| 摘 要： | 目的在离心机上,研究新型囊式抗荷系统的抗荷性能,评估其抗荷作用.方法
6名男性被试者采用本囊式抗荷系统不做抗荷动作(AGSM),暴露于10～15 s的梯形+Gz曲线后,再暴露于+5～9
Gz 模拟空战动作曲线(SACM) ,并伴随腿部适度收紧.结果得到了该先进囊式抗荷系统的+Gz防护作用和被试者的+Gz时间耐力.本抗荷系统的抗荷效果为5.33±0.26
G,均顺利通过了+5～9 Gz SACM,且用力程度和疲劳程度均较低.结论本抗荷系统+Gz防护效果良好,其配套方案可行.

| Abstract: | Objective: A new bladder anti-G system was developed to get better +Gz protection. The purpose of this study was to assess the +Gz protection afforded by it on the centrifuge. Method: Six male subjects using the new bladder anti-G system were exposed to 10-15 s ladder-shaped +Gz profiles without anti-G straining maneuver (AGSM), then exposed to + 5-9 Gz simulated aerial combat maneuver (SACM) with leg straining. Result: The +Gz protection and the +Gz-time tolerance were obtained. The anti-G effectiveness of the advanced bladder system was 5.33 +/- 0.26 G. All subjects passed the +5-9 Gz SACM, but the effort and fatigue were lower. Conclusion: The +Gz protection afforded by this system is high. The suggested scheme of the new bladder anti-G system is feasible. |
