目的探讨新型抗荷系统的抗荷性能。方法以9名志愿者作为受试者,在离心机 +Gz增长率为3．0 G／s条件下完成5项试验。①分别测定KH-x抗荷服(KH-x)、DC-x高空代偿服 (DC-x)、FLH-x高空海上联合救生服(FLH-x)配KT-x抗调器的抗荷性能;②分别测定受试者穿 KH-x、DC-x、FLH-x时抗荷正压呼吸的抗荷性能;③分别测定受试者穿KH-x、DG-x、FLH-x时抗荷系统的抗荷性能;④分别测定受试者穿KH-x、DC-x、FLH-x时,进行抗荷正压呼吸并做PHP动作,在 +6．5 G;的持续耐受时间;⑤分别测定受试者穿KH-x、DC-x、FLH-x时,进行抗荷正压呼吸并做 PHP动作,在+9．0 G;的持续耐受时间。结果KH-x抗荷服、DC-x高空代偿服、FLH-x高空海上联合救生服与抗调器配套的抗荷性能分别达到2．11±0．44 G、2．25±0．40 G、2．11±0．55 G;抗荷正压呼吸(PBG)的抗荷性能分别达到2．13±0．58 G、2．04±0．09 G、2．10±0．14 G;抗荷系统的抗荷性能分别达到4．07±0．12 G、4．04±0．09 G、4．10±0．22 G;受试者采用本抗荷系统,并做PHP动作,均通过+6．5 Gz／45 s和+9．0 Gz／15 s。结论新型抗荷系统的抗荷性能明显提高,在作抗荷动作情况下可满足我国高性能战斗机性能要求。
Objective To study the anti-load performance of the new anti-load system. Methods Nine volunteers served as subjects and completed five trials at a centrifuge + Gz rate of 3.0 G / s. ①Kh-x, DC-x, FLH-x and KT-x anti-shock devices were measured respectively. The performance of anti-stress respiration was tested by KH-x, DC-x and FLH-x respectively. ③The KH-x, DG-x and FLH-x When the subjects wear KH-x, DC-x, FLH-x, anti-positive pressure breathing and do PHP movements, sustained resistance at +6.5 G; Subject to time; ⑤ were measured when the subjects wearing KH-x, DC-x, FLH-x, anti-positive pressure breathing and do PHP action at +9.0 G; sustained tolerance time. Results The anti-load performance of KH-x anti-suits, DC-x anti-suits and FLH-x suits combined with anti-shaker reached 2.11 ± 0.44 G and 2.25 ± 0 respectively. 40 G and 2.11 ± 0.55 G, respectively. The anti-load capacity of PBG reached 2.13 ± 0.58 G, 2.04 ± 0.09 G and 2.10 ± 0 respectively. 14 G; the anti-load system anti-load performance were 4.07 ± 0.12 G, 4.04 ± 0.09 G, 4.10 ± 0.22 G; subjects using the anti-load system, and do PHP moves through +6.5 Gz / 45 s and +9.0 Gz / 15 s. Conclusion The anti-load system performance of the new anti-load system is obviously improved. Under the condition of anti-load operation, it can meet the performance requirements of our country’s high-performance combat aircraft.
