A blast injury is a complex type of physical trauma resulting from direct or indirect exposure to an explosion. [1] Blast injuries occur with the detonation of high-order explosives as well as the deflagration of low order explosives. These injuries are compounded when the explosion occurs in a confined space.
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 ...
The risk of lung trauma is very high, as is the danger from any unsecured objects that can become projectiles because of the explosive force, which may be likened to a bomb detonation. Immediately after an explosive decompression, a heavy fog may fill the aircraft cabin as the air cools, raising the relative humidity and causing sudden ...
The human body can survive relatively high blast overpressure without experiencing barotrauma. A 5 psi blast overpressure will rupture eardrums in about 1% of subjects, and a 45 psi overpressure will cause eardrum rupture in about 99% of all subjects. The threshold for lung damage occurs at about 15 psi blast overpressure.
The Javelin missile's tandem warhead is a high-explosive anti-tank (HEAT) type. [11] This round utilizes an explosive shaped charge to create a stream of superplastically deformed metal, formed from trumpet-shaped metallic liners. The result is a narrow high velocity particle stream that can penetrate armor.
The high-explosive anti-tank (HEAT) rocket of the RL-83 Blindicide can penetrate 300 millimeters of rolled homogeneous armour or one meter of concrete. [2] Besides HEAT, the Blindicide can also fire anti-personnel, smoke, incendiary and illumination rounds. The Blindicide was also produced in a 100 mm version (the RL-100).
Children are less likely to survive AR-15 wounds. The leading cause of death in children between the ages of 1 and 19 in the U.S. is gun violence, according to a recent New England Journal of ...
