Siheyuan: The Era of Struggle

Chapter 198 The drawings designed by Yang Ning cannot be used? (Subscription required)
"It's still a material problem!" Yang Ning sighed and said helplessly.

"Alright, I think you two are too greedy. The most important thing for us now is to solve the problem of creating something from scratch. As for better missiles, let's consider it after the material problem is solved!"

Mr. Guo looked at the two people with heavy expressions, smiled and said.

"If our steel production hadn't increased, I would have used pig iron to cast the shock tube for the wind tunnel model over there!"

"Hehe~" After hearing what Mr. Guo said, Yang Ning and Mr. Qian also laughed embarrassedly.

We don't even have our own missiles yet, but we're already thinking about continuing to improve on our original goals. That's really a bit too ambitious.

"By the way, Yang Ning, did you bring the engine drawings you designed? If you did, Mr. Guo, the dynamics expert, is here too. Let's take a look at them together."

"If there is no problem, I will start designing our missile based on your engine."

Mr. Qian concealed his embarrassment and changed the subject instantly.

"Oh?" After hearing what Mr. Qian said, Mr. Guo looked at Yang Ning in surprise: "You designed a missile engine by yourself?"

“Hehe.” Yang Ning smiled embarrassedly: “I just read a lot of books, so I can calculate quickly. As long as I have an idea, I can immediately calculate whether it is feasible. It’s purely a trick.”

Listen, this is just a trick. This Versailles makes Mr. Guo want to hit someone.

"Such talent is really enviable!" However, Mr. Guo finally resisted the urge to take action and said to Yang Ning with envy.

To be honest, a computer with a computing speed of 10 billion times per second cannot compare to Yang Ning's role in scientific research.

After all, no matter how fast a computer is, it does not have the logical thinking and imagination of humans. Even if it did, the corresponding technical software could not compare with humans.

"Yes, fortunately Yang Ning belongs to us, otherwise if this kind of talent fell into the hands of Eagle Sauce or Big Brother, it would make people feel desperate just thinking about it!"

Mr. Qian also deeply agrees with this. If the United States or Big Brother really had someone as talented as Yang Ning, coupled with the industrial level and scientific research capabilities of these two countries, it is hard to imagine how big the gap will be between us.

Seeing that the two were talking more and more outrageous, Yang Ning hurriedly took out the missile engine blueprint he designed and said, "Okay, guys, let's see if this design can be used?"

After hearing Yang Ning's words, Mr. Guo put away his envious look, took the drawing and started to look at it.

"Wow, this blueprint is really accurate. Can you draw such a complex structure diagram by yourself?"

When Mr. Guo saw the design drawn by Yang Ning, he exclaimed in admiration.

"Hehe, practice makes perfect!" Yang Ning said modestly.

That’s right. After all, Yang Ning has to deal with so much research data every day, and sometimes he needs to draw corresponding drawings based on the calculated data. In addition, after turning on the super brain mode, his control over his body has been greatly improved. How can the drawings he draws not be standard?

Because Yang Ning had already given the final data in advance for the places that needed calculation on the design drawing, there was no calculation problem.

Mr. Guo and Mr. Qian only need to use these data to see whether this design can meet the requirements of the new missile.

After all, the overall structure of the missile must still follow the principles of aerodynamics, and the engine is only a part of the missile.

"Hiss~" Mr. Qian couldn't help but take a breath when he saw the various data listed on the drawings.

"The longest working time of your engine is eight seconds?" Mr. Qian looked at it for a while, then looked up at Yang Ning and asked.

"That's not right. Take the R5 missile that Big Brother is equipped with this year as an example. Its engine uses methanol as fuel. According to the maximum thrust requirements and the combustion rate of methanol, the fuel in your engine can't last that long, right?"

Mr. Guo also looked at Yang Ning in confusion and asked.

The reason why he took the Big Brother's R5 as an example is because the range of this ballistic missile is similar to the range of the missile we are going to design, and the requirements for engine thrust are also similar.

"The engine I designed does not use methanol as fuel."

Seeing the confusion of Mr. Qian and Mr. Guo, Yang Ning explained.

"I designed this engine to use liquid hydrogen as fuel. The reason why Big Brother uses methanol as fuel for missiles is because their current high-temperature resistant materials do not meet the standards, so they choose methanol that can cool the engine."

"But the thrust generated by methanol combustion is definitely not as strong as that of liquid hydrogen. And we have just conquered the problem of high-temperature resistant materials. The high-temperature resistant materials we have developed can definitely withstand the high temperature generated by liquid hydrogen combustion for a short period of time."

“So the operating time of this engine is not calculated based on the combustion rate of methanol, but liquid hydrogen.”

"What is the maximum thrust of this engine?" Mr. Qian asked after listening to Yang Ning's explanation and taking a look at the design drawing.

"The maximum thrust can reach 524 kilonewtons. Combined with the engine's operating time, if this engine is used on the big brother R5, it can definitely increase the missile's range by %."

"Then the range is about 1,500 kilometers?" Mr. Guo couldn't help but ask in surprise.

"Almost!" Yang Ning nodded.

"With the same takeoff weight as the R5, the range can be increased by %. If there is a better aerodynamic design, wouldn't it be able to go even further?"

Mr. Guo looked at Mr. Qian excitedly, feeling an urge to try it out.

Mr. Qian looked at the design drawing in his hand, thought for a while and said, "Our missile body material is not as good as that of Big Brother, which means that our missile body needs to be heavier. Even if the aerodynamic layout is optimized, the range can only be about the same as that of the R5 after using this engine! Unless the missile body material is made of more expensive titanium alloy."

"A range of more than 1,400 kilometers can meet our current needs."

Although Yang Ning was a little disappointed after hearing what Mr. Qian said, what Mr. Qian said was true.

The body material of the big brother R5 is the same material as the skin of the World War II MiG-21 fighter. We currently do not have a material with the same performance to replace it, so we can only increase the thickness of the body.

"Not only that, the diameter of this engine is a bit too large. The larger the diameter of the missile, the more difficult it is to control its flight attitude, and the greater the air resistance."

Mr. Qian put down the design drawing, took out a pen and paper and started calculating.

After hearing this, Mr. Guo also started thinking about the drawings.

For a moment, the study fell into silence, with only the rustling sound of paper and pen rubbing against each other.

Seeing this situation, Yang Ning did not dare to disturb the two and could only sit aside nervously and wait quietly for the final result.
