Chapter 122

After having supper with everyone, it was almost 12:30. The private residence above his private laboratory had not been decorated, so he still had to drive home to sleep.

The next day, he went to the laboratory of the materials company first. Because he was too busy yesterday and it was too late to finish the work, he didn't tell Zhao Junxian about the follow-up arrangement of the laboratory, especially the arrangement of the comprehensive laboratory. Today, he came to discuss the research direction of various materials with Zhao Junxian.

He arrived at the company more than 9 o'clock, so the laboratory has been busy for a long time. For these experimenters, working overtime is the most normal thing. Therefore, no one delayed today's work time because he went back to bed too late last night. Of course, Zhao Junxian also came long ago.

Knowing that Lei Tiantang was coming to discuss the arrangement of the laboratory with him, he took Lei Tiantang to his office in the laboratory and made tea for Lei Tiantang. After that, he asked, "boss, what specific arrangements do you have for the laboratory?"

Lei Tiantang said with a smile: "now the laboratory equipment is basically bought. Last time we talked about the arrangement of metal laboratory and non-metal laboratory, and there was no arrangement for comprehensive laboratory. This time I came to discuss their arrangement with you!"

After a sip of tea, he continued: "you know that the current goal of our new company is to build and launch rockets made by our company, and the first step is to build medium-sized rockets. If we want to achieve this short-term goal, it is very important to build various materials for rockets, especially the demand for materials that can withstand high and low temperatures is very large More in-depth research on existing materials! "

"Boss, you don't want the comprehensive laboratory to study all these materials, do you? How can they be so busy? You know, there are so many kinds of high and low temperature resistant materials needed on the rocket. They can't finish it in one laboratory, right Zhao Jun Xian thought and asked.

We should know that a rocket has so many components, and the materials of each part are different. Zhao Junxian also paid attention to this information before. Rocket materials can be divided into five parts.

The first is the warhead material. The head of the launch vehicle does not need to return to the ground. It only experiences the aerodynamic heating when it passes through the atmosphere. Generally, the head fairing is made of metal or composite materials, which requires the material to be resistant to high temperature.

The second is the material of missile body. The rocket body is mainly composed of instrument cabin, box, transition section and tail section. The part outside the box is mainly used to support the structure. The semi-rigid shell structure or honeycomb structure is made of high-strength aluminum alloy. Materials here need high strength and light weight. Rockets are more critical of their weight than airplanes. Therefore, materials in this area need to be studied.

The third kind of material is the engine material. Now the flying rocket basically uses liquid fuel. The liquid rocket engine is mainly composed of turbine, propellant pump and combustion chamber. The turbine materials are mainly nickel based and cobalt based alloys. The pump shell is made of aluminum alloy casting or steel casting with high strength and high density. These materials have to withstand the ultra-high temperature test, which can also be said to be the highest material requirements of the whole rocket.

The fourth kind of materials are non structural materials. The special working and storage environment of rockets and missiles requires the use of non structural materials such as high or low temperature resistant lubricating materials, vacuum sealing grease, high-grade hydraulic oil, inorganic compound fire-proof putty, moisture-proof, mould proof and corrosion-resistant paints and coatings.

The last point is fuel. The fuel is nitrogen oxides, such as CO, H2, C2H2, CH4, C2H4, CH3CH2OH, N2H4, and advanced borosilane (which are the fuel of rocket thrusters) and 2 kicks are almost the same in ignition and principle.

So many kinds of materials to a laboratory to complete, of course, it is impossible for Lei Tiantang to understand this, so he came to discuss with Zhao Junxian.

He shook his head with a smile and said, "I am not discussing with you! How can we put all the work to the comprehensive laboratory? For example, some of the metal materials can be divided into the metal laboratory, so many of them can't all study the stealth coating, right? And those non-metallic materials can also be assigned to non-metallic laboratories for them to study. Although graphene research is also very important, it can not be studied in all laboratories

"It's OK to give them all the rest after we divide them up? I don't have to teach you how to classify all the things you want to study, and then make a research plan. "

"This arrangement is OK, but if we open so many kinds of materials research at one time, our three laboratories will continue to expand. It seems that there are not enough personnel now, and the research equipment will also need to be added! We still don't have many kinds of equipment for material research! At the beginning of the laboratory planning, we did not consider this aspect of the matter! " Zhao Junxian said a little embarrassed.

"I know, it's my fault. The goal I set for the company is too high, and the pace is a little big. It's not your fault that the laboratory can't keep up with it. If you're short of manpower, you should continue to recruit. If the equipment is poor, you should buy it! You go to discuss with the supervisor of several laboratories and report the equipment to the logistics department, let them continue to purchase, tell me how much money is needed, I continue to make additional investment in the company! Don't worry about money! "Lei Tiantang also knew that his requirements for Zhao Junxian were too high. When he acquired Hongyuan new materials company, the company's laboratory was still in a state of almost nothing. Zhao Junxian also developed from the person in charge of the small laboratory at that time to managing such a large laboratory now. If his management level was not really good, Lei Tiantang would like to change people, and the development of the company was also correct It's too fast. The people under him are a little busy. He can understand.

"There will be no problem in this way, boss. To be honest, it will take a lot of time for the company's laboratory to develop to the level you need. It's hard to study this thing! We can only do our best to finish it after we have made a plan! " Zhao Junxian said with a bitter smile.

"I know there are many tasks this time, but the problem is not as serious as you think! At present, most of the materials needed by rockets can be bought in the market. Although the performance may not be satisfactory, it can also provide us with a way of thinking.

Just like the stealth coating samples I provided, we can learn from other people's research. When you encounter problems that cannot be solved, come to me. I believe I can still solve your problems! " Lei Tian Tang said with a smile.
