When the sun sets, everyone walks to a fork in the river to see the wonders, and it is simply empty.

This is a model of the Daimyo's mansion, and it was the first machine in the Great Song Dynasty to use hydro energy to generate electricity.

The principle is not complicated, whether it is Zhuo Luolan or Fujiwara Mitsuko's territory, there are waterwheels, but the new waterwheel personally built by Shen Kuo in the Daimyo Mansion is different, no one knows what the principle is inside, but this small waterwheel can produce something called electricity, connected by two soft wires, everyone witnesses a small iron bump, can spin with fan blades by themselves?

It's really amazing, especially for people from Western Xia and people from Japan, now the three women each rely on their "gentle" identities to squeeze ahead, and finally go to the front row to witness all this.

Nozo Blue Rain and Fujiwara Mitsuko thought it was magical, and they got closer and closer in a trance.

Most of the people of the Song Kingdom were also shocked, to say that they had seen internal combustion engines and steam engines, they were all rumbling and moving, but they had to be filled with specific fuel. But this little thing called a motor, neither rumbling nor smoking, the two connected wires cannot provide visible power, but it can drive the fan blades, and the wind is not weak?

"However, I still don't know what the Great Demon King is doing with this thing?"

"Yes, with the rotation of such a large waterwheel and the rotation of such a small blade, it seems to be miraculous but useless, and the project of cheating funds has been supervised."

"I don't know."

"Sit back and wait for the power to interpret it."

The onlookers and the people began to talk.

"Yaga!"

At some point, he heard Yanagi shouting strictly, because he was too involved in squeezing too close, he thought that Fujiwara Mitsuko was offended by the blue rain of no rose, and he had met a female liar and was in a bad mood, so he yelled: "I don't know whether to live or die, this is the daughter of my father-in-law!" ”

"What kind of roar, what scene haven't you seen in this palace?" I don't look like I don't care.

Zhuo Luolan pulled Princess Lanyu behind her and apologized: "Her Royal Highness the princess of my family is a little delirious, please forgive me for the offense." ”

This made the people around him very interested, thinking that they could see a group of gentlemen from all over the world fighting, either a princess or a certain prime minister's family.

As a result, they were all guests of the Great Demon King for a long time, and they couldn't tear it up.

Now the big cities of the Great Song Dynasty are so virtuous, and the powerful are all over the streets, and there are many people like dogs, especially in Tokyo.

Liu Sheng was depressed for a while, and was deceived by a female hooligan with a sword a while ago, which was a shame for the samurai, but he was a close friend of the Great Demon King, and he couldn't find a place to come back. Seeing that these two women were not Song people this time, I thought I could bully them, but when I heard that this was a "dream aunt" from Xixia, she was delirious and mentally ill, but she was also a close friend of the Great Demon King.

Let's continue to watch the generators.

The eyes of the ordinary people of the Song Kingdom are bright and they dare to tell the truth!

In fact, although Yanagi Yin Yan and Fujiwara Mitsuko thought this thing was magical, but just like that, they didn't know what the meaning of this was other than showing off their technological muscles, and it was indeed quite using the drop in water power to push the fan blades. However, after the fan blades of the big waterwheel are pushed, they drive the fan blades of the small iron bumps to rotate.

"What's the point?" Liu Sheng Yin Yan and Zhuo Luolan asked in unison.

Lan Yu and Mitsuko Fujiwara replied in unison: "I don't know how strong." But the Great Demon King must have a way of doing things, but we just haven't figured it out. ”

"Shen Kuo, Lord Shen Kuo is here......"

The onlookers suddenly heard someone shouting like this.

Fujiwara Mitsuko had also heard of Shen Kuo's name, and knew that he could answer, so he looked around: "Where is it, I must ask what is the use of this generator?" ”

"...... in Heaven"

The common people of the Daimyo Mansion didn't think it was strange to see it, but when Zhuo Luolan and Fujiwara Mitsuko looked up together, they almost fainted, and there was really someone who could fly in the air?

I saw Shen Kuo driving a big kite, with a propeller connected to the pedal device, and he shouted while pedaling the pedal machine in the air: "The front is scattered, I can't hold it, this official is going to make a forced landing!" ”

Then everyone watched with their own eyes on the newly repaired asphalt road in front of them, and after a steady slide, they stopped.

For now, no one else can approach, but Fujiwara Mitsuko and Musashi Blue Rain have so-called diplomatic privileges and can run over to watch Shen Kuo's glider.

When they got closer, they reached out and touched the glider in amazement.

It's amazing, not to mention the magic of this thing that can fly into the sky, just to say that it can use such a light material to make this thing so strong and not fall apart, and the connection process is almost perfect, and the overall design idea is ingenious, all of which show ingenuity.

"Absolutely! Such an experience cannot be obtained if it is made in the Song Kingdom, which is the spirit of craftsmanship. Mitsuko Fujiwara commented, "In the future, we must also have the spirit of craftsmanship ourselves." ”

Shen Kuo gave a thumbs up: "Sure enough, I know the goods." ”

This is really the crystallization of ingenuity and craftsmanship, this humble thing is not a kite, and it cannot be made anywhere else.

Today's gliders are not papier-mâché long ago. It's all made of wood, and even the cloth is useless, it's all wood. Therefore, it is necessary to select wood with very light specific gravity and similar performance, and carry out special process treatment and connection.

The overall weight should not be too heavy, but under the limited weight of the structure, it is necessary to achieve the strength and cohesion process in many places without mistakes, even if it is the joint research and development of Shen Kuo and Lao Luo's team, it has taken many detours.

The articulation of funny wings is the most problematic, and the earliest articulation process is blown in the wind tunnel, and after the wings reach a certain lifting force, they fall apart. Calculate that the Great Demon King's brain is out of the wind tunnel, otherwise it is impossible to estimate how many people will die during the test.

The reason why it is now over-the-top to attack the wood craft fuselage is because the Great Demon King has already instructed on the route: the first and second fuselages with flying machines will definitely be wood, and metal cannot be used.

First, there is no need for that kind of strength now, and the aircraft will not have a great load-bearing capacity for the time being, nor will it have the need for super-maneuverability at a speed of 150 knots for the time being. In this case, the wood body can improve energy efficiency.

Secondly, it is impossible to have a gas turbine with a sufficient thrust-to-weight ratio to push the metal fuselage up within five years. The wood technology is already very advanced, and a lot of wood technology and experience have been accumulated in the research and development of the god arm bow material and flat-bottomed wooden boat. It can ensure that the strength is enough at the same time, the weight of the whole machine is compressed to a very low level, so without pursuing a speed of more than 200 knots, the big devil said, according to the current gas turbine volume and weight, as long as there is a thrust of 900 catties, the agricultural aircraft can fly.

This kind of thrust is difficult to say, but according to the gas turbine now manufactured by their internal combustion engine factory, there is already half of the thrust, and when the next generation is designed and the process is almost excavated, it can go to the sky, Shen Kuo thinks that it will only take two years at most.

Although the Great Demon King said that "a responsible big country does not need to use military force, this is an agricultural machine", but the ghost believed him, such an aircraft can be named Vulcan bomber, since it can be used for agriculture, it can also pass by the enemy position with two hundred catties of incendiary bombs. This kind of passing, as long as there are three hundred sorties, the scale of the flames will surpass the Battle of Chibi.

And the larger the scale of the campaign, the easier it is to use. So the Great Demon King has given a lot of money on this project. So much so that Shen Kuo's old Luo Dad and their chicken blood, burning money to play with materials, it was like running water, how many of these high-value fuselages cast by high technology fell apart in the wind tunnel, Shen Kuo himself didn't remember how much.

But because of these accumulations, the research and development has basically come to an end, and the wood body with a strong enough weight-to-weight ratio is almost about to be born.

"This ...... How is this thing going to be made? Fujiwara Mitsuko stupidly touched Shen Kuo's glider.

"It's not a secret that you can just draw a drawing of the exterior here if you like. But there are too many inner doorways, and if you don't have enough foundation, you can't get out even if you invest in the country for ten years. I used to think I was very good, but it wasn't like that at all, and it was really lucky that I didn't fall to my death. Once the wind was strong and the gliding test reached a speed of 75 knots, I thought it was free, I thought it was fun, I did a strong maneuver, and the body fell apart directly in the air at least twice, and I brought a special umbrella to not fall to my death. ”

Shen Kuo looked extraordinary.

"Can you really draw it?" Zhuo Luolan bit his finger and said.

Shen Kuo didn't have the patience to serve them, and waved his hand when he left: "As you like, if you want, you can sell one to you, it's just expensive." It's useless for you to buy it, and you'll kill yourself without my experience. ”

"That's right, Lord Shen." Fujiwara Mitsuko followed his footsteps and said, "What is the purpose of the waterwheel power generation device you designed in the estuary?" That is, in Han Chinese parlance, that seems to be taking off your pants and farting? ”

Shen Kuo said as he walked: "You don't understand this, the motor does have no use value for the time being, and copper needs to be used to pile up materials, and the Great Song Dynasty lacks copper." Therefore, it can only be used in special fields, and I have determined the output of the motor in the next generation of 201 super large wind tunnel, and the horsepower can be as large as it wants, and the output linearity is quite perfect, and the speed regulation is simple and stable. As long as a few more sets of steam engines are used to supply power to the motor, a large wind tunnel can be built, which can test the wind parameters of a 10,000-kilogram aircraft. It's useless to tell you for that purpose, is it? ”

In this way, Shen Kuo went farther and farther. Leaving the three big beauties and Yanagi Yin Yan looking at each other.

This is already a forbidden area, it is the test site of the Aviation Institute of the Industrial Division, but as Shen Kuo said, the patrol soldiers don't care about them, except for not allowing them to enter various factories and laboratories, no matter what methods they use to "indecent" the aircraft, no one cares.

So I saw three women always touching and touching around the small flying machine.

Just enough for one person to sit. Seeing that the patrol soldiers did not stop him, Fujiwara Mitsuko sat in and tried to pedal like a spinning bike, with a large speed ratio, and there was no need to be fast, so he brought a lot of wind power from the propeller.

But when the propeller is almost to a certain point, the drag from the air on the propeller is frenzied, and no matter how hard Fujiwara Mitsuko can't improve, the glider won't move, and her feet will go limp.

"I'll try!"

As a master, Liu Sheng Yin Yan sat on it, and he was able to step on the big speed pedal machine like a propeller.

Khan, the aircraft really moved, getting faster and faster on the runway. When the glider passed by Shen Kuo's side, Shen Kuo couldn't help but faint, this guy is a powerful machine with a 1:20 thrust-to-weight ratio? Awesome, can you achieve such a cadence? It seems that only Mu Guiying can do this, but the eldest lady doesn't like to do these things.

It's a pity that Yanagi is an uneducated Qiu Ba, if he can operate the lever, and his foot strength is not exhausted, and he can maintain this power output, he can already pull up and take off.

It's almost too much for them, and after Shen Kuo nodded to the soldiers, he touched-

Someone began to fire warning shots, signaling Yanagi to stop.

However, overestimating Yanagi's intelligence, he didn't know where the brakes were, and he didn't remember to slow down the reactionary propeller, so he could only watch the glider finally hit the wall and fall apart.

Seeing that Shen Kuo's face turned green with anger, Zhuo Luolan slipped away with the blue rain, pretending not to know them.

"Idiot ......" Fujiwara Mitsuko didn't dare to run, and raised his hand to cover his face with numb scalp, and other people's black technology was damaged like this.

After covering her face, she let go of her fingers again, and when she saw Shen Kuo walking back, she had to bite the bullet and say, "How can this be good?" ”

Shen Kuo said: "It's okay, it's okay, I don't want this one to be built well, just lose money." ”

Fujiwara Mitsuko breathed a sigh of relief, as a gentleman, since silver can solve it, there are several silver mountains at home. At this point, she was nervous again, of course, even if it wasn't bad for money, it didn't affect her thinking that Yanagi was a big idiot......
