G-suit
The G-suit is a special Vêtement used mainly by the pilot of hunting and the Spationaute S, intended to prevent the appearance of the phenomenon called black Voile, noted as of the First World War during the aerial combats. The powers and Maneuverability S of the aircraft quickly increasing, it quickly became essential to protect the pilots to enable them to carry out air operations (like the Ressource S) inducing load factors very high.
History
The principle of the G-suit was imagined in 1941 by Canadian Wilbur R. Franks of Toronto. Several scientists contributed to his improvement among which the American neurophysiologist EH Lambert.
Principle of operation
At the beginning it consisted of a simple tight girthing of the lower part of the body (thighs in particular) to prevent that blood does not accumulate there, causing a bad irrigation of the brain, resulting in a loss of consciousness.Another technique usually employed consists in pressurizing the body using compressed air.
Certain sources quote the Girafe like the animal presenting of the physiological characteristics to the source of its invention (how to drive back blood with several meters height). The same principle was to undoubtedly exist at the Diplodocus.
The principle of operation of the modern combinations developed amongst other things in Germany under name Libelle (Dragonfly in German) is copied on a phenomenon observed in particular in these insects whose very jerked flight subjects the body of accelerations which can go up to 30 G.
The combination contains a liquid circulating freely and coming to compress the low parts of the body. A pilot equipped and trained can resist Accélération S of 10 G before losing consciousness.
