Hello, as stated I'm working on a railgun. At this point, I'm in the design phase. I'm currently trying optimize the performance of the gun within the constraint of my resources.(adsbygoogle = window.adsbygoogle || []).push({});

As you may or may not know, a railgun consists of two rails short-circuited by a conductive projectile which is propelled down the rails by an electromagnetic force, in this case the Lorentz Force.

My rails, both of them, will be pure copper, 1 cm in width, 0.5 cm in height and 40 cm in length. They will be 0.5 cm apart.

The projectile, armature, will be 0.5 cm high, 0.5 cm wide and 1 cm long with a hole 0.25 cm in diameter drilled from the rear end 0.75 cm deep. This hole shifts the center of pressure behind the center of gravity, giving it aerodynamic stability. It will be made of aluminum.

To power this system, I will use a bank of capacitors. Each of them will most likely be as follows: 3300 uF (.0033 farads) at 400 volts. This yields 264 joules.

Could someone help me figure out the current, in amperes, said capacitor would generate within this circuit? The capacitors will be connected directly to the rails. Your assistance would be enormously appreciated. I can then establish how many capacitors I need in series and/or parallel to achieve the highest projectile speed possible by plugging the value (in amperes) in a few equations.

Thanks in advance for your time.
