后倾座椅与新型囊式抗荷系统综合防护性能研究

Study on comprehensive protective function of tilt-back seats and new bladder-type anti-G system

目的探讨后倾座椅与新型囊式抗荷系统的综合防护性能。方法在离心机3G／s的条件下，测定6名锻炼员分别在座椅后倾角13°、45°时采用新型囊式抗荷系统+Gz耐力。结果受试者采用新型囊式抗荷系统在座椅后倾角13°、45°时的抗荷耐力均可达到9G 10s，但座椅后倾角45°时心率、疲劳程度低，且有1名受试者的抗荷耐力达到了10G 10s。结论45°后倾角座椅与新型囊式抗荷系统的综合防护性能可达到10G。

Objective To explore the comprehensive protective function of tilt-back seats and new bladder-type anti-G system.Methods Under the condition of 3 G/s in centrifuge,+Gz tolerances were tested in 6 trainees with new bladder-type anti-G system respectively on 13° and 45° tilt-back seats.Results Under the two conditions,the anti-G tolerances of all subjects were as high as 9 G 10 s,but under the 45° condition,the heart rate and fatigue level were lower and anti-G tolerance of one subject amounted to 10G 1...
