'Electric armour' vaporises anti-tank grenades and shells

Isn't there the possibility that the capcacitors hold enough charge for several shots?

caps aren't like batteries. they discharge all at once.

not if the connection breaks before they're fully discharged.

caps don't discharge instantly, the potential across them decays exponentially and the higher the resistance the longer it takes the potential to drop x much.

It may only take a small portion of the capacitors total charge to vapourise the copper from a single rpg. One the copper is vapourised the connection will be broken leaving plenty of charge left.



The other option would to be to have several capacitors so you can flip to the next one after each shot.

hmm... a capacitor to charge a capacitor. might not be a bad idea. an array of capacitors that charge the hull when the hull is discharged. buffers, as someone else had mentioned.
 
hmm it does imply in places that it's powered by charge stored in a seperate capacitor connected to the armour. Doesn't seem to clear actually.

The article's not supposed to be clear btw. The exact working of the armour is still highly classified. Reading between the lines of the articles should give a couple of clues though.
 
Truthfully, the amount of energy needed to vaporise the copper shunt isn't likely to be more than the batteries and/or onboard generator can handle.

Or there are several banks of caps. These things are relatively cheap after all.
 
No, but I stayed in a Holiday Inn Express...


(probably makes no sense if you don't watch US commercials)
