Weaponized Naquadria

[mirdin1992]

.5 c?


my god, that's uberoverkill.


at those speeds, no armor can EVER stop it. it wouldn't even fire bullets anymore, anything would be turned to plasma. as if it's a superomega flamethrower.

anyway, there are 2 uses naquahdriah has:

-bullet is heavier (kinetic energy)
-bullet is radioactive.

I mentioned that the more mass the projectile has the slower the max speed will get. For 0.5c the size of the projectiles would be microscopic in size.

I should probably added a laser or something to clear the atmosphere before the firing the gun so the backlash wouldn't be so serious and get higher velocity in atmosphere without the slug causing a fission/fusion reactio as it leaves the gun.

Still a million G acceleration may be pushing it a little. Nahhh... Apophis Ha'taks the one in S1 made 10.000 Gs and the people never felt a thing.

EDIT: What about a Naquadriah/Potasium bullet?

[thekillman]

i doubt naquahdriah is the same as naquahdah, in that case.



railgun ammo would be a bad idea.


and Re: deathglider. that thing had intertial dampeners

[Cmdr. Setsuna F. Seyei]

railgun ammo would be a bad idea.

why?

[mirdin1992]

why?

Think he means that naquadriah is bad ammo because your liable to blow yourself up as much as the enemy.

[Cmdr. Setsuna F. Seyei]

how so??

[mirdin1992]

Blast radius would be most likely. Naquadah gives OOM more energy than M/AM reaction Naquadriah is like 10+ times more powerful than naquadah. So a kg of this stuff would give a low estimate of a 4500 megaton *BOOM*

[Cmdr. Setsuna F. Seyei]

it was stated on sg1 that a naquadria bomb the size of the one used on kelowna would have the same detonation force as a naquadah enhanced nuclear bomb.

so just a small amount say .5 grams shold do some massive damage to a hive

[thekillman]

the forces in the railgun would cause a detonation in the naquahdah.


even if it doesn't, there's plasmafied naqauhdah around the railgun. hit and boom

Not necessarily, no. You still need to initiate a fission reaction. For that you need either enough naquadriah to create critical mass (which is a lot; your railgun would need to be, in the very best case, the size of an Iowa-class battleship primary cannons (that's 16 inch/406mm), and the energy required for launching projectiles would grow accordingly), or insane compression (and that compression better not be achieved inside the railgun at the moment of launch). Naquadriah is not unstable in the sense that it blows up if you drop it on the floor; it's the fission reaction in naquadriah that is hard to control once initiated. You want it to proceed slowly and generate energy, and it wants to react all at once and blow your engines up.

[thekillman]

not every element has the critical mass of uranium. for all we know, naquahdriah has a much lower critical mass. which is very bad in this case, as it's also extremely dense.


say a sphere of material.

Element, critical mass(Kg) diameter of sphere (cm)

californium-249 6 9
californium-251 5 8.5


as you can see, californium has a very low critical mass. which means it's not impossible.

The critical mass is inversely proportional to the square of the density.

so if the density increases 4x, the critical mass halves. if the radius of the sphere is any indication, well, we know that Ark Bombs can blow up an entire state, making them into the MT and near (if not exceeding) GT range.
the naquahdah core is between 5 and 10 cm thick. using californium, that would mean a critical mass of a few kilograms.


406mm = 40.6 cm. so about 1/4th of those guns would allow critical mass naquahdah ammo.

100 mm guns therefore could shoot pure, refined, naquahdriah shells and have them explode.

since naquahdriah is radioactive, it's bad to use them as ammo

[Cmdr. Setsuna F. Seyei]

ok you are still talking in kilograms
i was wondering about say .5g to .5kg and insofar as radiation goes line the core with lead foil

it should be made so that only the rapid desceleration of the round should detonate the NQi core

Hmm, 100mm is a tank cannon. Or the largest existing RPG warhead. That could actually work... assuming the safe stand-off range is no more than a few hundred meters.

Radiation isn't too big a problem if the shell is properly constructed. There exist tactical nuclear artillery shells, so why not naquadriah ones?

[thekillman]

eehhm. naquahdriah radiation is an exotic form, so i doubt a few cm of lead are gonna work. for all we know, it emits gamma radiation. actually, i'm SURE it emits gamma radiation, it HAS to.

Here is the transcript of S1R15 "Singularity"

Spoiler:

CARTER
Now, potassium can be one of the most volatile alkaline metals on Earth. Combined with even a small concentration of Naquada, and…

DANIEL
That doesn't sound very good.

[The monitor shows two robot arms in small room.]

CARTER
The room you're looking at is in the sub-basement floor of the complex. It's lead sealed. Let's see what happens when we put the two objects together.

[CARTER types some commands into computer.]

DANIEL
Where are the samples?

CARTER
I'm only using a microscopic particle of each.

[The two robot arms move closer together and…**BOOM** The monitor screen shows grey snow.]

FRAISER
The reading's off the scale. Gamma and particle radiation.

DANIEL
Are we safe?

CARTER
Yeah, but we have a big problem.

DANIEL
Well, if two microscopic particles can cause that…

CARTER
Then the object inside Cassandra could cause a nuclear reaction a million times bigger.

That was naquadah and naquadriah is OOM more powerful than that.

[Cmdr. Setsuna F. Seyei]

that was only when the naquadah was detonated and not b4 so a thin layer of lead might do the trick

And btw lead blocks almost all types of radiation thats why its used to line nuclear bunkers
