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.
A sabot (UK: / s æ ˈ b oʊ, ˈ s æ b oʊ /, US: / ˈ s eɪ b oʊ /) is a supportive device used in firearm/artillery ammunitions to fit/patch around a projectile, such as a bullet/slug or a flechette-like projectile (such as a kinetic energy penetrator), and keep it aligned in the center of the barrel when fired.
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 ...
The M829 is an American armor-piercing fin-stabilized discarding sabot kinetic energy penetrator tank round.Modeling was done at the Ballistic Research Laboratory at Aberdeen Proving Ground, [1] which was incorporated into the Army Research Laboratory in 1992.
Armour-piercing fin-stabilized discarding sabot (APFSDS) in English nomenclature, alternatively called "arrow projectile" or "dart projectile" (German: Pfeil-Geschoss, Swedish: pilprojektil, Norwegian: pilprosjektil), is a saboted sub-calibre high-sectional density projectile, typically known as a long rod penetrator (LRP), which has been ...
Projectile weight (including sabot): 5.9 kg; Projectile weight: 3.9 kg including 2.9 kg and 0.27 kg tungsten carbide plug; Muzzle velocity: 1785 m/s; Muzzle energy: 6.2 MJ; Penetration: 400 mm at 0° at 2000 m, 150 mm at 60° at 2000 m
Sub-caliber armour-piercing discarding sabot projectile. Here seen with and without its sabot as well as its internal tungsten core. The most traditional way to fire sub-caliber ammunition is to fit the projectile with an expendable sabot. The sabot is a device which fills out the missing caliber when the projectile is fired and then leaves the ...
Before this, primitive wooden sabots had been used for centuries in the form of a wooden plug attached to or breech loaded before cannonballs in the barrel, placed between the propellant charge and the projectile. The name "sabot" (pronounced / ˈ s æ b oʊ / SAB-oh in English usage) [1] is the French word for clog (a wooden shoe traditionally ...
