Abstract

New helmet-mounted devices (such as night-vision goggles, laser eye protection, etc.) have created new safety hazards for pilots during ejection or high G maneuvering. In order to prevent the resulting head/neck injuries, this study extends the air-bag protection system developed for ground vehicles to a neck mounted system for aircrew personnel. Results, carried out by computer biodynamic simulations using the Articulated Total Body Model (ATB), showed that: 1) helmet weight had little effect on head/neck torque, contact force and flexion angle; 2) initial head/neck position and center of gravity offsets of the helmet-mounted devices had significant effects on head-neck torques, contact forces, and neck flexion angles; and 3) the neck mounted air bag significantly reduced neck torques, contact forces, and neck flexion angles. We conclude that the neck-mounted air bag system could significantly reduce the severity of head/neck injuries to pilots during ejection or high G maneuvering.
