Abstract : A summary of the investigation leading to the fabrication of a prototype model of a head and neck protective system for aircrew members is presented. The system provides impact, vibration and environmental protection for the wearer from 0 to over 82,000 feet altitude. The system consists of a helmet and a pneumatically operated neck restraint device which is used to stiffen the coupling between the helmet and the wearer's torso during vibration and acceleration environments.
