Also, did I mention this is going on a two metric ton suit of armor? Recoil wont be an issue up to insanely high rates of fire, such as 3000rpm, what with the (relatively) small rounds and very heavy apparatus.
Edit: I did the math and that's enough to make the suit accelerate at about 1-1.5m/s backwards, discounting friction. :O
edit3:
So the joules per bullet is (1/2)mv^2, and the average bullet mass is .02-.04kg, and say its accelerated to 3000m/s. That gives each bullet a kinetic energy of 135000 joules.
The energy is imparted in 1/3000's of a minute, or 1/50'th of a second at 3000RPM. So 135KJ per 1/50th of a second is 6.75MW (joules per second), just for the coilgun firing mechanism, assuming perfect reliability and efficiency.
aww ye math
(man that was a clusterfuck)
edit4:
How much power could a miniature aneutronic fusion reactor output? A MW isn't a small amount of power...
Energy use will decrease exponentially with a smaller rate of fire, too...
Yeah. Depends on how the system works. Is it firing every next barrel or is it firing every 4th/3rd/5th barrel pass for cooling and effectiveness? Because these things are pretty important. The obvious parts you can do in your head.
