Chapter 198

After leaving all these robots to Kuafu for his own management, Lei Tiantang came to the second floor of the underground. He wanted to make robots for experiments. Since most of the experimental equipment is on the second floor, he has made 300 humanoid robots and 150 other robots in the second floor, and has prepared some tools and accessories.

On the third floor, there are 200 humanoid robots and 100 other robots. After Kuafu operates them, they start to be busy in the laboratory according to the procedures. Their own performance is very good. The program is also an intelligent program designed by Kuafu. Moreover, they also form a network of their own, in which the more robots there are The higher the intelligence.

Moreover, in the same network, their division of labor is clear and their cooperation is tacit. Therefore, what Lei Tiantang sees is an orderly working scene. As Kuafu's pre installed intelligent program already contains the operation methods of various devices, they now operate separately in front of each device.

There is no need to clean the room, because every time Lei Tiantang comes, he will use the absolute field to sweep once. In a few seconds, the cleanliness of the whole space is enough to meet the use standard of the laboratory. Therefore, these robots open their own devices for detection, and Kuafu also pays attention to the detection of the devices online.

Lei Tiantang was satisfied to observe around and then returned to his office on the second floor. There were a large number of high-definition screens installed by Lei Tiantang. All the conditions of the whole laboratory can be seen here, because he was so crazy that he installed a large number of ultra clear cameras in all parts of the laboratory. These cameras can real-time monitor the situation of the whole laboratory Feedback here, of course, the entire laboratory camera is also connected with Kuafu.

When he came to the office, he also had to consider what the laboratory should study first. Although he had already decided that the first thing to study was materials, there were many kinds of materials, such as metallic materials, non-metallic materials, composite materials, etc. which one should be studied first is what he should consider now.

Sitting in a chair and considering it for a while, the first decision is to continue to study various high-performance materials needed by rocket engines, because this is related to the development of cosmos technology company. Moreover, he has studied it for a period of time and has already made some achievements. This is the way the materials used in robots come from. I believe that the results will be obtained after a period of research.

Secondly, we should continue to study other types of high-performance batteries, and we should not hang on the graphene tree. Maybe the performance of batteries made by other methods and materials will be better than that of graphene batteries? In the future, there are more places to use high-performance batteries. You should prepare early, so that you won't cram at the moment.

Finally, he decided to study the fuel, first of all, rocket engine fuel. After the completion of this project, he also had to consider the fuel of the later spaceship. At present, he did not have any clue about the fuel, so he could only do it step by step. We all know the importance of rocket propellant fuel.

Physically speaking, there are two kinds of propellant used in rocket engine, one is liquid substance, the other is solid material. Combustion agent and oxidant are both in the form of liquid, so it is called liquid fuel engine, or liquid rocket engine.

Both are in solid state, it is called solid fuel rocket motor or solid rocket motor. Solid hydrogen, solid oxygen, as rocket power.

If one of the two fuels is a solid and the other is a liquid, it is called a solid-liquid rocket motor or a rocket motor directly called its substance name. For example, hydrogen oxygen rocket engine.

Since the energy produced by solid combustion agent is higher than that from liquid oxidant, most of the rocket engines developed are solid-liquid rocket engines. The two fuels meet and burn, forming high-temperature and high-pressure gas. The gas is ejected from the nozzle, which generates huge thrust and sends the carrier rocket into space.

The commonly used propellants are:

1. Liquid hydrogen (fuel) and liquid oxygen (oxidant), with high combustion efficiency, are mostly used in the last stage of space shuttle and launch vehicle, which are expensive and difficult to store.

2. Hydrazine-50 (fuel) nitrogen tetroxide (oxidant) has general combustion efficiency. It is mostly used in medium-sized rockets, with moderate price and easy storage.

3. RP-1 is highly refined kerosene (fuel) and liquid oxygen (oxidant) with general combustion efficiency. It is mostly used in the first stage of rocket, with moderate price and difficult storage.

4. Hydrazine (fuel) and nitrogen tetroxide (oxidant) have general combustion efficiency and are mostly used in satellites. They are easy to spontaneous combustion, relatively cheap and highly corrosive.

The performance of these fuels is different, and since Lei Tiantang asked the people of cosmos technology company to design the same recyclable rocket as SpaceX's, the choice of fuel is very important. Because the rocket needs a lot of fuel when it is recycled, this design will make the rocket 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, the fuel that needs to be carried will be reduced, so that the rocket can carry more payloads and can greatly save the cost.Therefore, although there are many kinds of fuel formulations, Lei Tiantang still wants to re study the fuel problem to see if he can make some breakthroughs in the formula, so that the performance of his company's rockets will be greatly improved.

Because the company's early space missions need to be completed by rockets, such as launching various exploration satellites, landing on the moon, landing on Mars and other missions. Before the spaceship is developed, rockets are the only choice, so Lei Tiantang still attaches great importance to the company's rockets.

Of course, not only improving fuel efficiency can reduce the weight of the rocket, but also other new materials can reduce the weight of the rocket. If other high-strength structural materials are used in other parts of the rocket, it can also reduce a lot of weight. For example, while ensuring the strength of the material, the interior of the material is designed into honeycomb or other shapes to design fire The weight of the arrow can also be significantly reduced.

These materials also need to be considered and studied by him, and the materials of future spaceships should be studied in advance. The environment in the universe is very complex, and the performance of materials is required to be higher. It is not exaggerating to say that the foundation of the star sea is materials.
