Abstract
Gun propellants of reduced sensitivity to the impact of shaped charge jets are today in the center of interest. A great number of procedures are proposed to compare the sensitivity of different propellant types, but a deeper insight into the mechanisms of the initiation of the reaction would be desirable. Therefore, an investigation method has been developed at EMI to measure pressure and ionization inside the propellant bed at shaped charge jet impact which in combination with x-ray photographs of the grain distribution allows to assess propellant response to jet impact. The method is described and results with propellants showing weak and strong reactions are shown.
