Things to reduce g force effects on astronaut (1 Viewer)

Discuss strategies that spacecraft designers can employ to ensure the survival of living occupants as well as delicate payloads?

Well one of the main problems with gforces is not the size of them (although you try and avoid that) but the length of time the astronaut experiences them for.

Hence staged rockets are normally used rather then a continuous burn. A gap in the acceleration (going from a positive to gravity) allows the body to recover before another accleration occurs.

The way living occupants are seated, is also an important consideration, having them lie down helps blood circulation by not pooling in their head or feet.

the angle at which the spacecraft enters the atmosphere during re-entry is also important: if the angle is too steep the acceleration will increase, hence increasing g forces

They jump at the last moment before crashing.

is the angle of re-entry window 5.2-7.2 degrees?

yeah it is... I think it varies slightly depending on which text book you read but they're all around those values

ah ic, cos some say 5.6 -7.6
