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.
为给飞机开放式逃生系统的设计人员提供参数，对人体头颈部区域的空气动力学和生物力学特性进行了研究与分析。结果表明，在高速气流冲击过程中，人体头颈部区域对空气阻力、空气升力和空气侧向力的耐受极限分别为2.452 kN、1.358 kN和0.169 kN。同时给出了高速气流冲击耐受极限曲线。无论弹射时乘员姿势如何，除非作用于头颈部区域的空气动力在上述值范围内，人体头颈部区域不会受到气流冲击伤害。
