Chapter 340: Space Shuttle Program
Ma Yiming looked at Li Hao and Guo Jianhao, he carefully organized the language, and explained the reason why he was looking for high-temperature resistant materials.
"We are developing a universal aerospace engine, which is not available to any aircraft in the world today.
Based on the performance of this engine, we were going to redesign a space shuttle. ”
When Ma Yiming said this, his tone paused. He thought to himself, "I've never forgotten to build the ideal big plane." The main reason for starting the engine project in every possible way is to realize the dream of building an aircraft by itself.
Originally, the research and development of the engine project was to think that after the success of the engine project. The group will definitely follow their idea and invest heavily in the space shuttle project again.
After all, so many resources have been invested in the early stage, and it would be a pity to wait until the last step to give up.
But really get hands-on and start realizing your dreams. In reality, however, unimaginable difficulties were encountered.
Most of the difficulties came through the cooperation with his old friend Niu Zhengfeng. In the use of the company's artificial intelligence scientific research software - scientific research assistance system, it will be slowly solved.
Of course, the most difficult problem is the solution given by the research support system, but they cannot use this solution.
The most important thing is that the current overall material technology is not good and cannot support the realization of theoretical technology. ”
Ma Yiming thought of this for a moment, and he continued: "We want to find high-temperature resistant materials, mainly to solve the high-temperature friction between the surface material of the space shuttle and the atmosphere when it enters and exits the atmosphere.
Now launch vehicles and other vehicles fly out of the atmosphere, and they are coated with special materials on the surface of the rocket.
Through the melting and vaporization of this material, a large amount of heat is absorbed in the process. It will not let the high temperature of about 3000 degrees cause the aircraft to burn out.
But the materials used in launch vehicles are generally disposable, and they do not take into account the high temperatures generated when the materials are returned.
Even if there is a returnable launch vehicle, the speed at which it returns is also very low, and the temperature generated by the aircraft is enough to withstand it.
It was the space shuttle made in the United States in the past, and every time they used it, they needed to install heat insulation tiles on the surface of the aircraft. ”
When Li Hao heard this, he interrupted Ma Yiming's narration and asked curiously: "Your progress is very fast, and now you have established a project to develop the space shuttle, I thought you had been groping for the engine."
There were so many things going on during this time, and I didn't pay attention to the progress of your project.
I think insulating tiles are a great way to do it, and we can do that with our space shuttle. Thermal insulation tile technology should be much more advanced today than it was a few decades ago. ”
After Ma Yiming heard it, he immediately explained: "Thanks to Mr. Li's concern, the engine project is now basically completed, and only the finishing stage is left."
We didn't think it well when we started developing the engine project, after all, there is no aircraft in the world that can use our engines.
In order to make this engine effective, we must develop a matching aircraft independently. ”
When Li Hao heard this, he knew that he had fallen for the methods commonly used by scientific researchers to cheat funds.
Some researchers are afraid that they will be scared of the leaders by quoting too much funding. They use a sausage-slicing approach and report on the projects they need to work on, step by step.
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 to hear about the establishment of the space shuttle program.
He agreed to the establishment of the engine project, and he had already considered the development of supporting aircraft. Otherwise, Ma Yiming and they would not be so relaxed, and when they first acted, they found out the clues.
At that time, they will definitely be aware of artificial intelligence, the real "intelligence" level.
Thinking of this, Li Hao smiled slightly and continued to listen to Ma Yiming's report.
"There are two reasons why our space shuttles can't use thermal insulation tiles.
The secondary reason is that this technology is cumbersome, and the heat insulation tile on the surface of the aircraft needs to be replaced after each use.
The slightest mistake will lead to the destruction of the plane and the death of people. This kind of technology, which has great safety risks, will never be adopted in our space shuttle program.
The most important reason is that the engines we set are very powerful, and the shuttle is very fast. The heat it generates is no longer something that the insulation tile material can compete with.
At this speed, the ionized clouds produced by the friction between the space shuttle and the atmosphere can not only isolate conventional electromagnetic communications, but also directly burn the insulation tile material. ”
After Guo Jianmiao heard Ma Yiming's story, he said with a smile: "You are originally using this purpose, so you don't need to choose other materials at all, Yanjin is enough to deal with this kind of problem."
Be well prepared, not to mention a high temperature of about 3000 degrees, even a high temperature of about 8000 degrees can ensure safety. ”
Ma Yiming showed a stunned expression and asked puzzledly: "How is this possible, Director Guo, didn't you say just now that the melting point of Yanjin is only about 1600 degrees." That's twice the temperature of the melting point. How is it possible that it will continue to function at such high temperatures. ”
Ma Yiming said with a smile: "You don't understand the characteristics of this material, and it is understandable that there is such a misunderstanding."
You should have learned about boiling water in a paper pot in your junior high school physics class, this simple physics experiment.
Water and paper are burned together, and the temperature of the paper will not exceed 100 degrees due to the conduction of heat, because if it exceeds, the heat is transferred to the water, and the heat is transferred from the place with high temperature to the place with low temperature.
If you only burn the paper, the heat cannot be transferred anywhere else, and the temperature will rise all the way to the ignition point of the paper, causing the paper to burn.
In the same way, our Yanjin material only plays a role as a bridge between two thermodynamic systems.
To use a less appropriate example, two thermodynamic systems are originally rugged mountain paths, and it takes a lot of effort for them to conduct heat.
With Yanjin's participation, it is equivalent to building a high-speed rail between them. The efficiency of heat transfer is greatly improved.
As long as the flame gold material is used as the shell of the aircraft, a circulating heat dissipation system is made inside the aircraft.
As long as the internal temperature of the material does not rise to about 1600°C, it will continue to function.
If the Yanjin material cannot support the structure of your aircraft, you can also use the Yanjin material by electroplating and other methods, but the cost will increase greatly. ”
When Ma Yiming heard this, he said excitedly: "Thank you so much Director Guo, this material you developed has solved the major difficulties we encountered."
The problem of thermal insulation of the outer shell of the space shuttle is one of the most troublesome problems for us, and after this problem is solved, the space shuttle enters the fast lane of research and development. ”
