Hi people, anyone of you here is very good with impact mechanics experiments using the ballistic gas gun?
I am doing this project for a few months already but still can't get the experimental set-up correct... hopefully someone here has done it before and can help me with it...
I am supposed to fire a small cylindrical shaped projectile through the barrel. However the diameter of the projectile is smaller than the barrel's inner diameter, so I have to make use of something called a sabot... the sabot has the same diameter as the barrel's inner diameter and it has a small hole in the middle for my projectile to sit in... Normally that solves the problem, but for my experiment, I have to strip the sabot off the projectile after it leaves the muzzle... I tried many ways of doing it but most of the time, the projectile path gets affected after the sabot has been stripped off, ie. the projectile either deflects or tilts..
Anyone knows of a way of stripping the sabot such that it will not affect the flight path of the projectile? I need to achieve a perfect head-on collision.. Your help will be greatly appreciated...
Thanks a lot!
Look at how a tank fires off it's main round; pretty similiar;
this might help:
