The "rope tricks" that protrude from the bottom of the fireball are caused by the heating, rapid vaporization and then expansion of guy wires that extend from the shot cab—the housing at the top of the bomb tower that contains the explosive device—to the ground.
Graphite bomb BLU-114/B. A graphite bomb is intended to be a non-lethal weapon used to disable an electrical grid.The bomb works by spreading a dense cloud of extremely fine, chemically treated carbon filaments over air-insulated high voltage installations like transformers and power lines, causing short-circuits and subsequent disruption of the electricity supply in an area, a region or even ...
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]
However, they require a bulky power source for the current surges required. The extremely short rise times are usually achieved by discharging a low-inductance, high-capacitance, high-voltage capacitor (e.g., oil-filled, Mylar-foil, or ceramic) through a suitable switch (spark gap, thyratron, krytron, etc.) into the bridge
The German Stachelbombe (nose-spike bomb) or stabo of WWII was a standard bomb, from 50 kg to 500 kg, modified for use from low altitude. [5] To avoid the risk of ricochet from the ground, a nose spike was fitted to penetrate first and anchor the bomb against bouncing — without this, there was a risk of the dropping aircraft not only missing ...
However, half their weight was due to the cast high tensile steel casing necessary for penetrating the ground – up to 130 ft (40 m) – before exploding. The MOAB, in contrast, has a light 2,900 lb (1,300 kg) aluminum casing surrounding 18,700 lb (8,500 kg) of explosive Composition H-6 material.
At least two people have died and hundreds of thousands are without power as a second powerful bomb cyclone approaches the Pacific Northwest and Northern California, causing high winds, heavy rain ...
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 .
