Here, a radiographic methodology is presented which can measure the relative penetration efficiencies of different portions of a perforator jet. This knowledge can quantify the penetration efficiency of individual portions of a jet into specific target materials and thus identify design opportunities for improvement in perforator charge performance. The test methodology is a modification of a test configuration previously developed to characterize the erosion of a shaped charge jet when penetrating different thicknesses of drilling mud. By replacing the drilling mud with concrete or other target materials of interest, perforator jet erosion rates can be directly measured as a function of discrete target thicknesses. The test configuration and data obtained from the drilling mud tests are described to illustrate the output attainable from the test configuration, followed by a discussion of the technique adapted to quantify perforator effectiveness in specific target materials of interest.
