Design requirements for windblast limb protection systems to be used in current ejection seats were defined. The ACES II system was used as a baseline system. Using the baseline seat and the requirements, three arm and three leg restraint concepts were defined. A proposed program was then defined to evaluate and develop the proposed systems. Design requirements were derived from a list of criteria or constraints for the system as defined in the reference to the escape, aircraft, crew flight conditions and using commands' needs. Resulting requirements were then rank ordered and significant interactions between them identified. Identification of negative interactions highlights the significant trades necessary to design a successful windblast protection system. Ejection events and the resulting environment the crew is exposed to were then analyzed to define the physical actions the men and system must contend with. Review of previous ejection injuries and limb restraint systems was included to further refine the understanding of injury mechanisms. Specific injujry mechanisms of the knees, shoulder, elbow, and spinal column are presented.
