Hydrazine Sub-machine gun: Impossible or possible?

Post Reply New Topic

Hey, I came up with this idea to use hydrazine as the propellant for a sub-machine gun. I don't know if it's possible, but I want to know.

???

What sort of sub machine gun ??

Doesn't seem very likely tho.

For those who don't know, hydrazine is a fuel used as liquid rocket propellent. It is very possible to build a machine gun using such a fuel, and there are several ways of doing it. I saw an improvised jet engine built with a turbocharger from a junk car. If a high enough exhaust velocity is created, it is possible to introduce projectiles into the exhaust gas stream. Another way to accomplish the task would be to feed hydrazine and oxygen into a combustion chamber and provide an ignition spark once a projectile is introduced into the barrel. However, hydrazine is hard for an average person to obtain, is highly toxic, and expensive to boot. If I were considering building a liquid fuel type of machine gun, I would probably use something more common such as gasoline (petrol), race car fuel, or airplane fuel.

Why not a railgun?

the trouble is that hydrazine is highly toxic.

wiki mentions use as an artillery propellant but it seems they have an inherent issue with misfiring.

The unclassified paper that wikipedia links to has lots of information.

It seems that it is possible to do but the guns have a nasty habit of blowing up.

Toxic fumes would make it a poor choice for propellant in small arms.

Well, the guys in my story are wearing futuristic military spacesuits, so I think the fumes would not do a thing. Also, their used only in space.

I can almost guarantee that if you even attempted to build such a dangerous sounding gun you'd have a hard time writing your book without arms!

Oh, if they're in space, it might be ideal, since Hydrazine is used in the smaller thrusters on spacecraft, so one would assume that it's suited to work in space... if you combined it with a projectile that was designed specifically to pierce space suits (like the spikes that let the air out of tires) you might have a winner... but a very gruesome one.

with self sealing materials it would be a rather simple fix to simply pull out the spikes.
perhaps flachettes would yield better results but accuracy at range is a concern.
