In assessing the effectiveness of an extraction escape system, the motion of the crew member as he clears the cockpit is generally more important than his subsequent trajectory, particularly if we are concerned about the possibility of injury due to impact with the local structure, or injury due to limb flailing. The aerodynamic forces (and resulting deformation) of the extraction pendant, and the aerodynamic forces on the crew member, as the emerges from the cockpit, are the most important items, and these are analyzed theoretically in this report. Emerging crew member forces are also measured experimentally, using live human subjects in a wind tunnel simulation of extraction from an aircraft. A new extraction system concept - the ballistic extractor - is also analyzed, in a preliminary way, and is found to offer promise of avoiding the high speed ejection problems of rocket extraction systems. It should also be lighter, less expensive to develop and less expensive to build in quantity. (Author)
