Concorde Vs Bullet

OK, i think you are looking at the problem a little too simply. It is not just a relative motion issue. Air travelling towards the aircraft would not be able to enter the muzzle (as it has nowhere to go). The bullet would then travel down the muzzle at the speed of sound say (I know it has to accelerate but lets just say it travels at a constant speed) relative to the muzzle (i.e. the bullet would be travelling its velocity plus that of concorde). Upon reaching the end of the muzzle it would hit a wall of air travelling at the same speed as it so would effectively instantaneously slow down to the speed of concorde. It then could go one of 3 ways, it could bobble about in the space between the end of the muzzle and the air around (the boundary layer), fly back past the aircraft and possibly hitting the aircraft on the way past or it could go bounce back down the muzzle. Do you have any idea how much energy it would take to stop a bullet in an inch or two when the bullet is traveling 3,000+ fps? Matt |

Good question Mont. I've never read anything about MiG-15s flying in Vietnam, but I guess there may have been a few kicking around, maybe early in the war like you suggested. All the North Vietnamese aces flew MiG-17s IIRC. When you consider some of the hardware from earlier wars we had sitting around on airfields over there... Montblack |
