Firearms In Space - General

[QUOTE=Run&Gun12;27262364]Didn't the astronauts of the Apollo missions carry a Colt .45 pistol, in the event that if they had no way to propel their spacecraft, they'd use the recoil from the gun to push it forward?[/QUOTE] And they'd just stand outside the spacecraft shooting into space with a gun would they?

One step closer to Shattered Horizon.

When I was younger I though firearms wouldn't work in space because there's no gravity.

[QUOTE=Killerelf12;27244193]What happens if you happen to be in an area of space where all the gravitational forces on you cancel one another out? There'd be no net gravitational force then. What would that even be like?....[/QUOTE] From your perspective, there would be no unbalanced forces acting on you, therefore you wouldn't be pulled or pushed in any direction. In effect, it'd be the same as no other objects being around you at all. So yeah, that'd be pretty boring.

[QUOTE=Tacosheller;27242328]Just use crossbows Little to no recoil[/QUOTE] wait, I was wrong, it would do the same thing.

[QUOTE=mugofdoom;27254759]The thought of Soviet Cosmonauts in space with 23mm antiaircraft guns just game the biggest fucking boner ever. [editline]7th January 2011[/editline] No, none use air pressure for any reason. Except maybe those old air guns the French (correct me if I'm wrong) used in the 1700s.[/QUOTE] Even if it was an air gun, i'm sure you could fire it in space. In fact probably more effectively than on earth, as there'd be more of a pressure difference between the vacuum outside and the pressure of the gas behind the projectile being fired.

You wouldn't need to have adjustable sights and scopes or anything that would be cool.

cbf to read entire thread but easy solution: have large earth air mixture (70% nitrogen etc or whatever) tank compressed on back have computerized system of tubes n shit set up that it blasts just enough air into the barrel for the powder to fully burn before trigger is pulled have secondary system set up to blast your air mixture over parts subject to heating up such as barrel, gas tube thus absorbing the heat and flying off into space have tertiary system for spraying a jet of air backwards that is precisely the calculated recoil to effectively cancel out gun recoil problem, science? [editline]7th January 2011[/editline] also you would have to make sure you have an extremely tight sealing cartridge in the bore or possibly a sealed receiver to ensure pumped into barrel pre-firing doesn't leak out

The main problem is lubrication for the parts; it tends to boil off in an airless environment, though there are special lubrications and materials that can counteract that. Heat isn't that much of a problem, either; one of the main ways a gun cools down is ejecting the hot, spent casing. There's also radiating out that heat, as opposed to conduction and convection.

Really what's the point of using moving parts in space when bullets can just have electronic ignition?

[QUOTE=Mr.Dounut;27273813]do you have downs[/QUOTE] Do you?

[QUOTE=POLOPOZOZO;27267817]Really what's the point of using moving parts in space when bullets can just have electronic ignition?[/QUOTE]The loading of a new round and the ejection of the spent one, for example.

Wait wait wait what's this about metal in space instantly fusing together when put together? Why are we not exploiting this somehow? We could be sending up bunches of metal with random launches and fusing it together... or something. I don't know.

What would be the use of fusing together metal? There's absolutely no point in doing it.
