Chapter 1070 Atomic Rocket Engine

I think that everyone is a smart person, and they are all talents of the country. Now we just need to unite and work together to complete this 'manned spaceflight' program. "

After Zhao Zhongyao said this, everyone was looking at him. Each one is very serious. After all, everyone knows that only Zhao Zhongyao can lead them to complete the manned spaceflight program. It is impossible for others to do all this.

After Zhao Zhongyao said these words to everyone, he asked everyone to adjourn the meeting.

This day passed like this. For Zhao Zhongyao, he felt that this was a very important day. Starting today, he will devote himself to work again.

To complete this manned spaceflight program, the first thing to do is to develop a high-thrust launch vehicle. For Zhao Zhongyao, this feels like a very important task. He had to get this done.

Zhao Zhongyao first thought that before developing a high-thrust launch vehicle, the first thing to do is to solve the problem of the engine. Although jet engines are also used on rockets. But this engine is also different from the engine on an ordinary aircraft.

The rocket needs to send something weighing several tons into space, so the thrust of the engine must be very large. Because, the rocket itself plus the cargo to be carried generally weighs tens of tons or even hundreds of tons.

This requires that the rocket's engine must be of high thrust. Ordinary engines are simply unable to complete this important task.

Zhao Zhongyao had studied things like engines before. When he was studying the f-117 stealth fighter, he had studied a jet engine for a large cart.

Now it's time to study high-thrust rocket technology. Zhao Zhongyao just wanted to take the turbofan engine he had studied before and study it again.

But Zhao Zhongyao studied and studied, and felt that the thrust generated by the previous turbofan engine was still unable to send a rocket weighing dozens of tons into space.

This requires Zhao Zhongyao to research a new type of engine, which is specially used on rockets.

Zhao Zhongyao also knew a little about the rocket technology of his time before his death. You know, the rocket technology of his era generally used liquid fuel. That is, a mixture of liquid hydrogen and liquid oxygen is used as fuel to propel the rocket flight.

Although liquid fuel can produce a lot of thrust. But this fuel is consumed quickly. In order to complete the rocket's mission of sending goods or people into space, the rocket needs to carry a large amount of fuel.

This is the case with the high-thrust rockets in the United States. To send the space shuttle into space, the rocket needs to carry 2,000 tons of fuel. It can be said that the maximum weight of the entire rocket is the weight of the fuel tank.

Such a rocket is very bulky. Just like the rocket launched by the United States to launch the space shuttle, the rocket plus the space shuttle weighs more than 2,000 tons. Every time it is launched, a large amount of fuel will be consumed and a huge amount of money will be spent.

Zhao Zhongyao knew this too. After all, he was a Chinese-American scientist during his lifetime. Now he was reborn on another parallel earth, a parallel world like Huaguo.

Zhao Zhongyao knows that if he wants to solve the big cart rocket technology now, he must first think about what types of rocket engines there were in the world before his death. He knew that in the world in which he lived, several types of rocket engines had been produced. Generally speaking, it is mainly divided into solid state and liquid state engines.

These two engines have different characteristics, and it can be said that each has its own advantages. Zhao Zhongyao wants to study a high-thrust engine now, so he can only learn from those engines he knew before his death.

Zhao Zhongyao knew that there were many kinds of engines in the world before his death. Among them, there is a very advanced engine called plasma engine.

This engine is different from ordinary engines in that it is not propelled by fuel, but by electricity. It is an engine that uses electricity to heat the air, create plasma, and then propel the rocket into flight.

Plasma engine is a kind of electric propulsion system, and its application is quite mature at home and abroad. The main medium of its application is plasma. It uses the Lorentz force to accelerate charged atoms or ions through a magnetic field to propel a spacecraft in reverse, the same principle used in particle accelerators and rail guns.

In science fiction, flying machines have always been able to power the entire journey of interstellar travel. But in reality, rocket propulsion engine technology simply cannot achieve this. The engine of a chemical rocket looks small compared to its exposed propellant tanks, but it has a big appetite. "Eat a lot, but work efficiency is not high."

The massive energy gobbled up by this engine is only effective in providing short-term power—the stored fuel is quickly used up, and the propeller is immediately thrown away as garbage. Most of the chemical rocket's fuel is used to escape the earth's gravity, and the remaining bit is used to propel the rocket's "space glide". Rockets fly to their destinations only by inertia. For interstellar flight, this kind of engine is obviously not enough.

"Saturn 5" is a typical representative. Its first stage holds 2,075 tons of liquid oxygen kerosene propellant. Once the engine fires, it can "drink" all of these "drinks" in 2 minutes and 34 seconds. The high-temperature gas is ejected at a speed of 2900 m/s, but it is only enough to send a payload of 47 tons to the moon. Of the 3,500 tons of thrust that can be generated, a large part is used to "drag" the rocket itself and more than 2,000 tons of fuel.

So its "specific impulse" is not high, only more than 300 seconds, which shows that its propulsion efficiency is low. This is why it is necessary to use a huge rocket to send a person with a small mass into space. Plasma engines, or "ion thrusters" as they're commonly called, take a completely different approach to chemical rockets. It uses the Lorentz force to accelerate charged atoms or ions through a magnetic field to propel a spacecraft in reverse, the same principle used in particle accelerators and rail guns.

"Plasma rockets provide relatively little thrust for a certain period of time, and then once in space, they gradually accelerate to fly like a sailboat with a tailwind, until they are faster than chemical rockets." Missions using plasma engines, such as NASA's asteroid-hunting Dawn mission.

One of the purposes of the European Space Agency's smart-1 probe that hit the moon is to verify how to use ion propulsion technology to send future probes into orbiting Mercury. track.

Although the plasma engine has many advantages, it also has some disadvantages. That is to say, it must continuously provide electricity to maintain its work. It is a machine that 'drinks' electricity.

After Zhao Zhongyao thought about the many kinds of engines he knew before his death, he thought that now he would learn from each other's strengths and develop a very advanced rocket engine. Only in this way can the manned spaceflight program this time be completed.

After Zhao Zhongyao thought about it, he felt that the atomic engine he had studied before could be used. After all, if this kind of engine is used on a rocket, it can reduce the weight of the rocket and does not need to carry a lot of fuel.

Moreover, nuclear power is used to provide energy, and only a small amount of nuclear fuel can be carried to maintain the rocket's long-term flight needs.

Thinking of this, Zhao Zhongyao hurriedly started designing his new rocket engine. After a month of hard work, he finally designed his new atomic rocket engine.

When Zhao Zhongyao designed this atomic rocket engine, he was very happy. He quickly found Cheng Yu. After all, Cheng Yu is Zhao Zhongyao's best assistant. He is also an expert in aerodynamics.

After Zhao Zhongyao designed the atomic aero engine, he called Cheng Yu to his office. He looked at Cheng Yu, put his design drawing in front of him and said, "Old Cheng, take a look, how about this drawing I designed."

As soon as Cheng Yu heard what Zhao Zhongyao said, he quickly got the drawings and looked at them. When he saw that the drawing said atomic rocket engine, he was very surprised. He didn't know what kind of engine Zhao Zhongyao designed.

"Mr. Zhao, what kind of engine is the engine you designed? Why haven't I heard of it, what kind of atomic rocket engine." Cheng Yu looked at Zhao Zhongyao very puzzled and asked.

After hearing what Cheng Yu said, Zhao Zhongyao looked at him again and said: "The engine I designed uses the working principle of the atomic engine I designed before. Then, I improved it and made it an aviation engine. Rocket engine."

As soon as Zhao Zhongyao said this, Cheng Yu was very curious. He looked at Zhao Zhongyao again and said, "What are the advantages of your engine, and what is its working principle?"

After listening to Cheng Yu's words, Zhao Zhongyao smiled and said, "The working principle of the engine I designed is similar to that of the atomic engine I designed before. The only difference is that the engine designed this time The atomic engine is to let the engine generate high-temperature gas, and then propel the rocket to fly. Although the previous atomic engine also produced high-temperature gas, the previous high-temperature gas only drove the internal combustion engine to rotate. Compared with the current atomic engine, it is only different in terms of thrust. the difference.

Of course, the thrust of the rocket engine developed this time must be dozens of times the thrust of the atomic engine for tanks developed before. It can be said that the rocket engine I am developing now is an upgraded version of the original atomic engine. "

As soon as Zhao Zhongyao said this, Cheng Yu admired Zhao Zhongyao very much. He looked at Zhao Zhongyao and said: "Mr. Zhao, you are really amazing. If it weren't for you, we would not be able to complete this important task. Now, you have designed the core components of the high-thrust rocket Come out, then the next step is to start production."

"Of course, we are also short on time and heavy on tasks now. We must develop the rocket engine as soon as possible. Only by developing this core component first can we further develop high-thrust rockets." Zhao Zhongyao looked at Cheng Yu again and said.

"Okay, I'll listen to Mr. Zhao, then you have developed this high-thrust rocket engine now, so let's develop it together in the next step!" Cheng Yu looked at Zhao Zhongyao again and said.

"Okay, then the next task will be handed over to you. I will continue to design other systems of the rocket. This core component has been designed now. But to design a rocket, there are many components. I also need Continue to design other components.

Now I leave this production task to you. You must strictly follow the content drawn on the drawing. Produce this high-thrust atomic rocket engine. Only by producing it first can we continue to study high-thrust launch vehicles. "

Zhao Zhongyao knew that his time was very tight. To accomplish such a major task, there are many things to do. Designing a high-efficiency atomic rocket engine is not enough.

"Okay, Mr. Zhao, then you can entrust this difficult task to me! I will definitely launch this advanced atomic rocket as soon as possible."

produced by the machine. When the time comes, you will be satisfied. "

Cheng Yu knew that he could not design such an advanced rocket engine. But I can help Zhao Zhongyao produce this advanced atomic rocket engine.

"Okay, then let's split up! I will continue to design other parts of the rocket, and you can produce this advanced atomic rocket engine!" Zhao Zhongyao looked at Cheng Yu again and said.

"I will, I will definitely complete this task soon." Cheng Yu also looked at Zhao Zhongyao with certainty and said.

After finishing speaking, Cheng Yu walked out of Zhao Zhongyao's office. He took the blueprint and came to the laboratory.

"Come on, let me show you something." When Cheng Yu came to the laboratory, he took out the drawings of the atomic engine designed by Zhao Zhongyao, and asked everyone to take a closer look.

All the researchers came to Cheng Yu's side as soon as they heard Cheng Yu's words. When everyone saw the atomic rocket engine designed by Zhao Zhongyao, they all had surprised expressions. After all, everyone doesn't know what the rocket engine will look like. Now looking at the rocket engine designed by Zhao Zhongyao, I feel very surprised. None of them thought that Zhao Zhongyao would design an atomic rocket engine.

"This is the atomic rocket engine, doesn't it look very ordinary!" A thin young man said looking at the blueprint in Cheng Yu's hand.

"That's right, our Mr. Zhao is really talented! Except for him, it is impossible for others to design such an advanced atomic rocket engine."
