An investigation is described which addresses the inertial loading effects of Head Mounted Devices HMD on aviator head-neck-spine dynamic response during high Gz acceleration exposure. The primary objectives of this study were to develop a methodology which could be used to establish limits on HMD inertial properties and to apply this methodology to the evaluation of the severity of the internal loads -- occurring in the neck and upper spine -- associated with certain specific HMD ensembles. This paper describes how the Head-Spine Model HSM, a highly discretized, 3-D mathematical representation of the human head-spine- torso structure, was used to 1 establish a set of baseline response criteria BRC 2 establish a preliminary methodology for setting limits on HMD inertial properties and 3 evaluate the severity of the loading associated with possible chemical defense CD ensembles.
