A study was conducted to determine the amount of static pull that could be exerted in situ on the face curtain of the Martin-Baker Ejection Seat. To measure the pull, a hydraulic pressure measuring device was fabricated and attached to the curtain handles. A selected population of 252 subjects completed three maximum pulls each on the curtain. Mean age, weight, and height was 23.5 years, 163.7 pounds and 5 feet 9-34 inches respectively. The mean average pull of all subjects was 57.3 pounds with a standard deviation of 14.4 pounds. The absolute range for single trials was 17 to 107 pounds. It is recommended that further studies of dynamic pull on the curtain in situ, maximum pull under ideal conditions, and the effect of positive g on pull be made. Author
