I have a little black hole

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

The next day he went to the materials company’s laboratory first, because it was too busy yesterday, and it was too late to wait, so he did not tell Zhao Junxian about his follow-up arrangements for the laboratory, especially the comprehensive laboratory The arrangement has never been said. Today he came to discuss the research direction of various materials with Zhao Junxian.

He arrived at the company at more than 9 o'clock, so the laboratory was already busy. For these experimenters, overtime is normal. So no one delayed because they went back to bed too late last night. Today's work time, of course, Zhao Junxian has already arrived.

Knowing that Lei Tiantang was here to discuss the laboratory arrangement 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?"

Lei Tiantang said with a smile: "Now the laboratory equipment has basically been 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. This time I came to you Discuss their work arrangements!"

After drinking tea, he continued: "You also know that our new company's current goal is to build and launch a rocket made by our company, and the first step is to target a medium-sized rocket. If you want to achieve this short-term goal, build a rocket Various materials are very important, especially the demand for high and low temperature resistant materials is very high, which requires us to conduct more in-depth research on existing materials!"

"Boss, you don't want all of these materials to be studied by the comprehensive laboratory? Then how come they are busy, to know that there are too many types of high and low temperature resistant materials needed on the rocket, they estimate in a laboratory Isn't it enough?" Zhao Junxian asked after thinking about it.

To know that a rocket has so many components, the materials of each component are not the same. Zhao Junxian has also paid attention to this information before.Rocket material 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 withstands the aerodynamic heating when it passes out of the atmosphere. Generally, the head fairing is made of metal or composite material, which requires the material to be resistant to high temperatures.

The second is the material of the projectile. The projectile of the rocket is mainly composed of an instrument compartment, a box, a transition section and a tail section.The parts other than the box body mainly play a structural supporting role, and are mostly made of high-strength aluminum alloy to make semi-hard shell structure or honeycomb structure.The materials here need to be high in strength and light in weight. Rockets are more critical of weight than aircraft, so materials in this area also need to be studied.

The third type of materials are engine materials. At present, 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 and high-density aluminum alloy castings or steel castings.These materials have to withstand the ultra-high temperature test, it can be said that the entire rocket has the highest material requirements.

The fourth type of materials are 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 fireproof putty, moisture-proof, mildew-proof and corrosion-resistant. Non-structural materials such as paints and coatings.

The last point is fuel. The fuel is nitrogen oxides: CO, H2, C2H2, CH4, C2H4, CH3CH2OH, N2H4, advanced borosilane (this is the fuel of the rocket thruster) and the ignition and principle of 2 kicks are almost the same. same.

It is certainly 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: "I'm not talking with you! How can I put all the work to the comprehensive laboratory, like those metal materials can be divided into a part of the metal laboratory, they are not so many people Maybe you should study stealth coatings? There are also non-metallic materials that can be divided into non-metal laboratories for them to study. Although the research of graphene is also very important, it cannot be studied in one laboratory. "

"Is it okay to give them the rest after dividing a part? Sort the things you want to study into categories, and then make a research plan. I won't teach you this point?"

"This arrangement is okay, but if so many types of material research are opened at once, our three laboratories will continue to expand, and the current staff seems to be insufficient, and research equipment will also need to be added! Many types of materials We still don't have the research equipment! When the laboratory started planning, it didn't consider this matter!" Zhao Junxian said a little embarrassed.

"I know, it's my fault, the goal I set for the company is too high, the pace is a bit big, the laboratory can't keep up with you, and it's still blamed for you. Buy anything! After consulting with the supervisors of several laboratories, you will report the equipment you need to purchase to the logistics department, let them continue to purchase, tell me how much money you need, and I continue to make additional investments 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 almost empty. Zhao Junxian also developed from the person in charge of the small laboratory at that time. Now, to manage such a huge laboratory, if his management level is indeed good, Lei Tiantang also wants to change people, and the company's development is indeed too fast. The people under him are a bit busy, but he can understand.

"This is no problem, boss, to be honest, it takes a lot of time to develop the company's laboratory to the level you need. It is not urgent to study this thing! We can only do our best after making plans Finish it!" Zhao Jun Xian said with a wry smile.

"I know there are a lot of tasks this time, but the problem is not as serious as you think! Now most of the materials needed on the rocket are still available on the market, although the performance may not be satisfactory. , But can also provide us with an idea.

Just like the stealth coating samples I provided, it is okay for us to learn from other people's research. During the research, you come to me when you encounter problems that cannot be solved. I believe I still have a way to solve your problems!"Lei Tiantang said with a smile.
