人头颈部耐受高速气流吹袭限值(英文)

Tolerance Limit of Human Head neck Region to High Speed Windblast

研究了人头颈部的气动特性和生物力学特性，提出人头颈部受到高速气流吹袭时，对气动阻力的耐受限值为２．４５２ｋＮ，对气动升力的耐受限值为１．３５８ｋＮ，对气动侧力的耐受限值为０．１６９ｋＮ，并给出了人头颈部高速气流吹袭的耐限曲线。不论乘员在何种姿势下弹射，作用在头颈部的气动力不超过以上数值才可免遭高速气流吹袭造成的损伤。

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 2.452kN, 1.358 kN and 0.169kN 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.
