The exploding-bridgewire detonator (EBW, also known as exploding wire detonator) is a type of detonator used to initiate the detonation reaction in explosive materials, similar to a blasting cap because it is fired using an electric current. EBWs use a different physical mechanism than blasting caps, using more electricity delivered much more ...
Types of detonators include non-electric and electric. Non-electric detonators are typically stab or pyrotechnic while electric are typically "hot wire" (low voltage), exploding bridge wire (high voltage) or explosive foil (very high voltage). [2] [3] The original electric detonators invented in 1875 independently by Julius Smith and Perry ...
(A) Slapper detonator's pellet or flyer impacts a wider area of surface on the explosive output charge, and even though energy is lost to the sides of the area impacted, a cone of explosive is efficiently compressed. (B) EBW detonators only initiate a single point, and energy is lost in all directions, making the energy transfer less efficient.
It is the central multi-purpose component of a modular system of detonating cords, pyrotechnics and various other explosive charges with many different uses. [1] The ignition charge of the device is a blend of zirconium, potassium perchlorate, Viton B and graphite, often abbreviated as ZPP. [2] Uses of the device include:
A Virginia man was arrested last month after investigators found what the Federal Bureau of Investigation described as the largest seizure of explosive devices in the agency's history, prosecutors ...
This is a list of colleges and universities in the U.S. state of Virginia. The oldest college or university in Virginia is The College of William and Mary, founded in 1693. In 2010, the Virginia Tech Carilion School of Medicine became the newest. The largest institution is Liberty University, with over 143,000 students. [1]
A typical device consists of a solid cylinder of explosive with a metal-lined conical hollow in one end and a central detonator, array of detonators, or detonation wave guide at the other end. Explosive energy is released directly away from ( normal to ) the surface of an explosive, so shaping the explosive will concentrate the explosive energy ...
