Shells bursting charge

The higher specific gravity of 75/25 Octol can make the bursting charge of a shell containing it appreciably heavier than that of the same shell... 

The fragmentation shell has thicker walls than the demolition shell. The HE bursting charge is larger for the demolition than for the fragmentation shell... 

Ammonium Picrate (AmmPicr), Dunnite or Explosive D, was standardized in the US as a bursting charge for AP (Armor-Piercing) shells (Ref 64, p 2-3). Its prepn and properties are described in Ref 70, pp 136—39, where it is stated that AmmPicr was first prepd in 1841 by Marchand and in 1869 used by Brugbre in admixture with K nitrate as a proplnt. Used as an HE after 1900 (See also 1841)... 

WWII. Ethylenedinitramine, EDNA or Haleite, first prepd in 1887 by Franchimont Klobbie and developed in 1935 as a military explosive by G.C. Hale, was standardized during WWII as a component of EDNATOL (EDNA+TNT) serving as bursting charge for bombs and shells (Ref 70, pp 131-R and 154). See also Vol 6 of Encycl, pp E238ff... 

Horse Detonator. The name given to the American M46 fuze because it can initiate much more effectively than standard fuzes, such as the Mark III. The M46 fuze can be used even with the worst exuding shell, where the standard fuzes nearly always fail. It compensates for both desensitized boosters and bursting charges. In all cases, it gives high-order detonations... 

Ditto in 1/8 Al—50% expls and 50% unaffected Sand Test-See Brisance by Sand Test Sensitivity to Impact—See Impact Sensitivity Sensitivity to Initiation—See Initiation, Sensitivity to Stability Test—See Vacuum Stability Test Vacuum Stability Test at 120°—0.37cc of gas evolved in 40 hrs from 1 g sample Velocity of Detonation—See Detonation Rate Viscosity, Efflux-24.8 Saybolt Seconds Method of manuf of HTA—3 is similar to that used for Torpex, namely purified TNT is melted by heating it to ca 100° in a steam-jacketed kettle, equipped with a stirrer. Water wet HMX is added slowly to molten TNT, while continuing to stir it and to heat, until all the water is evapd. Aluminum powder is added and the mixture continued to be stirred until uniform and then cooled, with stirring, to obtain a slurry suitable for pouring into shells or bombs to serve as their bursting charges Refs 1) G. Silvestro H. Will III, PA Instrumentation Rept 1232—58 (1958) (Suitability of HTA-3 as HE) 2) Anon, AMCP 706-177 (1967), pp 178-81 362 (Torpex) (1971), pp 178-81... 

Hudson Explosive. Explosive mixture intended for use as a bursting charge in shells and prepd in the USA in 1889 by mixing NG with NC, previously dissolved in acetone, ethyl acetate or ether-alcohol mixture Ref Daniel (1902) 378... 

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... 

The Germans developed a 15cm shell, for use against ground targets, which contained 12 or more celluloid cylinders surrounded by yellow phosphorous imbedded in paraffin. A central tube of Black Powder was used as a bursting charge... 

Japanese 120mm Incendiary Projectile contained 48 steel pellets embedded in a canister filled with white phosphorous. Each pellet had an annular cavity to increase the amount of phosphorous that could be retained by each pellet. The shell was exploded by means of a bursting charge of HE, fired by a point-detonating fuse... 

In the book of Belgrano (Ref 31, pp 355—60) are described chlorate and perchlorate Cheddites Accdg to Ref 28, p 321, Cheddites are too sensitive to mechanical action to be used as bursting charges in shells, but they can be used for loading land mines (See also Cremonite, Esplosivo 86/14, Esplosivo P, Esplosivo S, Manlianite, Polvere cannel and Romite)... 

Accdg to Molina (Ref 1, p 358), the following Piombite was used during WW1 as a bursting charge in cast-iron shells of medium caliber Pb nitrate 75, Ca silicide 16, Pb carbonate (basic)... 

Granular TNT is used as the bursting chge of hand grenades, mortar shells and in mines. Cast TNT is used as a bursting charge in some bombs,... 

The following expl compns, contg RDX, Angayaku, Chauyaku, Haishokuyaku, Koshitsu, Nigotanoyaku-Mk 2, Tanoyaku, Type 94M Explosive and Unknown Name Explosives were used as Bursting Charges of Bombs and Shells (Ref 5, p 373)... 

F.G. Powder. Fine grain Black Powder used in die 19th century in England as proplnt for smaller caliber cannons and as a bursting charge for shrapnel shells Ref Daniel (1902), p 300...
