Influence of Helmet Inertial Properties on Neck Injury Risk During Ejection: A Numerical Human Model Approach

Survival rate after jet ejection is about 94%, but 50% of major injuries are due to neck injuries. Mechanical parameters responsible for those injuries are not yet fully understood. The purpose of the present study is to use a existing finite element model to investigate helmet mass and inertial properties influence on neck injuries that may occur during ejection.
