The ammunition may also be called semi-armor-piercing high-explosive incendiary (SAPHEI). [1] Typical of a modern HEIAP shell is the Raufoss Mk 211 [2] designed for weapons such as heavy machine guns and anti-materiel rifles. The primary purpose of these munitions is armor penetration with better beyond-armor effects. [3]
After workers loaded the weapons onto a conveyor, automated equipment would take over the process. The equipment removed the explosive component of the weapon and drained the chemical agent. The explosive and chemical agent were then incinerated at high temperature. [9] The metal weapons casings were then thermally decontaminated and scrapped ...
Direct impingement operation increases the amount of heat that is deposited in the receiver while firing, which can burn off and cover up lubricants. The bolt, extractor, ejector, pins, and springs are also heated by the same high-temperature gas. These combined factors reduce service life of these parts, reliability, and mean time between ...
The intermediate flash is caused by shock waves created by the high speeds of the escaping gases and projectile, and appears as a reddish disc-shape in front of the muzzle. The secondary flash appears farthest from the muzzle as a large white or yellow fireball , and is caused by a newly ignited oxidation of incompletely combusted ejecta when ...
It takes very high temperatures to ignite, but when alight, it can burn through solid steel. In World War II, such devices were employed in incendiary grenades to burn through heavy armour plate, or as a quick welding mechanism to destroy artillery and other complex machined weapons.
High-explosive anti-tank (HEAT) is the effect of a shaped charge explosive that uses the Munroe effect to penetrate heavy armor. The warhead functions by having an explosive charge collapse a metal liner inside the warhead into a high-velocity shaped charge jet; this is capable of penetrating armor steel to a depth of seven or more times the ...
MIL-STD-810 is maintained by a Tri-Service partnership that includes the United States Air Force, Army, and Navy. [2] The U.S. Army Test and Evaluation Command, or ATEC, serves as Lead Standardization Activity / Preparing Activity, and is chartered under the Defense Standardization Program (DSP) with maintaining the functional expertise and serving as the DoD-wide technical focal point for the ...
C-4 or Composition C-4 is a common variety of the plastic explosive family known as Composition C, which uses RDX as its explosive agent. C-4 is composed of explosives, plastic binder, plasticizer to make it malleable, and usually a marker or odorizing taggant chemical.
