Chapter 357: Space shuttle shell

Ma Yiming immediately came to the spirit. This is the result of Li Hao's recent investigation.
Today is really his lucky day, this day is really the most suitable choice.
Now major breakthroughs have been made in space projects. Just lead Li Hao to look at the effect and show their ability through specific examples. This is one of the best ways to show ability.
Ma Yiming immediately said respectfully: "It is a coincidence that President Li has come here. We are constantly verifying that the outer shell of the space shuttle can meet our goals.
Now basically successful, preparations are being made for extreme testing of the shuttle's enclosure. Let's take a look at this experiment. "
Li Hao immediately nodded in agreement: "Your movements are so fast. I did not expect that the shuttle shell would be made.
I know that the technical standards required for the shuttle's enclosure are very high, and he doesn't just want to ensure that they are intact in the atmosphere.
It is also necessary to prevent the exposure of small and medium-sized meteorites and high-intensity cosmic radiation. After all, the space shuttle we studied was not playing around in the outer orbit of the earth.
He wanted to go deep into the solar system for long-distance navigation. "
Li Hao said that the space shuttle was sailing in the solar system, and he remembered whether the space shuttle could travel long distances. The most critical piece of equipment was whether its engine could meet the requirements.
You need to know that many of China's equipment can be produced by itself, but the engine is generally not.
As they walked into the laboratory, Li Hao asked Niu Zhengfeng: "Niu Gong, how are the engines supporting the space shuttle progressing?"
Niu Zhengfeng said confidently: "For the engine project, President Li does not need to worry. We will definitely complete the project on time.
The engine has now been basically designed and is undergoing long-term running tests.
Some problems were found in the process and engine changes were made.
Now the fuel for the small ion, electric propulsion engine has been found, and it uses carbon dioxide polymers that have been rearranged by our molecules.
The fuel used in large ion propulsion engines is water.
These are all environmentally friendly fuels, which will never leak harmful gases and affect the organisms in the space shuttle. "
Zhou Yunsheng heard Niu Zhengfeng's explanation, he said in surprise: "I didn't expect that even carbon dioxide and water can be used as fuel. The world is really changing so fast that my brain can't keep up."
"Yunsheng, an ion propulsion motor, it uses ionization to form a recoil. This does not require fuss, any compound will become like this after strong ionization."
Li Hao saw that it was not far from their target laboratory. He asked Niu Zhengfeng the last question: "How fast is the ion-driven engine?"
When Niu Zhengfeng heard Li Hao's question, he immediately replied: "General Li, the speed of the ion-driven electric engine is not easy to measure. He always accelerated slowly at the beginning. Then he gradually accelerated and finally formed a higher speed.
With a small engine, it only takes more than two hours from Earth to the Moon. Use a large ion engine. His speed is wild.
Using a large ion engine, it can boost the space shuttle to its maximum speed. The time from Earth to Mars can be completed in just one month. "
Li Hao thumbed up and admired: "The performance of the ion-driven electric engine is really superb."
Ma Yiming stopped and said to them, "We're here. The space ahead is where the spaceflight and the shell are tested."
"Let's go in and see the performance of the shuttle shell." Li Hao said with excitement.
"General Manager Li, I don't know what danger will happen in the test place. This is a one-way transparent glass wall. There is also a blessing of a virtual light curtain here, which is most suitable for viewing."
They came into this empty test room.
At a glance, Li Hao saw the outer shell of the shuttle lying flat in the room.
The outer shell of this shuttle is one-piece. It is 25 meters long and wide. The wings are 9 meters long.
This is a bit ugly when combined with a conventional streamlined aircraft, he has a completely different body structure.
When Li Hao saw the appearance of the plane, he knew that the plane did not consider the aerodynamic shape at all. He relies on powerful stealth to drive the plane.
One aircraft manufacturing expert once said that. As long as there is enough thrust, even a brick can lift him into the sky.
Not to mention the space shuttle, most of which travel in a vast universe. The shape of the aircraft is not the main consideration, just practical.
It can be seen from the outer shell of the aircraft that the aircraft is equipped with two small ion engines. They are deployed on the wings on each side.
On the back of the space shuttle, a huge metal-shaped tube bulged. This should be left for large ion engines.
The size of the large ion engine can be seen from the outer shell of the shuttle, which accounts for almost one-fifth of the aircraft.
Ma Yiming watched the testing work of the scientific researchers on the opposite side through the protective glass.
He introduced: "General Manager Li, the basic shape of our space shuttle shell is like this.
It is made of super-strength steel through one-time forging of large machine tools.
The outer layer is coated with Yanjin coating. This is the Yanjin coating developed by Director Bi Ye and leading the scientific research team. It has many new uses.
In addition to the super strong steel skeleton inside the space shuttle. It is also often necessary to have a heat conduction system composed of inflammation gold.
A light curtain is displayed on the glass wall with an animation of the shuttle's cooling system.
On the other end of Yanjin is a molten salt solution. The heated molten salt flows into the large boiler room. Molten salt heats the water in the boiler, releases heat at the same time, and begins to circulate after cooling.
Through these thermal cycling methods, we can guarantee that we will encounter extremely high temperatures. The spaceship can also survive well in this state. "
"Start the experiment and see the results. This kind of thing is useless just to say." Li Hao looked ahead and said directly. ..
After Ma Yiming heard it, he immediately ordered the experiment to begin.
Upon receiving Ma Yiming's order, the researchers in the room have already started testing.
Through the virtual light curtain displayed on the glass wall, Li Hao can clearly see the strong burning resistance of the shuttle's shell.
They used high-power electromagnetic equipment to heat the surface of the shuttle's shell ~ EbookFREE.me ~ and saw the transmission through Yanjin. It transfers heat directly to the lava and then to the boiler.
The steam in the boiler is boiled, and the steam starts to drive the turbine to generate electricity. And store this electrical energy.
Li Hao saw that the temperature had reached an extreme temperature of 3500 ° C. The molten salt system was finally unbearable and began to collapse.
Heat builds up on a large scale, and the inflamed gold coating on the surface of the shuttle begins to break.
Ma Yiming said immediately: "The results of this experiment are perfect and prove that the heat removal system we designed is very effective.
The only disadvantage is that the molten salt is not well-matched and does not exhibit the characteristics of this material. "
"This is already very good. The big framework has been set up. After that, it is filled with stuff. These small problems can be solved through several test data." Li Hao said with satisfaction, feeling that this visit is worthy .
