The Department of Defense Identification Code (DODIC) is a 4-symbol alphanumeric code designation for a type of item. It starts with 1 or 2 code letters and the remainder is a 2- or 3-digit code number. It indicates an item of supply (e.g., 5.56mm NATO M193 Ball) and its packing sub-unit (e.g., 20-round carton, 10-round clip, or 200-round ...
An air burst or airburst is the detonation of an explosive device such as an anti-personnel artillery shell or a nuclear weapon in the air instead of on contact with the ground or target. The principal military advantage of an air burst over a ground burst is that the energy from the explosion, including any shell fragments , is distributed ...
TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion.The ton of TNT is a unit of energy defined by convention to be 4.184 gigajoules (1 gigacalorie), [1] which is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of TNT.
1.2 — Explosives with a blast/projection hazard. 1.3 — Explosives with a minor blast hazard. (rocket propellant, display fireworks) 1.4 — Explosives with a major fire hazard. (consumer fireworks, ammunition) 1.5 — Blasting agents. 1.6 — Extremely insensitive explosives.
Airburst effect from 40mm round on dummy soldiers. An airburst round is a type of tactical anti-personnel and anti-aircraft explosive ammunition, typically a shell or grenade, that detonates in midair, causing air burst effect fragment damage to enemy personnel or aircraft (notably comparably unsophisticated unmanned aircraft systems such as modified racing drones).
a small amount of a more powerful secondary explosive, directly in contact with the primary, and called "base" or "output" explosive, able to carry out the detonation through the casing of the detonator to the main explosive device to activate it. Explosives commonly used as primary in detonators include lead azide, lead styphnate, tetryl, and ...
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.
The velocity of detonation is an important indicator for overall energy and power of detonation, and in particular for the brisance or shattering effect of an explosive which is due to the detonation pressure. The pressure can be calculated using Chapman-Jouguet theory from the velocity and density.
