Go back to the past and be a schoolboy

Chapter 171 The First All-Metal Aircraft

"Hey, Papaya, tell me how the chair in our training ground is designed. It can only turn left and right, but when I put on the blindfold, I feel that I am turning at 36 degrees without a dead angle. I was so scared I jumped up."

In the cafeteria, after training, half-grown boys started queuing up for food, and a few fast runners were already sitting together and started to eat.

Talking about the training in the morning, many people began to complain, especially when it came to subjects related to pilot selection training, they were full of bitterness.

"Our friendship is friendship. I told you before, don't call me papaya." Xia Sigui was named "papaya" because of his big and round head. He was very sensitive to this, and immediately put down the chopsticks in his hand: "Call me this again, I will never end with you!"

Chen Tiancai shrank his neck, not daring to touch the bad luck again, and took a piece of food for his fellow countryman: "Come on, I'm sorry, eat this quickly, while I'm transferred today and I don't have any appetite, these meats are all yours, don't What a waste."

It was also because the recent training was getting more and more tiring, Xia Sigui slowly accumulated some nameless anger in his heart, and this was why he became angry because of trivial matters. Seeing that his fellow countrymen had apologized, he felt a little guilty, and pushed his vegetable soup over: "It's okay not to eat, and there is training in the evening.

Even if I can't eat the hard ones, I still have the soft ones. Drinking some egg drop soup can at least cushion my stomach. "

"Then I'm not going to be polite, let alone, our chef put some seaweed in the soup, and it still tastes like seafood." Although his mouth was happy, he brought the soup to his mouth, and gave it to him again. Putting it down, Chen Tiancai said with lingering fear: "You said that you drank a stomach full of water, will it feel better in your stomach when you turn around.

Swaying and swaying, I guess I vomited even more, you don’t know, there seems to be someone next to us who is always scoring according to our performance, don’t make it so bad in the end, kick me back to my hometown to farm, grow such a big meal, I haven't eaten much here in the past few days, so I can't bear it. "

Xia Sigui was taken aback for a moment, then asked curiously, "Then what do you want to do with the plane?"

What's more, after Liang Qichao came down, he could just connect him in.

……

While the two were still thinking, Cheng Nuo found an excuse and ran away before the team of "school workers" running behind them had formed.

Bayuzao gritted his teeth: "I still insist on my opinion. Scientific research must be done step by step. It is not in line with the laws of natural science to want to eat a big fat man in one bite, unless we can directly find suitable metal materials, but this is too difficult. Given our current The domestic industrial base is almost an impossible task."

In this way, the boss collapsed, and Duan Qirui's cabinet was disbanded logically.

Jiang Baili understood the meaning of his eyes, most likely he wanted to say that he was busy with the aviation school every day, and he was all the shopkeeper here.

Including strength quality, speed quality, endurance quality, flexibility and sensitivity quality, etc., but some training is too difficult, and these "school workers" can't bear it directly. The specific training subjects are also a process from simple to complex .

Later, after many improvements by Wilm, he successfully applied for a patent for aluminum alloy. Because the registered company is Dura, the material is also called "Dura Aluminum".

Wang Zhu hesitated for a moment and said: "Currently mainstream European aircraft, the fuselage including the frame, pillars and wing ribs are made of spruce wood, the propellers are made of walnut wood, the wing skins are made of linen, and only a few load-bearing parts are made of spruce wood. Metal poles, all-metal aircraft are only theoretical at the moment.”

Walking to the cinder track, Cheng Nuo simply trotted: "It's just that these are not enough. We lack everything else, but we don't lack land. According to the manual I gave you, build a 250m circular track, a 400m obstacle course, Fixed rollers, Trojan horses, assassination paraphernalia."

Others may appear to be "idle", and the number of training instructors will increase later. You can divide into teams and enrich the training methods. "

From time to time, some pilot selection subjects are interspersed in the middle, and the flying seedlings are gradually selected from them, so that they can be thoroughly distinguished later.

Looking at Bayuzao, Cheng Nuo said seriously: "Then we must be the leader. The development of aviation technology will inevitably drive the development of aviation materials. The transition from wooden aircraft to all-metal aircraft is a historical necessity."

"Wuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuh." Chen Tiancai wanted to say something instinctively, but it was a whining sound. Then he remembered that a steamed bun was stuffed in his mouth, took a big bite, and said while chewing: "I Not as childish as you."

In layman's terms, it is to use the method of rotating the swivel chair to evaluate the students' ability to resist high-altitude rotation. If there is extreme discomfort after the rotation, it is definitely not suitable for pilots.

Xia Sigui picked up the steamed buns and stuffed them into the mouths of his fellow countrymen: "If you don't tell me, I won't tell you, who knows, I'm doing it for your own good, that's flying a plane, don't you want to fly a plane and stay at your house?" Showing off on Tweety's head?"

This is what Cheng Nuo wanted, and he laughed loudly: "Han Xin ordered troops, the more the better, the more the better! Don't you think so, Lao Zai?"

"The potential of wooden planes has been exhausted, and we can see the head at a glance. We are still young and have almost no sunk costs." Cheng Nuo shook his head with a smile, and said, "Take the European War you mentioned as an example. Performance has been significantly improved.

Xia Sigui's face darkened, and he didn't want to worry about the nickname anymore, so he said angrily: "If you like to try it, try it, if you don't like it, I will sprinkle flowers on Tweety's head for you!"

Just in time for Jiang Baili to come back from the place where the aviation school was set up, Cheng Nuo specially called him and Zai Tao to press the road on the playground again.

By the way, he complained that the south had conspiracy, alienation, and children to divide the north. It began to attack the north with the north, and then attacked the north with the south, and finally the species was extinct and then quickly.In order to avoid the division of the North and the division of China, there is no other way to save it than to resign.

Seeing this, Jiang Baili rubbed his nose, and took the initiative to take a step forward: "With so many projects added, Mr. Zai and I really can't do it at the same time. Dean, can this work? I also have a few friends in Baoding. At that time, I was in charge Physical training, I'm still at home now, if you don't mind, I can contact them."

Xia Sigui was obviously much smarter. When he saw that everyone was seated and started cooking, he gestured towards his fellow countrymen and said in a low voice, "Actually, it's also simple. As long as you quietly expose the blindfold while the swivel chair is turning, look You won't get dizzy when you go to the outside scene."

"Dean, I still say the same thing. Our first plane is mainly conservative, and it is better to make it wooden. Not only am I proficient in making it, but the European battlefield has proved the excellence of wooden planes." Bayuzao saw Cheng Nuo came over, spread out the design drawing that had been prepared, and stated his point of view.

After thinking for a while, Cheng Nuo slowed down and said, "In addition to this, there are waves, climbing ropes, climbing poles, software, etc. These equipment are very important for improving the balance and climbing ability of our janitors. It’s a good one not to drop all of them.”

As soon as this side was dismounted, the Acting President Feng Guozhang over there resolutely ordered Duan Qirui to be removed from the post of Prime Minister of the State, and Wang Shizhen was specially appointed as State Premier. dismissed.

As for this "transfer", that is, the double test of rotation, it is just an appetizer for the pilot's daily training, and it is counted as a preliminary screening.

In fact, the discovery of aluminum alloy can be traced back to 1906. In an experiment, German metallurgical engineer Alfred Wilm found that the hardness and strength of aluminum alloy containing certain other metal components increased, thus giving birth to the world's first aluminum alloy. The first aluminum alloy.

Chen Tiancai was startled when he heard this, and almost overturned the soup bowl when he pulled his hand back: "You are cheating, be careful that the instructor knows to settle accounts with you."

Chen Tiancai's eyes were crescent-shaped, and he said with a naive smile, "I have to pinch some flowers and sprinkle them on Tweety'er's head, so that she can be the most beautiful woman in all towns."

The corners of Xia Sigui's mouth twitched: "Look at your virtues, you're only promising."

"Aluminum alloy!?" The two said in unison in surprise.

However, Cheng Nuo is a theoretical school after all, and in terms of practical work, he has to rely on the two people behind him.

Cheng Nuo smiled and said: "It's still the same sentence, we must do our best when we do it. I don't want the plane we have worked so hard to build, it will be a version behind the world just after the test flight, and it will always be on the road of catching up. What I want, I believe it is not what you want."

"Who said it's impossible to complete the task." Cheng Nuo raised his eyebrows, and the corners of his mouth rose: "I think aluminum alloy is very good."

Wang Zhu was a little moved: "Due to the special requirements of aircraft flight, this kind of metal structure needs to be light and strong. Where can we find these materials? It will be a long and cumbersome process to prove it, unless we can do it all at once." Can test out qualified materials."

But right now, he didn't mean to explain. He followed Cheng Nuo and said, "I met some friends when I was teaching in Baoding Military Academy. When the time comes, I can bring over their idle things and save us the trouble of building."

After taking a look at Jiang Baili, Zai Tao took the initiative to say: "Okay, I will add a few more wooden stakes and parallel bars later."

Zai Tao's recently wrinkled face finally relaxed a lot: "Yes, the more the better, the effect of our training here should pave the way for Mr. Jiang's aviation school."

But right now, the matter of the aviation school is more important, especially when the mechanics of the aviation school are trained and they are only waiting to build airplanes, they need Cheng Nuo to make the decision.

Fortunately, Cheng Nuo felt it and supported him in advance.

Cheng Nuo smiled, and didn't answer the words. Instead, he paused and looked at Jiang Baili meaningfully.

The heroic spirit of "I don't go to hell, who will go to hell" is actually because he can't beat Feng Guozhang in the dispute between the court and the court, so he puts gold on his face.

The so-called swivel chair training is that Cheng Nuo and the others use the method of rotating double test to screen the vestibular function of the pre-pilot, and the vestibular function is one of the three main factors to maintain the balance of the human body.

After all, he has already done everything he can do in this regard, and directing is a bit like an outsider instructing an insider. The training effect may be greatly reduced because of this. It is better to formulate a framework and let these people let go of training.

"Dean, I'm sorry, it was my negligence. I will arrange for them later." Zai Tao apologized repeatedly.

In fact, he sent a secret telegram to the generals of the Beiyang faction, thinking, "Looking around the country, only our soldiers in the north can protect the law and protect the country.

"Don't, it's up to me..."

Bayuzao looked at the aircraft he had designed himself, and felt a little bit unbearable: "But to overthrow and redesign, we almost start from scratch, basically there is no object to learn from."

Especially now that Tianjin is not peaceful, Duan Qirui resigned to Acting President Feng Guozhang, ostensibly to avoid the limelight and avoid confrontation between the North and the South.

Chen Tiancai rubbed the back of his head, a little embarrassed: "Papaya, does the method you said really work? I always feel uneasy. I heard that the thing was designed by the dean himself, so we broke it like this?"

The engine power is increased to 296 kilowatts, the flight speed is about 200 kilometers per hour, and the ceiling and range are greatly improved.But it is precisely because of the increase in the speed, maneuverability and load of the aircraft that wooden materials are gradually unable to meet the demand. "

And this is only a small part of Cheng Nuo's training reforms for these "school workers". The rest are similar to 400-meter obstacles, fixed rollers, waves, 5 kilometers of armed cross-country, assassination, rope climbing, software climbing, etc. .

Understanding what the two of them meant, Cheng Nuo didn't intend to get involved directly, but ran forward again: "However, you still have to pay attention to the fact that the time for physical training is too concentrated and the training content is relatively unified according to the organizational training. Some venues and equipment will be overcrowded,

"While you are all here, I still have to give special instructions, especially in terms of physical training. Venues and equipment are essential tools for the general military special forces to conduct physical training. Sufficient venues and equipment will make all physical training plans If the implementation is guaranteed, it will increase the practice density of the trainers, and then achieve the purpose of improving the training effect.”

Zai Tao was listening and memorizing. Because he listened too carefully, he didn't notice that Cheng Nuo in front of him slowed down and almost bumped into him.

After finishing speaking, he directly pushed the soup over, making it clear that he didn't want to drink it, or that he didn't dare to drink it.

The politics were so turbulent, for the sake of personal safety, Cheng Nuo naturally couldn't stay in one place for too long.

Although pure aluminum is extremely soft and cannot be used as an aircraft material, duralumin is an alloy of aluminum, copper, magnesium, manganese, etc., which belongs to heat-treatable aluminum alloys.After heat treatment and aging treatment, duralumin has become "harder" obviously, its strength has been increased by 7 times, and it has higher mechanical properties.

Components suitable for manufacturing aircraft, such as skins, panels, strips, wing ribs, etc., have greatly improved performance compared with traditional wood.

Since then, it has caused a revolution in aircraft structural materials, and wooden structures have gradually given way to aluminum alloy structures.

It is a pity that until 1917, when Cheng Nuo lived, wooden aircraft still ruled the sky, and few people dared to use metal to build aircraft.
