Abstract

To provide parameters for designers of open type escape system in an aircraft, aerodynamic and biomechanical characteristics of human head-neck region was studied and analysed. The results show that tolerance limit of human head-neck region are 2.452 kN, 1.358 kN and 0.169 kN to aerodynamic drag, aerodynamic lift, and aerodynamic side force respectively during high speed windblast. Meanwhile the curve of tolerance limit to high speed windblast is given. Regardless of crewman posture during ejection, human head-neck region is free from windblast injury unless the aerodynamic force exerted on the head-neck region is within the above-mentioned value.
