Abstract

Tests were conducted to determine the importance of footrests on ejection seats, using a 100 foot vertical ejection seat test tower and a mock-up which simulated the control wheel, instrument panel and rudder pedals of the B- 47B pilot's position. The paths followed by the toes and knees during ejection were varied by changing the catapult, size and weight of shoe and position of the leg at the time of ejection. Three principle test conditions were studied: a. Footrests removed, feet extended on rudder bar. b. Footrests removed, feet retracted against seat. c. Footrests in place, feet extended on rudder bar. Results were recorded by (a) high speed motion pictures (b) accelerometers placed on the man's hip and on the seat, and (c) time and distance magnet displacement to measure velocity. The subject was briefly examined before and after each test.
