Jiang Cheng shrugged and said, "This is a win for Tianlin, isn't it? By the way, Zifeng, are you here to cheat on me again? Or are you just cheating on the game?"
Zifeng took a nearby newspaper and threw it to Jiang Cheng and said, "Who wants to mess with your things? I have a mission. Look, you are so proud now."
Jiang Cheng took a look at the newspaper. The headline on the front page was that the "Joint Maritime-2013" Sino-Russian joint military exercise was held in the sea and airspace near Peter the Great Bay in the Sea of Japan in Russia. Jiang Cheng looked at Zifeng and asked, "This has nothing to do with me."
what is the relationship?"
Zifeng smiled and said, "Read it carefully, there are still many things in it that have not been written."
Jiang Cheng read it carefully. The article said that China and Russia deployed a large amount of new equipment in this military exercise. The most eye-catching ones were new submarines and new destroyers that used new energy batteries.
Jiang Cheng couldn't help but take a breath and asked, "Why was it exposed? How long has it been? And the military is too bold, right? It's too fast."
Zifeng said hehe, "Don't worry about what the military thinks. Anyway, your new energy batteries and new photovoltaic materials have been unanimously approved by the military. Now this submarine can be washed by just extending the board and letting the sun shine for a few hours."
The battery is fully charged, and the battleship is made to look like a nuclear power, but this is still an experiment on a small ship. If it really scales up, problems may arise."
Jiang Cheng hummed and said, "That's inevitable, but this kind of submarine reminds me of the Akula submarine in Red Alert 3. It is powered by solar energy. By the way, you think there is something else that is not mentioned in the article?"
"
Zifeng glanced at Kou Kou next to him and smiled evilly, then gestured for Jiang Cheng to come closer.
Jiang Cheng came closer uncomfortably. Zifeng leaned against Jiang Cheng's ear and said slowly, "This is a military secret, but I was specially approved by the Military Commission to tell you. Maybe the higher-ups are too happy. This time we
They used the darkness to secretly send J-20s using the paint you provided to fly over Japan for several laps, but no one noticed. This is definitely not intentional by the United States and Japan, but their radars are indeed unable to detect the movement of our fighters."
Jiang Cheng only felt his ears itching, and Zifeng's lolita figure made Jiang Cheng feel a little itchy. Jiang Cheng quickly turned his head and coughed and said, "As long as it's easy to use, I won't charge you more."
Zifeng wrinkled his nose, strode and stamped his feet and said, "Ahem! Comrade Jiang Cheng! Please stand at attention!"
Jiang Cheng was stunned for a moment, smiled, and Ge You lay down on the sofa and said, "Tell me."
An angry Zifeng stomped his feet and said, "Be serious, do you still want the award from the Military Commission?"
When Yu Na heard that it was the Military Commission, she gave Jiang Cheng a twist. Jiang Cheng patted Yu Na's hand and said with a smile, "It's okay." Then she looked at Zifeng, who was staring at her angrily, and then stood upright.
Zifeng said seriously, "According to the Chinese Military Commission's Order No. 182 in 2013, Comrade Jiang Cheng was specially approved to be promoted to the rank of major general and served as deputy director of the Seventh Department of the Ministry of National Defense's Equipment Development Department."
As he spoke, Zifeng handed Jiang Cheng his letter of appointment and said, "Take it, Major General Jiang."
Jiang Cheng said hesitantly, "Fallen title?"
Zifeng stuffed something into Jiang Cheng's arms and said, "Don't worry, it's just a false title. I don't know what you're afraid of."
Jiang Cheng took it with a smile and said, "Afraid of trouble, what about you? You should also benefit from the reward, right?"
Zifeng stuck out his tongue and said, "I won't tell you. Well, my mission is completed. By the way, the leader asked me to bring you a message. Chang'e will be launched at the end of the year. The leader has new expectations for you."
oh."
Jiang Cheng rolled his eyes and watched Zifeng leave.
Koko glanced at Yu Na, who nodded and returned to the room obediently. Jiang Cheng poured a glass of water and drank it while saying, "Don't bully our Nana, you two have a tacit understanding."
Kou Kou smiled and said, "The reason why Zifeng gave you the letter of appointment in front of me is not to remind me that you are registered in China. Here, these are the torpedoes and submarines you asked me to find for you last time."
Information, but I still have to warn you, this thing is really old, and submarines can harm maritime trade routes, so all countries are keeping a close eye on them, so don’t make it too big."
Jiang Cheng took it gratefully and said, "Thank you very much. How is the matter about the fighter plane?"
Kou Kou said, "The key to a fighter plane is the engine. The drawings of the engine are already in place, but do you have the manufacturing technology for the engine?"
Jiang Cheng nodded and said, "There are still some difficulties now, but can they be solved? Since Ying Tianlin is not in the country, let's stay a few more days."
Kou Kou looked at Ying Tianlin in a panic, looked away, touched her clothes and said, "Where do you live? Live... at your house?"
Jiang Cheng pointed to Yu Na's room and said, "You can sleep in Yu Na's room. If you like to sleep alone, I will let Yu Na sleep with me and you can sleep by yourself."
Before he finished speaking, a teacup flew over, and Jiang Cheng dodged.
"Who wants to sleep in your house! Bye!!"
Looking at the door being slammed shut, Jiang Cheng felt confused and asked incomprehensively, "What did I do wrong?"
——The next day
"There are several reasons why aero engines are so difficult to manufacture. One is that aero engines have very high material requirements. For example, rotor blades, especially those in the combustion zone, are subject to both high-speed rotational power and more than 2,000 degrees Celsius.
high temperature impact, so it must be heat-resistant alloy steel.
When using the same material, there will be processing technology problems. If the processing is not accurate, the repeatability of the blade shape will be very poor, that is, each set of blades will not be exactly the same, which will lead to a decrease in engine performance. Another example is that there are defects in the engine blade roots.
There are many small holes, and the cooling air coming from the turbine shaft flows to the outside of the blades through these small holes, taking away the heat from the blades. This cooling method requires very precise processing." Sun Ning said and looked towards
Jiang Cheng, whose eyes were already filled with stars, shook his head helplessly and said, "Ignorant of knowledge and skills!"
Jiang Cheng understood what he said and immediately retorted, "Isn't this inappropriate for professionalism? Then can we produce this material?"
Sun Ning shook his head and said, "This material is still from the late World War II. Even if you can't make it over there, you can get it from us. But the problem is assembly. The same material requires a skilled assembler and an apprentice."
If it comes out of tooling, the thrust-to-weight ratio may be higher by 0.2. This is also the value of skilled technicians. I think it is best if you can recruit some aviation manufacturing people from Europe and the United States to go to Yan'an, otherwise it will be very difficult to start from scratch."
Jiang Cheng thought for a while and said, "I have a lot of people who can repair airplanes, okay?"
Sun Ning thought for a while and said, "There are still differences, but these people have the foundation and can be apprentices."
Jiang Cheng nodded and took it to heart.
Sun Ning continued, "And we still lack one thing, and that is a hydraulic press, and a large hydraulic press is required. You must know that many die forgings can only be made using this kind of hydraulic press. For example, the die forgings on some modern aircraft require three
Only a 10,000-ton or even 80,000-ton hydraulic press can achieve this. Although your kind of aircraft is not needed yet, it is time to start developing it. These should not be available in Yan'an."
Jiang Cheng hummed and said, "Shanxi Arsenal has one two-thousand-ton model and six hundred-ton models. I have never heard of tens of thousands-ton models. There should be none."
Sun Ning nodded and said with a smile, "Don't talk about China. In 1940, there were not many people in the world with 10,000-ton hydraulic presses. Even Japan did not have such a thing at this time. I remember that Japan specialized in building the Yamato and Musashi.
Germany imported two 15,000-ton hydraulic presses. At that time, Germany and the United States were at the forefront in this regard. Even the Soviet Union also obtained more than 10,000-ton hydraulic presses from Germany. Having said that, you must have this thing
We need to pay attention to it. Without this, we should not even think about heavy equipment, fighter jets, or aircraft."
Jiang Cheng thought for a while and said, "I remember this thing is very big. The first domestically produced 10,000-ton hydraulic press in the textbook was more than 30 meters high. Even if I pulled this thing over, there was no place to put it."
Sun Ning knocked Jiang Cheng on the head and said, "Who wants you to go to such a big one at once? Can't you learn from your ancestors? Back then we also built a 1200-ton one first. In order to test the 1200-ton one, we first built a 120-ton one.
But now that we have the foundation, we can first try the one of about 1,000 tons. During World War II, the United States built more than a hundred small and medium-sized die forging hydraulic presses in order to destroy fighter jets, battleships, and tanks, but the largest was only 5,000 tons.
One thousand tons is enough for us, can we add more in the future?"
Jiang Cheng hummed and said, "Okay, let's do it this way. Can you collect this material? I'll bring it over next time."
Sun Ning nodded and said, "Although this thing is expensive, it won't matter if we only make small ones. Now there are thousands of tons in the world, but your goal is not to make Yan'an self-produced, so you want to ask for information
Or should I take my things with me?"
Jiang Cheng hesitated for a moment and said, "Just the information, I won't bring anything with me. Didn't you say that Germany is very good at this? I'll just go and recruit people."
Sun Ning smiled and said, "You are very enthusiastic about poaching people. In fact, there were small hydraulic presses in China at that time. I remember that Li Hongzhang proposed to buy a hydraulic press in the 13th year of Tongzhi. Within a few years, Jiangnan Manufacturing Bureau
I bought a 2,000-ton hydraulic press, which was extremely advanced at the time, and later there were three in Hanyang.”
Sun Ning said with some sigh, "In fact, in the 21st year of Guangxu's reign, Jiangnan Manufacturing Bureau even produced a hydraulic press."
Jiang Cheng asked with interest, "What about the Republic of China?"
Sun Ning shrugged and said, "There are some in the Northeast, and they are given to the Japanese. You know, there is one in Shanxi, and one in Kunming. The ones from Jiangnan Manufacturing Bureau and Hanyang were originally intended to be shipped to the rear, but they disappeared. How can such a big thing be unknown?"
The whereabouts are also a matter of skill."
Jiang Cheng twitched his lips in embarrassment. Although he had mobilized for a retreat, he didn't know much about the military factory. However, looking at the current military industry strength in Chongqing, there should be no changes.
Jiang Cheng said, "Let's mount the three thousand tons first. By the way, why weren't you here last night?"
Sun Ning put her hand on Jiang Cheng's shoulder with a sweet smile and asked, "What? Miss me?"
Jiang Cheng took advantage of the opportunity to hug him and said, "On the one hand, I miss you, but on the other hand, I am now a major general, do you know?"
Sun Ning hummed and said, "I know, I was wondering when you would get it before you say it."
Jiang Cheng asked, "What does it mean this time? So many things were exposed."
Sun Ning let go of his hand, sat aside and said, "It's very simple. New photovoltaic materials and new batteries have already caused heated discussions around the world. Other countries will naturally guess that we will use them in the military. This time, it is to deter the United States."
The second one is also to hype your battery. It is predicted that the economy will become more and more difficult in the next few years. We urgently need to have competitive products, one for high-speed rail, one for nuclear energy, and then your photovoltaic."
Jiang Cheng then calmed down and said, "That's it, that's good. I'll go back in a few days. I've been putting it off for almost half a year, and I can't put it off any longer."
——Germany in the time and space of the Republic of China
"This is the blueprint for a new submarine?" Dönitz said with shining eyes as he looked at the long blueprint.
Jiang Cheng nodded and said, "Our current Type VII submarine has a total length of 67 meters, an underwater displacement of 865 tons, an underwater speed of only eight knots, and only 14 torpedoes. But my new submarine has a length of
76.7 meters, with an underwater displacement of 1,800 tons, more than double the size. The most important thing is that it has three outstanding improvements, one is speed, its underwater speed can reach 17 knots, the other is sound, which is quieter, and
One is the attack power. It can fire six torpedoes every ten minutes or so, but the original old submarine couldn't even load one torpedo in ten minutes."
Dönitz's eyes almost fell out of his head. He asked in disbelief, "Is this... is this true? Which genius designer designed this? No! This is not a masterpiece that can be completed by one person. This is...
It's a completely different kind of weapon."
Jiang Cheng patted Dönitz and said, "Why bother with where he came from. Our problem now is how to produce him. Good weapons will naturally be much more expensive."
Dönitz asked "How much more expensive will it be?"
Jiang Cheng pointed to the Type VII submarine on Dönitz's wall and said, "Three ships for one."
Dönitz took a breath and murmured, "This is really expensive."
Jiang Cheng sighed and said, "This good product is not cheap. If it is cheap, it is not good. I want to build one for 100 marks. Do you dare to use it? However, if modular production is used, the price may be lowered."
Speaking of this, Dönitz said helplessly, "I'm already using the method you mentioned. Modular manufacturing is indeed cheap and fast, but it brings another problem."
