Black technology: I have a refitting factory

Chapter 22 Engine modification completed

"This alloy is more powerful than imagined!"

Su Qi sighed secretly.

When he was looking at the plan, he was already amazed by the performance of this alloy.

It turns out that the weight is still light, which is so good that it is inhumane!
Produced by the system, it is truly extraordinary.

After the joy, Su Qi immediately entered the state again.

The engine needs 72 blades, and he just spent an hour making one.It takes 72 hours to finish all without sleep.

There are still compressors and shapes to be changed in the back.

He suddenly felt that one week was not enough.

……

Smelting, plasticizing, drilling, and ceramic coating.

Su Qi repeated the same steps for five consecutive days.

As the saying goes, practice makes perfect, and the follow-up time does not take that long.

On the fifth day, he had finished manufacturing all the blades, 72 of which were neatly stacked on the side of the workbench.

After the blades are completed, the most important thing left is the compressor.

The compressor is also a very important part of the aircraft engine. Its main function is to compress the air and increase the temperature, thereby increasing the combustion efficiency of the combustion chamber to increase the thrust of the engine.

Su Qi didn't know much about this before.

After checking the information, I found that the plan given by the system was a bit scary.

Generally speaking, the performance of the compressor mainly depends on the boost ratio.

The boost ratio is generally related to the tip tangential velocity.

The tangential speed of the active aircraft engine is about 400-500m/s, the boost ratio of the single-stage compressor is 2.8, that of the two-stage compressor is 4.0, and that of the three-stage compressor is about 6.5.

The plan given by the system is a four-stage compressor, and the blade tip tangential speed of the compressor exceeds 700m/s, which means that according to the conversion, the boost ratio is about 9.1!

Hang all the compressors now!
What's even more frightening is that it's far from that.

According to the calculation in the system plan, the compressor blade has a lower spin-to-span ratio and a higher consistency.In other words, the boost ratio will be further increased.

"I just don't have a complete plan. Just write like this, and I can probably publish a few papers. Maybe it will be the top journal paper. It's a pity..."

After studying the plan, Su Qi sighed lightly.

Papers are definitely not published.

This thing is too important, once it is published, the whole world will know it.

He doesn't want to.

These things are still in the hands of Hua Guo.

Science knows no borders, this sentence has long been falsified.Some outdated technologies can be published, and the most advanced technologies should be kept in our own hands.

"Go, go!"

Su Qi rested for a while, and operated the high-precision mechanical arm to continue working.

When you are tired, put it down and make up some knowledge about engines.In case others really come to ask in the future, if they don’t understand anything, then it’s unreasonable.

The basic theory of knowledge still needs to be mastered a little bit.

Compressor modification is much easier than blade modification.

It took a day for Su Qi to complete the modification.

"Assemble it and see the performance!!"

Su Qi was quite looking forward to it.

The compressor and blades have been refitted, and the whole refit is almost done.

Installation was not an easy task.

It is necessary to remove all the original blades properly, and then install the modified blades.It's a delicate job that can easily be ruined if it goes wrong.

In addition, the disassembly of the compressor is also a troublesome thing.

But for Su Qi, these are minor problems.

With the high-precision arm, all the installation has been completed in less than an hour.

Soon a streaking engine appeared in front of me.

In addition to the beauty of craftsmanship in the blades and compressors, the rest can still be described as tattered.

"Taking it out like this should also have a unique aesthetic feeling..."

Su Qi had a weird expression on his face.

He took a bucket of oil from the storage room and slowly poured it into the engine oil tank. After it was almost poured, he found a shelf to fix the engine and put the measuring sensor on it.

After thinking about it, Su Qi found a few more steel cables and fixed them.

Although it is a small and micro aero engine, the thrust theory will not be too large, but the system has been modified, and everything is possible.It's still more appropriate to be safe.

Everything was ready, and after double-checking that there was no problem, Su Qi pressed the start button, and an electrical signal was transmitted from the button to the engine.

hum!
hum!
The engine blades turned slowly, then faster and faster.

boom!
A heat wave emerged from the tail of the engine, spraying countless dust on the ground.The originally fixed bracket began to shake.

Watching the numbers on the sensor begin to change, Su Qi silently calculated in his mind.

"2kN!"

"5kN!"

"8kN!"

"10kN!"

"15kN!"

……

At this time, the frame that originally fixed the engine began to tremble.

"If I hadn't temporarily added the steel cable, it would be the end of the calf..."

A trace of fear flashed in Su Qi's heart, followed by excitement.

He has already overestimated as much as possible, but the value in front of him still makes him click his tongue!

You must know that the current best engine thrust-to-weight ratio is only about 12.According to his calculations, the thrust-to-weight ratio of the engine in front of him has reached 15!

That's not the point.

Most importantly, this is still an engine that has only been modified by two-fifths.

The combustion chamber driving the power and the air intake have not been modified yet.

After this modification, the thrust-to-weight ratio...

Su Qi's scalp went numb just thinking about it.

The system produces genuine cowhide.

After recording the parameters, Su Qi hurriedly stopped the engine.

Without him.

He felt like he couldn't hold the tightrope any longer!

at this time.

Li Haolei sent a message

【Uncle, what's the matter? 】

When Su Qi saw the news, he was stunned for a moment, and then his mouth twitched.

He suddenly realized that there was going to be a competition the day after tomorrow, so he only asked now.

This guy……

Shaking his head, Su Qi casually took a photo and sent it over.

[Only changed part, the performance is almost enough, but the appearance is poor, it should be fixed tomorrow afternoon. 】

[Ragged wild beauty, his uncle is still as good at craftsmanship as ever.Then leave it to his uncle. I'll pick it up tomorrow afternoon. 】

【Row! 】

Seeing that Li Haolei didn't send any more messages, Su Qi sighed helplessly.

This stuff...

What is the modified data, do not ask.

It's really the same as doing homework in college.

the other side.

Li Haolei was playing Yi Dao 999 with peace of mind.

He saw the picture, but only modified it a little, not like Su Qi's style.But he thinks that seven days is too much time...

Su Qi has always been reliable in his work, as long as there is no problem, he can achieve his goal.

And he didn't expect to win the first place, as long as he could win an award, and then get Professor Lin to take pictures.

No matter how you look at it, it's not a big problem!

What to ask, there is nothing to ask!

"Uncle takes action, no need to ask!" This is the slogan of their dormitory.
