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 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.
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.
An important armour-piercing development was the armour-piercing discarding sabot (APDS). An early version was developed by engineers working for the French Edgar Brandt company, and was fielded in two calibres (75 mm/57 mm for the 75 mm Mle1897/33 anti-tank gun, 37 mm/25 mm for several 37 mm gun types) just before the French-German armistice ...
Second-generation Chinese sabot round introduced in 1999. Initially 125-IIM acted as the export version with reduced velocity but with the introduction of DTC10-125, the DTW-125 itself became exported under the name “BTA4” Country of origin: China; Projectile dimension: 642 mm; Round weight: 21.36 kg; Projectile weight (without Sabot): 4.1kg
The aluminum sabot allows for a lighter projectile and hence a higher initial velocity. [ 6 ] The baseline design contains a propulsion system consisting of a metal case base, a combustible cartridge case, case adapter, nineteen perforated hexagonal JA2 propellant, a propellant containment device (cloth bag), and an M129 primer (all are ...
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 SLAP design incorporates a polymer sabot, which allows for the use of a tungsten penetrator projectile of a lesser diameter than the original bore.By using the casing of a large cartridge with a lightweight projectile, the velocity of the projectile is greatly increased and the sectional density is improved without requiring a (potentially dangerous) increase in chamber pressure.
