Modern powders have their own oxidizers in them. A gun would fire in space, but there'd be heating issues due to lack of convection cooling. It would cool only by radiation, which is much slower

Firing a gunpowder weapon in space is possible, as >>35027589 said the lack of oxygen does not prevent powder from exploding.
Bullets would even go way faster because of the lack of friction.
The problem is that they may never stop, and this is the reason I think we may never see kinectic weapons in space. When you fire a weapon you want something you can somewhat control, and missing your target in space means that the bullet ends up god knows where.

They'll work, the propellent and primary you use might have to be changed. Going back to many (many) years of old chem labs, smokeless powder is inert at around -70 to -80C (can't remember exactly) and it does get very tricky at the higher temperatures. Not so much that it won't explode at a high temp, but it will be more vigorous enough to the point that the powder develops more power. So at around 60C you're getting about 10-15% more power, which is not good for Mr Gun and it gets really outrageous at around the 240C mark to the point you might want to get someone you don't like pulling the trigger.

Primary explosives are a bit more tricky, mercury fulminate we use in primers will work down to about -90C before it shits the bed and doesn't want to play any more, once you get over about +100C the fulminate does tend to begin degrading badly to the point it might or might not work, or at around 150-180C it might just do its own shit and blow up because fuck you and all you hold dear.

Space can get very hot and very cold, so this is an issue for our space guns. We will need better chemical and primary explosives, which we can do. If there's anything we do well its killing cunts betterer than anything else on this pussy, gay arse planet and god willing we will murder anything in space as well

>>35029105
The main problem as I see it is that without air flow the guns will overheat very quickly with no means of cooling down. Any weapon with a burning propellant will need some hefty cooling device.
And then there's the whole recoil sucks in space thing

>>35029131
Guns at the moment in our current use don't really have to develop much further to be effective in just about any environment you can imagine. Except underwater, but that's different
Space M2 of the future might just need to have something like a high temperature ceramic barrel with a tungsten liner that can cope with anything short of 3900C and not turn into a floppy donkey cock, teflon coated surfaces can deal with most stuff if you want to deal with in terms of lube, at least for short term use. Course if you walk into anywhere and ask for something like that, they'll probably just think about it and ask how big your budget is before throwing your arse onto the street.

Actual recoil we could use to our advantage, in some ways the recoil operated guns we have now are an easymode way of getting bullet into chamber. Space M2 might just go, you know fuck it, we've got high density batteries and motors, just stick the bullets into the barrel with it that way, the rounds themselves could go into a recoiless rifle style case format and a bit of extra gas-tube jiggery on the muzzle might let you compensate a little more.

We can do lots of things, we don't bother though because its mostly unnecessary and fiendishly expensive at this point

>>35029131
Space is too fucking cold, the problem won't be overheating but rapid changes of heat and cold causing massive strain on anything. If you're in literally-fucking-zero-kelvins space and you blast a propellant it takes some MASSIVE metal treatments to not straight up shatter. Current gun metal treatment does not apply outside of earth temperatures and even some of the artic tier temperatures will cause serious problems.

>>35029011
Probably not, grease is very "slow" and most autoloading weapons require fast action.

Maybe a dry lube like graphite will work. Or maybe the only guns that will work in space are bolt actions slathered in cosmoline. Buy milsurp for the upcoming space war.

So shooting guns in space might be a no go, but what about using firearms on Mars? Would cooling off still be a problem??

>>35028100

Sound can travel through more than oxygen..........................................jarhead?

>>35027550
This is true. Without air to conduct heat from the barrel, it would take much longer to cool down since it would only loose heat through radiation. Other constants are thermo-linear expansion of the interacting pieces, parts might not interact with one another properly at crazy low or high ambient temp (depending on if its in the shade). Practically shooting with small arms would also be difficult because of recoil without a very heavy mass to support the shooter, otherwise he would end up spinning in circles and flying backward after a few rounds. the Gyrojet guns took care of all of these, but have obvious shortcomings

>>35027522
Without oxygen to form a thin film of oxidized metal, metal parts fuse together on contact.

It's actually a huge problem in space.

>>35028349
only acceptable for aircraft mounting because the rate of fire overheats it too much (1300 rpm vs around 600 for M2) unless a slipstream of airflow is running over the barrel. It could be used in short bursts on ground but wouldn't be capable of sustained fire

>>35029500
Cooling on Mars would be slower due to the thinner atmosphere but nowhere near as bad as in space. If we just added more and better heatsinks and stuff it should be fine.

>>35027686

Space is actually a few degrees above absolute zero, at around 2.7K. But as others have mentioned, lack of convection cooling in vacuum means huge issues with cooling.

Solar atmospheric erosion is a process that takes millions of years. With factories freeing gasses from the rocks into the air constantly we could have a Mars with a thick enough atmosphere until the sun burns out.

Too late on the prediction, Nostradamus.

https://en.wikipedia.org/wiki/Salyut_3#On-board_gun
The Salyut 3, although called a "civilian" station, was equipped with a "self-defence" gun which had been designed for use aboard the station, and whose design is attributed to Nudelman.[1] Some accounts claim the station was equipped with a Nudelman-Rikhter "Vulkan" gun, which was a variant of the 23 mm Nudelman aircraft cannon, or possibly a Nudelman NR-30 30 mm gun.[12] Later Russian sources indicate that the gun was the virtually unknown (in the West) Rikhter R-23.[13] These claims have reportedly been verified by Pavel Popovich, who had visited the station in orbit, as commander of Soyuz 14.[12] Due to potential shaking of the station, in-orbit tests of the weapon with cosmonauts in the station were ruled out.[1] The gun was fixed to the station in such a way that the only way to aim would have been to change the orientation of the entire station.[1][12] Following the last manned mission to the station, the gun was commanded by the ground to be fired; some sources say it was fired to depletion,[12] while other sources say three test firings took place during the Salyut 3 mission.[1]

Prolly not until the .50 BMG outlives its usefulness much like the 5.56 with the M4. It's just too good at what it does to really be irrelevant.

The only gripes I ever had with the M2 were having to check the headspace and timing every time, the weight, and the reliability. All of these things can be improved upon and they've already eliminated the need for headspace and timing checks at the operator level with the M2A1, and they added a decent flash suppressor on it to boot.

I could see improvements in technology and manufacturing processes resulting in lighter components to shed a few pounds but it will always still be a heavy bitch, but hopefully they can do something to improve reliability on these beasts.

The space is zero Kelvin bcause there is no matter there at all. The gun would be significantly warmer, about the ambient temperature of whatever environmenr it was in that last had an atmosphere, plus some for solar radiation heating it.

>>35036685
Nothing is zero Kelvin. Space is a 3 dimensional measurement of direction. It has no temperature because temperature is a different dimension. Temperature is a dimension measuring the average amplitude of atomic vibration. It is a massless unit designed to be consistent across all atomic configurations. Temperature does not describe heat, but it is a component of the concept of heat (heat is the energy transferred between two masses at different temperatures)
>>35036721
and there's no such thing as a perfect vacuum, even in space. The concept of "outer space" is an oversimplification at best, a fallacy at worst.

>>35036721
temperature does NOT require mass. Temperature is not an absolute measurement, it is a relative (and derivative) measurement. There is only temperature difference. Units of temperature measure position on arbitrary scales that are defined by common phenomena. Celcius is defined by the phase transfer points of liquid water at atmospheric pressure. in space, most mass will be in gas phase at ~.00000001 atm. It's temperature might be 100 K or 1000000K but either way you will only encounter .0000001g of it at a time. You will receive no appreciable heat transfer from any matter you encounter in "outer space", regardless of it's temperature. Since you will be radiating energy with no appreciable matter around you to insulate (or reflect or remit back at you), you will be cold (negative net heat transfer).

the feelings of "hot" and "cold" are measurements of heat transfer (hot = net heat transferring into your system, cold = net heat transferring out of your system). The concept of a temperature being hot or cold is an abstraction or a colloquialism, depending on how you look at it.

You don't really learn anything until you can (successfully) teach it to someone else.

Just dunk the fuckers in cosmoline. Problem solved

Since this thread was taken over by space guns, here's a question. Would gas-operated guns be a bad idea in space? Here on Earth, firing an AR non-stop will probably ruin the gas tube before anything else. In space, that heat threshold will be much lower, since cooling via radiation will take a long time. It's especially bad since the gas tube is inside the forend, so the heat would simply radiate back onto your gun instead of the void.

Would there also be potential gas and pressure problems as well, possibly affecting reliability? As in, without the 1 bar of pressure outside the gun barrel, might the gas vent too much out the barrel and not enough back through the gas tube, and cause jams?

Fucking Russians had the balls to roughly put an aircraft cannon on their craft to blast ayys

>>35036685
Yes and no. Ultimately the temperature that the gun would experience is all a function of the closest star(s) that output energy. The closer, the hotter. If assuming that you were to stay within our solar system and be around the Earth/Mars orbit areas, the gun would stay pretty warm due to proximity to the sun with respect to heaving yourself out to deep space, which would be extreme cold.

>>35031762
Correct. All rockets, regardless of being on earth, in the atmosphere, or in space, work on Newton's second Law. For every action there is an equal and opposite reaction.

Whoever stated that rockets "push off the surrounding atmosphere" is dumb. That's not how convergent divergent nozzle flows work.

The temperature of actual space doesn't really matter when you're shooting a gun - heat will build up anyway with prolonged firing, colder space will just let you shoot more before the gun overheats.

The real problem is that there is no air or convection currents to help cool down the gun, which means that heat dissipates only through radiation, which takes relatively forever compared to air cooling.

>>35038704
What if you put an air jacket around the gun?

Like how we water cooled MGs in the first world war.

>>35038704
True. And regardless of a cooling system, the heat is just being transferred to something else. A water cooled jacket keeps the barrel cool, but the water then needs cooled in order to keep cooling the barrel.

So then, what cools the water? And then once the water transfers all that heat, what then cools the water cooling medium to allow it to keep cooling the water to in turn cool the barrel.

On and on. Might be an issue here.

>>35038709
It's the same - in vacuum, all heat has to leave the object via radiation. You could surround it with a water jacket as well, but you'd just delay the inevitable, as all the water will heat up eventually, and dumping the heat of a fuckton of water takes much longer than dumping the heat of just a barrel. Luckily, black body radiation is proportional to surface area, so you could have the water run around a radiator with fuckhueg fins with a massive surface area and it'd help cool down your gun faster.

If we want to get into air jackets, you could just hook it up to a massive compressed air tank and expand the gas around the barrel then collect it in a second, less compressed tank, so that the expansion of the gas itself would cool down the gun, but eventually you'd run out of air, and recompressing the air will naturally heat it up.

>>35035983
>a glorified upgrade kit.
.... no shit. Hence the -a1 part...

>>35038737
Fins work great here on the planet, but they use a combination of both convection/conduction and radiation with the surrounding atmosphere. In space with only having radiation, the fins would literally have to be FUCK HUGE.

However, fuck huge fins and the support structure would have a lot of mass, and that could in turn solve the recoil issue. You would still need an attitude dynamic control system of jets, reaction wheels, etc to maintain control of everything though.

In the end, you could make it work, but the support system of the gun to allow it to continuous work would dwarf the size of the gun 100 fold in order to maintain control and heat dissipation.

Also, if in orbit and firing in the direction of your trajectory, without a solid propulsion source, you would literally knock yourself out of orbit and back to the surface of the planet through firing the gun.

Yes, it will overheat a lot faster.
No, the absence of atmosphere will have no effect on the cycling - almost all the gases used for that are tapped way before the bullet exists the barrel.

But space is nothing you silly filly. So yes, nothing is absolute zero. You cannot have an average amplitude without atoms to measure. Yes, space is not a perfect vacuum but it might as well be.

Air-cooled means the air around it absorbs the heat out of the metal.

Liquid-cooled means the liquid literally takes the heat out of the metal.

In a vacuum, there is nothing to pull that heat out. The thermal radiation has to have a medium for which to travel through.

The sun's core is constantly undergoing fission or whatever the fuck it is, hence the fuckoff temperatures. Eventually it's gonna cool off though, after many millions of years, part of the natural life cycle of a star.

Man, this is giving me a scifi boner, because no matter what you think of it, all of this WILL be eventually real, even if it takes a couple centuries more to fully into space operations
