How a G suit works

When Fighter pilots are in combat they experience G-forces when making sharp turns

These Forces cause Hypoxia which is when blood pools in lower areas of the body, leading to the Brain being deprived of blood causing pilots to blackout

The G suit is designed to constrict the lower half of your body and force the blood upward to keep circulation of blood going throughout the body

History

Around World War II planes became so advanced that the pilots would pass out during flight because they couldn't’t handle the G Forces on there body

Dr. Wilbur Franks was the first to come up with the idea of G Suit

The suit was designed to pump water into the bladders and constrict the body in aid of keeping pilots conscious

History cont.

Unfortunately Dr. Franks design proved to be heavy and impractical in desert and topical climates

Dr. Earl Wood and small team of scientist’s continued research on the G suit and perfected the design

Instead of using water to inflate the bladders they used pressurized air which made the suit lighter and more confortable for the pilots

Preview Control

Automated system where the movement of the control stick is used to predict what the G force on the aircraft will be ahead on time.

Then a computer determines what pressure is needed in the suit to safeguard the pilot at that G-force

Not only used for pilots

G Suit can also help with people with Orthostatic Intolerance

When a normal person stands, approximately 750 ml of thoracic blood is abruptly translocate downward. People who suffer from OI don’t have the basic mechanism to compensate for this deficit.

With the help of old modify G-suit people with OI can compensate for not being able to pump the blood on their own.
