@Mrking5555 The reason you have the sabot petals is to keep the penetrater(sub projectile) centered inside the guntube. Since the penetrator is considerably smaller than the diameter of the tube,the sabot petals are around it therefore making the petals plus the penetrator a projectile.

Hey!
Nice animation, but:
Where is the CONSERVATION OF ANGULAR MOMENTUM ???
Check the sabot's petals motion...
-
There is some rotation, its needed for stabilization, even with fins.

what to do with 5 pieces from this missile
-
wow!!
-
During the detonation of the propellant, the pressure is given to a much greater diameter/surface. This munition is a 120 mm tankround at firing, during flight it is a 45 mm tungsten steel penetrator that flies almost 2000m/sec. Thats very much kinetic energy. The abbreviation means something like: Armour Piercing Fin Stabilised Discarding Sabot, mostly followed by an 'T' which stands for tracer.
-
why is the outer cover on the round there to begin with if its just goin to fall off?
does it help "fling" the round or something?
-
@lalalman2 thing is, once the length to diamiter ratio is high enough, rifling won't stabilize the round any more
-
@DaniusCaesar hate to tell you, but what you've shown is the rotation you would find in a fully rifled gun, although, i agree that a smoothbore will produce some rotation
-
APFSDS's looses much of its energy if it rotates. Thats why smoothbore guns are used.

I'm pretty sure that even smoothbore guns still got SOME rotation... ofcourse, much less than a rifled gun, but still has some.

Actually there's no rotation at all.IF there was rotation,it wouldn't need the fin stabilizers
lalalman2 4 years ago
No, you are wrong. There is SOME rotation anyway.
DaniusCaesar 4 years ago
Rotation will result in an "O" shaped pattern in flight.Smoothbore rounds with fin-stabilizers are on a straight path in flight.
lalalman2 4 years ago
yes. you are right
DaniusCaesar 4 years ago
Unfortunetly I don't. Actually, any real APFSDS slo-mo will be great. If you find something, post it here also.
