Chapter 197: The foundation of the sea of stars-materials

After giving these robots to Kuafu for his own management, Lei Tiantang came to the second floor of the basement. He wanted to make robots for experiments. Since most of the experimental equipment was on the second floor, he was on the second floor. A total of 300 humanoid robots and 150 other two robots were manufactured, and some tools and accessories were prepared.
There are 200 humanoid robots on the three underground floors, and 100 each of the other two robots. After Kuafu has completed their self-checks, they will start busy in the laboratory according to the procedures, and their performance is very good. The program is also an intelligent program designed by Kuafu, and they also form a network by themselves. The more robots in this network, the more intelligent they are.
Moreover, in the same network, they have a clear division of labor, and each cooperates tacitly, so what is displayed in Lei Tiantang’s eyes is an orderly work scene. Since Kuafu’s pre-installed intelligent programs already contain various equipment operation methods, So now they are operated separately in front of each device.
Sanitation doesn't need to be cleaned, because every time Lei Tian Tang comes, he will use the absolute domain to sweep once. The cleanliness of the entire space is enough to reach the laboratory use standard in a few seconds. Therefore, each of these robots turns on their devices for testing, and Kuafu is also paying attention to the testing of the devices online.
Lei Tiantang looked around with satisfaction and returned to his office on the second floor. Lei Tiantang installed a large number of high-definition screens. All the conditions of the entire laboratory can be seen here, because he is frantic. There are a large number of ultra-clear cameras installed in various places in the laboratory. These cameras can feed back the situation of the entire laboratory in real time. Of course, the cameras in the entire laboratory are also connected to Kuafu. .
When he comes to the office, he also has to consider what the laboratory should study first. Although it has been decided that the first thing to study is materials, there are more types of materials, such as metal materials, non-metal materials, composite materials, etc. Wait, which one to study first is what he wants to consider now.
Sitting in a chair and thinking about it, the first thing I decided was to continue to study the various high-performance materials required by the rocket engine, because this is related to the development of the Universe Technology Company, and he has been studying it for a period of time, and there are already some The result is that the materials used on the robot come from this, and I believe there will be results after a period of research.
Secondly, we must continue to study other types of high-performance batteries, and we should not hang ourselves on the graphene tree. Maybe batteries made from other methods and materials will perform better than graphene batteries? In the future, there will be more places to use high-performance batteries, so I will be prepared as early as possible so that I won’t be embarrassed.
The last thing I decided to study was the fuel, first the fuel for the rocket engine, and after the completion of this project, he had to consider the fuel for the spacecraft behind. He didn't have any idea about that fuel, so he could only do it step by step. Everyone knows the importance of rocket propellant fuel.
In terms of physical form, there are two forms of propellant used in rocket engines, one is a liquid substance and the other is a solid substance. Engines in which both the combustion agent and the oxidant are in liquid form are called liquid fuel engines, or liquid rocket engines.
Both are in a solid state and are called solid fuel rocket motors or solid rocket motors. Solid hydrogen and solid oxygen are used as rocket power.
If one of the two fuels is solid and the other is liquid, it is called a solid-liquid rocket motor or a rocket motor directly called its substance name. For example, a hydrogen-oxygen rocket engine.
Since the energy produced by the solid combustion agent is higher than the energy emitted by the liquid oxidant, most of the rocket engines developed are solid-liquid rocket engines. The two fuels meet and burn to form high-temperature and high-pressure gas. The gas is ejected from the nozzle and produces huge thrust. The launch vehicle was sent into space.
Commonly used propellants are:
1. Liquid hydrogen (fuel) and liquid oxygen (oxidant) have high combustion efficiency. It is mostly used in the final stage of space shuttles and carrier rockets. It is expensive and difficult to store.
2. Hydrazine-50 (fuel) dinitrogen tetroxide (oxidant), the combustion efficiency is average, it is mostly used in medium-sized rockets, the price is moderate, and it is easy to store.
3. RP-1 high-refined kerosene (fuel) liquid oxygen (oxidant) has average combustion efficiency. It is mostly used in the first stage of rockets. The price is moderate and difficult to store.
4. Hydrazine (fuel) and dinitrogen tetroxide (oxidant) have average combustion efficiency and are mostly used in satellites. They are prone to spontaneous combustion, relatively cheap, and highly corrosive.
The performance of these fuels is different, and because Lei Tiantang asked the people of Universe Technology to design a recyclable rocket like SpaceX's rocket, so the choice of fuel is very important. Because the rocket also requires a lot of fuel when it is recovered, this design will cause the rocket to be heavier when it takes off.
The take-off weight of the rocket is also related to the payload of the rocket, so if the fuel performance of the rocket is higher ~EbookFREE.me~ the fuel that needs to be carried will drop, so that the rocket can carry more payloads into the air , Can also greatly save costs.
So although there are already many fuel formulations, Lei Tiantang still wants to re-examine the fuel problem to see if he can get some breakthroughs in the formulation, so that his company’s rockets will have a great performance. The promotion.
Because the company’s early-stage space missions need to be completed by rockets, such as launching various exploration satellites, logging on to the moon, logging on to Mars, etc. Before the spacecraft is researched out, rockets are the only option, so Lei Tiantang told the company The rocket is still very important.
Of course, not only improving fuel efficiency can reduce the weight of the rocket, but other new materials can also reduce the weight of the rocket. If other high-strength structural materials are used elsewhere in the rocket, it can also reduce a lot of weight, such as While ensuring the strength of the material, by designing the interior of the material into a honeycomb or other shape, the weight of the rocket can also be significantly reduced.
These materials are all he needs to consider and research, and he also needs to conduct pre-study on the materials of future spacecraft. The environment in the universe is very complicated, and the performance requirements of the materials are higher. They must be protected from radiation, asteroid impact, etc. So it is not exaggerated to say that the basis of the stars and the sea is the material.
