Abstract:

This report describes an extension of a mathematical model previously developed to study the forces to which an ejection seat occupant is exposed during high-speed ejections. The forces which tend to dislodge two limbs from one another, or from a restraining surface are calculated to exceed 600 pounds for Mach numbers above 0.7. It is concluded that, for high angles of attack, a pilots musculo-skeletal system is not likely to withstand this tendency for dislodgement from a restraining surface and consequently, windblast and flail injuries are probable.
