After entering Donghuang No. 2, Lin Dong went directly to the cockpit, he did not take off immediately, but started the control computer to test the entire body and various systems again. Pen ~ fun ~ pavilion www.biquge.info

It took about ten minutes and the test was still normal.

This time, Lin Dong was a little relieved.

Don't look at the insistence on coming up just now, and I came up alone, I really came up, and it was impossible to say in my heart that I wasn't nervous.

After all, this trip is to go to outer space, flying in the sky! This kind of trip is not to mention domestic, even if it is abroad, it must be after ten or eight trips of experiments, and then we will consider whether it is okay for people to go up.

Don't look at the old American space shuttles bombed one after another, that is after how many successful flights people have experienced, they have entered the retirement period!

This should be placed in the country, in the country's aerospace group, who dares to fly so casually twice and put people on it, it will definitely be criticized! It's a trivial matter to be criticized, and it's hard to get rid of the black gauze hat!

Over the years, Huaxia has hardly had a single aerospace accident, and it has been successful every time, that is after a lot of advance preparation, and sophisticated testing and verification.

Lin Dong himself is actually a little nervous, although everything is detected normally, and the cold data given by the computer can't deceive people, but after all, he is in the sky, who can guarantee that the sheep will be fine when he goes up, and he will be fine if he goes up?

But the urgent desire in his heart still made him decide that he must fly like this!

After checking the rescue capsule under his feet again, whether it was an automatic ejection device or a manual ejection device, there was no problem, and Lin Dong started Donghuang No. 2 at this time.

The people waiting outside were actually a little anxious.

I've been waiting for more than ten minutes, can I fly or not?

Lin Dong sat in the driver's seat and started, although he was rich in theory and knew Donghuang No. 2 well, but if he really wanted to talk about driving this thing, it was still a new ding.

However, now was the perfect time to practice, and he didn't want to learn the familiarization process in the air after taking off on autopilot, so he pressed the buttons one by one, and then controlled the pilot's instrument and began to take off.

The engine output slowly increased, and Donghuang No. 2 trembled slightly, but it did not rise yet.

"Xiao Xu, do you want to contact Xiao Lin, are there any other questions in it? Now this situation ...... "Even Qin Xiangjie is a little uneasy."

"Don't worry, don't worry!" Xu Xiaofeng is the most knowledgeable about the situation, and he explained with a smile: "After Mr. Lin goes up, he must check the body again, which will take more time. We watched it twice before, it was autopilot, and all the programs were in the computer, so it was relatively smooth. Now Mr. Lin should be preparing to drive manually, so the whole process should be slower - after all, it is the first time for him, although the procedures are clear, but that is theoretical, and the actual operation may have to have a gradual process. ”

After his explanation, everyone understood. The technicians were no longer restless and continued to watch.

Xu Xiaofeng himself was also thinking, wait for Lin Dong to go up for a while, and then come down, I am afraid that he will have to go through such a process - will he wait for these technicians to leave, and then secretly take off into the air? Otherwise, isn't it annoying that so many people are watching from the outside, and there is no way to rise up immediately?

He didn't know at all that Lin Dong didn't plan to let him take over in the short term......

As the engine power increased, the body of Donghuang 2 finally left the ground, but it was not as smooth as the previous two liftoffs - the previous action, just like those landing ship actions in the sci-fi blockbuster, first slowly balanced into the air, after rising to a certain height, "brushed", and accelerated into the distance.

Now, it staggered up, and it hadn't risen to more than a hundred meters, maybe Lin Dong couldn't help it, or for other reasons, the body no longer rose directly, but began to fly in the southeast direction while rising......

In general, the liftoff is normal, this dry technician understands the shaking, especially after the speed is accelerated, and the shaking is not felt at all, just look at the arrow that is like a string of arrows directly out of the line, and then there is no shadow, the operation of people can have such a fast speed, except for one or two people who are worried about whether it will get out of control, others said that it is okay.

"Is it possible to overload at such a fast speed?" A technician asked this question.

Overloading has always been a problem for pilots, especially fighter pilots.

Generally, when the aircraft flies at a constant horizontal speed, the acceleration of the aircraft is equal to the acceleration of gravity, which is a G, and when the aircraft performs variable speed flight (acceleration, deceleration, turning, diving) and so on, the acceleration of the aircraft is greater or less than the gravitational acceleration. The overload is equal to several times the gravity, which is generally called several Gs, for example, when accelerating the flight, its acceleration exceeds the gravity by eight times, and there is an overload of eight Gs.

Of course, this refers to the overload of the airframe, and the overload of the pilot is another concept. Because if it is only a single action, then the overload of the airframe is the same as the overload of the pilot, but if the airframe is momentarily circling, the pilot moves in a circle with the aircraft, and the other direction moves in a circular motion around the center of gravity of the aircraft, and the overload is the addition of the two.

With the physique of an ordinary human, an overload of 10G will be unconscious in less than 10 seconds, and even a pilot will have black vision when he is overloaded beyond his or her own ability. If there is no anti-load suit, 5-6 G's will not be able to stand it, and the current overload of 9 G's is basically the limit.

However, the above speaks of airplanes.

In fact, the overload of the spacecraft is much stronger than that of the flight -- so astronauts usually have to wear spacesuits, and a big part of this is to resist load.

The principle of anti-load clothing is that when the flight overload is generated, the air pump inflates the flight anti-load suit, compresses the blood vessels and makes them unable to flow, restricts the large amount of blood flow out or inflow, and reduces the reaction of "black vision" or "red vision" to ensure flight safety. This type of inflation is mostly inflate the limbs and abdomen.

At best, the overload of an airplane is less than 10 G, but it is normal for space flight to reach more than 10 G, otherwise it will not be able to reach the cosmic speed and will not be able to fly into space.

And the Donghuang No. 2 that Lin Dong is riding, its speed really has to add up, and the overload will be even greater, not to mention a dozen G's, hundreds of G's are possible, otherwise it is impossible to reach the moon in a short time - then the question is, how can Lin Dong resist it?

If you can't resist the past, do you have to learn from Chang'e-1 and fly slowly?

Can't stand it? (To be continued.) )
