At the beginning of the civil castle, the Ming God of War was a little panicked

Chapter 403 Wind Experiment
After consultation at the Imperial Hospital, Mei Chun did not hurt her internal organs.

The left forearm was fractured, the elbow was dislocated, two ribs were broken, and there was a large bruise on the cheek. Generally speaking, it was all trauma.

Only then did Zhu Qizhen feel relieved, it was very lucky that he was still alive and kicking after falling from a high altitude.

"Flying over from Nanjing, you don't want to die?"

With a guilty smile on Mei Chun's face, she said: "The student's whim shocked the holy car, and I hope the emperor will forgive me!"

"Okay, don't say anything!"

Zhu Qizhen waved his hands and said, "I'll find you a place to live, so you can rest assured, next..."

Mei Chunzheng was about to thank her, but found that the emperor stopped in mid-sentence.

He was a little confused, but he didn't know what to do.

"Wait, wait! Wynn, take care of people!"

Zhu Qizhen dropped a word and left in a hurry.

Mei Chun scratched her head, but accidentally pulled the wound on her arm, grinning her teeth in pain.

Wynn hurried forward and said, "Mr. Mei, what's the matter with you? Let's go and invite the imperial physician for you!"

"No, no!"

Mei Chun hurriedly waved her hand as a signal, and then asked, "Excuse me, father-in-law, what does the emperor mean by...?"

Wynn shook his head helplessly and said, "our family doesn't know either."

After about a cup of tea, Zhu Qizhen dragged Beilin and hurried over.

"That's the man!"

Zhu Qizhen pointed out his hand, and Beilin stepped forward with a face full of curiosity, and asked, "Can the Kongming Lantern really carry people?"

Mei Chun nodded dully, and just about to reply, Belin asked impatiently: "How to control the altitude and flight direction?"

"This one……"

Mei Chun hesitated for a moment, and then said: "Actually, it is to magnify the folk Kongming lantern ten times, heat it with lamp oil, and then it can go up, and it can be turned off when it needs to land. As for the direction... the students don't know how to control it for the time being. It depends on the wind direction. However, the wind direction at high altitude is very different from that on the ground, and the airflow is flying back and forth, so it depends on luck where you fly."

Belin asked again: "What material did you use?"

"The top is cowhide, and the bottom is rattan."

"Is the production process difficult?"

"It's not difficult... hiss!"

Mei Chun slowly shook her head, but she couldn't help grinning because of a wound on her neck.

"...The cowhide needs to be made of high-quality materials, and the joints should be sewn tightly, and the rest is fine."

Belin turned around and said, "Your Majesty, it is possible!"

Zhu Qizhen nodded and said: "It's not too late, let's set up the Kongming Lantern Research Institute immediately, and make a batch of samples first to see how it works."

"Yes!"

Belin turned and left, walked to the door and turned back, saying: "The Academy of Sciences has moved to the new base in Xishan, this person's injury..."

"Carry it to Xishan and raise it, you are in charge!"

Zhu Qizhen didn't hesitate at all, and he wasn't even willing to wait for a second.

Because he has already realized the strategic value of the manned sky lantern that Mei Chun created.

The average altitude of Uzbek is more than 4000 meters, and conventional combat methods are difficult to be effective. Even if they win in the end, they will pay a huge price.

However, who said that it must attack from land?
"Yes!"

Beilin hurried down to make arrangements, but Mei Chun was a little confused and didn't know what to say.

Zhu Qizhen confessed: "The Qing family will suffer a little bit, go to Xishan to recuperate first, and be mainly responsible for guiding work in the early stage."

"what……"

Mei Chun was even more confused, with question marks all over her face.

Seeing this, Zhu Qizhen asked, "What questions does the Qing family have?"

Mei Chun thought for a long time, and then said: "Report to the emperor, the students missed Chunwei..."

"What are you still doing, go directly to the Academy of Sciences for an appointment!"

Zhu Qizhen waved his hand at him. For such a talented player, he should have made an exception to admit him.

Mei Chun said cautiously: "This...isn't appropriate?"

"Aren't you the Juren of Yingtian Mansion?"

"Yes……"

"It's enough to raise people. Besides, the Academy of Sciences is different from other yamen. Even if you don't have a reputation, you can still hold a job!"

Mei Chun wanted to ask something else, but seeing the emperor's impatient look, she swallowed the words again.

Then, he saw a group of people rushing in, carrying a stretcher...

The Kongming Lantern Institute of the Academy of Sciences was urgently established at the new base in Xishan.

The person in charge of the research institute is Mei Chun, and the members are elites personally selected by Belin.

Even Belin herself got out of the electric power laboratory and devoted herself to the research and development of Kongming Lanterns.

In fact, the manufacturing process of Kongming lanterns is very simple, and folk paper can be used to make them. The Kongming lanterns made by the Academy of Sciences have other uses and need to be made of leather.

Soon, most of the cowhide on the market was wiped out. When the cowhide was gone, they bought sheepskin and even dog skin. In the end, even the old shops selling donkey skin and donkey-hide gelatin lost their supply.

Next, is the key to this research, high air flow.

The ancients began to study the weather very early. When Mei Chun was copying ancient books, he found many similar books.

For example, Zhuangzi in the Warring States period proposed that the formation of wind comes from the influence of air flow, and mentioned that sunlight and wind can evaporate water, which further affects the magnitude and direction of wind.

The relevant legal system was formed in the Qin Dynasty, and all regions must report to the imperial court the situation of rain, as well as the area of ​​the world affected by rain or meteorological disasters.

In the Han Dynasty, during the period of Emperor Wu of the Western Han Dynasty, the "24 solar terms" were included in the "Taichu Calendar" as a supplement to the calendar to guide farming, and the solar terms were measured in the Yellow River Basin by using the Guibiao shadow measurement method.

In the book "Lunheng" written by Wang Chong, a philosopher of the Eastern Han Dynasty, he pointed out that the formation of thunder and lightning is related to the heat of the sun and seasons, and that thunder is caused by explosions.

During the Three Kingdoms period, people further grasped the relationship between the solar terms and the movement of the sun. In the "Zhou Bi Suan Jing" annotated by Zhao Junqing, the "Seven Balances and Six Spaces Diagram" was introduced, which theoretically explained the relationship between the 24 solar terms and the movement of the sun.

During the Jin Dynasty, "Xiangfeng Wooden Bird" and instruments for measuring wind direction were popular. Jiang Ji pointed out that floating clouds close to the ground can make the distance between stars smaller when the stars rise, and make the morning and evening colors red.Zhou Chu's "Feng Tu Ji" put forward the concept of plum rain.

Jia Sixie's "Qi Min Yao Shu" of the Northern Wei Dynasty fully discussed the influence of weather on agriculture, and proposed methods of using smoke to prevent frost and using snow to kill insects and preserve moisture; the "Zhengguang Calendar" of the Northern Wei Dynasty calendar included 72 climates in the calendar; Liang Zongmo of the Southern Dynasties "Jingchu Sui Shi Ji" divides the coldest and hottest seasons of the year.

During the Sui and Tang Dynasties and the Five Dynasties, Wang Bing divided the climate of the Central Plains according to the region. Du Taiqing's "Jade Candle Collection" excerpted the solar terms, government orders, agricultural affairs, customs, allusions, etc. contained in the books before the Sui Dynasty, and preserved a large number of lost agricultural meteorology. , Li Chunfeng's "Yi Zhan", which records the structure, installation and usage of the anemometer.

The Song Dynasty had a richer and more detailed understanding of meteorology, and was more precise in the prediction and calculation of rain and snow.

Shen Kuo, a geographer in the Northern Song Dynasty, "Mengxi Bi Tan", involved meteorological issues such as Emei's precious light, lightning, thunder axe, rainbow, Dengzhou Haishi, sheep's horn whirlwind, bamboo fossils, tile frost painting, the shape of hail, and the method of sailing. , vertical climate zone, weather forecast, etc.

In Southern Song Dynasty Shaoxing wine Qin Jiushao's "Nine Chapters of Numbers", there are four formulas for measuring rain and snow, explaining how to measure the depth of rain and snow on flat ground.

Then came the book "Tianjia Miscellaneous Zhan" written by Lou Yuanli at the end of Yuan Dynasty and the beginning of Ming Dynasty. It is divided into three volumes, the first, middle and lower.The second volume is divided into categories according to astronomical phenomena, namely the sun, moon, stars, atmospheric optics and cloud changes, etc., and object phenomena, namely birds, animals, grass, trees, fish, mountains, water, tides, etc., and uses a large number of weather and meteorological proverbs to forecast the evolution of the weather , climate change, and agricultural prosperity.The second volume is Sanxu, Liujia, climate, Juanji, auspiciousness and so on.

There are more than 500 records in the whole book, such as when the ground is very wet, the water drops are like a stream, which means heavy rain; if the northwest wind dissipates, there is no rain;

These records reveal some laws of weather and climate change from different aspects, and most of them are scientific and accurate.And quoted a lot of superb proverbs, such as "Although the upwind blows, the downwind does not disperse, and the main rain." That is, although the clouds in the upwind direction have dispersed, but the downwind direction clouds have not dissipated, it is a sign of rain.Using the movement of clouds to illustrate the convergence of high-air currents is an ingenious method and a correct conclusion.

The greatest value of this book is that while recording the weather, it systematically explains the formation of convective weather, and puts forward the original principle of wind force. It is believed that the solar radiation heats the ground and the air flow rises, which is called wind.It also records various weather averages such as sea breeze, land breeze, typhoon, annual and daily difference calculation method, atmospheric light phenomenon and other atmospheric phenomena.

After transcribing a large number of ancient books, Mei Chun summed up a complete set of experience related to air convection on the basis of predecessors, and recorded it in a book.

During these few days floating in the sky, he has not been idle, and the main job every day is to record.

This can be regarded as No. 1 in the measurement of air convection in person throughout the ages.

After coming to Xishan, Mei Chun was mainly responsible for technical guidance due to her injuries and limited mobility.

Belin personally brought a group of people to study air flow and how to control the height and orientation of Kongming lanterns every day.

The first batch of samples were quickly produced, but they were much smaller than the one Mei Chun made, and it was difficult to carry a dog, let alone a person.

Mei Chun was a little puzzled at first, but then she changed her mind, since it was a sample, it should only be used for testing.

"The first batch of Kongming Lanterns is ready for test flight!"

"Yes!"

Mei Chun saw that someone brought out ten Kongming lanterns, one group was responsible for recording, and the other group started to operate.

They first hung a brick on the bottom, and after checking it, they started to light the fire.

As the flames in the lamp became more and more prosperous, slowly, ten lamps flew up one after another.

"Report, No. [-] deviates!"

"No. [-] deviates!"

"No. [-] deviates..."

For some reason, there were lights that deviated from the expected direction and drifted away.

Belin sighed and said, "Make a record."

Mei Chun slowly stood up from the rattan chair and said, "Dean, the airflow is unstable now, and deviation is normal."

"You're right, the airflow is unstable now, but..."

Belin shook her head and said, "This is the difficulty we have to overcome!"

Mei Chun asked: "The higher the altitude, the more chaotic the airflow. Sometimes there is no way to follow. There is no way."

"There is no way, but we have to find a way!"

The first batch of samples all deviated from the expected position, and the experiment ended in failure.

Belin took people back, took out the pre-settings and on-site records, compared them carefully, and looked for the problem.

For some reason, Mei Chun felt a little depressed.

Because the previous theory was proposed by himself, none of the ten lamps in the first experiment met expectations, which made him feel a sense of failure.

"Mei Chun, tell me!"

"Ok?"

Mei Chun was in a daze when she was suddenly called by Belin, and she couldn't react.

"Judging from the records, today's wind direction is a bit abnormal. What do you think is the reason?"

"If the wind direction..."

Mei Chun withdrew her thoughts and began to think seriously.

"I think it has something to do with the heavy rain yesterday."

"Oh? Tell me in detail!"

"After the rainstorm, there will be water on the ground, and the sky will start to evaporate, and the speed of evaporation is related to sunlight and wind. Today's weather is very clear, and the speed of water evaporation must be extremely fast, which affects the wind in the sky..."

As Mei Chun explained, the other students quickly recorded and nodded.

After listening carefully, Belin said, "Can the direction and size of this wind be predicted?"

"It is theoretically possible, but at our current level, it can only be roughly predicted."

"Come and revise the plan, and conduct a second experiment in the afternoon!"

"it is good!"

Mei Chun took the original plan and made corresponding revisions and adjustments according to her own understanding.

He is the only person who has personally gone to high altitudes. These experiences are almost exchanged for his life, and no one else can replace them.

Two hours later, the second test began.

This time, ten more lights, each with a marked brick hanging beneath it, began to lift off.

Mei Chun's eyes were fixed on the trajectory of these lights, and her heart was extremely nervous.

"Report, No. [-] has deviated!"

Mei Chun's heart skipped a beat, and she was off again!
"No. [-] deviates!"

"No. [-] deviates..."

Every time someone reported a deviation, Mei Chun felt depressed, and he even wanted to do it himself.

"No. [-] has entered the expected orbit!"

The audience suddenly shouted, it's done!
Finally a light traveled the intended route and entered the target area.

At this moment, Mei Chun was moved and wanted to cry.

As the saying goes, a scholar dies for a confidant, thinking that he was summoned by the emperor, from an unknown student, thanks to the grace, he copied books in Nanjing, came into contact with a large number of ancient books and rare copies, and then sat on the Kongming lantern and came to Beijing after life and death...

While in heaven, he was even ready.

Prepare to fall to pieces, leaving no bones left.

At that time, the only belief in his heart was to hope to see the emperor again.
