this allowed him to use a lower pressure so that the force from the pressure wouldn't rip the dart apart. Instead of designing it to accelerate it by a short burst of high pressure you could design it to accelerate with a longer bust of lower pressure.

  • If there's a problem with the pressure behind it dropping, what about having multiple pipes into the barrel that direct gas forward at an angle? Seems like it would push air out of the way forward, letting the projectile move forward easier, and then when the projectile passes the input port the gas pushes the projectile. Like the shape of a long tube with very sharp V shapes that point toward the end to force more gas forward.

    • I'm pretty sure, actually, from a crystal chemistry point of view, that I know what the spark is coming from. It's from the glass. You see, it takes a lot of energy to break a bond chemically, same as anything else. Glass is a crystalline silicon lattice, so it tends to have very tough bonds that are a mix between chemical bonds, and ionic ones. I think the sparks are coming from the nerf dart going SO FAST when it hits that the glass is broken harshly enough to make the ionic bonds separate and *emit light* as a result. It's not a spark, it's a photon. That's why you can't light the lighter on fire with it - it's not heat energy. Just my theory though.
