摘　　要：目的探讨离心机上新型囊式抗荷系统与PHP动作结合时的综合抗荷性能。方法 10名飞行员完成新型多囊式抗荷服的抗荷性能试验;6名志愿者完成新型囊式抗荷系统与PHP动作结合时的抗荷性能试验。结果 1)新型多囊式抗荷服抗荷性能为(2.60±0.17)G(P<0.01)。2)志愿者采用新型囊式抗荷系统+Gz耐力为(8.35±0.22)G,新型囊式抗荷系统抗荷性能为(4.40±0.14)G(P<0.01);志愿者采用新型囊式抗荷系统与PHP动作结合均通过9.0 G持续10 s,即新型囊式抗荷系统与PHP动作结合使用时的综合抗荷性能为(5.05±0.17)G(P<0.01)。结论多囊式抗荷服及新型囊式抗荷系统具有较高的抗荷性能,新型囊式抗荷系统与PHP动作有效结合,可满足高性能战斗机高+Gz防护需要。Objective To investigate the anti-G capability of a newly developed bladder anti-G system,and its integrated protection when combined with PHP maneuver.Methods 1） Ten pilots underwent the centrifuge tests for anti-G capability evaluation with the newly developed multi-bladder anti-G suit（MB）.2）Six volunteers went through the anti-G capability evaluation of the newly developed bladder anti-G system which mainly included MB,thorax-back bladder counterpressure vest（TB）,Pressure breathing for ＋Gz（PBG） and anti-G valve,and its combination with PHP maneuver.Results 1）The mean relaxed ＋Gz tolerance of pilots was（4.45±0.11）G.When wearing MB,their ＋Gz tolerance was（7.05±0.16）G.The ＋Gz protection provided with MB was（2.60±0.17）G（P〈0.01）.2）The mean relaxed ＋Gz tolerance of volunteers was（3.95±0.27）G.When the bladder anti-G system was used,their ＋Gz tolerance was elevated to（8.35±0.22）G.The anti-G capability of the bladder anti-G system was（4.40±0.14）G（P〈0.01）.All volunteers completed the test of 9.0 G for 10 s when the new bladder anti-G system was used with PHP maneuver together.The combination of the newly developed bladder anti-G system with PHP maneuver could provide a ＋Gz protection of（5.05±0.17）G（P〈0.01）.Conclusion The newly developed bladder anti-G system,including the multi-bladder anti-G suit,can offer a satisfactory ＋Gz protection.The combination of the bladder anti-G system with PHP maneuver can meet the demand for high ＋Gz protection of high performance aircraft.This study provides a scientific recommendation for the finalization of the advanced bladder anti-G system.
