I have a little black hole

After handing over these robots to Kuafu himself, Lei Tiantang came to the second floor underground. He was going 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 two other 150 robots were manufactured, and some tools and accessories were prepared.

On the third basement floor, there are 200 humanoid robots and 100 other two robots. After the self-checking by Kuafu's operation is completed, they start to busy themselves in the laboratory according to the procedure, and their performance is very good. The programs are also intelligent programs 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 cooperate with each other, so what Lei Tiantang sees is an orderly work scene. Since the intelligent program pre-installed by Kuafu already contains the operation methods of various devices, So now they operate separately in front of each device.

Hygiene does not need to be cleaned, because every time Lei Tiantang comes, he will use the absolute field to scan once, and the cleanliness of the entire space in a few seconds is enough to meet the standard of laboratory use.So these robots all open their devices for testing, and Kuafu also pays attention to the detection of devices online.

Lei Tiantang looked around with satisfaction and returned to his office on the second floor, where Lei Tiantang was equipped with a large number of high-definition screens. All the conditions in the entire laboratory can be seen here because he was mad and mad A large number of ultra-clear cameras are installed in various places in the laboratory. These cameras can feed back 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 must also consider what the laboratory should study first. Although it has long been decided that the first thing to be studied is the material, but there are more types of materials, metallic materials, non-metallic materials, composite materials, etc. Wait, what kind of research should he consider first.

Sitting in a chair and thinking about it, the first decision 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 also been researching for a while, and already has some As a result, the materials used on the robot are like this. 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 should not hang on the graphene tree. Could the batteries made by other methods and materials have better performance than graphene batteries?There will be more places to use high-performance batteries in the future, and preparations will not be held until the time comes.

The final decision was to study the fuel, first the fuel of the rocket engine. After the project is completed, the fuel of the spaceship behind will also be considered. Now that fuel has no clue, he can only come step by step.Everyone knows the importance of rocket propellant fuel.

Physically speaking, the propellant used by the rocket engine comes in two forms, 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 engines or solid rocket engines.Solid hydrogen and solid oxygen are used as rocket power.

If, of the two fuels, one is solid and the other is liquid, it is called a solid-liquid rocket engine or a rocket engine whose substance name is directly called.For example, oxyhydrogen rocket engines.

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 a high temperature and high pressure gas. The gas is ejected from the nozzle and generates a huge thrust. Put the launch vehicle into space.

Commonly used propellants are:

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

2. Hydrazine-50 (fuel) dinitrogen tetroxide (oxidant), the combustion efficiency is general, mostly used in medium-sized rockets, the price is moderate, and it is easy to store.

3. RP-1 highly refined kerosene (fuel) liquid oxygen (oxidant), the combustion efficiency is general, mostly used in the first stage of the rocket, the price is moderate, and it is not easy to store.

4. Hydrazine (fuel) and dinitrogen tetroxide (oxidant), the combustion efficiency is general, mostly used in satellites, easy to spontaneous combustion, the price is relatively cheap, and extremely corrosive.

The performance of these fuels is different, and because Lei Tiantang asked the people of Universe Technology to design the same rockets as SpaceX with recyclable rockets, the choice of fuel is very important.Because the rocket also needs a lot of fuel when it is recycled, this design will cause the rocket to weigh more when it takes off.

The rocket's take-off weight is also related to the rocket's payload, so if the rocket's fuel performance is higher, the fuel that needs to be carried will drop, so that the rocket can carry more payload to the air, and it can also greatly save cost.

So although there are many kinds of fuel formulas now, the fuel problem Lei Tiantang still wants to re-examine himself to see if he can get some breakthroughs in the formula, so that his company’s rocket will have a great performance Promotion.

Because the company’s early space missions all require rockets to complete, such as launching various exploration satellites, logging on the moon, and logging on Mars, etc. Before the spacecraft was researched, the rocket was the only choice, so Lei Tiantang was against the company. The Rockets still take it very seriously.

Of course, not only can improving fuel efficiency reduce the weight of the rocket, 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 in While ensuring the strength of the material, the interior of the material is designed into a honeycomb or other shape to design, the weight of the rocket can also be significantly reduced.

These materials are also what he needs to consider and study, and he needs to study the materials of the future spacecraft in advance. The environment in the universe is very complicated, and the performance of the materials is higher. Therefore, it is not an exaggeration to say that the basis of the starry sea is the material.
