Pyrotechnic Bomb Fuzes

Nonsmokeless Powder. Composition is not given. Used by the Army as a Main Charge in 20-mm Machine Gun Ammo, as an ejector chge in 70-mm Mortar Shells, Shrapnel Shells Pyrotechnics in Delays, Relays Igniters for Bomb Projectile Fuzes and as a Substitute Charge for some Bombs, Grenades and Projectiles (Ref 1, p 27 Ref 5, p 366)...

C) Bombs, Pyrotechnic. They contain pyrotechnic naterials and are classified as bombs because of heir similarity to bombs in body, fuzing and nethod of suspension. These bombs may be sub-livided into ... 

It was concluded, at that time, that replacement of Al by B in military expls showed no advantages over std expls. Boron has been used in the development of some gasless delay fuze compns and in pyrotechnic mixts for flares incendiary bombs (Ref 3). Werbel(Ref 2a) proposed Ba chromate/boron 95/5 mixt as delay compn 90/10 mixt as an igniter. Taschler Jones(Ref 5) have detd the e-lectrostatic sensitivity of barium chromate/boron compns. The performance of boron expls is described by Mader(Ref 4)... 

III) Detonation or Explosion., It can be conducted either by initiating the expls contained in ammo, or by the force of detonation of other expl material s placed in contact with the item. Ammo items which can be destroyed by these methods include artillery shells, aerial bombs, mortar shells, shrapnel shells, photoflash bombs, antitank mines, rockets, grenades (hand and rifle), loaded metal components (such as fuzes, primers, detonators, boosters bursters) and pyrotechnic...

Fuzes, a term often used synonymously with fuse, are devices which initiate high explosives (detonating fuze) or low explosives (igniting fuze) in projectile ammunition or pyrotechnics after launch, or which activate the main charge of a mine, bomb, or other nonprojectile ammunition. In addition to an explosive, fuzes incorporate some kind of mechanical or electronic initiation device ... 

Fuse A train of pyrotechnic composition (usually black powder), often covered with twine, thread, or twisted paper, as well as waterproofing material. Fuses are lit by a safety match or other hot object, and provide a time delay to permit the person igniting the device to retreat to a safe distance. This term should not be confused with fuze, which is a device used to initiate a military explosive device such as a bomb.
