摘要
目的研究人上肢有／无防护时耐受高速气流吹袭限值；为防护装置的设计要求提供试验依据。方法进行了飞行员上肢抗拉耐力研究；采用人尸体、活猕猴上肢开展了模拟气动载荷耐受限度的研究；进行了人尸体、猕猴上肢生物力学特性研究和1／5人椅模型跨超声速风洞试验。结果通过系列的试验研究和国内外资料分析,获得了人上肢有／无防护时耐受高速气流吹袭的限值。结论为高性能战斗机飞行员上肢弹射救生的生理要求及上肢高速气流吹袭防护装置的设计、鉴定和验收提供了实验依据。
Objective To study the tolerance limit of crewman＇s arms to windblast with and without protective devices. Method Multidisciplinary researches were done, namely： tensile test of pilots arm to simulated aerodynamic force; study on tolerance limits of cadaver arm and live monkey foreleg to simulated aerodynamic force; study of biodynamic characteristic of cadaver arm and live monkey foreleg to simulated aerodynamic force; wind tunnel test of a 1/5 scale crewman/seat model and subjects. Result The tolerance limit of crewman＇s arms to windblast with and without protective devices were obtained through a series of above-mentioned experimental studies and analysis of data both at home and abroad, and windblast protection requirements for crewman＇ s arms were presented. Conclusion The study gives a basis for design, authentication and acceptance test of crewman windblast protective equipment and ejection escape safety evaluation of future high-performance fighters.
