一种改善飞行员抗荷服性能的新方法

在管式抗荷服的腹囊和两侧管囊间分别装上分压装置和泄压活门,将腹囊内的压力降至管囊内压力的40%左右.在管式抗荷服研制中采用这种新型的分压技术,克服了飞行员穿着时的腹部压痛问题,改善了其舒适性,提高了飞行员的正向过载防护能力.具有分压装置的新型抗荷服进行了10人次的离心机生理试验,在过载增长率3?G/s、最大试验过载9?G条件下,分压装置工作正常,装备抗荷效果达到了3.5?G.对60名歼击机飞行员调查表明,分压装置和泄压活门的大小、安装部位及其舒适性均可接受.该技术已用于其它新型管式抗荷服的设计中.

Novel approach to improving the performance of anti-G suit for pilots

Pressure decrease device and pressure discharge valve were separately put between abdominal bladder and capstan bladder in capstan anti-G suit and then the pressure in the abdominal bladder was reduced to approximately 40% of the capstan pressure.The novel pressure decrease technique was applied in developing capstan anti-G suit so that the problem of tenderness on abdomen of pilots could be overcome, the comfort and +G_z protection capability for pilots were improved. Centrifuge evaluation of a new model anti-G suit with pressure decreasetechnique was undertaken and 10 male centrifuge subjects were used. The device run perfectly when the subjects were exposed to +9?G maximum profiles at acceleration onset rate 3?G/s and the average acceleration protection value of the anti-G equipment was above 3.5?G. 60 fighter aircraft aircrew comments after donning/doffing the suit show that the size of the device and discharge valve, their installation position and comfort on abdomen are acceptable. The technique is also used in developing other new capstan anti-G suits.
