|
 | Lumped-parameter interior ballistics (IB) codes have had limited success in simulating the IB of mortars due to the complex nature of the firing event. Only near the end of the firing event does the mortar conform to the conventional ballistics model for which lumped-parameter codes were designed. Modified lumped-parameter models are capable of simulating some key mortar variables. There are significant pressure waves developed in mortars, which are due in ... |

| The characterization of Department of Defense (DoD) training lands for explosives residues involves sampling and analyzing soil samples collected at firing points and impact areas. Laboratory instruments used for this analysis are susceptible to accumulating high concentrations of these compounds, thus possibly requiring reanalyzing. By using the Expray Explosives Detection Kit to determine the approximate concentration of explosives compounds prior to analysis, soil extracts can be diluted to a concentration ... |

| On 20 December 1974, two hangfires occurred in a developmental 155-mm howitzer at Aberdeen Proving Ground (APG), MD. The second hangfire was accompanied by a rupturing of the howitzer breech. As a result of this, a laboratory study was initiated to uncover possible causes leading to the malfunction. The study involved testing of various components of the igniter train singly and in various combinations under a ... |

| Laboratory experiments and 30-mm-caliber gun tests have been pursued in order to explore the action time of the M230 gun using laser ignition. The laboratory tests explored the response of black powder (BP) to energy levels from 0.2 to 0.5 J. Tests with class 5 and class 7 BP show that response will probably not be fast enough to use BP as the primary initiator for ... |

| Chemical and gas-plasma treatments were used to modify chemical/ physical properties of carbon black powder commonly used to support platinum catalysts. Altered catalyst-carbon interactions affect catalyst-particle size, which can, in turn, affect catalyst activity and subsequent catalyst life. We have demonstrated that particle size of deposited platinum on carbon can be changed by carbon black pretreatments These modifications can be easily applied to carbon blacks used in fuel cells, high ... |

|
| Safe operation of a gun system incorporating multicomponent charges requires a good ignition system. One such proposed system for large-caliber guns involves the use of semiconductor bridge initiators (SCBIs) to commence the interior ballistic cycle. This simulator study demonstrated the feasibility of using SCBIs to simultaneously ignite multicomponent propelling charges. The flamespread simulator (76-mm I.D.) at the U.S. Army Research Laboratory, at Aberdeen Proving Ground, MD, was used to simulate ... |

|
| Semiconductor bridge initiators (SCBI) have been proposed as a means of initiating the ballistic cycle in large-caliber ammunition. However, an ignition delay of more than 10 ms for a black powder basepad was not acceptable for multicomponent tank ammunition. Enhancement of the output from the SCBI was needed to reduce the ignition delay to acceptable levels. Early experiments in a small-caliber ammunition simulator suggested that if the energetic igniter material ... |

| The inherent lack of rigidity and the complexity of bagged propelling charges and the associated ignition components can lead to incorrect alignment and/or assembly of the charge. A well-designed consumable case can alleviate these problems by assuring ignition system alignment and control of charge location within the chamber while simplifying the fabrication of the charge. A howitzer prototype consumable case was fabricated from available felted nitrocellulose components and test firings ... |

| The wear-reducing liner in the base-ignited XM201E2 charge failed to reduce the erosivity of the XM201E2 charge. When the clean-burning igniter (CBI) in the XM201E2 charge was replaced by black powder, the barrel life of 155mm howitzers firing the modified XM201E2 charge increased to 3,500 rounds from 1,000 rounds with CBI. Considerable gun barrel heating by igniter gases was observed during experiments conducted to ascertain why the wear rate of ... |
