【摘要】 目的　探讨新研制囊式抗荷装备的抗荷性能。　方法　 1在离心机 (+GZ增长率为1G/ s)上测定了 6名受试者的基础 +GZ耐力 ,分别采用 45 %、6 5 %和 90 %扩大覆盖面积抗荷服 (4 5 %ECGS、6 5 % ECGS、90 % ECGS)与 KT- 9抗调器配套时的 +GZ耐力 ,确定其抗荷性能 ;2在离心机(+GZ增长率为 3G/ s)上测定 10名飞行员穿 45 % ECGS配 KT- 9抗调器、并穿代偿背心进行抗荷正压呼吸及做抗荷动作时的 +GZ耐力。　结果　 45 % ECGS、6 5 % ECGS和 90 % ECGS的抗荷性能分别为 2 .5 0、3.38和 3.6 3G;飞行员穿 45 % ECGS进行抗荷正压呼吸及做抗荷动作时的 +GZ耐力可达到9G/ 10 s。　结论　新研囊式抗荷装备的抗荷性能比现役抗荷装备明显提高更多还原

【Abstract】 Objective To investigate +G Z protection of newl y developed bladder anti-G equipment. Methods Six young volun teers and 10 fighter pilots served as subjects. In volunteers, the relaxed +G Z tolerance and +G Z tolerance using newly developed 45%, 65% and 90% ECGS (exte nded coverage G-suit)) together with KT-9 valve were measured by centrifuge wi th onset rate 1 G/s. In pilots, the +G Z tolerance test (up to 9 G for 10 s ) us ing 45% ECGS together with KT-9 valve, NDB vest and pressure breathing for G, a s well as anti-G straining maneuver was performed using centrifuge with onset r ate 3 G/s. Results The additional +G Z protections of 45% EC GS, 65% ECGS, 90% ECGS together with KT-9 valve were 2.50 , 3.38 and 3.63 G re spectively. All the 10 pilots can complete the +G Z tolerance test up to 9 G fo r 10 s. Conclusions The newly developed bladder anti-G equipm ent can offer satisfactory +G Z protection. Its additional +G Z protection is significantly higher than that of anti-G equipment used at present.更多还原
