Black powder ignition charge

A typical device for the determination of the flash detonator sensitivity to the flame of the black powder ignition charge is presented in Figure 2.34. 

Uses In priming compositions for igniting charges of smokeless powder (small arms) for igniting the black powder in primers of artillery ammunition, and for igniting the black-powder igniters in separate-loading ammunition. 

Squib A device containing an electric match and a small quantity of black powder output charge. The electric match ignites the black powder, which in turn produces a flame and sparks to ignite the propellant or other pyrotechnic composition. 

Compositions with high ignition temperatures (i.e., above 600°C) can be difficult to ignite using solely the "spit" from a black powder fuse or similar mild ignition stimulus. In such situations, an initial charge of a more-readily-ignitible material, called a "first fire," is frequently used. The requirements for such a mixture include [ 3] ... 

To the definition given under item (a), may be added that propellant igniters consist of a charge of quick-burning BkPdr (See BLACK POWDER in Ref 44, p B171), which can be either in the form of a compressed disc attached to a "simple"primer or in the form of small grains contained in a perforated tube. In a 3rd method, loose BkPdr is contained in a Small cloth bag which is placed, during... 

Sometimes, in addition to the igniter bag, a charge of Black Powder running through the propellant in the form of a core is also used Refs 1) Hayes (1938), pp 34-35 2) Ohart (1946), pp 184 189 3) Also see Sect 3, Part D of Vol 4, pp D795-97... 

For instance, for igniting propellant charges of smokeless powder, grained Black Powder is used, which in turn is ignited by means of a primary ignition composition... 

The primary igniting mixture in the Ml9 electric igniter (used for simulating gunflash) contains dinitrodiazophenol 40 3, potassium chlorate 58 3 and nitrostarch 2 0.5%. This mixture is ignited by heat produced by incandescent resistance wire and in turn ignites the charge of Black Powder placed next to it... 

With the introduction (about the end of the 15th century) of hollow type projectiles charged with Black Powder, these shells also became, to a certain extent, incendiary missiles. This was due to the fact that, when such a shell burst, the flame produced by the explosion of the Black Powder could ignite any closely-located inflammable object... 

In TM 9-1985-6 (1953), listed here as Ref 16 are described and illustrated under Cartridge Cases, without including Italian names, the cases for several weapons. Their igniter charges range from 10 to 5 Og of Black Powder... 

On releasing the flare, the pyrotechnic delay (inside the fuze) was ignited. This fired the quickmatch, which in turn burned thru the flash tube and ignited the Black Powder charge in the tail. The pressure of the gases... 

A device, described in Refs 2, p 422 and 4 p 623 as the electric fuze, ERZ 39, was used for igniting the black powder charge which.sec off the propellant of 15 cm and 21 cm rockets. This device is briefly described in this work under Rocket Propellant Igniter...
