Abstract��
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.
