Rail Gun (energy weapon instead of solid)

Post by Soladrin » Wed Jul 08, 2009 7:29 pm

Well, following realistic Rail Gun testing and theories, if properly made, a rail gun's slug will only remain solid for a fraction of a second before turning into plasma because of the friction with air. Thus, real railguns could be considered more of an energy weapon. This way you get an entirely new twist on a much used sci-fi weapon. ;)

Any weapon is an energy weapon, kinetic, electromagnetic or otherwise. But, in-universe, a lasgun would be an enwergy weapon, as would a melta and plasma.

Railguns may melt to projectile, but it still fires projectiles, possibly even a missile launcher. But the rounds are expelled through the barrel/rails by electricity, so it could be an energy weapon. Don't Tau railguns have submunitions with them?

But yes, since the rounds are heated like a melta gun, them they're probably energy. Refer to the cover of the Last Chancers novel

Rail guns fire rounds/projectiles.
Small ones, big ones... depending on what you want, rail"cannon" or railgun.
Either way, railgun fires something solid with great velocities.
It doesn't have to fire a shoot at speeds that dissolve it to plasma, but the idea of railgun is to fire a round at speeds of mach 2, 3 or 4 depending on how much energy you can or want use to fire that shoot.
(dunno, what's the limit of speed when the round and air around it burns to plasma... but to destroy a line of soldiers, pierce trough a tank or building wall all you need is round fired at mach 2-3 and it doesn't have to be heavier than 0.15kg if it's shaped well to have great aerodynamics and if it's piercing point is made of something really strong, like titanum alloy needle or diamond needle around which is depleted uranium.)

dunno if you understand what i want to say ... if you want me to draw it i can do it and post the link for you to see.

i doubt mah 2-3 is enough for that, and also, we an reach mach 7 already :P

Oooh yeah :D
we can :D
(wouldn't it be wonderful to have a walker/battlesuit/tank with dual railgun :D awww so adorable :D )

intresting thing i heard

using a air presure canon some US scientists fierd a marshmallow at around mack 8 and it punched thrugh around 20-30 of armour plate

I hardly believe marshmallow could still be in one piece at mach 8, air friction would tear it apart before it acctualy leaves the "cannon" tube.
All above mach 5 is hypersonic speed and for that you need stuff to be made of highly durable matterials (Cooled nickel-titanium skin, covered with Silicon thermal tiles) and to be very "aerodynamic" for such conditions cause air gas molecules act completely differently when something moves trouhg air at that velocities if you want it to "survive" till it reaches it's target, if fired from railgun.

anyway, my point here is, a rail gun wouldn't do projectile damage like a slug, but its like being hit with high speed plasma or some other heat source thingybob XD

Plasma does damage by heat. It's almost like gas.

Ek=0.5*m*vˇ2
Ex= kinetic energy, m=mass in kilograms, vˇ2= square of speed in meters per seconds.
From kinetical energy comes the damage of rounds fired by railgun.

As for anything fluid like (gases, plasma, liquids) ... it would be hard to achieve it cause it does not have specific form.

But here is an idea!

The gun you proposed would be something like plasma gun (just little bit bigger than rail gun and you'd have to choose to shoot or to move, or to mount it on vehicle or battle suits/power armors, just like the case should be with railguns )

High powered lasers ionise and heat up certain quantity certain matterial (something heavy and metalic to have bigger kinetical energy when accelerated) to plasma around which is in the same moment created complex magnetic field to keep it in spheric or elyptical shape.
Then the plasma sphere/elypse (it's small, like... 5 to 6 cubic centimeters) is fired with magnetic accelerators which work simmilar to railguns magnetic accelerators.

That plasma package is accelerated to hypersonic velocities of mach 6, 7, etc.
It has small mass, therefore small kinetic energy, something like a sniper bullet (when compared to railgun shot) but it has HUGE!!! temperature which melts trough anything.

Why so high speeds??
When plasma leaves the tube so do magnetic fields go away, they simply stop existing, so if the plasma does not reach it's target in enough short time i will disperse as gas. But at such speeds air-plasma friciton keeps plasma from dispersing by generating new plasma by slowing speed of original plasma particles (also reducing plasmas temperature) while it's still very high kinetic energy keeps it going towards it's target.

It comes to target, hits it, punches trough it and burns trough it too.
If it's metal armour, it punches into it (not trough it) and gives it's high temperature (above 5000°C ) to it which causes metal to melt, burn etc., and plasma also may ionise the metal for short time which may cause small electrical discharges inside the vehicle damaging it's internal electrical systems for short time or even permanently.

The entire process must be done in less than a second :P

That is what can be done with plasma... if you look at it from sci-fi "realistic" viewpoint.

I hope you like the idea :)

I see this as a weapon for our trusty friend the sniper. Super strength, ignores cover and armor, highly accurate, single shot. Good vs enemies in heavy cover. Good vs vehicles.

It is good vs. anything. If it doesn't pierce trough target in 1st shoot then it will definately end it in second. Both raildung and "modified railgun/plasma gun"

Ofc, on vehicles you can mount bigger versions to do "template damage" if it hits units like infantry or "single unit" damage if it hits vehicles like tanks.

These "plasma guns" should be something like "relics/artifacts" cause of advanced technology for creating plasma, magnetic fields, materials used in it etc.

While railgun is much more simple with [far more] bigger range but... i'd say it has relatively limitet capability for destroying something armored, it will pierce trough it but will not melt it down from inside.

So when you compare
Railgun = big impact strength, big range, big armor penetration
"plasma gun" = Lesser impact strength [lesser kinetc energy of plasma than of railgun round], lesser range [but still very big], terrible damage to armored units cause it melts, burns etc.

Yet... both weapons kinda instant kill anything infantry like. Heavy infantry (battle suits etc.) has chance to survive railgun but not the "plasma gun" which burns it from the inside when it hits it, vehicles have far more better chances to survive railgun hits cause it simply pierces trough them (may maim them but not destroy) "plasma gun" on the other hand... well... as in previous case, burns it from inside, melts it etc. etc. (and as i said, if not in 1st then in 2nd shot it will definately destroy it's target if it's vehicle)

Well it like saying a cannon ball isn't as effective against infantry as it is against cavalry. It is effective against both, but it is more effective against cavalry in points.

It could kill one man or maybe two in a lucky shot but it was designed to combat tanks.

With weapons like MetalStorm in development, I'm not sure how viable a rail gun would be to mass produce. The weapons itself is expensive, then replacing the spent barrels and ammunition.

Plasma could more than kill a man - it blinds and incinerates groups, but they need to be in close proximity to one another to all be killed. The sheer heat from the round would gibe burns to any nearby infantry.

Also - wouldn't a plasma/rail gun round make a sort of thunder-like crack from the super heating of material/air? IT happens with lightning, so just wondering.

For railguns the best would be to have line template. Everything in line will get pierced.
It's something for taking out specific units, Comanders, leaders, heavy infantry, specialist units etc.
(and it should be expensive and it's shoot or move weapon, cause it's big and heavy + power generator for it you need to carry unless it's mounted on vehicle [i'm gonna post artwork after i get over with my exams])

As for "rail-plasma-gun"
Yeah, both railgun and "rail-plasma-gun" would create a line of plasma which is collored like a lightning, it just goes like a straight-forward line (unlike the real tunder lightning) and that light is very short lasting and does not do any damage of what so ever.

"rail-plasma-gun" wouldn't have line template cause it doesn't have such piercing power but it's heat is devastating to vehicles... and you could use very small template for it.
Like, big template for some awesome bombs, rockets etc.
small template for hand grenedes, molotov cocltails etc.
very small template for that "rail-plasma-gun" cause it's heat may! incinerate 2 or 3 man from entire squad from heat dispersion, but 1 man goes down for sure after being hit by it :)

Yet... it's better to be used against vehicles or to burn down covers :D
Ordinary guns are not effective against that stuff :S
