Estimation of Priming Mixture Force

This paper presents the results of estimation priming mixture force for primers used in 12.7 mm ammunition. The method is based on pressure measurements a closed chamber into which products combustion flowed. capacity was changed by inserting sleeves various volumes. Another value performed using earlier investigations filled with glass balls. determined values were compared estimated accessible literature data. obtained estimations are same order magnitude as black powder. justifies use powder characteristics assessment thermodynamic properties interior ballistics calculations. time action investigated primer optical recording outflow an open space. To facilitate interpretation experiments, theoretical model used.
