Have you checked those links Mikey? Now do you realise you were incorrect to
say a "DU is referred to as a heat round"?
I see you confused HEAT (high explosive anti tank) and heat as in thermal
energy. However, a "heat round" means one thing and one thing only WRT
OK, done. To the denizens of sci.physics. Does an anti tank shell which
consistes of a tungsten penetrator use kinetic energy (i.e. a product of its
weight and speed) to penetrate armour, or is the chemical definition of
"kinetic" applicable here instead? Myself, I am 100% sure it is the primary
definition of kinetics, i.e. it is the combination of the projectiles speed
and weight (but mostly speed) that applies here, rather than "The branch of
chemistry that is concerned with the rates of change in the concentration of
reactants in a chemical reaction"
Whilst no one is disputing considerably thermal energy is produced in such
an event, the solid DU round punches through the armour due to its kinetic
energy, it does not "melt through the mettle (sic)" due to some chemical
reaction. true or false?
1) What chemical reaction is that?
2)I certainly never claimed that heat woudl not be produced! Please cite
where I did. I merely claimed a solid DU round uses kinetic energy to
defeeat armour, it does not "melt through the mettle (sic)". I merely
claimed a DU round was seperate and distinct from a HEAT (high explosive
anti tank) round, not least because it contains no explosive. Apologies if I
confused you by not always using upper case for "HEAT", but "heat round
"means only one thing in terms of tank ammunition. Seeing as you were
attempting to lecture me on what a DU penetrator was, I assumed you woudl
know these basic terms.
I have never denied that heat woudl be produced by the imapct, merely that
it is not heat which defeats the armour when it is hit by a solid DU
penetrator, any more than it is heat which causes a dart to stick in a
Well, he who laughs last and all that...
Is this supposed to be humour?
Please learn the distinction between the acronym HEAT and heat.
Already done. Crossposted to a militarygroup too, for good measure (though
it is a moderated one)
Already done. For anyone in the military group who is interested, Mikey has
been claiming for a year or so now that a DU penetrator (e.g. APFSDS) is a
"sort of HEAT round" which "melts through the mettle (sic)" of whatever
metallic object it is fired at. My osition is that e.g. APFSDS rounds uses
kinetic energy to penetrate and are very different from HEAT. I would accept
"melts through the mettle (sic)" as a slightly innacurate term for what a
shaped charge does, but that's beside the point.
I have. I even provided you with links to descriptions of tungsten/DU
penetrator rounds and HEAT rounds. You have apparently chosen to ignore
HEAT means High Explosive, Anti-Tank. It referes to a type of ammunition .
how many more times?
What the..? Whenever did I say this was the case? YOu are confusing the
acronym HEAT with heat again. Even so, heat (as in thermal energy) is NOT
what defeats the armour when it is hit by a solid DU (or tungsten)
penetrator, kinetic energy does. I assmue some of the is kinetic energy is
converted to thermal energy on impact, I never said it wasn't.
Please indicate how that is supposed to be proof of me "supporting
