What is discarding sabot?
Discarding of sabot Gas pressure is used to delay the unlocking of the pins holding the rear part of the sub-projectile by gyroscopic forces. This, in combination with the sub-projectiles’ higher sectional density, gives the resulting sub-projectile vastly reduced aerodynamic drag in comparison to the APCR.
How do armor-piercing shells work?
Rifle armor-piercing ammunition generally carries its hardened penetrator within a copper or cupronickel jacket, similar to the jacket which would surround lead in a conventional projectile. Upon impact on a hard target, the copper case is destroyed, but the penetrator continues its motion and penetrates the target.
When was armor-piercing discarding sabot invented?
1944
use in artillery In 1944 Britain perfected “discarding-sabot” projectiles, in which a tungsten core was supported in a conventional gun by a light metal sabot that split and fell free after leaving the muzzle, allowing the core to fly on at extremely high velocity.
Does Apfsds bounce?
APFSDS don’t bounce off because they are built in such a way that they deliver that energy even at extreme angles. It’ll shatter before it’ll ever bounce off the armor.
What does Army sabot mean?
A sabot (UK: /sæˈboʊ, ˈsæboʊ/, US: /ˈseɪboʊ/) 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.
What is a Frangible Armour Piercing Discarding Sabot?
Many newer medium calibre APDS cores use a frangible high density alloy, the resulting projectiles are called Frangible Armour Piercing Discarding Sabot ( FAPDS) for APDS types, or FRAP (Frangible Armour Piercing) for full-calibre projectiles. During penetration, a frangible projectile’s core fragments into many high-velocity pieces.
Why is the outer sheath called a sabot?
To overcome these limitations the British devised a way for the outer sheath to be discarded after leaving the bore. The name given to the discarded outer sheath was the sabot (a French word for a wooden shoe ). For APDS projectiles the sabot is also known as a pot, as the sabot resembles a flower pot in shape.
How effective is a sabot on a pistol?
While the sabot improved short range effectiveness, the additional drag caused the performance of the shot to fall off dramatically with increasing range.
What happens when a frangible projectile penetrates?
During penetration, a frangible projectile’s core fragments into many high-velocity pieces. The effect of a frangible projectile on a lightly armoured target is much the same as a high explosive incendiary round, but with a cloud of dense, high-velocity fragments penetrating deeper into the target’s interior.
