This is the current design for the revision 2 of the railgun.
The revision 2 Railgun will incorporate several major changes, and several minor changes.
-The capacitor bank will be expanded by 22 capacitors, giving a increase from 5616 joules to 12480 joules, at 400 volts. Peak energy, with capacitors set aside for coilgun and surge voltage, will be 16980 joules. With calculated (RC time constant) capacitance, actual energy will be ~ 12kj.
-The bus bars are reconfigured to use minimal material, and have minimal resistance. They will be 1/2″ thick aluminium (due to cost restrictions). Total bus bar length will 8 feet, versus the 11 feet for the current much smaller bank.
-8x 2″x2″x1″ NdFeB Neodymium magnets (grade N50) will be used for a permanent magnet augmented railgun. The field strength of these is large enough to be beneficial even with 100,000A current.
-The injection valve was retrofitted with a solenoid, which will allow for remote triggering
-The rails will be silver plated, with the cool-amp silver plating powder.
-In an effort to minimise resistance, the cables have been eliminated.
-a analog pressure sensor was connected, and a comparator circuit (point to point solder) which is set to trigger at 50 PSI.
-The charging will be a HF transformer with a flyback core, for better voltage level control.
Some things I plan on trying out:
- 3″ square pieces of bullet proof glass will be shot, hopefully getting fractal patterns. This will be useful for comparing power, and seeing the orientation of the projectile when impacted.
Construction begins on arrival of the bus bar.
