Actually the train example is a bit flawed as the train motions is mostly irrelevant. The strikes come from outside the train frame of reference -- clouds not necessarily sharing the trains motion. A better example is that two explosions occur simultaneous aboard the train according to the train...

Practical Superconductors 101 Well do you think it is practical with Type IIs? Feed me some detailed knowledge on something I am not that familiar with. Really I would think price would be what would make this a weapon of the distant future (20+ years).

Room Temperature - maybe maybe not Can you afford military prices? Well actually technically high temperature superconductors are what is known proven state of the art. And they would be usable with a good liquid nitrogen supply. On the other hand you did notice this might be a Bell...

You probably need to readdress whether the old reasons for cylindrical ammo over ball ammo is still valid. (1) Primary reason -- Cylindrical ammo gave a much better gas seal than spherical but irrelevant in this case (2) The aerodynamic lift effects of spinning cylinder is more easily fixed...

Recoil is a tricky question in that they are obviously talking subjective recoil. Further for physics we are asking a question of momentum and not kinetic energy. So given two counter-rotating centrifuge systems which release projectiles with opposite momentum essentially in synchronization...

And there is your problem -- you assume a mechanical rotor. Is there a rotor in a Cyclotron? Nope. So what if you applied some room-temperature superconductors to levitate and spin only the bullets themselves?

Weapons almost never sustain peak fire rates. Most mechanical weapons systems must stop after a few hundred rounds at peak rates due to heating effects - anything from thermal expansion effects to incipient barrel damage (phase changes in metals). Think firing in bursts. Here the limit is...

But what if the bullets are spun by a pair of counter-rotating superconductor electromagnets? https://www.physicsforums.com/images/smilies/love.gif :!) Then the only moving part is the bullets. And I suspect the chamber quickly becomes a vacuum during fire. Basically this is a Gauss gun...

Easy Peasy mate Took me maybe 10 minutes figure this one in the rough. counter-rotating room-temp superconductor electromagnetic centrifuges with center feeds. https://www.physicsforums.com/images/smilies/cool.gif :cool: This balances effects of lost angular momentum by paired...
