Chapter 594 The Fantasy of the Moon Base

The aerospace plane is an aircraft that can freely shuttle between the atmosphere and space, and is one of the important development directions for future space exploration and aviation transportation.

The current technical solutions of various countries are that the aircraft and the spacecraft are separated, not integrated, that is, the aircraft sends the spacecraft (rocket) to high altitude, and then the two are separated, the aircraft returns to the ground, and the spacecraft continues to take off into space .

Mu Yang thinks that this technical solution is too troublesome, and it is not as convenient as the Xingkong-1 rocket.

Of course, this kind of separation is also beneficial. The spacecraft does not have the burden of an airplane, and there is much less resistance. It is easier and safer to fly into space.

It's not that they haven't thought about the integrated type, but the integrated type has too high requirements for the engine, and only the Xinghai Group's rocket engine has too much thrust, so there is no need to worry too much about the structure and load.

Therefore, the aerospace aircraft developed by Xinghai Group is integrated, and the power scheme is a rocket engine + two afterburning turbofan engines.

Since Xinghai Group's rocket engine fine-tuning control is very good, it is also possible to use only one rocket engine design, but it is not so flexible. As long as the afterburning turbofan engine with vectoring nozzle is installed, it is easier to control the direction.

The aerospace plane is already a special item of the system. It needs to have basic aviation technologies such as supersonic aircraft and rocket launch, and cannot be purchased directly.

At the end of last year, when Mu Yang solved the core technology of the engine, he was eligible to purchase aerospace aircraft technology.

Today, more than a year has passed since the establishment of the aerospace plane project, and the progress has been somewhat bumpy, but most of the work has been completed in the end.

It can be said that it is at a critical juncture.

Both Mu Yang and the researchers in the project team want to see the aerospace plane soar into space, and even fly to the moon.

Recently, Mu Yang has been dreaming about aerospace planes, which shows that he is looking forward to it.

Many of them are nightmares, dreaming that the aerospace plane exploded and the astronauts on it died.

He always felt that something bad was about to happen.

Mu Yang came to the laboratory and heard from the project leader that most of the components have been processed. First, the small modules are assembled at the headquarters base, and then these small modules are transported to the rocket base for the next step of large assembly.

The rocket base has been expanded in the past year. Two heavy-duty runways with a length of several kilometers can withstand the landing and lifting of several thousand tons of aircraft. The PCN value (carrying capacity index) and CBR value (carrying ratio) , FOD value (foreign object hazard index) and brake index have strict requirements.

So far, the company has undertaken and completed 28 rocket and satellite launch orders this year, launching more than 100 satellites in total, with a 100% launch success rate, contributing a billion dollars in revenue to Xinghai Group.

Rocket launch revenue is of little importance to rocket bases, and the bulk is still in Starnet. At present, 400 million people around the world are using Starnet’s broadband and mobile phone networks, creating about 300 billion yuan in revenue for the company, and has achieved profitability. , but also huge profits.

Correspondingly, the employee benefits of the rocket base are also very good. Working in the rocket base, the working environment is relatively boring, which is equivalent to an extra business trip expense.

As graduates who have just come to Xinghai Group, when they become full-time trainees, they are very much looking forward to which department they will be assigned to.

The more difficult the place, the subsidy must be more. For example, the desert greening base has not yet produced benefits, and it has a different system from the headquarters base. It is an independent company and receives less income than the headquarters base.

But for most graduates, the remote department of Xinghai Group is also the place where graduates dream of working.

Mu Yang patrolled around the Aerospace Aircraft Laboratory, asked about the progress of the project, and then returned to his office.

After sitting down, sip tea slowly, and take a look at your achievement points.

Since buying aerospace technology last year, he hasn't consumed any achievement points this year. Only last night, the system counted his achievement points. The total achievement points rose from 4396 points to 7206 points, officially breaking through 5000 points.

The main growth points are technology authorizations such as high-level high-speed rail, rocket technology, rocket design, communication satellite-Xingye 1, ground-effect aircraft, computer operating system, and lift fans. The submitted technologies are all non-core technologies.

With more achievement points, he has a new plan.

He didn't open the second direction of [Biomedicine], which requires 5000 achievement points.

The main reason is that in the next year, he will need to spend a lot of achievement points, estimated to be more than 2,000 points. If he spends 5,000 achievement points to open the second direction, he will need to spend a lot of achievement points to buy related technologies. If it is not enough, it will affect his scientific research plan.

The time interval for the reading system to count achievement points is getting longer and longer. It used to be half a year, but now it takes almost a year to count.

Although the second direction of biomedicine has not been opened, Mu Yang has determined that the second direction is [Human Genes - Physical Fitness].

He doesn't know how much physical fitness can achieve. Mu Yang still hopes to provide assistance for future interstellar travel, such as on high-oxygen or low-oxygen planets. By optimizing human genes, humans can quickly adapt to the new environment.

For example, long-term space travel, human beings can resist muscle atrophy, osteoporosis and other problems in the absence of gravity, instead of relying on exercise or some gravity equipment to adapt.

Mu Yang was thinking, Yang Hai, vice president of the company, came in to report some work to him.

After the report, Yang Hai talked about an interesting thing: "Chairman, there are many single nobles who want us to study robots for beautiful women or robots for handsome men." After speaking, he himself couldn't help laughing.

Mu Yang frowned, but didn't turn his mind all of a sudden: "What do you mean?"

"Uh, I just want to find a friend of the opposite sex who thinks differently."

"These people have a clear mind. Although our technology can do it, we can't do it. It will ruin the atmosphere. Anyway, it can't harm the people of the country."

"Chairman, we definitely can't produce by ourselves. If we secretly authorize the company of the island country and only sell it to the people of the island country, earn money from the other party, and cheat this country, it seems that it is not impossible." After Yang Hai finished speaking , smiled badly.

Seeing his expression, Mu Yang couldn't help laughing, but he was worried: "There is no impenetrable wall in the world, can you guarantee that it will not be exposed?"

"Of course there is no guarantee that the secrets will not be leaked. It is fine if we don't admit it. The market in that country is quite large in this regard.

As long as the quality is good, it is realistic enough!

Cough cough cough, for them, as long as the expression is realistic enough, it is estimated that there are millions of them in the market, and if it sells for more than 100,000 yuan, it will be a market of nearly 100 billion yuan. "

Mu Yang rolled his eyes at him: "Well, for hundreds of thousands of dollars, in that country, it seems to be much easier than getting married.

All right, you go to Wang Hai, I don't know about this, anyway, don't get involved with the company.

If it makes money, the company will take half of the profit, and the rest can be distributed in any way. "

"Well, we will find a suitable agent. If it is really exposed, it can be said that the company's technology has been leaked and used by them, and then the two parties will settle, and the other party will compensate part of the profits to the company."

"It's up to you, don't tell me these crooked ways." Mu Yang waved him to get out.

Yang Hai smiled, knowing that the chairman agreed, and he was very happy, but on the surface he didn't want to touch it because of his status.

He bowed slightly, and then exited the chairman's office.

Half an hour later, Wang Hai, the vice president of technology, came to ask Mu Yang.

"Chairman, Mr. Yang said that he wants to authorize some technology to the agency company in the island country to make smart robots with beautiful and handsome men. I want to check whether there is such a thing."

"Well, I told me, and I agreed, but this kind of thing, if I don't know, you can do it according to your needs, just keep the technology secret, and don't get involved with the company." Mu Yang raised his head and replied solemnly.

It was right for Wang Hai to ask him, and he didn't know if Yang Hai had any selfish intentions.

"Okay, then I understand." Wang Hai nodded and exited the chairman's office.

Seeing Wang Hai leaving, Mu Yang couldn't help laughing in the office.

If the population of the island country is greatly reduced, the Xinghai Group will definitely have a contribution.

Abandoning these distracting thoughts, Mu Yang calmed down and thought about the construction of the moon base.

Building a foundation on the moon is not for mining, but for interstellar development.

If it is not even possible to build a base on the moon, then it is impossible to build a base on other planets.

It is very difficult to build a base on the moon, mainly because of the extremely large temperature difference.

The highest temperature depends on the sunshine and terrain, usually it can reach about 127°C in the sunlight during the day, and it may drop to -173°C or even lower at night.

If you have studied material science at this low temperature, you will understand that if you build a base on it, the optical materials will be limited.

For example, the use of general steel is prone to brittle fracture, or the performance is greatly reduced.

Therefore, all steel materials that can withstand force can only be low-temperature materials, and ordinary carbon steel will not work.

"This temperature difference is too much of a headache!"

The temperature difference on the space station is also large. The highest and lowest temperatures in Earth's near-Earth orbit depend on many factors, such as sunshine time, the Earth's atmosphere, solar activity, and so on.

Generally speaking, in the Earth's low-Earth orbit, the highest temperature can reach about 121 degrees Celsius, and the lowest temperature is about -157 degrees Celsius. These temperatures were measured without any covering or protection.

However, it takes about 90 minutes for the space station to circle the Earth, or about 87.6 minutes per orbit to be precise.

This means that it orbits the Earth 15.7 times a day, or about 28,000 kilometers per hour, and orbits at a speed of about 28,000 kilometers per hour.

The orbital height of the Halo space station is about 420 kilometers, and it needs to move around the earth at high speed to maintain the stability and speed in orbit.

Although it has a large temperature difference, the alternation of hot and cold is very frequent. In reality, the temperature is much less.

When the temperature is the highest, it is the frontal radiation of the solar storm at that time, and it is also the most dangerous time.

Therefore, if you are active outside the space station, if the solar storm or the cosmic storm is the most intense, it is best not to do extravehicular activities.

Even if the extravehicular spacesuit can resist, what if there is danger.

On the moon, the situation is different from the space station, and it is completely different from the situation on the earth.

This is different, it is the long days and nights on the moon!

Since the moon's rotation period is consistent with its revolution period, a lunar day is 27.3 Earth days, so each moon's day and night last for about two weeks.

Two weeks!

This time period is too long.

Not to mention the moon, if the earth is at night for two weeks, just like the north and south poles, the temperature is very low.

Anyway, the North and South Poles can still be irradiated by the sun, and the lowest temperature is tens of degrees below zero.

The moon is not illuminated by the sun, and the moon has no atmosphere, and there is no mechanism similar to the convection and radiation on the earth to transfer heat.

Unlike Earth's atmosphere, which absorbs heat from the ground and dissipates it into the air, maintaining a relatively constant temperature.

On the surface of the moon, without such a mechanism, the heat would be lost quickly.

Therefore, when the sun goes down, the surface of the moon will quickly lose heat.

Since there is no atmosphere, heat cannot be retained, resulting in a sharp drop in the nighttime temperature of the lunar surface. In addition, there is no moisture on the lunar surface, so there are no processes such as evaporation and condensation, which also means that the ability to absorb and release heat is weak.

Therefore, no atmosphere, long nights, and lack of moisture are the three important reasons why the surface temperature of the moon can drop to minus one or two hundred degrees Celsius.

Similarly, it is also the reason why the temperature can rise to more than 100 degrees Celsius.

What gave Mu Yang a headache was the large temperature difference, not the lack of oxygen and gravity.

Of course, if the base is built underground, the temperature difference will definitely be much smaller.

However, human beings have to come out to carry out activities and experiments.

Therefore, the more suitable time to come out for activities is the first half of the time after the sun sets, when the temperature is not low enough.

But when the sun rises, although the surface temperature is very low, the light radiation is very large, and it is no longer suitable for coming out.

If the Xinghai Group wants to land on the moon, it is best to land on the far side of the moon, where the sun has just landed not long ago.

As for all kinds of robots, they must be able to withstand complex conditions such as high and low temperatures, regardless of temperature differences.

The equipment is in a high temperature condition for a long time, for Muyang, it does not worry, it can use the solar energy to drive and cool down.

But in the low temperature condition for a long time, it can only use the energy stored in itself to drive equipment and heat. If there is no energy, it will be a headache.

In any case, neither situation is so easy to solve.

"Hey, there is too much work to do to build a moon base!"

Mu Yang patted his head, feeling a little headache.

If his ideas are known to all countries, they will know that his ideas are too crazy.

The construction of moon bases by various countries is just a fantasy.

As for Mu Yang, he just wants to do it now, not just think about it.

I don't know how long it took, but Mu Yang's thoughts became clear.

The first step must be to land on the moon, obtain information on the moon, and find a suitable place to build a base;

The second step is to choose and build some base modules on the earth, and after they are built, they will be transported to the moon by aerospace aircraft.

At the same time, all kinds of intelligent robots are developed on the earth, such as mining, gravel, paving, construction and so on.

The cost of transporting modules from the earth is still too high. If you want to build a large base, you still need to rely on these intelligent robots.

In the third step, after the base module is transported to the moon, these intelligent robots are ordered to start digging underground holes.

The first base of the Xinghai Group is best built underground, and when the conditions are ripe, it will slowly develop to the ground.

After completing the above three steps, and subdividing them further, Mu Yang found that there is a lot of work to be done.

The intelligent robot currently developed by the company is not intelligent enough to operate automatically on the moon.

In addition, the robot needs to be well protected against high temperature and low temperature, and needs to be redesigned, and the structure is much more complicated.

Generally speaking, there is still a long way to go to build a lunar base, but at least we have a foundation.

After Mu Yang cleared his mind, he didn't think about it today.

An acquaintance once asked him why the Xinghai Group's goal was the stars and the sea.

Mu Yang is sometimes vague about this goal, but his heart is very strong, as if the system is guiding him.

From another perspective, if he doesn't do it, it is estimated that it will be difficult for human beings to make major breakthroughs in space development within a hundred years.

Since he has the ability, he should be a pioneer. He is also very curious and has a strong yearning for interstellar travel.
