Ma Yiming looked at Li Hao and Guo Jianyu, he carefully organized the language, and explained why he was looking for high temperature resistant materials.

"The aerospace and aviation general motive we are studying is a motive that cannot be used by any aircraft in the world today.

Based on the performance of this motivation, we will redesign a space shuttle. "

When Ma Yiming said here, he paused. He thought to himself: "I have never forgotten to make the ideal large aircraft. Every attempt to start a motivational project is mainly to realize my dream of making an aircraft.

The motivation project was originally designed after the success of the motivation project. The group will definitely invest huge sums of money into the space shuttle project according to their ideas.

After all, so many resources have been invested in the early stage, it is a pity to wait until the last step before giving up.

But I really started to realize my dream. In reality, we have encountered unimaginable difficulties.

Most of the difficulties are through the cooperation with his old friend Niu Zhengfeng. The use of artificial intelligence research software launched by the company-scientific research assistance system, will be resolved slowly.

Of course, the most difficult problem encountered was the solution provided by the scientific research assistance system, but they could not use this solution.

The most critical thing is that the current overall material technology is not working and cannot support the realization of theoretical technology. "

Immediately thinking of this, Ma Yiming continued: "We want to find high temperature resistant materials, mainly to solve the high temperature friction between the surface material of the aircraft and the atmosphere when the shuttle enters and exits the atmosphere.

Now launch vehicles such as carrier rockets 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. It will not let the aircraft burn down due to the high temperature of about 3ooo degrees.

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

Even if there is a return carrier rocket, the degree of return is very low, and the temperature of the aircraft is sufficient to withstand it.

It was the space shuttle made by the United States in the past. Every time they used it, they needed to install insulation tiles on the surface of the aircraft. "

When Li Hao heard this, he interrupted Ma Yiming's remarks and asked curiously: "Your progress is very fast. Now that you have set up a research space shuttle, I thought you have been exploring the motivation.

During this period of time, there were so many and urgent things that I didn't pay attention to the progress of your project.

I think insulation tiles are a good way, 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: "Thanks to President Li for his concern, the motivation project is now basically completed, and only the closing stage is left.

We didn't think about it when we started the motivation project. After all, no aircraft in the world can use our motivation.

In order for this motivation to be effective, we must independently develop a matching aircraft. "

When Li Hao heard this, he knew that he had been employed by scientific researchers to cheat funds.

Some researchers are afraid that too much funding will scare leaders. They use a sausage-style approach to report on the items they need to study.

A lot of resources have been invested in the early stage, and the project has great hopes for success. In order to prevent the resources invested in the early stage from drifting, leaders will certainly continue to invest.

Li Hao smiled when he thought about it. He also liked to see the Space Shuttle project set up.

He agreed with the motivation of the project and already considered the research and development of the aircraft. Otherwise, Ma Yiming will not be so relaxed, and when they entertained them, they started to show up.

At that time, they must be soberly aware of the true "intelligence" of artificial intelligence.

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

"Our space shuttle cannot use the technology of thermal insulation tiles for two reasons.

The secondary reason is that this technique is cumbersome, and the insulation tiles on the aircraft surface need to be replaced after each use.

After a few mistakes, the consequences of machine death will be caused. This technology with great safety hazards will never be adopted by our space shuttle project.

The most important reason is that the power we set is very high, and the shuttle is very fast. The heat it generates is no longer counterbalanced by the insulation tile material.

At this degree, the space shuttle's ionizing clouds caused by friction with the atmosphere can not only isolate conventional electromagnetic communication, but also directly burn the insulation tile material. "

After Guo Jianming heard Ma Yiming's remarks, he said with a smile: "You originally used this purpose, so you don't need to choose other materials at all, Yan Jin is enough to deal with this kind of problem.

Prepare well, not to mention the high temperature of about 3ooo degree, even the high temperature of about 8ooo degree can also ensure safety. "

Ma Yiming showed a startled expression and asked puzzledly: "How is this possible, Director Guo, you just said that the melting point of Yan Jin is only about 16oo degrees. This is a temperature that is double the melting point. How can it Continue to work at these high temperatures. "

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

You should have studied paper pot boiling water in junior high school physics class, this simple physics experiment.

Water and paper are burned together. Due to the heat conduction, the temperature of the paper will not exceed 1oo degree, because if it passes, the heat is transferred to the water, and the heat is transferred from the high temperature place to the low temperature place.

If only the paper is burned, the heat cannot be transmitted elsewhere, and the temperature will rise to the paper's ignition point, causing the paper to burn.

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

Take a less appropriate example. The two thermodynamic systems were rugged mountain paths, and their heat transfer was very laborious.

With Yanjin's participation, it is equivalent to build a high-speed rail between them. The heat transfer efficiency has been greatly improved.

As long as the flame gold material is used as the outer shell of the aircraft ~ www.readwn.com ~, a cyclic cooling system should be prepared inside the aircraft.

As long as the internal temperature of the Yanjin material does not rise by about 16ooc, it will continue to work.

If Yanjin materials cannot support the structure of your aircraft, you can also use Yanjin materials such as electroplating coating, but the cost will increase significantly. "

When Ma Yiming heard this, he said excitedly: "This is really thanks to Director Guo. The material you researched has solved the major difficulties we encountered.

One of the most difficult problems that trouble us is the thermal insulation of the shuttle's shell. After this problem is solved, the shuttle will enter the fast lane of research. "
