应急弹射中高速气流引起的上肢甩打伤愈来引起人们的重视。本文介绍了通过高,低速风洞、空中弹射、火箭滑车等一系列实验,得到了人体在从低速到高速的迎面气流作用下手臂气流解脱力系数;地面模拟实验,测置了飞行员手臂抗拉耐力;零—零弹射实验,测量了弹射动力产生的手谱解脱力。对实验结果综合分析,得出了在不同高度、不同速度弹射时,上肢气流解脱力及手抓不住弹射击发手柄时耐受限。目前尚未见到国外的系统、完整的手臂耐力研究的报导。
Emergency ejection in the upper limbs caused by high-speed airflow rejection more and more people’s attention. In this paper, a series of experiments of high and low speed wind tunnel, air ejection, rocket pulley and so on were carried out to obtain the coefficient of relieving force of arm airflow under the action of head-on air flow from low speed to high speed. The ground simulation test measured the tensile strength of pilot’s arm Endurance; zero-zero ejection experiment, measuring the ejection force generated by hand spectrum relief. The results of a comprehensive analysis of the experimental results obtained at different altitudes, different speed ejection, upper extremity airflow relief and unable to grasp the firing shot handle tolerance. No systematic, complete arm endurance study has been reported yet.
