Design and Development of Anthropometrically Correct Head Forms for Joint Strike Fighter Ejection Seat Testing

摘要

Anthropometric test manikins are commonly used in the assessment of head/neck injury potential of helmet systems during aircraft crashes or ejections. Current ejection test manikins use rudimentary heads developed long ago. Heads that are more representative of military aviators in the areas of shape, size, and inertial properties are required so that the helmets can be properly fit and evaluated. Surface scan and traditional anthropomorphic data were analyzed from the Civilian American and European Surface Anthropometry Resource (CAESAR) database to determine typical head sizes of people representing Case 1 and Case 6 anthropometries. Human cadaver head studies were also reviewed, and data were analyzed to estimate head mass property relationships for different sized heads. Representative mass properties were determined to characterize a 5th percentile female head weight, a 50th percentile small female head weight, and a 95th percentile male head weight. Representative heads were then chosen from the CAESAR database from which anthropometric manikin heads were developed and produced to better evaluate helmet systems.
