Black technology: I have a refitting factory.

Chapter 112 Professor Lin’s New Year’s Gift

"The first stage has actually been completed, Professor Lin and the others are much faster than expected!"

After hanging up the phone, Su Qi muttered to himself.

In the past week, he didn't go to the attack team much.I remember that when I went there a week ago, Professor Lin told him that the first phase of verification might not be completed until next year.

Unexpectedly, it was completed now.

"I have to change my ticket..."

Su Qi had a slight headache. He had already made an agreement with the old man and old lady to go home tomorrow.

Now it can only be delayed a little longer.

The first stage of verification is still very important.

He is very confident in the blueprints given by the system, but other people in the tackling team don't know. This is a big deal for everyone and determines the future development of the new engine.

As general counsel, it would be inappropriate not to go.

And he also wanted to see what the new engine designed according to the drawings would look like.

Think about it, and look forward to it!

night.

Many people in the tackling team suffered from insomnia.

Su Qi didn't fall asleep too much.

This new type of engine doesn't look like he modified it with the magic modification system. It's really cool, but it costs modification points and people, so it's not a mass production plan.

And once this thing is successfully verified, it can be mass-produced in the future.

In other words, from the time he obtained the system to the present, he was the first step in truly pushing China towards the sea of ​​stars.

……

The next day.

Early in the morning.

The park where the attack team is located.

A large underground laboratory, inside this laboratory is China's most advanced aviation testing equipment.

"Su Qi should be here soon, let's start when he arrives!"

Lin Chengdong looked through the glass at the engine on the test bench with some excitement.

At this time, a group of engineers are carefully putting the engine on, and at the same time connecting the instruments required for measurement.

"Old Lin, Old Sun, do you think we can succeed this time?"

Mr. Huo looked at the test stand, with complex expressions in his eyes, including anticipation, excitement, and worry, all kinds of emotions intertwined together.They came up with this thing based on Su Qi's information.

In theory, it has been deduced repeatedly, and the problem is not big.

But theory is theory after all, and everything can only be proved through practice.

"It should be possible... The thing given by that boy Su Qi, he always said that he had speculated on it. But in fact, there is no big problem in verification."

Mr. Sun took the words, paused, and then said, "But I really didn't think about it before, that it can be designed like this. This kid's idea is very interesting.

Originally, I just wanted to get a high-explosive engine out, but I didn't expect to give a design plan for a variable-cycle engine. "

"When this variable cycle engine comes out, it will break the pattern of fighter jet engines. I don't know how many years it will take for Lao Mei to catch up, hahaha!"

Lin Chengdong laughed, and then looked at the test bench in a daze.

A variable cycle engine refers to an engine that can adaptively change the bypass ratio of the engine according to the speed.The so-called bypass ratio refers to the ratio of the air flow in the outer bypass duct and the inner bypass duct when the airflow enters the engine.

The larger the bypass ratio, the smaller the volume ratio of the combustion chamber, the lower the fuel consumption of the aircraft, and the better the airworthiness and economy.

Engines with small bypass ratios have good high-speed performance and are conducive to increasing the maximum speed.Therefore, all fighter jets in the world now use engines with a small bypass ratio, which is a fixed value. That is, the air cavity volume of the internal and external bypasses cannot be adjusted and cannot automatically match the speed of the fighter jet.

This will reduce the fighter's endurance.

Su Qi’s proposal is to adjust the shape, size, and position of some structures to change the air flow distribution of the internal and external ducts, taking into account the requirements of economy, acceleration, and high thrust within the flight envelope.

Specifically, it maintains a high bypass ratio under subsonic cruising conditions and uses a turbofan operating mode; maintains a low bypass ratio under supersonic or hypersonic speeds and adopts a turbojet operating mode to achieve automatic adaptation of engine performance.

It's a very wild idea, but the key is that it has concrete implementation.

Su Qi is truly a genius among geniuses when it comes to aircraft engine design.

"Uh, can't I be late?"

Su Qi's voice awakened everyone from their thoughts and fantasies.

Feeling everyone's eyes focused on him, Su Qi looked at his phone uncomfortably. It was only nine o'clock and he was not late. He was half an hour ahead of the agreed time.

"Hahaha, don't doubt yourself, you are not late. We arrived early. Thinking that this thing needs to be verified, a group of us can't sleep, so we just get up early."

Lin Chengdong explained haha.

After a pause, he continued, "But speaking of it, I'm still waiting for you, otherwise we would have started long ago."

Su Qi: "..."

"Now that you're here, let's get ready to start."

Lin Chengdong restrained his smile, picked up the microphone with some seriousness and shouted, "Follow the rehearsal instructions and start to execute."

His voice resounded throughout the testing room, and after hearing it, the engineers below began to test the instruments in an orderly manner according to the established procedures.

"Wait a while, and check the instruments, the engine, and inject fuel again. These processes may take about half an hour."

Lin Chengdong explained to Su Qi, "It's not complicated, but the result of this data is very important. It must be checked and checked to ensure that the result is correct."

"Ok!"

Su Qi nodded, expressing his understanding.

"By the way, I have one more thing to tell you. The certificates for honorary professors and expert consultants that I told you before have been obtained.

This thing does not need to be kept secret, take it back and show it to your family. "

Lin Chengdong seemed to have remembered something and said again, "This can be considered a New Year's gift from us to you. It's very convenient for you to go anywhere with this thing."

No matter what you do, we support you. "

"Thank you!"

Su Qi smiled.

He had almost forgotten about it.

If this thing can be shown to the family, it is indeed a good New Year gift.He was a little looking forward to how the old man and old lady at home would react when they saw these things.

A little looking forward to it.

This New Year should be a happy one.

Half an hour is not a long time, but at this time, it seems very long.

When everyone was waiting in a hurry.

"Report to Chief Engineer Lin that all tests have been completed and the fuel has been injected. Please give instructions on the next step!"

When this voice reached the monitoring room, everyone's spirits were shaken.

The critical time has come!
"According to the scheduled plan, start to ignite!"

Lin Chengdong said this sentence calmly facing the topic.
