An early mention of "hydrostatic shock" appeared in Popular Mechanics in April 1942. [7] In the scientific literature, the first discussion of pressure waves created when a bullet hits a living target is presented by E. Harvey Newton and his research group at Princeton University in 1947: [8]
As it has been understood that propellant burns more efficiently in shorter, wider-diameter casings, [7] modern ammunition has changed over time to become shorter and wider than previous cartridges. The .30 TC (0.308 in (7.8 mm) x 1.920 in (48.8 mm) is a non-magnum that is somewhat shorter and wider than the .308 and .30-06. [ 1 ]
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.
Destroyed T-72B3 in Ukraine with the turret separated. The jack-in-the-box effect is known to occur in tanks which are "buttoned up" (i.e. with all hatches closed and locked), and which have internally stored ammunition and no blowout panels on the ammunition storage area.
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 ...
This fragmentation by blast wave is known as 'scabbing' or 'spalling', with the fragments termed 'scabs or 'spall'. [4] [2]Depending upon the armour thickness, a heavy piece of target material (4 to 10 kg (8.8 to 22.0 lb) for a 120 mm (4.7 in) round used in Arjun MBT [4]) can separate out from the other end of the target with supersonic velocities.
The Thompson/Center Ugalde, or TCU family of wildcat cartridges, was developed by Wes Ugalde of Fallon, Nevada, by necking up .223 Remington brass to accept larger bullets. The cartridges were developed for the Thompson Center Arms Contender single shot pistol, and are widely used in handgun metallic silhouette competition and handgun hunting.
