In Response To: point of diminishing returns (TheRoost) : for every mass unit of gas that exits out the back of the weapon at a given
Actually, having more gas exit the back is *better* for efficiency. A larger mass has less kinetic energy, at a given momentum, than a smaller one (because kinetic energy is proportional to momentum squared, divided by mass). So a larger amount of recoil gas will carry less kinetic energy, leaving more for the bullet, which means a higher muzzle velocity. Of course, you'd have an even higher efficiency if you *didn't* have gas vents, because then the whole gun (and the person shooting it) make up the recoil mass. But it's entirely possible to raise the efficiency of a recoilless weapon as close to 100% as you want by adding more and more recoil mass. --SiliconDream |
