Ma Yiming looked at Li Hao and Guo Jianzhuo. He organized his words carefully and explained why he was looking for high temperature resistant materials.

"The aerospace general-purpose engine we are developing is an engine that cannot be used by any aircraft in the world.

According to the performance of this engine, we have to redesign a space shuttle. "

When Ma Yiming said this, his tone paused. He was thinking in his heart: "I have never forgotten to create an ideal large aircraft. I tried every means to start the engine project, mainly to realize my dream of building an aircraft.

Originally, the research and development of the engine project was to think about the success of the engine project. The group will definitely spend huge sums of money to invest in the space shuttle project according to their ideas.

After all, so many resources have been invested in the early stage, it would be a pity to wait until the last step to give up.

But really get your hands dirty and start realizing your dreams. In reality, it encountered unimaginable difficulties.

Most of the difficulties were solved by cooperating with his old friend Niu Zhengfeng. Using the artificial intelligence scientific research software launched by the company - scientific research auxiliary system, it will be solved slowly.

Of course, the most difficult problem encountered was the solution given by the scientific research assistance system, but they were unable to use this solution.

The most important thing is that the current overall material technology is not good enough to support the realization of theoretical technology. "

Ma Yiming thought of this in an instant, and he continued: "We want to find high-temperature-resistant materials, mainly to solve the high-temperature friction between the surface materials of the aircraft and the atmosphere when the space shuttle enters and exits the atmosphere.

Now when launch vehicles and other aircraft fly out of the atmosphere, they are all coated with special materials on the surface of the rocket.

Through the melting and gasification of this material, a large amount of heat is absorbed in the process. The high temperature of about 3000 degrees will not cause the aircraft to burn down.

However, the materials used in launch vehicles are generally disposable, and they do not consider the high temperature generated when the materials are returned.

Even if there is a return-type launch vehicle, the speed of return is also very low, and the temperature generated is sufficient for the aircraft to withstand.

It is the space shuttle made in the United States in the past. Every time they use it, they need to install heat-insulating tiles on the surface of the aircraft. "

Hearing this, Li Hao interrupted Ma Yiming's narration, and asked curiously: "You are making rapid progress, and now you have already established a project to develop a space shuttle, I thought you have been exploring the engine.

During this period of time, there were many and urgent things, and I did not pay attention to the progress of your project.

I think thermal insulation tiles are a good idea, and our space shuttle can also use this method. Today's insulation tile technology should be much more advanced than decades ago. "

After Ma Yiming heard it, he immediately explained: "Thank you Mr. Li for your concern, the engine project is basically completed now, only the finishing stage is left.

We didn't think well when we started the engine project, because there is no aircraft in the world that can use our engine.

To make this engine work effectively, we must independently develop a supporting aircraft. "

When Li Hao heard this, he knew that he had fallen for the tricks often used by scientific researchers to cheat funding.

Some researchers are afraid that they will frighten their leaders by reporting too much funding. Using a sausage-cutting approach, they gradually report on the projects they need to research.

A lot of resources have been invested in the early stage, and the project has great hope of success. In order not to let the resources invested in the early stage go to waste, the leaders will definitely continue to invest.

Li Hao smiled when he thought of this. He also liked the establishment of the space shuttle program.

He agreed to the project approval of the engine, and he has already considered the development of supporting aircraft. Otherwise, Ma Yiming and the others wouldn't be so relaxed. When they first acted to entertain them, they found out the clues.

At that time, they will definitely be able to clearly understand artificial intelligence, the true degree of "intelligence".

Li Hao thought of this, smiled slightly, and continued to listen to Ma Yiming's report.

"We couldn't use the technology of insulating tiles on our space shuttle for two reasons.

A secondary reason is that this technique is cumbersome, requiring replacement of the insulating tiles on the surface of the aircraft after each use.

After a slight mistake, it will cause the consequences of aircraft crash and human death. This kind of technology with great safety hazards will never be adopted by our space shuttle project.

The most important reason is that the engine power we set is very powerful, and the speed of the space shuttle is very fast. The heat it generates is no longer able to compete with the insulation tile material.

At this speed, the ionized clouds produced by the space shuttle's friction with the atmosphere can not only isolate conventional electromagnetic communications, but also directly burn the insulation tile material. "

After Guo Jianzhuo heard what Ma Yiming said, he said with a smile: "It turns out that you are for this purpose, so you don't need to choose other materials at all, Yanjin is enough to deal with this kind of problem.

Sufficient preparation, not to mention the high temperature of about 3000 degrees, even the high temperature of about 8000 degrees can guarantee safety. "

Ma Yiming showed a startled expression, and asked very puzzled: "How is this possible, Director Guo, didn't you just say that the melting point of Yanjin is only about 1600 degrees. This is a temperature that has doubled the melting point. How is it possible?" continue to function at this high temperature."

Ma Yiming said with a smile: "You don't understand the properties of this material, so it's understandable to have such a misunderstanding.

You should have learned the simple physics experiment of boiling water in a paper pot in junior high school physics class.

Water and paper are burned together, due to heat conduction, the temperature of the paper will not exceed 100 degrees, because if it exceeds 100 degrees, the heat will be transferred to the water, and the heat will be transferred from the place with high temperature to the place with low temperature.

If only the paper is burned, the heat cannot be transferred to other places, and the temperature will rise to the ignition point of the paper, causing the paper to burn.

In the same way, the function of our flame gold material is only a bridge between two thermodynamic systems.

To use an inappropriate example as an example, the two thermodynamic systems are originally rugged mountain paths, and it takes a lot of effort for them to conduct heat.

With the participation of Yanjin, it is equivalent to building a high-speed rail between them. The heat transfer efficiency is greatly improved.

As long as the flame metal material is used as the outer shell of the aircraft, a circulating heat dissipation system is made inside the aircraft.

As long as the internal temperature of the Yanjin material does not rise to a height of about 1600°C, it will continue to function.

If the flame gold material cannot support the structure of your aircraft, you can also use the flame gold material by means of electroplating coating, but the cost will increase greatly. "

Hearing this, Ma Yiming said excitedly: "I am really grateful to Director Guo, the material you developed solved the major difficulties we encountered.

The problem of heat insulation of the outer shell of the space shuttle is one of the most troublesome problems for us. After this problem is solved, the space shuttle will enter the fast lane of research and development. "
