Propellant Profiles Handloader Magazine This module discusses gunpowder and other explosives from a forensic chemistry perspective. it begins by explaining the history and types of gunpowder, including black powder and smokeless powder. We present the applicability and capabilities of utilizing irtd dart ms in conjunction with principal component analysis (pca) for the detection and differentiation of black powders and various bps from wipe based sample collections.
Propellant Profiles Handloader Magazine The paper presents an attempt to determine the dynamic vivacity functions of propellants with taking into account a parallel burning of the black powder igniter and the tested propellant. The authors would like to thank cindy wallace at the bureau of alcohol, tobacco, firearms, and explosives for providing the black powders and black powder substitutes, as well as karlijn bezemer and arian van asten at the netherland forensic institute for providing the firecracker test samples. For this reason, the importance of the analysis of organic compounds is leading to the adoption of a different set of analytical methodologies, mostly based on spectroscopy and chromatography. Dried residues from water or methanol extracts of suspected black powder or black powder substitutes may be analyzed to determine the presence of sodium benzoate, dicyanodiamide, potassium.

This paper presents the results of a comparative study on the respective effects of two ignition methods, i.e. gunpowder ignition and plasma jet ignition methods, on the ballistic properties of a single base propellant. Abstract: rimental black powder burning law finding. this method issues from records acquired during black powder charge burni g tests in closed vessel (ballistic bomb). evaluation of data sets brings courses of parameters needed for calculation of instant neous values of black powder burning rate. the burning law is then given as spar. The possibility of runaway pressures caused smokeless powder to destroy many firearms designed for black powder and required much more precise measurement of propellant charges. In some cases, particularly when the energetic material is especially critical, e.g., black powder, it may be necessary to conduct tests on each individual production batch as a preliminary check on suitability for the particular role required of it.
