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 1 0～ 1 5s的梯形 +Gz曲线后 ,再暴露于 + 5～ 9Gz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 .2 6G ,均顺利通过了 + 5～ 9GzSACM ,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 。
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.
