Abstract: The Multifunctional Helmet is a fully modular, mission-tailorable system designed for military and non-military use to further enhance protection and comfort. The Multifunctional Helmet uses advanced human factors methodologies to form a new shape that allows maximum coverage and protection of the head, face, and neck. When fully integrated, the Multifunctional Helmet protects against a full range of personal threats. The Multifunctional Helmet offers five independent Modularities: 1) a fabric Skullcap to maintain thermal comfort; 2) a Bone Conduction Communication System that offers fully duplex communication housed within the Skullcap; 3) an Impact Liner that absorbs impacts and blunt trauma; 4) a Ballistic Shell that protects against ballistic fragments; and 5) a Helmet Add-on that ricochets small arms fire. The Ballistic Shells are to be produced using special aramid fabrics and resins, and are laser cut, vacuum preformed, and molded.
