摘　　要：为了研究弹射过程中人体肢体的气动特性和防护方案的有效性 ,在 1 .2m×1 .2m跨超声速风洞中进行了人椅组合模型肢体测力和局部压力测量试验研究 ,试验的M数范围为 0 .4～ 2 .0 ,迎角范围为 5°～ 30° ,侧滑角范围为 0°～ 90°。结果表明 ,这次试验是成功的 ,所研究的防护装置都是有效的 ,侧滑使背风侧肢体被吹开的趋势增强 。In order to investigate the effectiveness of tested protective methods and limb aerodynamic characteristics in the process of ejection, left limb force measurements and local pressure measurements on a crewman/escape seat combination model have been conducted in 1.2m × 1.2m transonic and supersonic wind tunnel over Mach number ranges 0.4 to 2.0 , angles of attack 5° to 30°, sideslip angles 0° to 90°. Test results show that the test is successful, tested protective devices are effective, sideslip generally heighten the tendency of leeside limbs away, boosting leg has unfavorable effects on aerodynamic characteristics of limbs.
