g load (1 Viewer)

[clever angel]

hi ppl,

what was the maximum g load experienced by an Apollo crew?

 

[wanton-wonton]

g-force? 6? I'm guessing.

 

[jamesy_1988]

NASA tries to keep it around 3-4 but i would not be suprised it if gets higher

[Numero Uno]

yeah nasa keep it to 4 max

but alen sheppard experienced about 8 .. when they were testing it out

 

[velox]

Yeah after 4, things start to get a little nasty if experienced even for a short amount of time

 

[Xayma]

No things don't get too bad at 4 for short amount of times. Considering they force them to undergo G-forces that push them unconcious in training.

But yeah they don't reach too much, fighter pilots often go over it.

 

[velox]

Hmm i read somewhere that at 4g, for 45 seconds u can experience a red out or a black out, depending if ur going into a dive or pulling out.

 

[Numero Uno]

yeah .. but the maximum human tolerance .. i heard was 8 ..

but u experience other sensations before this

I know that ordinary people can sustain up to 4 gs for short bursts (The tower of terror pulls about 4 gs in Dreamworld, I think the Space Probe pulls about 3). I know that fighter pilots can pull 9 g without blacking out, but they use special anti-g suits, and are trained to brace themselves, tense up and are generally stronger. I rememeber watching a documentary where they launched this guy in a rocket sled, and he ended up pulling about 19g. Nothing happened to him though. BUt yeah i think space shuttle would not be more than 4 most of the time.

Well it isn't that Fighter pilots use the suits, it's that they occasionaly have >13g on them. If they eject even the suit doesn't help.

And the astronauts sitting position (so they are laying down effectively) performs the same function as the suit.

Amazing

In my Physics text book it has a bit on the highest 'g' force experienced by a human.
In 1959 R. Flanagan Gray a physician for the U.S. Navy's centrifuge laboratory tested himself the centrifuge at an amazing 31g for five seconds. This is no typo it is 31g

Not something that i would like to do every day

He cheated. He was in a tank filled with water.

 

[rama_v]

lol Maybe, but ppl live through being ejected out of a fighter jet (I read more than 20 g at howstuffworks.com )

 

[jamesy_1988]

he still experienced 31g. weither he was in water or not it was 31g

he's lucky not to be dead
