Artillery Time fuzes detonate after a set period of time. Early time fuzes were igniferous (i.e. combustible) using a powder train. Clockwork mechanisms appeared at the beginning of the 20th century and electronic time fuzes appeared in the 1980s, soon after digital watches. Almost all artillery time fuzes are fitted to the nose of the shell.
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 at sea and ground forces.
Early artillery time fuzes were nothing more than a hole filled with gunpowder leading from the surface to the centre of the projectile. The flame from the burning of the gunpowder propellant ignited this "fuze" on firing, and burned through to the centre during flight, then igniting or exploding whatever the projectile may have been filled with.
This safety feature is expected to give soldiers more confidence when calling in artillery support close to their position. [7] [8] The PGK fuze weighs 3 lb (1.4 kg), 1 lb (0.45 kg) more than a standard fuze because of the addition of fins and an alternator. The self-contained system does not need a battery since the alternator inside generates ...
R2ZEG = 155mm HE M102 with M54 Time & Super-Quick Fuze with white bag charge. R2ZEW = 155mm Casualty Gas ( H ) M105 with M51A1 Point Detonating Fuze with green bag charge. Sub-group R3 (service fuzes and primers for pack, light, and medium field artillery)
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.
These graze and impact fuzes continued to be used as intended for medium and heavy artillery high-explosive shells. Up to and including the Battle of the Somme in 1916, British forces relied on shrapnel shells fired by 18-pounder field guns and spherical high-explosive bombs fired by 2-inch "plum-pudding" mortars for cutting barbed-wire defences.
The plug is removed and replaced with a fuze for firing. The complete projectile weighs 43.2 kg (95 lb), is 800 mm (31 in) long and contains 15.8% explosive by weight. It is a separate-loading projectile—propellant bags or modular artillery charge system (MACS) charges are loaded separately.
