What's a good way to classify railguns?












2














Most weapons and artillery are split by bore diameter, e.g. naval rifles of 203mm, 406mm etc.



Railguns and coilguns probably won't be classified the same way, I think. Cause if multiple models use a 25mm slug or what have you, but they perform differently, what's a good way to separate them?



Muzzle velocity? Like a 2km/s railgun versus a 5km/s one? Or input energy? That then puts forth what's a "realistic" number to power a railgun? Output energy/impact energy have the same problem.

Gauss




The gauss, abbreviated as G or Gs, is the cgs unit of measurement of magnetic flux density (or "magnetic induction") (B). It is named after German mathematician and physicist Carl Friedrich Gauss.1[2] One gauss is defined as one maxwell per square centimeter. The cgs system has been superseded by the International System of Units (SI), which uses the tesla (symbol T) as the unit of magnetic flux density.[3] One gauss equals 1×10−4 tesla (100 μT), so 1 tesla = 10,000 gauss.




I would say the best way to rate a railgun is by its Gs output.

[ammunition diameter] by [exit velocity]



Essentially, you notate the diameter of the weapon's accommodation, and then notate how fast it can get a slug of that size going. That latter would probably be a range of velocities, given that different lengths of slug will take different energy inputs to accelerate.



Also consider if you want to be able to shoot to wound instead of shooting to kill. Chemical propulsion doesn't allow for that, but a railpistol might.

Ammunition diameter x ammunition length x launch velocity, also including muzzle energy for those who don't want to work it out for themselves. They'll almost all be Armour Piercing Fin Stabilised Discarding Sabot (APFSDS) so that need not be mentioned unless different in some way, e.g.:



5x50mm 5km/s 98kJ Steel



This could be a man-portable crew-served tripod weapon or vehicle mounted railgun firing steel flechettes



Or, a more terrifying ship-launched:



50x1000mm 7km/s 919MJ DU Guided



Which would be a depleted uranium flechette with a guidance package used for bunker busting.



Or a tank-launched:



20x400mm 4km/s 19.2MJ DU



That pretty much gives all the information that anyone with any knowledge of ballistics would need to work out the terminal effects of the round and its flight performance.

            A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

            Image
            0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{...
