Nerf Gun Shoots Super Sonic Nerf Darts – Mach 2.35

This guy made a super Nerf dart gun. He uses metal pipe as a barrel and hooks up an air tank to it.

 

In the video they show that the dart travels 80cm in 0.001 sec which comes out to 800 meters per second. Which comes out to Mach 2.35.

 

I was rather impressed with the amount of energy it has when shot at the plywood. I wonder if someone with a high speed camera could recreate this and see if the dart creates a sonic boom like those pictures we see of planes breaking the sound barrier.

    This makes me want to try making similar with a long smoothbore “barrel extension” to launch the dart, and a thick wad of course, launched by a blank. Done right it could go even quicker… of course, for maximum speed, someone will eventually have to make a Nerf light gas gun!

    That Nerf Elite Dart in the YouTube video has a mass of 1 gram
    The Muzzle Velocity was Mach 2.351 ~= 806.393 m/s ~= 2645.6463 fps
    KE = 0.5MV^2 = 0.5 x 0.001 kg x (806.393 m/s)^2
    KE = 325.1348352245 joules ~= 239.80714787309176 fpe

    So that’s about upper end .22LR muzzle energy range

    I wonder how much it would hurt if you got shot with one of those without body armor

      About like it feels when the dentist says “You might feel a pinch.”

    I want to see a 2cm slug of copper suspended in plastic propelled to lightspeed
    like the weapons used in “Hammer’s Slammers.”

    This reminds me of Mythbuster’s test with the supersonic ping pong ball.

    Neat. I’m a bit interested in light (low SD) projectiles. Yanno, the foot-poundage is usually impressive, as is short barrel performance and the terminal performance is interesting at least.
    Maybe not ethical for big game, maybe short of FBI penetration, but heck of a mess.

    Had a friend demonstrate his pneumatic cannon and he accidentally shot a wet, wadded up paper towel through the dry wall in his garage.
