is a coilgun (gaussgun) better than a railgun? Answered

i am writing an essay comparing and contrasting a coilgun and a railgun. i know the differences between the two but i am in need of outside opinions on what is a more effective tool.

Hmm. i'm no expert on either, but as i recall there is no real superiority of either. Coilguns have some advantages over railguns, but railguns are more efficient packing a bigger punch.

If i were to make a guess i could see railguns taking over from Cannons/emplacement where as coilguns could end up replacing firearms. So which is better would depend on the purpose.

Again don't take my word for it, just making a guess based on what i know.

thank you for that Nighter3D. i have tried to find some clear information on both, but it is nearly impossible to find at least three articles that come to the same conclusion.

Makes sense. This is experimental technology that hasn't been fully figured out yet. Neither coil nor rail-guns are anywhere close to being fully feasible in any serious way, right now we mostly see experimental setups and proof of concepts (like the many little coilguns seen here on instructables).

Maybe years from now there will be proper comparisons possible with coilguns being pitched against railguns, or maybe as i suggested you will find both heading in their own direction. who knows!

one thing i found out is that coilguns are better in a smaller configuration. Railguns are better in a large scale application, like the naval cannon sized one that the U.S. Navy is testing.

I think that as of right now the rail gun is the more effective tool. Since we do currently have working rail gun's capable of doing actual damage, but don't yet have any effective coil guns. I will say that if we were to pretend that both weapons were fully developed the coil gun would be more portable and therefore slightly more usable.

We DO have railguns capable of doing real damage. The US Navy has had a development project running right now, run by British Aerospace.

Here is a video of one of the prototypes in action.

Rail wear is the main issue limiting deployment. Utterly insane currents are involved.You will see the projectile is a sabot round.

Railguns pack more punch, but are a lot harder to get right. There is a lot of real work on kinetic energy weapons, and the serious stuff is all based on railguns. Coilguns are intrinsically limited by the inductance of the coils
