A detonator is a device used to make an explosive or explosive device explode. [1] Detonators come in a variety of types, depending on how they are initiated (chemically, mechanically, or electrically) and details of their inner working, which often involve several stages. Types of detonators include non-electric and electric.
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 ...
A naval mine is a self-contained explosive weapon placed in water to damage or destroy surface ships or submarines. Similar to anti-personnel and other land mines , and unlike purpose launched naval depth charges , they are deposited and left to wait until, depending on their fuzing , they are triggered by the approach of or contact with any ...
Detonation can be initiated only by a shockwave, such as when a detonator inserted into it is fired. [8] When detonated, C-4 rapidly decomposes to release nitrogen, water and carbon oxides as well as other gases. [8] The detonation proceeds at an explosive velocity of 8,092 m/s (26,550 ft/s). [14]
A bouncing bomb is a bomb designed to bounce to a target across water in a calculated manner to avoid obstacles such as torpedo nets, and to allow both the bomb's speed on arrival at the target and the timing of its detonation to be predetermined, in a similar fashion to a regular naval depth charge.
It is normally deployed in water one or two meters deep, and has a central fixing point for a tilt rod. Two men can lay a single mine in 10 to 20 minutes. The mine uses a VPDM-1M tilt rod fuse with an MD-10 detonator.
They used an early form of chemical detonator. During the American Civil War, the term torpedo was used for what is today called a contact mine, floating on or below the water surface using an air-filled demijohn or similar flotation device. These devices were very primitive and apt to prematurely explode.
This is a typical "default" rating for connecting charges for blasting; lighter detonating cords may be used for "low noise blasting" and movie special effects, while heavier cords, used where the cord is employed to have some direct explosive effect—such as for precision rock carving work—may use 50 to 250 grain/foot (10 to 50 g/m ...
