IEC 61000-4-4 is the International Electrotechnical Commission's immunity standard based on electrical fast transient (EFT) / burst transients. This publication is part of the greater IEC 61000 group of standards which is covered under IEC TR 61000-4-1:2016. [1] The current third version of this standard (2012) replaces the second version (2004 ...
On the other end a transformer enables the generator to work more efficiently into the electrical load. An explosively pumped flux compression generator (EPFCG) is a device used to generate a high-power electromagnetic pulse by compressing magnetic flux using high explosives. EPFCGs are physically destroyed during operation, making them single-use.
Powder-actuated tools are powered by small explosive cartridges, which are triggered when a firing pin strikes a primer, a sensitive explosive charge in the base of the cartridge. The primer ignites the main charge of powder, which burns rapidly.
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 ...
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 ...
An explosive device is a device that relies on the exothermic reaction of an explosive material to provide a violent release of energy. [1] Applications of explosive devices include: Building implosion ; Excavation; Explosive forming; Explosive welding; Mining of minerals; Murder. Assassination; Riot control; Terrorism; War; Types of explosive ...
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.
The EBW was invented by Luis Alvarez and Lawrence Johnston for the Fat Man–type bombs of the Manhattan Project, during their work in Los Alamos National Laboratory.The Fat Man Model 1773 EBW detonators used an unusual, high reliability detonator system with two EBW "horns" attached to a single booster charge, which then fired each of the 32 explosive lens units.
