Abstract:

A model of a seated human subject and ejection seat is proposed. The body is represented by a lumped parameter system consisting of five masses. The aerodynamic and dynamic forces, deflections and trajectories of this body are calculated for two zero speed and two high speed ejections, using different rocket characteristics. The adverse effects of suddenly applied accelerations is very evident when compared with constant acceleration. The model and the computer program described in the report may readily be adapted to further studies of ejection from high speed aircraft including limb flailing, rocket thrust characteristics, etc. Author
