  • Believe it or not, those are gigantic, heavy gauge coaxial cables folks. If they weren't, they'd have a lot of wasted stray inductance. The force on the projectile goes as 1/2 * L * I^2, where L is the instantaneous inductance in the gun, and I is the current. Any OTHER inductance in the current loop between gun and supply is wasted, but DOES serve to impede the rise time of the current pulse. They talk about the cables in several of the white papers on this thing (Dahlgren's 32 MJ gun)

  • @psychohitler thats wat she sed, sorry couldnt help it

  • And who said science aint cool.

  • either way,thats a ridiculous load of rubber lol

  • Not hoses, cable's to the capacitor bank.

  • wats with all them hoses...damn....i think there's enough to make 4 sets of car tyres there...

  • Lots of cables at the gun! Perhaps they should better use two big copper bars instead of a hundred normal cables.

  • Not really molten...a part of it evaporates...when it leaves the barrel, there is no more plasma. Only flames ;-)

    Plasma is very unstable...

  • When it leaves the barrel it is molten and it turns the air around it to plasma.

    Very Cool!

  • It has to be pressed in to make contact with the rails. Tight fit is needed so that it maintains contact with the rails when it is fired. This is a research platform, loading and firing is all about the materials and what works and what doesn't work.

    Black powder? How much powder would it take to push 3.52kg at 8200 feet per sec? Think about it.
