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。

Objective To explore the injury degree of human head induced by through the canopy ejection, and find out a proper physiological parameter for engineering use. Methods Dynamic impact tests with a pendulum type equipment and aquasi static compression tests using a material test machine were performed on 17 skulls and drop hammer impact tests on lower ends of 8 femora were carried out.A dummy was used for measuring the force produced during ground through canopy ejection and rocket trolley experiment. Results It was found that impact peak force lower than 3.5 kN or duration less than 30 ms did not result in fracture of skull.Calvarium can withstand slowly and well distributed acting force up to 6.9 kN, while the basis cranii can withstand 1.5 kN. The lower end of femora can withstand impact peak force up to 8 kN without fracture. Conclusion The head impact injury is the main hazard in through the canopy ejection. The force which calvarium can tolerate is much higher than that of basis cranii. If canopy piercer is used, through canopy ejection will not likely cause injury.

目的探讨穿盖弹射对人体头部、膝部的损伤程度,以提出适宜的生理参数,供工程部门使用。方法用17具头颅骨在摆锤式冲击台上进行动态冲击试验,在材料试验机上进行准静态压力试验,观察试验后颅骨骨折情况。在落锤式冲击台上进行8具膝部冲击实验。用假人进行地面弹射、火箭滑车实验,测试假人与舱盖碰撞的外力值。结果外力峰值不超过3.5kN或作用时间不超过30ms时颅骨没有发生骨折。颅盖骨可承受6.9kN以下的缓慢均匀加压,颅底骨只可承受1.5kN。膝部承受8.0kN冲击力时无损伤发生。结论穿盖弹射时对人体主要的威胁是头部碰撞伤,颅盖骨承受的破坏力值比颅底骨大得多。破盖器工作时人体与舱盖碰撞的机率很小,且不易发生损伤。膝部可承受较大的穿盖力,不致发生损伤
