ESTIMATING DRAG AND CHARACTERISTICS OF VBIED FRAGMENTS

摘要：

Fragments from a VBIED fall into two categories; preformed and thin-plate fragments. Thin-plate fragments are deformed and may not be described using existing drag coefficient curves. Using high-speed video footage from full-scale experiments, key fragment variables are determined and used to examine the applicability of existing drag coefficient curves to such fragments. To improve predictions of the throw distance, new drag coefficient curves are developed through finite-element simulations using ANSYs AUTODYN. The new drag coefficient curves and better area estimation techniques enable us to improve predictions significantly.
