Still, air pressure calcs, that are basically a more complicated version of the KE-to-speed calcs, are generally accepted.Īnd I believe it should be even more obvious in case of futuristic projectiles. That and super strength + Shounen-style artistic license often makes them pretty untrustworthy. KE calcs for speed are rarely used because the results are rarely consistent with other methods. Some of them are just tend to be less reliable than the others. A pretty rare situation but regardless it can happen.Īgain, there's no such thing as absolutely not allowed method. Yet there are cases when we have an official statement on the said character's reactions, which in turn allows us to make a proper calc on someone who managed to blitz that guy.Įven the infamous calc stacking is feasible in verses with enough consistency on that regard. They cannot be done unless certain conditions are met.įor example calculating speedblitzes for superhuman characters is generally not accepted. Just some of them are less applicable to measure feats. I'm lazy so I'm just putting these into the Kinetic Energy Calculator.įitting for a somewhat advanced yet still an ordinary projectile.Ĭlick to expand.Actually, there's no such thing as banned calculation methods. Which is according to the wiki has the projectile weight of 425 grams.īy using the square-cube law, we can guess the projectile weight of a similar but 36mm diameter shell: It's a 30mm Gatling Gun which incidentally has an infamous round with depleted uranium penetrator, the PGU-14/B. To our luck, real world already has something which is like the little brother of the Assault Cannon, the GAU-8 Avenger: That'd be difficult without knowing the shell's internals. To know the velocity of those 36mm shells we'd need to know their weight, first. Thankfully this is a calculation blog so you're going to get the answer very soon. So the Assault Cannon's projectiles should be at least in the similar range, as well. More importantly, modern APDSFS shells are known to be hypersonic in speed. That's roughly 1/3rd of the energy of modern APDSFS shells.Ĭonsidering those are in the 120-125 mm caliber, the Assault Cannon does pretty well here. The previous calc showed that the Assault Cannon's shells possess 2.186 Mj of energy.
