More Powerful Bullet

I was thinking that the area where the bullet is pushed onto the casing
could be made air-tight, and the percentage of oxygen in that area
increased. This would cause a higher percentage of oxygen to be inside of
the closed bullet. This should make the bullet more powerful with the same
amount of powder. For pistols it could guarantee that all of the powder is
burned before the bullet left the barrel, increasing the power of the
bullet.
The percentage of oxygen in that area could be increased in increments and
the bullets tested to see if they are stable and would not go off when you
don't want them to. The temperature at which they would go off could be
tested also. Also the muzzle velocity of the bullet and its power would be
tested. These tests would be done at each stage of increase in the
percentage of oxygen that is used when the bullet is pushed onto the casing.
It seems to me that if pure oxygen is in the bullet, something like card
board ( and many other things) would burn fast like gun powder and would be
suitable to propel the bullet.

Some of that is good thinking. It may do something for the propulsion, but
two things are being overlooked:

1. Your powder does not depend on the oxygen inside the case for it's
"combustion".
2. If we already are limited by the pressure our gear will handle, and have
to keep powder charges limited, how will we be able to use this theoretical
gain in pressure?

I think that if you left the earth, traveling to the moon, at just above the
speed of light, you could land and then watch yourself coming.

Hi Stone,

I agree that it is good thinking on your part, but I think that the
benefit would be so marginal that it wouldn't make any difference in
velocity....

The powder in a cartridge contains its own source of oxygen. In
gunpowder this function is performed by nitrate salts (saltpeter).
Modern bullets use other materials to do the same job. A well-blended
propellant will leave no unused material. For a given type of powder,
the 'power' (actually the energy available) is a direct function of the
amount of powder used.

Google "smokeless powder", "black powder", and "muzzleloading".


It is important in small arms that the pressure produced does not
exceed the ability of the weapon to withstand it. You don't want the
*gun* to blow up. For this reason high explosives that produce high
peak pressures are not satisfactory propellants.

Ideally, the pressure should build rapidly to the maximum level and
stay there while the projectile is within the muzzle. This requires a
*fast-burning* (rather than an explosive) propellant. The best
propellant will burn at a steady rate, timed such that the burning
finishes just about the time the projectile reaches the end of the
muzzle.

An explosive will peak quickly, but then the pressure will fall as the
projectile moves down the muzzle. While this is happening, the
projectile is experiencing back-pressure caused by the air building up
inside the muzzle *in front of* the moving projectile. The net result
is that for much of the trip down the muzzle the effective pressure on
the projectile produced by an explosion is actually less than the
pressure produced by a fast-burning propellant.

The kinetic energy imparted to the projectile will be the integral of
the force (pressure x are at the back of the projectile) through the
length of the muzzle.

Some improvement (within reason) can be made by extending the muzzle,
but there are limits to the gains that can be made this way, and there
are disadvantages to a long muzzle.

I imagine if one wanted to maximize power he would adjust the gradation of
the powder to maintain peak pressure all the way down the barrel. i.e a bit
of
fine fast burning powder to build pressure quickly and then a proportion of
coarser slower burning powder to maintain pressure. Experimentation with
bullet weights, powder gradation and pressure variation down the barrel
would
be needed.

None, and I mean none, appreciate tongue-in-cheek sarcasm.

So, tell me, a ray of light becomes infinite in mass when it travels at the
speed of light. Interesting. I think I'll go move the car with my laser
