On the earth, when the aircraft is touched downwards, when a certain speed is reached, people will lose weight, floating. This is also a way to train astronaut adapt to weight loss. Using this phenomenon, if the challenger space shuttle seat is separately sealed, it can resist the high temperature, astronauts will not die, when the space plane pends down, the speed is getting faster, the astronaut will lose weight, floating stand up. When exposed to the ground, the speed is reduced to zero, and the astronauts fall on the bille, which will not be injured. This approach can also be used for spaceship, and the civil aviation machine has failed. Civil aviation can generally do not use this approach, but also want to fly back to the ground, but when the aircraft is serious, this is also a way.
One of them a reply:
The landlord, my brain is slow, there is a problem, I want to ask. << When exposed to the ground, the speed is reduced to zero, the astronaut falls on the bilk, will not be injured, >> Is the astronaut in the falling process, is it the speed of space? (If not, he will hit the warehouse, and according to the three laws of the Newton, the first two physics class, he can only move with the space warehouse as a space warehouse, and the speed is reduced to zero Who will slow down for astronauts? Is the space cabin? Which astronauts can't give the patime. With my experience, a high-speed sports car suddenly hit the obstacle, the driver often injured because of the inertial effect. The speed of space warehouses is much faster than the speed of the car hit the trees, and I don't know how the astronauts' inertia will disappear when they touch it. As for the aircraft, there is a weight loss, I think of an elevator, the elevator suddenly decreases, and I also have a feeling of weighty. Fortunately, the elevator automatically brakes, but I still feel that I was already awkward. I think that the elevator does not brake, directly "when touching the ground, the speed is reduced to zero", I am afraid I can't tell this, I don't know if my worries are there?
