目的 研究以新型囊式抗荷系统、无胸部代偿的抗荷加压呼吸及PHP动作组成的新型综合抗荷措施防护效果;探讨采用该措施进行防护时伴有的疲劳、疼痛等问题. 方法 6名被试者在载人离心机上进行了5组+Gz暴露试验,分别为:1)基础+Gz耐力试验 (relaxed tolerance):测定被试者不使用抗荷装备,不做抗荷动作时的+Gz耐力.2)FLH-x联合救生服配KT-x抗荷调压器试验(FLH-x+KT-x):测定被试者穿FLH-x联合救生服配KT-x抗荷调压器时的+Gz耐力.3)FLH-x+KT-x+PBG试验(PBG):测定被试者穿FLH-x联合救生服配KT-x抗荷调压器,戴TK-x保护头盔、YM-x加压供氧面罩配YTQ-x氧气调节器进行抗荷加压呼吸时的+Gz耐力.4)6.5 G持续45 s试验(6.5 G 45 s):被试者使用与第3组试验相同的抗荷装备,进行+6.5 Gz持续45 s的暴露.5)9.0 G持续15 s试验(9.0 G 15 s):被试者使用与第3组试验相同的抗荷装备,做PHP动作,进行+9.0 Gz持续15 s的暴露.在每次试验结束后用主观量表记录被试者疲劳及疼痛的程度.结果 试验中没有发生G-LOC (G-induced lose of consciousness).FLH-x联合救生服配KT-x抗荷调压器的抗荷效果为2.5 G;PBG的抗荷效果为1.67 G;被试者均完成了6.5 G持续45 s及9.0 G持续15 s试验.试验中被试者的颈、腰、臂及手部在+Gz暴露时均出现过疼痛.结论 新型综合抗荷措施可以满足现代高性能战斗机的高G防护需要;该措施还应在高G导致的疼痛及颈部损伤的防护方面加以改进.
目的 研究以新型囊式抗荷繫統、無胸部代償的抗荷加壓呼吸及PHP動作組成的新型綜閤抗荷措施防護效果;探討採用該措施進行防護時伴有的疲勞、疼痛等問題. 方法 6名被試者在載人離心機上進行瞭5組+Gz暴露試驗,分彆為:1)基礎+Gz耐力試驗 (relaxed tolerance):測定被試者不使用抗荷裝備,不做抗荷動作時的+Gz耐力.2)FLH-x聯閤救生服配KT-x抗荷調壓器試驗(FLH-x+KT-x):測定被試者穿FLH-x聯閤救生服配KT-x抗荷調壓器時的+Gz耐力.3)FLH-x+KT-x+PBG試驗(PBG):測定被試者穿FLH-x聯閤救生服配KT-x抗荷調壓器,戴TK-x保護頭盔、YM-x加壓供氧麵罩配YTQ-x氧氣調節器進行抗荷加壓呼吸時的+Gz耐力.4)6.5 G持續45 s試驗(6.5 G 45 s):被試者使用與第3組試驗相同的抗荷裝備,進行+6.5 Gz持續45 s的暴露.5)9.0 G持續15 s試驗(9.0 G 15 s):被試者使用與第3組試驗相同的抗荷裝備,做PHP動作,進行+9.0 Gz持續15 s的暴露.在每次試驗結束後用主觀量錶記錄被試者疲勞及疼痛的程度.結果 試驗中沒有髮生G-LOC (G-induced lose of consciousness).FLH-x聯閤救生服配KT-x抗荷調壓器的抗荷效果為2.5 G;PBG的抗荷效果為1.67 G;被試者均完成瞭6.5 G持續45 s及9.0 G持續15 s試驗.試驗中被試者的頸、腰、臂及手部在+Gz暴露時均齣現過疼痛.結論 新型綜閤抗荷措施可以滿足現代高性能戰鬥機的高G防護需要;該措施還應在高G導緻的疼痛及頸部損傷的防護方麵加以改進.

Objective To observe the protection effects of a new combined anti-G measure, which is composed of new bladder anti-G system, unassisted positive pressure breathing for G (PBG) and PHP maneuver. The problem of fatigue and pain when using this measure is also discussed. Method Each of the six fully qualified centrifuge subjects experienced 5 groups of centrifuge runs:1) relaxed +Gz tolerance without anti-G equipments and PHP maneuver;2) +Gz tolerance with FLH-x+KT-x;3) +Gz tolerance when performing PBG with FLH-x, KT-x, YM-x and TK-x;4) +6.5 Gz for 45 s using the same anti-G equipments as the 3rd group;5) +9.0 Gz for 15 s using the same anti-G equipments as the 3rd group and performing PHP maneuver. Result There were no incidents of G-induced loss of consciousness in this study. The protective effects of FLH-x+KT-x, PBG and PHP maneuver were 2.5 G, 1.67 G and 1.23 G respectively. All the subjects had accomplished the 6.5 G 45 s and 9.0 G 15 s runs with the new combined anti-G measure. The pain occured on neck, waist, arm and hands. Conclusion The new combined anti-G measure can provide enough anti-G protection for modern high performance aircraft. How to prevent the occurrence of neck injury and alleviate the pain induced by G when using this measure needs further investigation.
