BALLISTIC IMPACT FLASH

Abstract

The down range flash from the perforation of thin aluminum plates by steel and aluminum fragment simulators, one half inch diameter cylinders with hemispherical heads, was investigated to determine time, size, and temperature. By comparing the relative intensities of vibrational band structure in the A10 green system an effective vibrational temperature for the flash was determined to be between 3400 degrees K and 4100 degrees K. The overall dimensions of the flash were found to be approximately 14 inches in the axial direction and five inches in the transverse direction. The time duration was found to be between three and five milliseconds.
