Baron von Lenk, representing Austria, was happy that Prussia did not obtain the patent of Schonbein Bottger dealt directly with them to obtn the method. He started to work on improvement of stability and possibility of adopting the improved powder as cannon propellant (Ref 44, p 242)... [Pg.137]

Accdg to Gorst (Ref 71, p 7), rifled weapons started to be used in Russia Note British and French troops had such weapons already during Crimean War 1860 and After. Cannon Propellants. Up to about 1860 s Black Powder was used exclusively as cannon and rifle propellant. Then attempts were made to replace it with smokeless propints made from incompletely colloided Nitrocellulose. These proplnts were too, fast burning (See... [Pg.138]

The Germans used anti-flash charges containing potassium chloride in their cannon propellants. The charges, in bags of artificial silk or cotton cloth, were loaded between the base of the projectile and the propellant. Obviously, all the additions described above increased the smoke formed when the rounds were fired. [Pg.664]

DOUBLE-BASE AND TRIPLE-BASE PROPELLANTS. A description of double-base proplnts containing NC + NG was given in this Encycl under BALLI5TITE (Vol 2, pp B8-L to B10-L), under CANNON PROPELLANT Vol 2, pp C33-L to C37-L) and under CORDITE (VoL 3, PP C531-L to C541-R). Some Ball Powders, described in Vol 2, pp Bll-R to B16-L can be made double-base. The description did not include the German proplnts which were described previously in Refs 1, 2 3 and in Ref 4, pp Get 142 (Table 43) Ger 146 (Table 46), under PROPELLANT (Treibmittei)... [Pg.430]

A brief description of these proplnts known as Triple-Base Cannon Propellants is given in Vol 2 of Encycl, p C37-R, while compns of proplnts M15, M17, T20, T29, T34 and T39 are given in Table V on p C34... [Pg.759]

Amide Powder (Amidpulver, in Get). One of the earliest types of Ger smokeless artillery propellants. The original compn patented in 1885 by Gans contained AN 35"38, K nitrate 40-46 charcoal 14-22%. Its formulation was modified several times until a powder which was flashless and nearly smokeless was obtained. The improved compn AN 37, FC nitrate 14 charcoal 49% was used during WWI as a cannon propellant. Amide powder left only a small residue on combustion. This was attributed to the formation and ignition of potassamide which is formed on burning the powder... [Pg.168]

NC(13.15% N) 87, DNT 10 DBuPh 3%. At about the same time, the proplnt called FNH (Flashless-Nonhygroscopic) was developed. Its compn was NC(12.6% N) 74, NC(13.25% N ), 20, DNT 5 DPhA 1%. Designations NH and FNH are not used any more, being replaced by letters M or T followed by numbers 1,2,3 etc(See Tables V,VI VII). M means a proplnt adopted for service and T, one in the experimental stage Current US Single-Base Cannon Propellants. In Table V there are listed only three proplnts (MIAI, M3D M31) which are based on "Pyrocellulose (NC with 12.6%N), because the majority of proplnts are now based on "Blend (NC 13.15-13.25%N), which is prepd by mixing "Pyro (12.6%N) with Guncotton (13.4-13.45%N). The 1st component is sol in 2 l-eth-alc, while the 2nd is not. Cannon proplnts Ml, M6, Ml4 and recoilless gun proplnt M10 are based on NC with 13.25%N and so are small arms proplnts IMR (Improved Military Rifle) and M12 (listed here for comparison with cannon proplnts)...

Properties of Double-Base Cannon Propellants. Double-base NC-NG proplnts are considered "hot proplnts, because their heats of expl and flame temps are much higher than those of single-base proplnts (See Tables V, VI VII). This means that... [Pg.428]

US Double—Base Cannon Propellants. In Tables V, VI VII are given compns and some props of presently used proplnts. Proplnts M2, M5, M7, M8 M9 are "standard , whereas proplnts T31, T32 T33 are experimental. Proplnts contg NC, NG NGu are listed here under Triple—Base Propellants (See below)... [Pg.431]

One of the older US mortar proplnts contained vaseline(petroleum jelly) which presumably acted as a stabilizer and flash-reducer. The compn of this proplnt was NC(13.15%N) 54, NG 43 vaseline 3%, with 0.5% DPhA added(US Spec 50-12-4A). Another older US cannon, proplnt contained TNT and hydrocellulose. Its compn was NC(12.6%N) 49, NG 20, TNT 20 hydrocellulose 10%. Here TNT was added for the same purpose as DNT(See under Single-Base Cannon Propellants). Hydrocellulose was used as flash-reducer. Its "cooling effect is due to development of large amts of gaseous products,... [Pg.431]

Heat Test minimum 30 mins Vapor Pressure at 60° O.OmmHg Volatility at 60° 0.0% and Water Produced on Explosion 140g/kg of NC Uses. Pyrocellulose has been used since the Spanish-American War(1898) in cannon and small arms proplnts. Historical development of "PyrpP proplnts is described under Cannon Propellants(qv). The original US single-base proplnts consisted of Pyrocellulose colloided with ether-ale, but beginning ca 1909, there was added 0.5% DPhA to act as a stabilizer and this amt was later incteased to 1%. This period also saw the introduction of the water-dry process which permitted manuf of proplnts in a fraction of the time reqd for the "air-dry process (Ref 44)... [Pg.500]

Uses. Blended NC is used in the manuf of single-base and double-base proplnts. Requirements of the US Armed Forces for NC s used in manufg proplnts are given in Specification MIL-N-244A(See also Cannon Propellant)... [Pg.501]
