|
 | This study is to quantify, if possible, the hazardous effects of the machining variables. Initiation of an explosive is a thermal phenomena where input energy, regardless of its form (impact, shock, etc.), is converted to heat, increasing internal energy until an activation level is reached - an exothermic chemical reaction occurs providing heat for additional reactions to occur, continuing the cycle, until a 'runaway' condition exists. Therefore, if the effect ... |

| Non-Carcinogenic Replacements for PBNA Antioxidant in PBXN-105 and PBXN- 106 Explosives |

|
| Explosive mixes of PBXN-105 and PBXN-106 were prepared using Cyanox 2246 and CAO-14 antioxidants in lieu of phenyl-beta-naphthylamine (PBNA). Specification tests, as well as other related tests, were performed on the system. Findings indicate either of the antioxidants are suitable replacements. |

| Predicting High Explosive Detonation Velocities from Their Composition and Structure (II). Addendum |

|
| A previous technical report described a simple empirical relationship between detonation velocity at theoretical maximum density and a factor, F, that is dependent solely upon chemical composition and structure. The explosives ranged from nitro-aromatics, cyclic and linear nitramines, nitrate esters and nitro-nitrato aliphatics to zero hydrogen explosives, carbonless explosives and hydrogen rich explosives. Minor modifications have been made to the equations presented in that report, including a correction factor for ... |

| Reassertion of Composition A-3 in Projectiles |

|
| This report presents the results of a study to evaluate postpressing growth or dimensional changes observed in fuze cavities of Composition A-3 loaded 5 in. projectiles. Because of the introduction of improved press loading procedures during 1970, postpressing growth, or reassertion as it is generally called, is no longer a problem and the waiting time currently imposed between pressing and drilling the fuze cavity should be eliminated.

E. Yancey McGann; Lewis R. Rothstein; NAVAL WEAPONS STATION YORKTOWN VA
|
| This report is a safety, quality and cost effectiveness study of loading gun ammunition with Composition A-3 explosive. Processing parameters were required to increase gun firing safety and increase explosive load quality using material with a bulk density of less than 0.81 g/cc at the lowest possible cost. Each processing variable was investigated and a set of processing parameters was established within which the loading facilities could operate safely and ... |

| EVALUATION OF LOW COST ALUMINUM ALLOY GRANULES FOR USE IN ALUMINIZED EXPLOSIVES |
08 AUG 1969 |
|
| Authors:
Winona C. Hogge; NAVAL WEAPONS STATION YORKTOWN VA; NAVAL WEAPONS STATION YORKTOWN VA
|
 | This report covers the evaluation of low cost aluminum alloy granules for use in aluminized explosives, i.e. Tritonal, DESTEX and H-6. The alloy was evaluated with respect to its effects on batching characteristics, composition uniformity, thermal stability and impact sensitivity of the explosive systems. A comparison was made of the alloy and currently used atomized aluminum with respect to particle size and chemical composition. |
