Post your designs here!

That railgun doesnt work. i copied it down exactly. yours has an accel of 5e+008, mine has an accel of 6e+008, with copying every value i saw exactly. the only thing i can think of is that the came rounded up some fine tuning adjustments, so i dont see the EXACT values (dont to the tiny digits). mind posting the code ?

After designing several coilgun and railgun in the game, it seems that coilgun has consistently far lighter weight than railgun of similar spec.

However, coilgun now need to use nickel iron molybdenum just to have reasonable stat, because iron is crap now.

So the price of coilgun get jacked up, especially for heavy projectile coilgun.

Buttt, with the lighter weight of coilgun, they used less fuel to get carried around than railgun.

So it's a matter of balancing price and mass again.

I STILL CANNOT FIGURE OUT HOW TO MAKE PROPER COILGUN WITH MORE THAN ONE STAGE!!!

Obviously so. The worst instances include zero mass, zero stiffness spacers, and then also 'cheese' the total mass calculations. Adding any mass to an armature should increase the gun stresses from increased forces to obtain equal acceleration and should have no benefit to the local conditions at the rear of the short circuit which is the significant part of the rail-armature conditions (even if you had a 50m long spacer IRL with zero mass), the second short circuit exiting the muzzle would be irrelevant to the armature.

That said, I have obtained 141km/s from a tolerably accurate if impractically heavy railgun with a solid armature with no payload, which approximates the medium/large target accuracy levels of the old 134km/s equivalent, so high performance is possible at a cost. (Small target accuracy ranges are lower, even for 'perfect' weapons than the earlier values).

A problem with the new turrets is they want to broadside on the broadside so I made a tiny laser, I cannot extend the armour up to limit the angle at which you can fire into the optics, so only two inches of armour
Edit: no you can't see it because PB threw an error when I tried

I think the problem with multi-stage coilguns is that the later stages need faster rise times than the early stages, so they should be fewer turns of larger wire, or have higher voltage capacitors.  But we're forced to make them all identical.  Rise time gets handwaved away with line-powered coilguns, though.  And resistance seems to be a lot less of a handicap than for railguns.

I was able to make this thing:



Efficiency is poor compared to capacitor railguns, but it's not super heavy, and the amorphous carbon barrel makes it very rigid.  Also the rounds are super-thin needles, so they have extreme sectional density that should give good armor penetration, assuming that's modeled.

You can improve efficiency and muzzle energy at the cost of weight and muzzle velocity by increasing the projectile mass and diameter and the barrel armor thickness.

Super Capital Laserstars are awesome.

1.77TW of waste heat? Missiles won't have trouble finding that thing. Though they might have trouble getting near it lol.
