新研囊式抗荷装备的抗荷性能

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％、65％和90％扩大覆盖面积抗荷服（45％ECGS、65％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、65％ECGS和90％ECGS的抗荷性能分别为2．50、3．38和3．63G；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／10s。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。

+GZ protection of the newly developed bladder anti-G equipment

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.
