Daming 1805

Chapter 494 "Fake Moon" Project and Rocket Launch Base Site Selection
The people below Shaofu Ruan Yuan and related personnel of Qin Tianjian subconsciously wanted to open Zhu Jingyuan's files to check.

Hearing what Zhu Jingyuan said behind him, they all stopped immediately.

Put Zhu Jingyuan's documents in front of him, and concentrate on listening to Zhu Jingyuan's other project arrangements.

Some people were very curious. What did Zhu Jingyuan want to do when the people from the Qin Tianjian, the Ministry of Industry, and the Ordnance Department were gathered together?
However, some people already have guesses in their minds, because these three departments have cooperated in the first place.

As long as you understand the content of the previous cooperation, and then change the method of cooperation from the Ordnance Department to the Qin Tianjian, you can probably guess what you are going to do.

Zhu Jingyuan's eyes swept over the eyes of the people on the scene, and he slowly expressed his vision of the goal:
"I want to arrange for people to go to space to see, even to the moon.

"This is of course a long-term goal, which is expected to be completed in the next 30 years.

"The idea of ​​our immediate first step is to try to send radio communication equipment into space.

"According to the logic of astronomy, when an object flies fast enough, it can leave the ground forever.

"It can fly out of the atmosphere and orbit the earth like the moon.

"If this thing has radio communication capabilities, it can provide ultra-long-range communication relay for the ground.

"The simple idea to achieve this goal is to use guided rockets developed by the Ordnance Department.

"Make the rocket big enough to replace the warhead with a communications device.

"The idea is simple, but the difficulty lies in how to actually realize it."

When Zhu Jingyuan's idea was mentioned, the irrelevant personnel were shocked.

But most of the people in Qin Tianjian couldn't help being excited.

Because that's the plan many of them had envisioned.

It just hasn't gotten enough support yet, and hasn't had a chance to really try it yet.

After the Renwu Dynasty, the Qin Tianjian of Daming became more practical.

The work is clearly directed to the research of astronomy, calendar, meteorology and so on.

In terms of specific practical work, they are actually much more valued than before.

Qin Tianjian is the chief official. Before the Renwu Dynasty, he was only the fifth rank, which is equivalent to the chief official of the Qingli Department under the Six Ministries.

Later, he was gradually promoted to the Shangshu rank of the second rank by Emperor Shizu.

However, the traditional symbolic meanings they originally carried, such as good and bad luck, were quickly stripped away.

That is to say, the sense of mystery gradually disappeared, and it became a relatively objective research institution.

The official position of Qin Tianjian is also mainly promoted internally, because this institution is too professional.

The personnel of Qin Tianjian are even more inclined to pure scientific researchers than those of the Ministry of Industry and the Ministry of Ordnance.

In addition to the officials in charge of specific affairs such as the principal and deputy of the Qintianjian, there are also a large number of full-time "Qintian officials" who enjoy different levels of treatment in the Qintianjian.

They are the de facto astronomy researchers supported by the imperial court.

The highest level can even surpass the second-rank Qin Tianjian Zheng, and can directly reach the benefits of the first-rank Zheng.

The Ministry of Industry, the Ministry of Ordnance, and the Ministry of Construction also have similar craftsmen inside.

They are scientists and engineers who enjoy the treatment of state officials.

Therefore, it is difficult for the personnel of Qin Tianjian and Sikong system to communicate with officials of other departments.

Emperor Shizu also sought to avoid laymen leading experts as much as possible, so these departments have the most internal promotions.

Fortunately, they were all departments that the Emperor Ming paid close attention to, and the inner circle was constantly being broken up and reshaped.

At present, there is no general group similar to Xuefan.

Qi Yanhuai, deputy of Qin Tianjian, couldn't control his emotions at this time, and directly expressed his thoughts:

"Your Majesty is going to have a holiday!"

The word satellite appeared very early, but like many ancient words, it is a phrase composed of two single-character words.

It means a secondary star that guards a primary star, and is usually used to describe the relationship between stars.

These two words have not been specialized into the name of a specific thing.

In Zhu Jingyuan's previous life, the word "satellite" became specialized to mean a secondary planet orbiting a planet. This occurred in the era when modern Western astronomy began to influence Chinese astronomy. Translators used this word to define a specific type of planet.

In this world, some astronomical knowledge brought by Emperor Shizu strongly influenced the development of astronomy.

Ming astronomers discovered small stars orbiting Jupiter through telescopes.

These stars are likely to be defined as satellites, corresponding to the meaning of the secondary planets of the original satellite main star.

However, Emperor Shizu led them to verify the theory of heliocentric theory, making them believe that these secondary planets are actually the same as the moon.

Both are secondary planets orbiting a single star.

Ever since, these secondary planets were also treated as moons.

They'll just say "Jupiter's moons", Jupiter [-], Jupiter [-]...marked like this...

So far, the phrase "satellite" still largely retains its original meaning, a general term relative to the main star.

In the solar system, the sun is the main star, and the gold, wood, water, fire, and earth surrounding the sun are all satellites.

In the Jupiter system, Jupiter is the main star, and its moons are all satellites.

At the same time, the concept corresponding to the artificial satellites of later generations has also been formed in the research institute of Qin Tianjian.

The word is "false moon".

The fake here refers to the fake of rockery and wig, which means artificial, not natural.

Some Qintian officials have already calculated that the idea of ​​a false moon is achievable, and the key depends on the efficiency of the rocket.

More importantly, is the imperial court willing to spend money to fund the completion of this project.

Zhu Jingyuan came to this meeting today for this purpose.

Zhu Jingyuan didn't mind Qi Yanhuai's sudden interruption when he heard what Qi Yanhuai said, but directly issued an imperial edict on the spot:

"The purpose is to officially launch the holiday moon project.

"The three departments of Qin Tianjian, the Ministry of Ordnance, and the Ministry of Industry are jointly responsible.

"Qin Tianjian is in charge of the fundamental research of the entire aerospace engineering that puts the fake moon into orbit.

"The Ordnance Department is responsible for the design of the rocket itself, which will also be used in the development of weapons in the future.

"The Ministry of Industry is responsible for the functional design of the holiday itself, and provides engineering and technical support for the other two departments.

"The application for the funds required for the project will be sent to me for personal approval, and the progress of the project will be reported at any time.

"The director of the False Moon Project is Shaofu Ruanyuan, and Sikong Liu Wei is the deputy.

"Qin Tianjian, the Ministry of Industry, and the Ministry of Ordnance cooperate with each other, and there must be no mistakes."

Zhu Jingyuan ordered directly on the spot, and the accompanying university scholar Niu Jian made the imperial decree on the spot.

All the officials stood up immediately and bowed very seriously:

"The ministers obey the order."

Zhu Jingyuan paused for a moment, asked them to sit down, and continued to arrange some details.

The main craftsmen were asked for their ideas and opinions on the spot, mainly to express their importance.

At the same time, there are indeed some things on the scene that need to be decided as soon as possible.

For example, the launch site.

Qi Yanhuai himself has specialized in the study of the False Moon Project, so the possible situations involved in this project have already been considered and analyzed many times.

Therefore, based on my own vision, the scene first expressed my opinion on the selection of the launch site:

"Your Majesty, I and a few colleagues have done a calculation to deploy a fake moon into space through rockets.

"It was found that if the direction and inertia of the earth's rotation are considered, the actual energy required for the rocket to deploy the false moon into space will be affected by the latitude of the launch site.

"For a false moon that uses a similar geosynchronous orbit, relatively close to the equator's transverse orbit, and runs from west to east.

"With the same weight of the false moon itself and the same altitude of the target orbit.

"The closer the launch site is to the equator, the less energy is required to launch.

"The closer the launch site is to the pole, the more energy is required to launch.

"With a sun-synchronous orbit, which is a false moon moving north-south, the situation is reversed again.

"The closer the launch site is to the pole, the smaller the energy required for launch, and the closer the site is to the equator, the greater the energy required for launch.

"During the development and testing of the rocket, it is necessary to conduct experiments many times.

"So for launch and experiment sites, it is best to start site selection in advance and complete the basic construction as soon as possible."

Qi Yanhuai's explanation was rough, but Zhu Jingyuan immediately understood what he meant.

Although Zhu Jingyuan was not a person majoring in aerospace engineering in his previous life, he was a young man yearning for the stars and the sea.

I have paid attention to the news and introductions of aerospace, and have the most basic understanding of the common sense of rocket and satellite launches.

In the previous life, the rocket launch bases of the major aerospace powers on the earth were basically selected as low as possible in latitudes.

Because the earth is constantly rotating, and the closer to the equator, the greater the linear velocity of the earth's surface.

Therefore, the closer the rocket launch site is to the equator, the more the earth's rotation inertia can be used to help "throw" the rocket out a little bit.

In this way, a little fuel can be saved, and the weight of the equipment sent to the sky can be slightly increased.

If you do not consider external conditions such as infrastructure, political influence, confidentiality conditions, and security measures.

Simply considering the environmental conditions, the most ideal rocket launch base should be on the west coast of the ocean near the equator.

After the rocket takes off, it flies from west to east. If there is an accident, it will directly fall into the sea, and will not threaten the people on land.

The best place is sunny and rainless, the air temperature is stable and dry, and the coastal plateau is flat.

This is conducive to the storage and work of the rocket itself and fuel.

There is no place on the entire planet where these ideal conditions are all met.

The relatively perfect place is the eastern part of the Mozhou mainland, and the northeast part of Zhu Jingyuan's own Huangzhuang.

The local temperature is a bit hot, and there is still a four-month rainy season, which is not dry enough.

However, considering those other factors, the final practical choice is usually full of compromises.

For example, China's early satellite bases were basically in the inland Northwest China.

Because during the period of developing aerospace engineering, the international environment in foreign countries was extremely harsh.

Both the navy and the air force are relatively weak and cannot effectively control the southeast ocean at all.

If the rocket falls, it may be picked up by the hostile navy.

For the sake of safety and confidentiality, let the rocket take off in the early stages, try to keep it in the air above its homeland.

So I can't use the southeast coast of my own homeland, let alone the east coast of Mozhou, which is far away in the sky.

Later, the external environment improved, and our own navy and air force also had certain strengths.

A new rocket launch base was built in Qiongzhou, the southernmost state in the mainland.

However, in this world, the current situation of Daming cannot be said to be good, it can only be said to be completely overturned.

The entire Daming Ocean and Little Western Ocean can basically be regarded as the inland sea of ​​Daming.

Although the east coast of Mozhou can't be regarded as the mainland, it is the Huangzhuang directly controlled by the emperor Zhu Jingyuan.

Zhu Jingyuan recalled the situation in his previous life and compared it with the reality, his heart was full of emotion.

Then he casually took over Qi Yanhuai's words:

"So, the best launch site for launching geosynchronous orbit satellites is the coastline between Mu County (Mogadishu) and Meng County (Mombasa) in the east of Mozhou?"

Qi Yanhuai and other Qin Tian officials at the scene were a little surprised to hear Zhu Jingyuan's response.

Unexpectedly, the emperor's judgment coincided with his own point of view.

This shows that the emperor really understood and considered this matter seriously.

The emperor really understands and attaches great importance to it, which means that this matter will go very smoothly.

Qi Yanhuai nodded heavily excitedly and said:

"Your Majesty, I have carefully studied the map with several colleagues, and I think the most suitable place is the eastern part of Mozhou.

"It is near the equator, and the local infrastructure is relatively complete.

"To the east is the vast Little Atlantic Ocean, which is very convenient for rocket observation and shell ejection.

"The disadvantage is that it is far away from the mainland, and it is a little troublesome to produce rockets locally and then transport them there.

"So if a launch base is built in Dongmozhou, the best option is to put the rocket production factory here."

After hearing this, Zhu Jingyuan nodded secretly in his heart, but he didn't directly finalize the matter.

Regarding the location of the rocket factory, Zhu Jingyuan was a little hesitant.

Rockets that launch satellites and intercontinental missiles that smuggle strategic weapons are essentially a technology.

From the perspective of the Ming Emperor, this kind of factory and R&D center should be placed in the safest and most controllable place.

The best choice, one is local, and the other is Xintianfu.

So Zhu Jingyuan continued to ask Qi Yanhuai:

"Mr. Qi, if you want to put the rocket launch base and factory in the mainland of Ming Dynasty.

"Where should the best location be? Is it the Lion City? Medan? Or even Zhejiang?"

Qi Yanhuai obviously considered this issue:

"Reporting to Your Majesty, I believe that all other regions in the world are at a greater disadvantage compared to the eastern part of Mozhou.

"If the launch base and factory are to be located in the mainland, I think the three locations proposed by His Majesty have their own advantages and disadvantages.

"The Lion City is closest to the equator, and the local urban facilities are also the most complete, but there are many islands in the east of the Lion City.

"And the place is like a tropical rainforest, hot and rainy all year round.

"The east of Medan, Dongning, and Zhejiang is the Daming Ocean, and there are not a large number of islands that affect observation and shell ejection.

"Medan is the closest to the equator, but the local urban facilities are the worst, and the climate is similar to the Lion City, hot and rainy all year round.

"Moreover, although it can be said to be a native place now, it is also the most remote place in the mainland.

"Ningbo, Zhejiang, has the most complete facilities, close to the naval base, and even close to Yingtianfu, so the management and scheduling are the most convenient.

"But the local latitude is also the highest of these regions...

"Chen's suggestion is that if the base is to be located in the mainland, the relatively best choice is the Lion City.

"Although there are many islands to the east of the Lion City, most of the areas are also rainforests, and they are basically sparsely populated places..."

"
