In an explosive, pyrotechnic device, or military munition, a fuse (or fuze) is the part of the device that initiates function. In common usage, the word fuse is used indiscriminately. In common usage, the word fuse is used indiscriminately.
Fuse: Cord or tube for the transmission of flame or explosion usually consisting of cord or rope with gunpowder or high explosive spun into it. (The spelling fuze may also be met for this term, but fuse is the preferred spelling in this context.) [7] Fuze: A device with explosive
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.
An artillery fuze or fuse is the type of munition fuze used with artillery munitions, typically projectiles fired by guns (field, anti-aircraft, coast and naval), howitzers and mortars. A fuze is a device that initiates an explosive function in a munition, most commonly causing it to detonate or release its contents, when its activation ...
Proximity fuse MK53 removed from shell, circa 1950s. A proximity fuse (also VT fuse [1] [2] [3] or "variable time fuze") is a fuse that detonates an explosive device automatically when it approaches within a certain distance of its target. Proximity fuses are designed for elusive military targets such as aircraft and missiles, as well as ships ...
It is a high-speed fuse which explodes, rather than burns, and is suitable for detonating high explosives. The detonation velocity is sufficient to use it for synchronizing multiple charges to detonate almost simultaneously even if the charges are placed at different distances from the point of initiation. It is used to reliably and ...
However "this fuse soon replaced the less reliable fuses which were made of straws or quills filled with black powder, thus greatly reducing the hazard of accidental explosions in mining or construction." [8] Word of the reliability of Bickford's safety fuse spread, and was soon in large demand across world markets. [9]
C-4 or Composition C-4 is a common variety of the plastic explosive family known as Composition C, which uses RDX as its explosive agent. C-4 is composed of explosives, plastic binder, plasticizer to make it malleable, and usually a marker or odorizing taggant chemical.
