What is the maximum G-force a human can endure without injury of death?

Answer 1

the healthy human body with some practice at pulling g, could withstand only a few seconds at more than 10 g before passing out from lack of blood flow to the brain. Or, more aptly, the lack of oxygen to feed the brain that only blood flow could provide. The heart can only beat against so much pressure before it losses the battle. Rookies couldn't hope to withstand more than about 5 or 6 g before losing consciousness.

Answer 2

A2. Please ignore the rubbish below.

In the US Air Force, Col John Paul Stapp withstood up to 46 G in a specially designed chair mounted on a sled. Over a period of years, he pushed the G limit upwards, and made great improvements to harness, and seating position. He suffered many injuries in the course of these explorations, and permanently damaged his eyesight. Prior to his experiments, 18 G had been the accepted upper limit.

The answer to the question "how many G's can kill a human" cannot be denoted by a single integer under every circumstance. The number of G's that can kill a human is inversely relative to the diameter/speed/length of the weapons they yield. To compound on the variables of this perplexing equation we must also take into count the validity of the G's in question. If they are real O.G.'s the Damage Per Second (DPS) would be thrice that of a non-O.G. Whence calculating this we must also set time parameters, denoted as such {0

XG=[(d L)DPS]/(ts-tf)

Answer 3

That would also depend on the time, the direction, and the posture. You can withstand a larger acceleration for a short time, or a shorter acceleration for a longer time. From the Wikipedia article con "g-force": "A hard slap on the face may briefly impose hundreds of g locally but not produce any real damage; a constant 16 g for a minute, however, may be deadly."

Answer 4

The maximum G-force a human can endure without risk of injury or death varies depending on the duration of exposure. Short durations of up to 5 Gs are generally safe for most people, whereas sustained G-forces above 9 Gs can be potentially fatal without proper training and equipment. Astronauts and fighter pilots are trained to withstand higher G-forces through specialized techniques and equipment.
