Insensitive munitions are munitions that are designed to withstand stimuli representative of severe but credible accidents. The current range of stimuli are shock (from bullets, fragments and shaped charge jets), heat (from fires or adjacent thermal events) and adjacent detonating munitions.
An example of a low-explosive train is a rifle cartridge, which consists of a primer consisting of a small amount of primary high explosive which initiates the explosive train; an igniter which is initiated by the primer and creates a flame that ignites the propellant
In explosives engineering, sensitivity refers to the degree to which an explosive can be initiated by impact, heat, or friction. [1] Current in-use standard methods of mechanical (impact and friction) sensitivity determination differ by the sample preparation (constant mass or volume is usually used; pile or pressed pellet), sample arrangement (confined/unconfined sample etc), instrument type ...
For example, a large bomb casing was filled with small sticks of incendiary ; the casing was designed to open at altitude, scattering the bomblets in order to cover a wide area. An explosive charge would then ignite the incendiary material, often starting a raging fire.
The term bomb is not usually applied to explosive devices used for civilian purposes such as construction or mining, although the people using the devices may sometimes refer to them as a "bomb". The military use of the term "bomb", or more specifically aerial bomb action, typically refers to airdropped, unpowered explosive weapons most ...
During the Attack of Pearl Harbor, the USS Arizona was struck with an armor-piercing bomb which penetrated the upper deck and stopped inside the forward magazine. The bomb triggered an explosion which was powerful enough to cut the Arizona in half and is considered a sympathetic detonation as there was an apparent delay between the detonation of the bomb and the contents of the forward magazine.
An example is the British World War II Fuze, Percussion, D.A., No. 233 [2] ('direct action') The primary explosive transmits its detonation to an explosive booster within the fuze, then in turn to the main charge of the shell. As an artillery shell lands with a considerable impact, the "soft" nose may be made robust enough to be adequately safe ...
There are two types of taggant which have been considered for use with explosives. One is to help detect the presence of a bomb in, for example, airport screening of luggage; and the other to assist the police in identifying the explosive after the detonation of such a bomb.
