Abstract
Ballistic impact flash plays a pivotal role in the ignition of fires in military vehicles. Flash duration, geometry, and energy profiles are critical variables in the assessment of ballisticinduced fires. The survivability community has identified a need for a standardized data collection methodology and corresponding valid, community-verified, models. This article summarizes an effort by the Aerospace Survivability and Safety Operating Location (46 TG/OL-AC) at Wright-Patterson Air Force Base to quantify existing test data and produce an enhanced flash characterization model. Test data included high-speed video and flash intensity measurements using photodiodes. This article provides a description of the methodology used, the tool that was developed, and the results that were obtained. In addition, an effort to develop dynamic models for flash geometry and temperature profile based on projectile and target material properties and impact conditions will be described.
