I read about the navy using railguns in one of the popular science mags about a year or so ago. And when they were researched in the 60's (thank you terran grunt, that's much more accurate than black and white photos...) the military did start researching them for use as weapons, even made a couple of (AA sized) guns that could shoot shells at 9000 or 6000 feet per second or something like that, I can't remember if they were AA guns or artillery.

No, a small of plastique (spelling?) would suffice.

I am very interested in the aspects of plasma and magnetic accelerating weapons.
I don't know if any of you remember my plasma write up.

Plastique? Any plastic explosive? Please be more specific. My favorite explosive, octanitrocubane, comes in crystalline form and is even more stable than C4.

Magnetic accelerating weapons... Lemme see, a man-portable Gauss rifle would need the following technologies if it were to be as practical as standard chemical propellant guns:

-huge power supply
-very efficient cooling system
-miraculous anti-recoil device
-at least 2 meters in length

None of these are possible today, aside from the last one.

i personaly dont think that a hand heald Gauss rifle first of too heavy for any soldier to carry second too expensive do you have any idea how much one of these would cost

aded to the facts Terran Grunt gave it is as likely to happen as a telleporter from Star Trek

very cool but very unlikely

Sorry, can't think of the name right off the top of my head.

You could make it almost sniper rifle like.
Instead of having rifling in the barrel, you could use pulses of energy around the barrel (use energy to cause pulses in a magnetic cylindes or coils around the barrel) to cause the projectile to rotate (thus, no need for rifling which causes friction and heat).

You could make the barrel and action into an "anti recoil" device. Just have both draw backward into the gun when fired (like that of a tank).

They power supply, that is an issue yet to be sorted out.

Cooling system.... can't use air, maybe liquid nitrogen, or something that will cool the internals to near absolute zero when fired.... I don't know....

Those are just theoretical, of course...

Some children at school I had never seen before. Apparently the fact that I was older than them and talked was funny.

If bullets were propelled by nitro-glicerin it would explode/go off if you even shook the gun.

Nitro would be a no no (too unstable, as you just mentioned)

The first form of Smokeless gunpowder used gellatinized nitrocellulose (in the 1880s, and was first used by the french army, it then later spread to other european armies). Later Nobel invented a better smokeless powder which came to be called cordite. Another was ballistite.

Ballistite is a double-base powder used as a rocket propellant. It is composed of two explosive substances, nitrocellulose and nitroglycerin, blended together with diphenylamine, which acts as a stabilizer. It burns with a considerable amount of flash and smoke, and generates a great volume of gas. Ballistite burns progressively, but at a rate dependent upon the composition and physical characteristics of the powder grain, the temperature of the powder grain before ignition, and the pressure during reaction. It is produced in various shapes to fit the rocket motor housing.

Basically, solid propellant charges, such as Ballistite, may be grouped under one of two types- restricted-burning and unrestricted burning.

A restricted-burning charge has some of its exposed surfaces covered with an inhibitor to control burning. By this procedure, burning can be restricted to take place only on the desired surface or surfaces. Controlling the burning area in this manner lengthens burning duration and determines the combustion chamber pressure for a given charge. A burning cigarette is a good example of restricted-burning, if you consider the paper-covered portion as representing the inhibited area.

Unrestricted-burning charges are permitted to burn on all surfaces simultaneously. Relatively speaking, the unrestricted type of grain delivers a large amount of thrust for a short period of time, and the restricted type of grain yields a smaller amount of thrust for a longer period of time.



Cordite N is used in aircraqft gun ammunition (any of you seen a GAU-8??- it's the one in the a-10, they Rock!)! Cordites three main ingredients are Nitroguanidine, Nitrocellulose, and NITROGLYCERIN. Cordite N is very cool burning, with little smoke and no flash, and has no flash, and has a higher velocity or burning rate than Ballistite.

So YES you can use nitroglycerin in gun ammo (and it would be stable)


As for Railguns, they would be useful as larger installments such as AA guns, Artillery, or Cannons. However, because of power requirements, and components that are bulky do not make it a weapon to be carried by hand.

For Plasma weapons, you run into almost the same problem with the railgun, as well asit would be extremely short ranged- plasma is basically superheated gas. To make it an effective weapon: 1) you need to find some element (preferably a heavier one) that can be superheated without too much difficulty, and then be able to make it retain that heat for a useful period of time, 2) You then need to be able to accelerate it to an effective speed so you can hit something other than buildings, and 3) you need to find a way to keep it together, or loosely together when it leaves the weapon, otherwise it'll expand and dissipate, very, very quickly (probably end up damaging the weapon instead).

As for particle weapons, we could make them, but their size would be Huge, with no way to aim it, or direct the "Beam"-as in accelerators tend to be miles long. So it won't be for a good while before we can bring the size down to Military usefulness type levels.

bah

To make a railgun, all you need is a huge power supply, and superconducting coils. Superconducting coils won't overheat with use. Recoil isn't a problem at all if you fit it onto a tank, and handheld versions wouldn't need the velocity required to cause massive recoil.

Yes, but then there would be no reason to use them over standard slugthrowers. Also, they do generate a lot of heat. The longest range Gauss gun I know of that someone built at home shot 285m and it heated so badly that it could only fire four times in a minute.
