"Red is the true center of gravity, and you can't determine until you spin it...... Heck, you all know you don't need me to talk about it. ”

"Don't don't, you go on, go on."

Although Ye Changsi is not a few years older than Shen Zuozhou, the latter respects him very much, because Ye Changsi is the only god who can talk to the transcendent madmen of the High Energy Institute, and he is definitely the top stream in the aerospace industry.

"Then I'll go ahead...... Ahem, when the entire space station rotates to determine the true center of gravity, as long as the error is not too large, it can be handed over to the AI.

There are two main solutions to the problem of the difference in the center of gravity:

The first is the real-time control of the rotating attitude adjustment device, which can be adjusted by ion thruster and gas RCS in different situations, as long as the adjustment range does not allow the space station to tilt significantly, and the small attitude imbalance and yaw do not need to be ignored, and then actively adjust when the accumulation reaches a certain level.

The second is the gravity slip ring that we place in the hollow area of the spoke cabin, the functional cabin and the pilot cabin, and half of the mass of the 30-ton spoke cabin is this gravity adjustment system.

Through the displacement of the high-density metal slip ring, the axial and longitudinal centroid of the entire space station is automatically balanced, and it is also the most important stabilizing device.

It is the most sophisticated part of the space station outside of the power system, requiring a separate emergency power supply and frequent inspections, as well as avoiding any major impacts and damage.

Generally speaking, as long as one of these two systems is working properly, it will definitely restore the space station to a stable state, and Progress itself does not have the ability to repair them independently, even if we send the space shuttle to repair it, it will be very difficult. ”

After Ye Changsi finished speaking, he paused again, looked at Zhong Cheng, who didn't know when it would come, and Lin Ju, who was listening with great interest, and Lin Ju, who yawned, and said:

"Repairs to any of the station's modules are so complex that they might as well be replaced, costing hours and risks.

Our next phase should be to build a new semi-open space port of more than 1,000 tons to provide maintenance capabilities for large space facilities. ”

Jong-sung, who was still immersed in technical details, immediately came to his senses, and now he is very sensitive to anything budget-related.

"Can't we renovate based on the existing facilities, adjust the configuration of the Tiangong space station, and add a few special modules, which should also accommodate the Qianjian, right?"

"Of course not, the configuration of the Tiangong space station has basically reached the upper limit, even if it is basically feasible, we have to consider the maintenance of a larger space station or spacecraft in the future."

"Bigger?!"

Zhong Cheng regretted why he came here after a lengthy discussion on deep space exploration, and immediately stepped aside.

Lin Ju didn't notice the confrontation between the two because he was tired, and now he just wanted to go to the hotel to get a bottle of "Anshenduo" and get a good night's sleep.

314 injections have been officially in the clinical trial process, the official name is "tranquilizer", which has been improved from injection to oral liquid, and has been forcibly classified as a second-class psychotropic controlled drug by the Pharmaceutical Bureau, which is the same level as sleeping pills.

The biological laboratory first wanted to sell "Anshenduo" in the category of health care products, promoting it like a functional drink, but after observing several clinical trials in the Pharmaceutical Bureau, it did not hesitate to refuse, even if Xinyuan is strong, it can only be a psychotropic drug.

The description of the efficacy is also very peculiar: the effect of this product is to provide 10 to 12 hours of high-quality sleep without damage, and after taking it for 5 minutes, it will produce 1 to 2 hours of hyperactivity, and there are no obvious side effects, no more than four times a week, and overdose has aggravated insomnia and other risks.

Instead, the side effects of the 314 injection became the main potency, and the drug was adjusted to increase the frequency of use, because the pharmaceutical bureau refused to publicly sell any "stimulant" drugs, no matter how reliable, but was willing to use them instead of sleeping pills.

The consequence of excessive use of "tranquilizer" is to cause varying degrees of vomiting, diarrhea, fainting in severe cases, or temporary reduction of immunity, but it is not as dangerous as ordinary sleeping pills.

However, "Anshenduo" has successfully attracted the attention of the army, and it seems that there is a plan to include it in military supplies, after all, this thing can replace morphine to a certain extent, and the side effects are far less great.

"Anshenduo" has now circulated within the base and in a small area of the Aviation Development Commission, especially when the spirit is not good but it is needed, a bottle of energy that makes people dream back to the age of eighteen.

Through the promotion of the base, "Anshenduo" can almost start circulating in November, but because of the control of Class II psychotropic drugs, Lin Ju is pessimistic about its sales prospects.

While he was thinking about "calming the nerves", Ye Changsi had already completed the inspection of the preparations for the Advance.

It's 26 p.m. on February 26 and everything is ready.

Lin Ju was poked back to reality by Zhong Cheng at this time, and then nodded to Ye Changsi with great trust:

"Let's get started, let NACA see what the world's second working artificial gravity device looks like."

……

Forward.

In the pilot module on the axis, the console that Li Sheng used to operate often lights up, and the SC09 intelligent AI of the flight computer activates the gravity function module, which is connected to each sensor and power unit through wires and fiber optic cables.

The attitude adjustment vents on the 12 centrifugal modules began to work, first adjusting their relative orientation to the Earth, as the previous "Isaac Newton" did.

However, unlike Isaac Newton, the Advance's central axis of rotation is in the same direction as the line to the center of the Earth, and the front of the ring can still be seen from the Earth.

The process took only 30 minutes, as the Advance had been roughly aligned for months of testing, and now it was just a matter of fine-tuning and confirmation.

After the completion of this work, nearly a hundred independently controllable RCS on 12 compartments began to eject gas in a unified tangential direction.

The nearly 1,700-ton space station does not look heavy in space, and the RCS power is very low, but it still steadily pushes the entire space station to start slowly rotating.

The goal of the first test run was 0.2 revolutions per minute, that is, only one revolution every five minutes, which is a very low speed.

But this was enough, and at a speed of more than 0.05r/min, the sensors inside and outside the Advance had already captured the uneven center of gravity of each part, and the metal slip rings of the six spoke compartments began to move outward to varying degrees, so that the three-dimensional position of the red dots on the display and the green dots coincided as much as possible.

It's a rather complex process to design to the entire space station, but it's already going on in sync when the RCS is working, and the actual time is much shorter than people think.

After only 20 minutes, the Advance had reached its expected speed of 0.2 revolutions per minute, and the outermost centrifugal chamber was moving at a speed of 1.3 m/s, gently brushing through the empty space.
