The exploding wire method or EWM is a way to generate plasma that consists of sending a strong enough pulse of electric current through a thin wire of some electrically conductive material. The resistive heating vaporizes the wire, and an electric arc through that vapor creates an explosive shockwave .
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 ...
The two wires came close but did not touch, so a large electric spark discharge between the two wires would fire the cap. [ 6 ] In 1832, a hot wire detonator was produced by American chemist Robert Hare , although attempts along similar lines had earlier been attempted by the Italians Volta and Cavallo. [ 7 ]
Instead of directly coupling the shock wave from the exploding wire (as the bridgewire does), the expanding plasma from an explosion of a metal foil drives another thin plastic or metal foil called a "flyer" or a "slapper" across a gap, and its high-velocity impact on an explosive (for example, PETN or hexanitrostilbene) then delivers the ...
A detonator is a device used to trigger an explosive.
UMass said it would pay a student the $10,000 prize for a halftime promotion at a women’s basketball game after a dispute with an insurance company over whether he stepped over the line when he made a half-court shot.
With the PETN exploding at a rate of approximately 6,400 m/s (21,000 ft/s), any common length of detonation cord appears to explode instantaneously. It is a high-speed fuse which explodes, rather than burns , and is suitable for detonating high explosives .
In 2001, an 18-year-old committed to a Texas boot camp operated by one of Slattery’s previous companies, Correctional Services Corp., came down with pneumonia and pleaded to see a doctor as he struggled to breathe.
