Improved Armor/Helmet Protection

Military helmets and armor are designed based on costly and time consuming laboratory ballistic tests, firing range, and forensic data. The designer of military armor and helmets has to account for several factors including: weight, ballistic properties of the construction material, type of suspension and padding, balance, comfort, maintenance of vision and hearing, equipment and weapon compatibility, materials and manufacturing techniques, durability, and cost. Until now advanced medical imaging and computational modeling tools have not been adequately utilized in the design and optimization of military helmets and armor.

CFDRC has performed extensive (blunt) impact and blast wave simulation studies on the torso, head and helmet to analyze the influence of shock strengths, explosion distance, impact direction, role of the helmet for head protection, as well as the role of helmet elastic pads (foam) and suspension. Figure shows CoBi simulation results of a blast wave loading the head with helmet with enhanced distribution and size of elastic lining pads (foam).
