WebBridgewire. A bridgewire or bridge wire, also known as a hot bridge wire ( HBW ), is a relatively thin resistance wire used to set off a pyrotechnic composition serving as pyrotechnic initiator. By passing of electric current it is heated to a high temperature that starts the exothermic chemical reaction of the attached composition.

WebMIL-STD-1316D the basic SA safety guide requires in-line detonators to be qualified in accordance with MIL-I-23659, yet 23659 was based primarily on qualifying hot bridge wire devices and is poor to qualify the in-line detonator of choice the EXploding Foil Initiator (EFI). The report proposes changes to 23659 to qualify EFI's and EBW's. WebAn introduction to exploding bridge-wire (EBW) detonators is given followed by an extensive critical review of open source literature pertaining to these devices.

WebIn the course of a failure investigation, corrosion of the lands was occasionally found in developmental lots of semiconductor bridge (SCB) detonators and igniters. Evidence was found in both detonators and igniters of the gold layer being deposited on top of a corroded aluminum layer, but inspection of additional dies from the same wafer did not reveal any … WebJul 1, 2024 · Even though the exploding bridge wire (EBW) detonator has been in use for over 60 years, there are still discussions about the mechanism for achieving detonation. … 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, … See more 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 … See more The bridgewire is usually made of gold, but platinum or gold/platinum alloys can also be used. The most common commercial wire size is 0.038 mm (1.5 mils) in diameter and 1 mm (40 mils) … See more • Nuclear weapon design - Implosion-type weapon • Triggering sequence See more EBWs were developed as a means of detonating multiple explosive charges simultaneously, mainly for use in plutonium-based nuclear weapons in which a plutonium core … See more The EBW and the slapper detonator are the safest known types of detonators, as only a very high-current fast-rise pulse can successfully trigger … See more • Elements of Fission Weapon Design, section 4.1.6.2.2.6 See more seller admin center shopee
