Armor Protection for Pilot/Copilot Seat with Crash Safety Features for CH-47a Helicopter

摘要

Pilot/copilot protected crash-safety seat was designed and manufactured. Optimum seat and torso protection was attempted. Detail load and stress analysis for accelerations of 20 g vertically and 45 g longitudinally and laterally was made. By using crushable honeycomb type material, an improved torso restraint system and a variable attenuation mechanism were adopted. The feasibility of using protection media as a load bearing structure was demonstrated. (Author)
