+Gz Protection of a New Bladder Anti-G System
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.
