Re: China’s Manned Military Space Ambitions

I'm looking forward to completing your training. In time you will call me... 'Master

THere was weapon in spaceThe weapon ws diasmontaled beacuse the RUssian signed some treaty that do not allow them to do so but before that it destoryed a dummy satellite proveing its effectiveness right now its proboly siting in a Russian junk yard google on that topic and you will find answer that was a long time ago eg in tha 70s

Re: China’s Manned Military Space Ambitions

I will not be surprised to see that Russians or Amercians trying to put some sort of weapon in space during the cold war age. However, would a 23mm cannon work in space? I very much doubt it. There are many conspiracy theory out there such as moon landing hoax and you cannot say it is true simply because you found 'something' with Google.

Dongfeng,

Why wouldn't a cannon work in space. I am assuming that a projectile would have a increased velocity since there is no friction around it.

I think the cannon would work better in space beacuse there is no resistance and the pulposion would still be the same gun powder as for the cannon its self is the same on as that of those used on the late MIG-21/23 agin its a long time ago and preety well documented

Re: China’s Manned Military Space Ambitions

from a physics point of view, a cannon would work. but to fire a single shell or projectile, a large of amount of energy would be needed to keep the cannon in place. remember Newton's third law of motion --> "for every motion, there's an equal and opposite reaction." or like some engineers like to say "for every motion, there's an equal and opposite government policy". but back to physics. that means to fire the shell forward toward earth, you need the cannon itself move back toward outer space with the same acceleration as a function of its mass. F=ma. and it order to keep that cannon in the same location in space, you'll need a rocket or booster to constantly pushing on the cannon to adjust itself so that it doesn't fly into outerspace. and that fuel for boosters will be expensive and hard to ship up, and needs a lot of it if considerate damage is needed by the cannon.
also cannons currently depend on gunpowder. now gunpowder is just a chemical compound that's extremely explosive or from a chemical point of view, oxidizing. which means oxygen is required for it work. i'm not a artillery man, ask Golly. but from theory, if there's no oxygen, your cannon is good as useless. and oxygen is just one of those things missing in outer space.
also the earth's atmosphere is very good at melting things at reentry. so you get a small shell, chances are by the time it reaches the ground it would already by burned into its fundamental elements. so no damage could be done. unless you can thrown something the size of a building onto the planet.
of course other oxidents are also used, ammonium nitrate and potassium nitrate. but still need the oxygen to get it all started as far as i know

Re: China’s Manned Military Space Ambitions

that cannon has it own oxygen supply so that wont be a problme also the whole system is a experiment and incredible crude also the target would be American satellites so the melting paart is not a problem

Re: China’s Manned Military Space Ambitions

once again, i'm going to go back to fundamental sciences to answer your question.
1 C(s) + 1 O2(g) --> 1 CO2(g)
that means for every mole of carbon combusted, one mole of oxygen is needed.
this is a unbalanced equation of the reaction of potassium nitrate with sulfur, notice that there's much more than just boom sound involved.
KNO3(s) + C(s) + S(s) -----> N2(g) + CO2(g) + K2S(s)

Re: China’s Manned Military Space Ambitions

as I menationed before the whole thing was a experiment altho a dummy satellite was destoryed nothing more was head from them later on the cannon was dismontaled the thing probely dident work well or the russian wondent have signed the treaty you dont need uch pulposion beaqcuse you just have to put the shell in odrite to collide with the target

Re: China’s Manned Military Space Ambitions

Anyone here heard of 'rods from God'? It is an idea to simply "drop" tungsten (will not melt in reentry) rods from orbit on any target of interest. Darth sidious said the supposed russian cannon would be used for attacking other sattellites, not for firing earth bound rounds, so such a system would require some sort of propulsive force, ie an explosive chemical reaction. If however, one wants to rain shells or ordance on earth, no need for the gunpowder. Just a small force to push the projectile in the right direction will lower its energy enough to fall back to earth. A tungsten rod "dropped" from space will have more kinetic energy upon impact of the earth's surface than any artillery shell or guided missle in today's arsenals--the destructive force would be scary.

Anyway, let's hope no one deploys those since it would just cause another huge arms race, but there are some very interesting ideas for the weaponization of space.

as a matter of fact...a 23 mm cannon couled be fired, and it would fly forever in space until it hit something, or got sucked in by a gravitational force. as long as the opearting mechanism was actually in a pressurized cabin, a gun could fire in outer space.
