Some Studies Relating to 'Limb Flailing' After an Emergency Escape from an Aircraft.
Abstract
When a crew member ejects in an open escape seat, his limbs may become dislodged from the seat and forced to trail behind him. Injury may result. The study described in this report is concerned with discovering the basic mechanisms of flail injury, and determining the loads which cause limb dislodgement. Simple dynamic concepts and models are presented together with the results of wind tunnel measurements of body segment forces. Tunnel tests were limited to the symmetrical case of zero pitch and yaw. Wind tunnel measurements were also made of body segment forces in simulated Tractor Rocket Egress System body positions. In all cases, live human subjects were used. It is believed that flail injury can be prevented, and several solutions are suggested.
