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 ASM-A-1 Tarzon, also known as VB-13, was a guided bomb developed by the United States Army Air Forces during the late 1940s. Mating the guidance system of the earlier Razon radio-controlled weapon with a British Tallboy 12,000-pound (5,400 kg) bomb, the ASM-A-1 saw brief operational service in the Korean War before being withdrawn from service in 1951.
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]
Rope trick effects visible from one of Operation Tumbler–Snapper's tower-mounted test shots in 1952, taken with a rapatronic camera. The adjacent photograph shows two unusual phenomena: bright spikes projecting from the bottom of the fireball, and the peculiar mottling of the expanding fireball surface.
Stabo. Fuzes for air-dropped bombs have generally used an internally mounted inertia fuze, triggered by the sudden deceleration on impact. Owing to the risk of an aircraft crash, or even the need to land with an undropped bomb still on board, these are protected by sophisticated safety systems so that the fuze can only be triggered after it has been dropped intentionally.
They are not reported as mines; however, the emplacing unit must ensure that the mines are removed, detonated, or turned over to a relieving unit. The 100-foot (30 m) M4 electric firing wire on a green plastic spool is provided in each bandolier. The M57 firing device (colloquially referred to as the "clacker") is included with each mine.
Of the scene which has been left after the removal, Mrs James added: “It looks horrendous with all the work they had to do to get rid of the bomb. “They knocked down a wall and the garden is ...
The bomb was adapted from a British plastic explosive, which had been seized by the Abwehr from captured SOE agents. The pencil detonator consisted of a thin copper tube containing copper chloride that would take about ten minutes to silently eat through wire holding back the spring-loaded firing pin from the percussion cap .
