Hey all

Im trying to build a small railgun capable of launching a projectile(20-40g) to about 400km/h.

Attached is a excel file. It is a sort of simulation. Cells in red must get values from the table. Cells in Blue must be typed in by user. Cells in Green list the Current/Mass needed to acieve desired values.

This all makes alot more sense with the simulator.

Thank You!

Kind of forgot about the user friendliness.

The gun will make use of a capasitor bank. The capasitance and voltage of each of the caps can be set manually. The resistance is in a column. It seems very low, but it is assumed that between 3-6 caps are used in parrallel.
