Go back to the past and be a schoolboy

Chapter 223 Squeeze out the last remaining value (revised)

In a narrow sense, an aero engine is the driving force for aircraft flight, and in a broad sense, it is also the driving force for the development of aviation.

If the century-old history of aero-engines is divided, it can be roughly divided into two periods according to their specific technologies.

The first period was from the first flight of the Wright Brothers to the end of World War II.During this period, the piston engine reigned for about 40 years.

The second period is from the end of World War II to the 21st century, when aviation gas turbine engines replaced piston engines, ushered in the jet era, and dominated aviation power.

When later generations mentioned the development of our aviation industry, the most painful thing in the early stage was the aero engine. The technical problems could not be overcome for a long time, and it was necessary to purchase products from other countries. Every time this was mentioned, it always made many military fans feel sorry.

And this problem of congenital heart disease has always restricted the development of my country's air force, and the localization rate has also been discounted. It was not until the domestic Taihang series was released that it was considered a breather, but there is still a distance from the world's first-class level.

When it comes to the gap, many people attribute the problem to the fact that our development is too late, one step late, one step behind.

In fact, long before the outbreak of the Anti-Japanese War, our country had already begun to deploy in the field of aero engines. At that time, the gap between domestic and foreign countries was not too big.

At that time, Jiang Guangtou reorganized the Aviation Administration into the Aviation Committee, with himself as the chairman and Song Mei* as the secretary-general. It seemed that he strongly supported the domestic aircraft.

But in fact, after the members of the committee founded the machinery factory, they intend to manufacture aircraft engines, and have completed the transfer of aircraft engine technology with aircraft companies such as Curtiss Wright Aircraft Engine Factory and Brett Whitney.

However, Song Mei* stepped in, thinking that the cost would be too much, which would directly weaken the authority of his subordinates, and listened to the advice of the Italian consultant, abandoning the originally planned aero-engine technology transfer plan and turning to Italian technology.

If you want to say that Italy's aircraft technology is poor, it is not impossible to use it when it is introduced, but Song Mei* is procrastinating and refuses to pass the technology procurement plan. Finally, when the Anti-Japanese War broke out, the introduction of aero-engine technology was completely aborted. The technology gap has further widened.

This is not over yet, unable to bear the complaints from her subordinates, Song Mei* bluntly said: "I oppose the cooperation with the United States in the production of aircraft. I think it is far from urgent, and it is better to buy ready-made goods."

That's right, it's better to buy than to make. If you don't buy, there's no profit to be made.

Thinking of this, Cheng Nuo couldn't help but shook his head, thinking that Sichuan was the place to be. If the planes were built in Shanghai, Guangzhou, etc., they might be exploited by these compradors later.

However, there was still some time before Baldy Jiang took over, enough for Cheng Nuo to develop and accumulate.

Shaking his head to let go of the negative emotions just now, Cheng Nuo took three steps at a time, and soon came to the door of Krupp's workshop.

He happened to see Haber standing at the door, walking up and down anxiously.

Looking up and meeting Cheng Nuo, Haber immediately greeted him with both hands: "My dear friend, I finally see you. I miss you so much these days."

Looking at the other party's dusty look, Cheng Nuoxin said that your life is really great, and you actually survived the dual firepower of the French Air Force and anti-aircraft guns. You really have two brushes.

Although he thought so in his heart, Cheng Nuo's superficial skills were still very good, and he gave the other party a warm hug: "Dear Captain Haber, I haven't seen you for a few days, you are getting older, and you are about to make me want to die gone."

Haber shook his beard and said with an exaggerated smile, "Really? You should have boarded the plane with me to appreciate the beautiful scenery under the chemical weapons and fully appreciate the charm of science, so that you can become as young as me."

Cheng Nuo laughed loudly, let go of his arms and said, "Forget it, I'm afraid of heights, if I get on a plane, not only will I not be young, but I will also have to age a lot."

He knew that Ha Bo had something to do with him, otherwise he wouldn't have blocked Cheng Nuo here.

But since the other party refused to speak directly, Cheng Nuo was also happy to chat with the other party, anyway, it didn't cost anything, at most it was just some saliva, which wasn't worth much.

Before exchanging a few pleasantries, Haber couldn't hold back his thoughts, put away his smile and said seriously: "Dear friend, how much chemical weapons do you have in stock? I need them urgently, the more the more Well, there is no ceiling."

Cheng Nuo did not answer the question directly, but said with great interest: "So, the quality of the chemical weapons I provided is not bad, so why didn't we give me the experimental data that we agreed on at the beginning?"

"This... this." Haber was a little embarrassed, and explained: "The quality is indeed good, and the results obtained have exceeded expectations, but it takes a while to collect and sort out the data, and I am quite impatient, so I am eager to share this good news. After receiving the news, they flew back without waiting for the report.”

Cheng Nuo rubbed his nose: "I think sharing the news is fake, but urging the supply is true?"

Haber said cheekily: "How can it be fake? Both of these are true, but right now the Imperial Army really needs chemical weapons urgently."

Cheng Nuo shrugged and spread his hands: "But the experiment report was not given to me, and there was a crack in our cooperation, which made it difficult for me to maintain it."

Haber thought for a while, and finally gritted his teeth and said: "I am willing to purchase at double the price, as long as you can deliver as soon as possible, as a friend of our German Empire, you will definitely not suffer a disadvantage."

Cheng Nuo remained unmoved on the surface: "Money can't be earned. Compared with these, we care more about the experimental results and data. With them, we can develop better weapons, which cannot be bought with money. precious."

Of course, the more real reason is that the amount of chemical weapons that Cheng Nuo brought to Europe this time is not too much. After the previous few transactions, they have already consumed almost all of them, and there is only a little warehouse left.

Not to mention twice the price, even if it was twenty times the price, Cheng Nuo couldn't do this deal.

Even if it is because of money, if you insist on doing this business, it will be too late to ship directly from China to Europe. By then, Germany will have been laid down long ago, and all the weapons will be in your hands.

Hearing this, Haber became even more anxious. After wandering around the spot twice, he came to Cheng Nuo and said, "I will guarantee as a chemist. As soon as the experimental report comes, the façade will be handed over to you, and you will be returned to Cheng Nuo." It can be continuously improved, and other industry technologies and funds in the middle are easy to talk about.”

Speaking of this, it is not because the chemical weapons provided by Cheng Nuo are so advanced or how extraordinary the effect is, but in fact, it is because Cheng Nuo can provide a large number of chemical weapons that can be directly used on the surface, eliminating the need for a large amount of time in the production stage. the process of.

The battle that will determine the success or failure of the First World War is about to break out, and the gap on the battlefield is getting bigger and bigger. The process of research and development and production left for Haber and others is seriously insufficient. At this time, Cheng Nuo's value is infinitely magnified.

Just like that sentence said: If you don’t use the money to build national defense, are you planning to use it to pay compensation for defeat?
Haber naturally understood the reason, and stared into Cheng Nuo's eyes: "As long as you are willing to provide chemical weapons, we can even pay half of the deposit in advance. Whatever technology you want, we can solve it for you and guarantee to let you There is a satisfactory answer."

Seeing that the straight hook could still catch the fish, and the fish couldn't be thrown off no matter how hard he swung it, Cheng Nuo felt that he had coaxed too much, and wanted to squeeze out a last bit of money, so a smile instantly lit up on his face: "It's easy to say, easy to say , right now we just need some chemical technology, especially pesticides, we can discuss it..."

Maybe Gustav and the others in the workshop were impatient to wait, so they took the initiative to go out to see why Cheng Nuo hadn't rushed over yet.

Unexpectedly, Gustav, who just happened to see Haber and Cheng Nuo making a deal, thought he was cut off, and immediately shouted: "My dear friend, why haven't you come here yet, the aero engine is waiting for you to come here Let's start a fire."

Cheng Nuo immediately raised his head and said warmly to Gustav, "I'm sorry, I have something to do here, so I'll be there right away."

After saying this, Cheng Nuo did not forget to tell Haber in a low voice: "Remember, I need pesticide technology here, as long as you provide a feasible technical solution, not only can our transaction continue, but the scale will grow even bigger." It's getting bigger."

Hubble's face suddenly brightened: "What you said is true?"

Cheng Nuo raised his eyebrows, and instead of answering directly, he turned directly to Gustav.

Playing hard to get this trick made Cheng Nuo perfect.

After this operation, Haber was in a panic and wanted to continue to ask, but he was too embarrassed to speak directly in front of Gustav, so he had to say to Cheng Nuo's back: "You said, I will look for you again in a few days and promise to give you a satisfactory answer."

Cheng Nuo raised his arms and waved them in the air, which meant that he already knew.

Gustav on the other side came over in person and put his arms around Cheng Nuo's shoulders very enthusiastically: "The design of this engine is very novel. According to the conclusion of my engineer, its performance is at least in the top five in the current aviation industry. What are the details? The ranking will have to be known after the actual use after activation.”

Cheng Nuo had an expression of complete control: "Since we can take out this aero engine, it means that we have the confidence to not lose to the advanced level of the industry, and we will definitely give you a surprise."

Gustav nodded, and after taking Cheng Nuo two steps forward, he suddenly stopped and turned to Harper and shouted, "Captain Harper, I heard that your ability to fly a plane is less than your level of chemistry. Some, do you want to come in and take a look?"

Ha Bo was a little surprised, and originally wanted to refuse directly. After all, Cheng Nuo just gave him a big problem, and he must at least study some knowledge about pesticides when he goes back.

But thinking that this thing could be related to Cheng Nuo, there must be something great hidden.

Now that I have the opportunity to visit in the past, I will naturally not let it go.

"Well, I have admired Krupp's technology for a long time. Although we have been friends for so many years, we have not formally visited your company's workshop. Today, I just learned from Cheng Nuo. "Gustav laughed.

"Everywhere, everyone learns from each other. If you want to borrow the light, it is Captain Haber's light. Without your introduction, how could you meet such an interesting friend as Gustav." Cheng Nuo said modestly.

Gustav on the side was amused and laughed: "Learn from each other, borrow from each other, hahaha."

Following the three people's chatting and laughing, they soon came to the aircraft engine that had already been assembled.

Different from other piston engines, Tesla and Bayuzao developed a rotary piston engine, which is also the most popular style in World War I.

The biggest feature is that the crankshaft does not move, the cylinder rotates with the propeller, and the power-to-mass ratio is quite high.

Ordinary piston engines have high pressure and high temperature during combustion, resulting in high cylinder wall temperature.When the gasoline is injected, the piston spontaneously ignites before it reaches the bottom dead center, and the phenomenon of "knocking" occurs, which reduces the life of the parts, deteriorates the lubrication performance, and affects the life of the aircraft.

Therefore, the cylinder must be cooled, and the cooling method is usually liquid cooling, which requires that the gasoline piston engine must add water pumps, water tanks, coolers and pipelines, etc., and the total mass will increase a lot, which will lead to a reduction in the aircraft's bomb carrying capacity.

The rotary cylinder engine developed by the Academy of Sciences solves the above problems very well. Since the cylinder and the propeller rotate together, as long as it is started, the cylinder can be cooled better, so the cooling system is omitted. Play the role of flywheel balance.

Of course, this design is not the first of the Academy of Sciences. As early as the "Camel" fighter jet of the Sopwith company in the United Kingdom, a rotary engine was installed.The "triplane" launched by the German Fokker company is also installed with a rotary cylinder engine.

But Tesla is Tesla after all. With the addition of aviation talents such as Bayuzao, the performance of this engine is quite excellent.

With Cheng Nuo's ignition, the engine roared instantly, and the whole machine immediately burst out with a unique sense of power.

Looking at this engine, Haber couldn't help asking: "What is the maximum power of this engine?"

Without waiting for Cheng Nuo to reply, Gustav replied directly: "The engine of other manufacturers is at most 120kW. Our engine can reach 200kW, which is very powerful. With the addition of this heart, our Imperial Air Force will usher in a new era." A round of development will turn the tide."

Haber excitedly said: "So much power? Is it the technology of our German Empire?"

Without hesitation, Gustav said directly: "Of course it is, 100% original technology, star-shaped cylinder layout, the number of cylinders is greatly increased compared with the past, and it is a very effective solution to the problems of power output, weight and reliability. .”

After saying this, he did not forget to wink at Cheng Nuo, which meant to keep quiet.

And Cheng Nuo was so happy. In this way, the other party was willing to reach a cooperation directly from another angle.

This engine looks good, but it also has a lot of problems. The overall life is short, the fuel consumption is high, and because of the large mass of the cylinder, the gyro effect caused by the rotation makes the aircraft maneuverability poor, causing the aircraft to turn left very slowly, but turn right. Extremely fast, it's hard for new drivers to get used to.

A few years later, this type of aero-engine was eliminated, and Cheng Nuo moved it out at this time to squeeze out its remaining value, lest it be worthless in the end.

Sure enough, through Haber's mouth, the news of Krupp's successful development of a new type of aero-engine quickly spread throughout Berlin and won wide acclaim.

Cheng Nuo also took this opportunity to not only acquire steelmaking technology and artillery technology, but also abducted several high-performance machine tools along the way.

What kind of lathe, planer, drilling machine, etc., Cheng Nuo would not refuse anyone who came, as long as he was offered, he would accept it, and then use the ship of the intermediary country, and then transfer it back to the country.

When encountering that kind of giant machine tool, Cheng Nuo would find a way to secretly disassemble it into several parts, even if it was banned on the surface, and transport them back to China by ships from different neutral countries, and then assemble them when everything was almost ready.

The Germans also generously taught the principles of machine tool design, tool design methods, and techniques for adjusting machine tools for different purposes, allowing Cheng Nuo and others to get started quickly.

The reason Cheng Nuo was so interested in machine tools was also because machine tools were crucial to industrial development.

To give the simplest example, although it is said in books that the Watt steam engine triggered the industrial revolution, it seems that these things are not difficult to imitate.

But in fact, it was not until the invention of the Wilkinson boring machine that the cylinder boring accuracy limit required by the steam engine could be met, and then it was applied to industrial production on a large scale.

For Cheng Nuo, with the addition of machine tools, it is possible to gradually move towards the road of domestic industrial independence, and the design and production of various machinery such as guns, engines, agricultural machinery, and clocks and watches is possible.

Even if Cheng Nuo didn't want to invest too much in heavy industry, he could make continuous contributions to the development of domestic industry by only setting up a factory that produced machine tools.

But in general, this trip promises to be full of rewards. After digesting, I began to make ideas on famous scientists such as Planck and Einstein.

There is a saying that is good, come and come...
