摘要
本文介绍了1:10人椅模型上肢跨-超音速风洞实验的结果。测量了Ma=0.5～2.04和攻角10°～20°范围内上肢的阻力和侧向力。获得了在握扶手和拉中央环两种姿态下手臂的气动力特性。比较了穿衣袖与不穿衣袖两种状态下手臂的气动力数据。实验结果为确定人体上肢对高速气流吹袭的耐久限度和设计防护措施提供了重要的气动力数据。
The results of wind tunnel tests of upper arm fo a 1/10 scale model crewman and ejection seat at transonic-supersonic speed were presented in. the paper. Drag and lateral forces on upper arm were measured at freestream Mach number from 0.5-2.04 and incident angle from 10°-to 20°.The aerodynamic characteristics of upper arm in the attitutes of grasping side and seat pan ejection handle initiator were obtained. Aerodynamic data on upper arm were compared under the conditions with and without cloth. The paper presents the important aerodynamic data for determining tolerance of human upper arm of wind-blast and designing a airciew windblast protective device.
