I am probably wrong, but I didn’t think rail guns had any recoil. The video simulations I saw showed the projectile gathering speed along the rail until it reached the end.
Assume a ‘barrel’ 10 meters long, an exit velocity of 2400 meters per second (just over Mach 7 at sea level), and a constant acceleration while in the ‘barrel.’
My cocktail napkin says that it experiences 28,800 G’s during the 1/120 second it is in the ‘barrel’.
Well, since its relying on electromagnetism and not gunpowder, I suspect the kick is far less than one should suspect. At least as far as I understand the technology.
You aren’t directing an explosion, that wants to expand in all directions here out a nozzle here, you are progressively moving a projectile with magnetic force faster and faster over a short distance.
Think of it more along the lines of a SUPER roller coaster magnetic launcher, than a standard gun. Just far more powerful, and extreme.
