The S-3A aircraft has a fuel range of six hours with an inflight refueling capability which sometimes requires 10-12 hour missions. In such long missions, it is of utmost importance that maximum comfort and alertness of the aircrewmen be achieved and maintained. A lumbar pad, designed by Lockheed- California Company which can be adjusted vertically, and pulsating seat cushion were proposed for the S-3A aircraft ejection seat in order to assure maximum comfort and alertness. The pulsating seat cushion was designed by H. Koch and Sons and qualified physiologically by the Naval Air Development Center NAVAIRDEVCEN. This report documents the ejection tower testing of both these items to determine their effect on ejection positioning and dynamic response of the aircrewmen during ejection. Human and dummy ejection tower tests were successfully completed on both items, which were subsequently recommended for use in the S-3A aircraft.
