Ma Yiming immediately came to the spirit, this is Li Hao's recent results to investigate himself.

Today is really his lucky day, and this day is really the most appropriate.

Now there has been a major breakthrough in the space program. Just lead Li Hao and them to see the effect and show their abilities through specific examples, which is one of the best ways to show their abilities.

Ma Yiming immediately said respectfully: "Mr. Li came by coincidence, we are constantly verifying whether the effect of the space shuttle's shell can achieve our goal recently."

Now it has been largely successful, and preparations are underway to test the shuttle shell to the limit. Let's take a look at this experiment together. ”

Li Hao immediately nodded in agreement: "Your movements are so fast, I didn't expect that even the space shuttle shell was made."

I knew that the space shuttle's hull required a very high standard of technology, and that it was not just about keeping it intact in the atmosphere.

It is also necessary to prevent the irradiation of small meteorites and high-intensity cosmic radiation in the universe. After all, the space shuttle we are studying is not playing in circles around the Earth's outer orbit.

He's going to go deep into the solar system for a long voyage. ”

Li Hao said that the space shuttle was sailing in the solar system, and he remembered whether the space shuttle could meet the requirements of long-distance travel, and the most critical piece of equipment.

You must know that many equipment in Huaxia can be produced by itself, but the engine is generally not good.

As they walked to the laboratory, Li Hao asked Niu Zhengfeng: "Niu Gong, how is the engine of the space shuttle progressing now?" ”

Niu Zhengfeng said confidently: "For the engine project, Mr. Li doesn't need to worry. We will definitely complete the project on time.

Now the engine has been basically designed, and it is undergoing long-endurance operation tests.

In the process, some problems were identified and changes were made to the engine.

Now the search for fuel for the small ionic, electric propulsion engine is made of carbon dioxide polymer that has been rearranged by our molecular realignment.

The fuel used in large ion-electric propulsion engines is water.

These are environmentally friendly fuels that will never leak harmful gases and affect the creatures inside the shuttle. ”

When 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 changing so fast that my brain can't keep up. ”

"Yunsheng, ion propulsion motor, it is ionized to form a recoil force. There is no need to make a fuss about this, any compound that has undergone strong ionization will become like this. ”

Li Hao saw that it was not far from the laboratory of their target, and he asked Niu Zhengfeng one last question: "How about the speed of the ion electric propulsion engine." ”

When Niu Zhengfeng heard Li Hao's question, he immediately replied: "Mr. Li, the speed of the ion electric propulsion engine is not easy to measure. He started with a very slow acceleration. After that, it gradually accelerates until it becomes a higher velocity.

With a small engine, it takes just over two hours to get from the Earth to the Moon. Large ion engines are used. His speed is furious.

Using a large ion engine, it was able to raise the shuttle to its ultimate speed. It only takes one month to get from Earth to Mars. ”

Li Hao gave a thumbs up and exclaimed: "The performance of the ion electric propulsion engine is really superb. ”

Ma Yiming stopped and said to them: "We have arrived, and the place ahead is the place where the space flight and the shell are tested." ”

"Let's go in and see how the shuttle shell performs." Li Hao said with some excitement.

"Mr. Li, I don't know what danger will happen in the test place. This is a one-way transparent glass wall. There is also the blessing of a virtual light curtain here, which is the best for viewing. ”

They made their way to the empty testing room.

Li Hao saw the space shuttle shell lying flat in the room at a glance.

This shuttle shell is made in one piece. It is 25 meters long and 6 meters wide. The two wings are each 9 meters long.

This is a somewhat ugly and completely different structure from a conventional streamlined aircraft.

When Li Hao saw the appearance of this plane, he knew that this plane did not consider the aerodynamic shape at all. He relied on powerful stealth to propel the plane.

There is an expert in the manufacture of airplanes who once said. As long as there is enough thrust, even a brick can lift it into the sky.

Not to mention the space shuttle, most of which travels in the vast universe. The shape of the aircraft is not the main consideration, practicality is good.

It can be seen from the shell of the aircraft, which is equipped with two small ion engines. They were deployed on the wings on both sides, respectively.

The back of the space shuttle, bulging with a massive metal-shaped pipe. This should be left for large ion engines.

The size of a large ion engine can be seen from the shuttle shell, which is almost a fifth the size of the aircraft.

Ma Yiming: They observed the test work of the scientific researchers opposite through the protective glass.

He introduced: "Mr. Li, the basic shape of our space shuttle shell is like this.

It is made of super-strong steel and is forged in one pass by a large machine tool.

The outer layer is coated with a Yanjin coating, which is a Yanjin coating developed by the scientific research team led by Director Bi Ye, and it has many new uses.

The interior of the space shuttle is in addition to a super-strong steel skeleton. It is also common to have a thermal conductivity system composed of hot gold.

A light curtain appears on the glass wall, on which an animation of the space shuttle's cooling system is playing.

At the other end of the flame gold is a molten salt solution. The molten salt, which is heated very highly, flows into the large boiler room. Molten salt heats the water in the boiler, releases the heat, cools it and starts circulation.

With these thermal cycles, we can be sure that we are encountering extremely high temperatures. Spaceships can also survive well in this state. ”

"Start the experiment and see the results, this kind of thing is useless just by talking about it." Li Hao looked ahead and said directly.

When Ma Yiming heard this, he immediately ordered the experiment to begin.

After receiving Ma Yiming's order, the scientific researchers in the room had already started the test.

Through the virtual light curtain displayed on the glass wall, Li Hao can clearly see the strong burn-resistance of the space shuttle's shell.

They used high-power electromagnetic equipment to heat the surface of the space shuttle's shell.

Just see it passed through the flame gold. It transfers heat directly to the lava and then to the boiler.

The steam in the boiler is boiled, and the steam begins to drive the turbine to generate electricity. And store that electricity.

Li Hao saw that the temperature had risen to the extreme temperature of 3500 °C. The molten salt system finally couldn't take it anymore and began to crumble.

The heat accumulated on a large scale, and the gold coating applied to the surface of the shuttle began to deteriorate.

Ma Yiming immediately said: "The results of this experiment are perfect, which proves that the heat rejection system we designed is very effective.

It's just that the only drawback is that the molten salt is not well proportioned, and the characteristics of this material are not brought into play. ”

"It's already very good, the big frame is in place. After that, it's all about filling things inside. These small problems can be solved with a few trial data. Li Hao said with great satisfaction, feeling that this time it was worth the trip.
