Physiological Studies On Advanced Bladder Anti-G System Of High Performance Fighter Aircraft

Current high performance fighter aircraft is capable of generating sustained levels of positive acceleration (+Gz), which have the following features: rapid onset rate(6 G/s), high +Gz (+9 Gz), sustained for longer time (15～45 s) and repeated appearance. The current standard anti-G suit(SGS) does not provide optimum protection to counter this high +Gz. Pilot can suddenly occur G-induced loss of consciousness (G-LOC) during high +Gz, which threatens flying safety of high performance fighter aircraft. For example, it has been reported that, a total of 18 incidents due to G-LOC occurred in the U. S. Air Force during 1982-1990. Therefore, how to ensure flying safety during high +Gz, remains one of the most important problems concerned by the aeromedical science community.During the last two decades, measures to enhance +Gz tolerance of pilots and to prevent the occurrence of G-LOC were actively explored in some countries, like US, UK, Sweden, France, Canada, and Russia(former Soviet Union). These efforts were mainly concentrated in the following two aspects. Firstly, from the point of how to enhance the +Gz tolerance of pilots by themselves, problems like selection, anti-G training and physical training, etc., for high performance fighter aircraft pilots have been extensively studied and advanced protocols and measures have...
