The sabot component in projectile design is the relatively thin, tough and deformable seal known as a driving band or obturation ring needed to trap propellant gases behind a projectile, and also keep the projectile centered in the barrel, when the outer shell of the projectile is only slightly smaller in diameter than the caliber of the barrel ...
A driving band or rotating band is a band of soft metal near the base of an artillery shell, often made of gilding metal, [1] copper, or lead. When the shell is fired, the pressure of the propellant swages the metal into the rifling of the barrel and forms a seal; this seal prevents the gases from blowing past the shell and engages the barrel's ...
Obturating rings are common in artillery, where the steel or cast-iron casing of the shell is too hard to practically deform to provide a tight seal for the propellant gases. An obturating ring which is called driving band made of a softer material is the standard solution for that problem.
Armour piercing discarding sabot munitions were developed to increase penetrating performance of anti-tank projectiles by generating higher impact velocity.A larger projectile would require a completely new weapon system, but increasing velocity faced the limitation that steel armour-piercing (AP) projectiles shattered at velocities above about 850 m/s when uncapped.
The M1 ammo crate held a total of 1,000 belted or linked rounds packed in 4 M1 ammo boxes and the later M1A1 ammo crate held a total of 1,000 belted or 1,100 linked rounds packed in M1A1 ammo boxes. There were two .50 M2 ammo boxes to a crate (for a total of 220 belted or 210 linked rounds) with a volume of 0.93 cubic feet.
The bourrelet is normally forward of a rotating band or driving band near the aft end of the projectile. The driving band is customarily made of a softer metal than the remainder of the artillery projectile and of a larger diameter than the bourrelet to seal the barrel and be engraved by the rifling to spin-stabilize the projectile in flight.
Armour-piercing fin-stabilized discarding sabot (APFSDS), long dart penetrator, or simply dart ammunition is a type of kinetic energy penetrator ammunition used to attack modern vehicle armour. As an armament for main battle tanks , it succeeds armour-piercing discarding sabot (APDS) ammunition, which is still used in small or medium caliber ...
