Chapter 449: No matter how small the ant is, it is meat

"Professor Zhang, this batch of information was obtained through the secret department, so it must be kept secret. I hope you will lead your students to thoroughly understand these technical information and produce qualified turbine blades as soon as possible. Then, these technical information can be used. Treat it as your own scientific research results." Qin Guan solemnly transferred the entire box of materials to Professor Zhang.
Qin Guan's words caused Professor Zhang to shook his head immediately: "No, isn't that doing false scientific research? How can I sign my own name on the results of others? Absolutely not."
In later generations, those so-called technicians were all trying to get fame and reputation. They bought chips from abroad, polished them with a few migrant workers, and painted them with their own logos, and treated them as their own products. Then they fooled people around and defrauded the country’s scientific research funds. .
Such a person should be sentenced. It is a standard for fraud, and it is the country that is also defrauding.
Look at the current scientists. They are extremely rigorous, and they are all for the country, not for their own fame. People are the real scientific and technological workers.
Professor Zhang shook his head, opened the box and turned over the materials inside. After just flipping through it like this, he suddenly exclaimed: "Great, great, how did these materials come from? I want to do experiments immediately. !"
Professor Zhang was overjoyed.
Qin watched over, and what she held in her hand was part of the single crystal.
They are all metals, and they are arranged in different ways, and the characteristics they bring are also different. For example, diamond and graphite are both carbon, but they are arranged in a different sequence. If precious diamonds are completely melted and then solidified, Become graphite.
Diamond has a very strong hardness, but graphite is not good enough, which is caused by the different internal structure.
If you want to manufacture airplane turbine blades, the internal crystals must be arranged as needed and neatly arranged to have excellent performance. After all, the blades in the aircraft engine work in the worst environment, with high temperature and high speed. If the internal structure of the metal is not suitable, the blade breaks are too common, and the blades with tens of thousands of revolutions break and fly out, and the entire engine is immediately scrapped.
Therefore, the crystals inside must be neatly arranged, just like a military training team, which requires a special method, which is generally a directional solidification method.
Although the turbine blade material is called rhenium-nickel alloy, rhenium and nickel are only rare elements in it. The main body is iron. During normal casting, the electromagnet is used to generate a strong directional magnetic field. The unsolidified superalloy is under the action of the directional magnetic field. Diffuse solidification in the same direction, and finally form a single crystal with all the molecules arranged exactly the same, so that the neatly arranged material can withstand high temperatures. This is the secret of single crystal superalloy manufacturing.
Everyone knows this method, but how strong is the magnetic field? How is the magnetic field placed? At what temperature does the magnetic field start? These are all accurate data that need to go through many experiments to obtain. If you don't find the right direction, you may not be able to break through for many years of research.
But now, in this technical data, various external environments have been clearly described. It can be said that it is simply a manufacturing process. As long as you follow this process, you can create a qualified product!
Of course, the premise is that the process is correct, and Professor Zhang can't wait.
With a daughter-in-law, I forgot my mother, and Professor Zhang, after obtaining these materials, he has forgotten the existence of Qin Guan and others, and wants to experiment immediately!
Therefore, Qin Guan could only laugh dryly: "Professor Zhang, remember what I said, after a while, you may be invited to the 4430 factory to use these technologies. Once qualified blades are manufactured, please notify me immediately."
I have to go back! It's another sleepless night!
Qin Guan couldn't help but think in his heart that he is simply an absolute model worker, but with so many things, he has to deal with it, especially the idea that I just thought of, I need to implement it step by step, and wait until I'm done. In May, everything is on track, so I can rest.
In the past few days, Qin Guan’s feelings are profound. He has seen some factories floating around, seeing some people’s pockets, and at the same time, seeing the hard work of the vast number of scientific and technological workers. It is their hard work that makes Han Han The country’s military industry is constantly becoming stronger!
In such a difficult environment, they quietly carried forward the enthusiasm of the older generation of scientific researchers. Compared with them, they are a little tired, and it is nothing.
Besides, I really didn't feel tired. It may be the reason that the system restarted. My mind is now much smoother.
When they returned, the sky was bright, and Qin Guan and his party could just bring a group of people from the two countries for breakfast.
"What is today's project?" Qin Guan asked Major Yang.
The dinner party last night seemed to make these people addicted to eating. This morning is much simpler. Millet porridge, wontons, fried dough sticks, tofu brains, and buns are these common ones.
Specially made some non-spicy foods for these foreigners. They are used to eating bread and ham, and they are very happy eating these things.
During the meal break, Qin Guan asked Major Yang. Now, although Major Yang is the chairman, he is actually fulfilling the role of Qin Guan's assistant very faithfully.
I've seen tanks and airplanes. What's next to fool the Chinese people?
There must be.
"After breakfast, we went to the nearby garrison to shoot a target and let them experience our 56 rush." ​​Major Yang said.
Hearing what Major Yang said, Qin Guan immediately gave a thumbs up, yes, how did he forget about it.
No matter how small the ant is, it is meat, light weapons. Although the profit of each item is not large, the advantage of light weapons lies in the large number!
For example, airplanes, even if they are a project, can be dozens of them, hundreds of them, and light weapons? Thousands of them are average, even tens of thousands or hundreds of thousands.
In the international arms market, the three enduring weapons are the AK47, the rocket launcher and the 107 rocket launcher.
Let me talk about the Ak47 first. In fact, everyone calls it that way. It is considered a habit. It is not widely circulated in the world, but its improved version, AKM.
A stands for automatic gun, K is the first letter of Kalashniv's name, so it can be called AK series.
AK47 was finalized in 1947, so it is called AK47. It began to be equipped with a large number of the bear country army in 49. This is the most reliable automatic rifle in the world. It is solid and durable, has low failure rate, reliable performance, simple structure and easy decomposition. Production costs are also very low.
However, this gun also has many small problems, so Kalashnikov also made many improvements to this gun, which was called AKM after the improvement.
There are many improvements. For example, the weight of the rifle is reduced, a large number of stamping parts are used, and the riveting is changed to welding. For example, the barrel section and tailstock are spot welded to a 1mm thick U-shaped receiver, and the frame-gun rail is also The stamping parts are spot-welded on the inner wall of the receiver; the magazine is changed to light alloy, which can be used with the original steel magazine. Later, a glass fiber plastic compression molded magazine was developed, which can also be fully used; , The handguard and the grip are made of synthetic resin materials.
Some documents explain that AKM uses folding buttstock. This M means folding buttstock. This is completely misunderstood. Folding buttstock is for certain units, such as infantry fighters, when riding in infantry fighting vehicles. Folding stocks are easy to shoot in the car. Normal troops still use fixed stock models.
The 56-stroke is the first time that Han has unified the complex domestic weapons and equipment after the founding of the country and became a gun clan.
