I Have a Little Black Hole

After handing over these robots to Kuafu himself, Lei Tiantang came to the second underground floor. 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 of the other two types of robots were built, and some tools and accessories were prepared.

There are 200 humanoid robots on the third underground floor, and 100 of the other two robots. After Kuafu completed their self-check, they started to work in the laboratory according to the program, and their performance was very good. , the program is also an intelligent program designed by Kuafu, and they also form a network by themselves. The more the number of robots in this network, the higher the intelligence.

And in the same network, they have a clear division of labor, and they cooperate with each other tacitly, so what Lei Tiantang sees is an orderly work scene. Because Kuafu's pre-installed smart programs already contain the operation methods of various devices, So now they operate separately in front of each device.

There is no need to clean up the hygiene, because every time Lei Tiantang comes, he will use the absolute field to sweep it once, and the cleanliness of the entire space in a few seconds is enough to meet the standard of use in the laboratory. Therefore, these robots open the equipment for testing, and Kuafu is also paying attention to the testing of the equipment 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 here. All the situation in the entire laboratory can be seen here, because he is crazy. A large number of ultra-clear cameras are 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 came to the office, he also wanted to think about what the laboratory should study first. Although he had already decided that the first study was materials, there were many 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 decision was to continue researching various high-performance materials required by rocket engines, because this is related to the development of the space technology company, and he has been researching for a while before, and already has some As a result, the materials used in the robot come from this way. I believe that after a period of research, there will be results.

Secondly, we must continue to study other types of high-performance batteries, and we must not hang ourselves on the tree of graphene. Maybe batteries made by other methods and materials will perform better than graphene batteries? There will be many places to use high-performance batteries in the future, and you will not be crammed when you prepare early.

In the end, he decided to study the fuel. First, the fuel of the rocket engine. After the project was completed, he had to consider the fuel of the spaceship behind. He didn't have any clues about that fuel, so now he can only come step by step. Everyone knows the importance of rocket propellant fuel.

Physically speaking,

The propellants used in rocket motors come in two forms, one is a liquid substance and the other is a solid substance. An engine in which both the combustion agent and the oxidant are in liquid form is called a liquid fuel engine, or a liquid rocket engine.

Both are in a solid state and are called solid fuel rocket motors or solid rocket motors. Solid hydrogen, solid oxygen, as rocket power.

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

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

Common propellants are:

1. Liquid hydrogen (fuel) and liquid oxygen (oxidant) have high combustion efficiency and are mostly used in the final stage of space shuttles and launch vehicles, which are expensive and difficult to store.

2. Hydrazine-50 (fuel) nitrous oxide (oxidant), with average combustion efficiency, mostly used in medium-sized rockets, moderately priced and easy to store.

3. RP-1 highly refined kerosene (fuel) liquid oxygen (oxidant), with average combustion efficiency, mostly used in the first stage of rockets, moderate price and difficult to store.

4. Hydrazine (fuel), nitrous oxide (oxidant), general combustion efficiency, mostly used in satellites, easy to spontaneous combustion, relatively cheap, and extremely corrosive.

The properties of these fuels vary, and since Lei Tiantang asked the cosmic technology company to design a rocket that uses the same recyclable rocket as SpaceX's rocket, the choice of fuel is important. Because the rocket also needs a lot of fuel when it is recovered, this design will cause the rocket to weigh more 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 decrease, so that the rocket can be lifted off with more payload, and it can also save a lot. cost.

Therefore, although there are already many fuel formulas, 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 rocket will be greatly improved. improvement.

Because the company's various space missions in the early stage need to be completed with rockets, such as launching various exploration satellites, landing on the moon, landing on Mars and other tasks, before the spacecraft is researched, rockets are the only choice, so Lei Tiantang told the company. The rocket is still very important.

Of course, not only can improving the fuel efficiency 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 in other parts of the rocket, it can also reduce a lot of weight, such as in While ensuring the strength of the material, the interior of the material is designed in a honeycomb or other shape, and the weight of the rocket can also be significantly reduced.

These materials are also what he needs to consider and study, and he also needs to conduct pre-research on the materials of future spacecraft. The environment in the universe is very complex, and the performance requirements of materials are higher, such as radiation protection, asteroid impact prevention, etc. , so it is no exaggeration to say that the foundation of the sea of ​​stars is the material.
