Thanks for that Kurt, my error was in presuming the forming of the charge
was actually part of the damage causing effect of a HESH round (i.e. the
kinetic energy effect of something slapping into the side of a vehicle like
a large cowpat!), and not just a part of the process leading up to charge
detonation. I presumed a HESH round used chemical energy to impart a kinetic
effect (if you understand my mud-clear description!) and thus any velocity
imparted is helpful. . not often I'm right but I'm wrong again! |
