Chapter 122: Research arrangements for rocket materials

　　 After eating supper with everyone, it was almost 12:30. The private residence above his private laboratory has not been decorated yet, so he still has to drive home to sleep.
The next day, he went to the materials company's laboratory first. Because yesterday was too busy and it was too late when it was finished, he did not tell Zhao Junxian about his follow-up arrangements for the laboratory, especially the comprehensive laboratory. He never said that he came here today to discuss the research directions of various materials with Zhao Junxian.
It was past 9 o’clock when he arrived at the company, so the laboratory was already busy. For these experimenters, working overtime was normal, so no one was delayed because he went back to bed late last night. Of course, Zhao Junxian had already arrived at work today.
Knowing that Lei Tiantang was here to discuss laboratory arrangements with him, he took Lei Tiantang to his office in the laboratory, and after making tea for Lei Tiantang, he asked: "Boss, experiment What are your specific arrangements for the room?"
Lei Tiantang said with a smile: "Now the equipment in the laboratory is basically bought. Last time we talked about the arrangement of the metal laboratory and the non-metal laboratory, and there is no arrangement for the comprehensive laboratory. Discuss their work arrangements!"
After a sip of tea, he continued:
You also know that our new company’s current goal is to build and launch our own-made rockets, and the first goal is medium-sized rockets. If you want to achieve this short-term goal, build rockets. All kinds of materials are very important, especially for the types of materials that can withstand high and low temperatures, which requires us to conduct more in-depth research on existing materials!"
"Boss, don't you want to let the comprehensive laboratory study all these materials? Then why are they so busy? You have to know that there are too many types of high and low temperature resistant materials needed on the rocket, and their laboratory estimates You can't finish it, right?" Zhao Junxian thought for a while and wanted to ask.
　　 You must know that a rocket has so many components, and the materials of each component are different. Zhao Junxian has also paid attention to this aspect of information before. The material of the rocket can basically be divided into 5 parts.
　　 The first is the warhead material. The head of the launch vehicle does not need to return to the ground, but only undergoes aerodynamic heating when it penetrates the atmosphere. Generally, the head fairing is made of metal or composite materials, which requires the material to withstand high temperatures.
　　 The second is the material of the missile body. The rocket body is mainly composed of the instrument bay, the box body, the transition section and the tail section. The parts other than the box are mainly used for structural support, and high-strength aluminum alloys are mostly used to make semi-monocoque structure or honeycomb structure. The materials here need high strength and light weight, and rockets are more critical of weight than airplanes, so materials in this area also need to be studied.
　　 The third type of material is engine materials. Now flying rockets basically use liquid fuel. Liquid rocket engines are mainly composed of turbines, propellant delivery pumps and combustion chambers. Turbine materials are mainly nickel-based and cobalt-based alloys. The pump casing adopts high-strength, high-density aluminum alloy castings or steel castings. These materials have to withstand the test of ultra-high temperature, which can also be said to be the highest requirement for materials in the entire rocket.
The fourth type of material is non-structural materials. The special working environment and storage environment of rockets and missiles require the use of high-temperature or low-temperature resistant lubricating materials, vacuum sealing grease, high-grade hydraulic oil, inorganic compound fire-proof putty, moisture-proof, mildew-proof and corrosion-proof Non-structural materials such as paints and coatings.
The last point is the fuel. The fuel is nitrogen oxides: CO, H2, C2H2, CH4, C2H4, CH3CH2OH, N2H4, high-grade borosilane (the fuel for rocket propulsion) and the same ignition principle as the 2 kicker. same.
　　 Of course, it is impossible for so many kinds of materials to be completed by a laboratory. Lei Tiantang also understands this, so he came to discuss with Zhao Junxian.
He smiled and shook his head and said: "I'm not discussing with you! How can it be possible to transfer all the work to the comprehensive laboratory, like those metal materials can be divided into parts of the metal laboratory, so many people do not Maybe we should all study stealth coatings, right? Those non-metallic materials can also be assigned to non-metallic laboratories for their research. Although graphene research is also very important, it cannot be studied in a single laboratory. "
　　 "After dividing a part, let them study the rest, right? Classify all the things to be studied, and then make a research plan. I don't need to teach you this, right?"
"This arrangement is fine, but if we start research on so many types of materials at once, our three laboratories will continue to expand. The current staff seems to be insufficient, and research equipment will be added! Many types of materials We still don’t have the equipment for the research! We didn’t think about this when the laboratory was first planned!" Zhao Junxian said embarrassedly~EbookFREE.me~ I know, this is my fault , The goal I set for the company is too high, and the steps are a bit big. I don’t blame you if the laboratory can’t keep up. If you don’t have enough staff, then continue to recruit, and buy if the equipment is poor! After discussing with the supervisors of several laboratories, you will report the equipment you need to purchase to the logistics department so that they can continue to purchase and tell me how much money is needed. I will continue to invest 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, the company's laboratory was still in a state of almost nothing. Zhao Junxian also developed from being a small laboratory person in charge at that time. Now to manage such a huge laboratory, if it were not for his good management level, Lei Tiantang would also want to change people, and the company's development is indeed too fast, and he can understand that the people under his staff are a bit busy.
"There will be no problem, boss, to be honest, it takes a lot of time for the company laboratory to develop to the level you need. It is not anxious to study this thing! We can only do our best after making a plan. Finish it!" Zhao Junxian said with a wry smile.
"I know there are many missions this time, but the problem is not as serious as you think! Now most of the materials needed on the rocket are still available in the market, although the performance may not be satisfactory. , But it can also provide us with an idea.
　　 Just like the stealth coating samples I provided, we can learn from other people's research. During the research, if you encounter problems that cannot be solved, come to me. I believe I still have a way to solve your problems! "Lei Tiantang said with a smile.
