气流吹袭时飞行员手臂的受力分析

总结了测量作用在手臂上的气动力的实验结果.。这些实验是用风洞、火箭车和空中弹射进行的。用6名男青年、橡胶假人、1/2人体木模型和1/10人体钢模型,在Ma=0.086～2.04范围内,测量了作用在手臂上的气流解脱力。用这些实验数据,计算出了气流产生的手臂解脱力系数,并推导出这些系数与Ma数之间的关系式,为进一步推导飞行员手臂对气流吹袭的耐力提供了气动力数据。

THE CHARACTERISTICS OF AERODYNAMIC FORCE ON CREWMAN ARMS DURING WINDBLAST

This paper summarizes the results of experimental research accomplished to determine the aerodynamic forces acting on the crewman arms. These experiments were conducted in the wind tunnels, on the rocket sled and by ejection from aircraft. The dislodgment forces on the arms were measured on 6 young men, a dummy, a 1 / 2 scale body model and a 1 / 10 scale body model over the range of Mach numbers from 0.086 to 2.04. By using these data collected from these experiments, computed the coefficients of the dislodgment forces on the arms were and the relationship between these coefficients and Mach numbers was obtained.
