Without the irritant I think it will only be effective at creating a barrier while it’s burning, the sparks from a fountain isn’t a reliable fight stopper..
Look at this fountain that’s ignited at 0:26
It has a big flame that reaches 4-5 meters, burn 16 seconds, and the unit is smaller than...
The pyrotechnic flame will be similar to that of a firework fountain, so it will have a very low chance of putting things on fire. It would require something highly flammable in order to ignite it.
Wouldn't it be more efficient to pyrotechnically expel the content of a can of pepper spray? I don’t mean like a tear gas/smoke bomb that contaminate the air everywhere around it. But like a fountain that you point towards a specific direction, like a spray can, that reaches several meters. In...
Look at this picture of two superposed loads:
Imagine that each bullet weight 150 grains and each gunpowder charge 50 grains.
If the rear load were to be fired first, it would be equal to firing two bullets +the weight of the front gunpowder charge. So a 350 grains bullet with a 50 grains...
Why would the recoil break my wrist if the arrow is of the same weight as a bullet that don’t break my wrist? If the weight of each projectile and gunpowder charge are equal, the recoil should be equal too?
I think blow back from the propellant charge might be the biggest issue with this...
I get that a solid cylinder will hold together each chamber, but not why such a cylinder would be better at retaining the pressure inside the chamber at its weakest spot.
Look at this cylinder for example:
If you put one round inside this cylinder and fired it, why would that be different to...
Does the honeycomb configuration of a solid revolver cylinder increase its strength? I imagine that it will rupture at its weakest spot anyway, which is the locking slot? I also wounder how much a thin brass cartridge would really add to its strength?
I don’t think this concept will work for rifles, it’s for handguns. I’ve seen revolver cylinders having less than .004 inch wall thickness between chambers. I’ve thought about blowback, this might be a big issue. But won’t the force of the propellant charge be directed more towards the front...
1, not necessary, it depends on the material it’s made of. Short crossbow bolts are about the same weight as a 9mm bullet, and those bolts are over 4 inch long, the projectile in my design is only 2 inch. However since it will contain pressure, does it have to be as strong as the barrel? Or will...
Why is that? Look at this picture:
The same gunpowder charge is used. Then look at this picture when it’s fired:
There’s not much difference in term of barrel volume between the normal gun barrel and the short (half the length) gun barrel + hollow arrow. If the arrow and the bullet have the...
I saw an airgun that shot arrows. The arrows was placed over the barrel instead of inside it. I realized that this will make the effective length of the barrel increase, without increasing the length of the actual barrel.
I made a picture to explain what I mean:
I hope you get my explanation...
