Someone asked: the average person can only carry one or two g acceleration due to gravity load, more than will take gold flower produce vertigo, and how can the astronauts excess load to bear? What's so special about?
"In fact we don't have any special place, can only through the devil training improve itself load force", the Chinese people's liberation army (PLA) astronauts fei junlong said great captains.
Environmental adaptation process in space, astronaut training is one of the most centrifuge, and it is also a basic skill, also is most astronaut acknowledged as one of the most painful, sitting in the cockpit crew want to repeat a variety of load resistance not only, but also judge signal problem solving.
Through high-speed centrifuges spin, let the body to adapt to the excess load acceleration. Different from ordinary people, an astronaut can bear load is usually reach 8 ~ 10 g.
"8 g is equivalent to eight times as much weight on you", said Yang liwei, deputy director of China's manned space office, every time training, facial muscles will produce deformation, tears will automatically shua shua to outflows, difficulty in breathing at the same time.
Multifarious, in short, the astronauts of the devil training, weightlessness flight or weightlessness sink training, for example, eat and wear to take off the spacesuit weightlessness environment, all kinds of operation. In addition to shock tower, skydiving, training and so on many test.

The astronauts used centrifuge general speed control turn around 70-100。The above information by www.xzkx.net, reproduced please indicate.
