I Have a Little Black Hole

It was almost 12:30 after eating supper with everyone. 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 laboratory of the material company first, because yesterday was too busy, and it was too late when the work was over, 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, and today he is mainly to discuss with Zhao Junxian the research direction of various materials.

It was after 9 o'clock when he arrived at the company, so the laboratory was already busy. For these experimenters, it was normal to work overtime, so no one was delayed because they went back to bed too late last night. Today's work hours, of course, Zhao Junxian came early.

Knowing that Lei Tiantang was here to discuss the arrangement of the laboratory with him, he brought 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 equipment for the laboratory 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 am here with you. Discuss their arrangements!

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

Boss, don't you want the comprehensive laboratory to study all these materials? Then why are they so busy? You must know that there are too many types of high and low temperature resistant materials needed on rockets. One of their laboratories estimated that Is it impossible to finish? Zhao Junxian asked after thinking for a while.

You must know that a rocket is made up of so many parts, and the materials of each part are different. Zhao Junxian has also paid attention to this information before. The material of the rocket can be basically divided into 5 parts.

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

The second is the material of the projectile. The projectile of the rocket is mainly composed of the instrument cabin, the box, the transition section and the tail section. The part other than the box mainly plays the role of structural support, and is mostly made of high-strength aluminum alloy to make a semi-monocoque structure or a honeycomb structure. The materials here need high strength and light weight. Rockets are more picky about weight than airplanes, so materials in this area also need to be studied.

The third type of material is the engine material. Now flying rockets basically use liquid fuel. The liquid rocket engine is mainly composed of a turbine, a propellant delivery pump and a combustion chamber. Turbine materials are mainly nickel-based, cobalt-based alloys. The pump casing is made of high-strength, high-density aluminum alloy castings or steel castings. These materials have to withstand the test of ultra-high temperature, and it can be said that the entire rocket has the highest requirements for materials.

The fourth category of materials are non-structural materials, special working and storage environments for rockets and missiles, and require the use of lubricating materials such as high temperature or low temperature resistant lubricating materials, vacuum sealing grease, advanced 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 (this is the fuel for rocket thrusters) and 2 kicks. The ignition and principle are similar Same.

Of course, it is impossible for so many kinds of materials to be handed over to a laboratory. Lei Tiantang also understands this, so he came to discuss with Zhao Junxian.

He smiled and shook his head: I'm not discussing with you! How could it be possible to push all the work to the comprehensive laboratory, like those metal materials can be divided into a part of the metal laboratory, so many of them do not Maybe all of them will study stealth coatings? There are also non-metallic materials that can be assigned to non-metallic laboratories for them to study. Although graphene research is also very important, it cannot be studied in all laboratories.

It's alright to leave the rest to them for research after dividing up a part of it, right? Classify all the things to be researched, and then formulate a research plan. I don't need to teach you about this, right?

This arrangement is fine, but if we open so many types of materials research at once, our three laboratories will continue to expand. It seems that the current personnel are not enough, and research equipment will also need to be added! Many types of materials We still don't have the equipment for research! When the laboratory first started planning, we didn't consider this aspect! Zhao Junxian said with a little embarrassment.

I know, it's my fault. I set the company's goals too high, and the pace is a little big. It's not your fault that the lab can't keep up. Again, if you don't have enough staff, keep recruiting. The equipment is poor. Buy whatever you want! After discussing it with the supervisors of several laboratories, report the equipment to be purchased to the logistics department, let them continue to purchase, and tell me how much money is needed, and I will 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 head of the small laboratory at that time to Now to manage such a huge laboratory, if his management level is really good, Lei Tiantang also wants to change people, and the company's development is indeed too fast, and he can understand that the people under him are a little busy.

There's 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, and there is no rush to study this thing! We can only try 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! Most of the various materials needed for rockets are still available in the market, although the performance may not be satisfactory. , but it can also give us an idea.

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