G.Force, you might familiar with this term. when you are in the giant wheel, little G-force can be experienced. But this is very small amount, we can not even sustain this small amount of G-force, then think about the Astronauts and fighter Pilots. they has to sustain the G-force of amount 3G to 10G.
Earth gravity is 9.8 m/s2.
3G = 3 * 9.8 m/s2
now imagine 10G = 10* 9.8 m/s2
At this higher G-force our blood pressure goes to higher, and sometimes it leads to death.
There are two types of people experienced this G-force on a regular basis. Astronauts and fighter plane pilots.
Astronauts experiences when they are taking-off and re-entry situation. particularly when they re-entry.
when Astronauts re-entry to the earth atmosphere their space shuttle velocity is about 28,000 km/hr, this is hypersonic speed. at this situation they experience 10G.and their blood pressure is higher. To withstand this force they ware G-Suits.
How G-suit work : The suit is only pair of Chaps that has a waist that wraps around your gut. It has a hose that plugs into the aircraft which forces compressed air into bladders built into the suit. When the aircraft makes tight turns, causing g loads on the pilot, it forces the air into the lower legs, thighs, and gut area to force blood back up into the torso and to prevent it from pooling into your legs.
If they lose too much blood from their head under these loads they will lose consciousness and pass out. Once they pass out they will lose control and risk crashing. The G suit does not do all the work however, it only helps. The Astronaut in the spacecraft still has to do an enourmous amount of work to retain consciousness. They must flex the muscles in their legs and abs as hard as he can and take short, forced breaths.
