I tinkered with cars and built a super military industry

After hearing Li Yifan's diagnosis, Yan Hua, who was originally a little excited, fell silent.

The three core components of the turbofan engine all have problems, what should we do...

Problems can be found, but they are not easy to prove.

This is not only true for scientific research, but also for other things.

This confirmation may come from the thing itself, or it may be caused by external forces.

But no matter which point, it must be confirmed.

Yan Hua thought for a moment and said:

"Academician Li Yifan, do you have a solution?"

Li Yifan nodded, "Yes!"

But Yan Hua frowned again.

It is not an easy task to get the three people in the aerospace power team to admit their mistake and start the process from scratch.

"Academician Li Yifan wants to redesign and manufacture the aerospace power unit, which may be very troublesome!"

"Unless you have to come up with ironclad proof."

"Otherwise, based on just a few words, it would be more difficult to get them to develop and manufacture than to move a planet." Yan Hua said.

"I'll do it. Just provide me with the materials." Li Yifan said.

"You come?"

Yan Hua's eyes showed a burst of disbelief.

Those are compressor blades, turbine blades and high-temperature resistant combustion chambers.

This will involve a lot of high-precision equipment and instruments.

Including materials science, high-precision casting technology, high-precision machining technology, high-precision multi-axis CNC machine tools, etc.

Even within the academy, the three veteran academicians of the aerospace power group have to divide their respective responsibilities.

No one in Haikou has boasted that he alone can develop and manufacture the three cores of the turbofan engine.

"Academician Li Yifan, do you know how to build a turbofan engine?" Yan Hua asked with confusion on his face.

Li Yifan nodded indifferently, ignoring Yan Hua who was full of questions.

Don't talk about building a turbofan engine.

The fighter jet modification system that Li Yifan has now unlocked can directly create a fighter jet.

But the engineers in the aerospace power group below immediately raised questions.

"This Academician Li Yifan is a little ignorant!"

"We, a group of veterans who have been working on aviation power systems for more than ten years, don't dare to say such big words!"

"I haven't packaged those three core components yet."

"It's normal. I worked for a full ten years before I touched the core components."

"There's no way those materials are really too valuable!"

"If you want to process these precious materials, you will be damaged if you are not careful."

……

Yan Hua finally chose to believe Li Yifan.

"Academician Li Yifan, can we start construction immediately?" Yan Hua asked.

"Okay, please prepare these materials."

After speaking, Li Yifan found a piece of paper.

Write down the required materials.

Yan Hua took the note, glanced at it, and couldn't help but twitch the corner of his mouth.

High-strength lightweight titanium alloy, powder ceramic metallurgy, special welding rods, etc.

There are not many materials required, just over ten kinds.

But the preciousness of each material is dozens of times higher than the price of gold.

Although Yan Hua doesn't particularly understand the three core components inside the turbofan engine.

But rare materials can still be understood.

Before Yan Hua could react, Li Yifan continued:

"In addition, prepare a high-precision lathe and a high-precision machine tool for me."

"High-precision modeling and casting machines are also needed."

Watching Li Yifan and Yan Hua go to the R&D and manufacturing workshop, the engineers of the aerospace power group did not follow them.

Because Li Yifan spoke, he needed an independent space.

Seeing Li Yifan's retreating figure, the engineers began to speak freely.

"These three core components cannot be achieved with high-precision auxiliary tools."

“Basically it still has to be made and polished by hand.”

“The only auxiliary equipment that can be used is high-strength titanium alloy cutting, micro-hole processing, etc.”

“The precision casting and special welding of hollow blades all require pure manual work.”

"It would give the maker a Stone Age feel."

……

Li Yifan followed Yan Hua to the independently developed manufacturing workshop.

The space here is not too big, only about thirty square meters in total.

Excluding the equipment, there is only about ten square meters of open space left.

And looking at the environment here, it is obvious that it was adjusted according to Li Yifan's requirements.

Li Yifan came to the workbench and sat down on the stool.

Yan Hua ran to prepare various rare materials in his hand.

Although it was a rare material, it was delivered to Li Yifan in less than half a day.

After Li Yifan had lunch, he started working on the system's 3D tutorials.

First, the hollow blade model of the compressor was built.

Then the turbine blade model and the combustion chamber model were created.

Normally, modeling is more difficult than manufacturing the finished product.

And some reusable materials will be used to produce several sets of finished products.

Then compare each set of finished products and finally determine the final set of finished products.

But for Li Yifan, who has a system, this doesn't have to be that troublesome at all.

Li Yifan didn't even finish a set of trial materials, so he just started correcting the mold.

Others calibrate the mold based on the finished product of trial materials.

Li Yifan came up directly to correct the mold itself.

If the engineers from the aerospace power group saw it, they would definitely say that Li Yifan was messing around.

Next, Li Yifan did the second step.

In order to be lazy, Li Yifan directly threw the required high-hardness light titanium alloy into the smelting furnace and let it melt.

It stands to reason that before this, it is necessary to use a high-precision lathe for cutting.

Put an appropriate amount of titanium alloy into the melting furnace for melting.

In order to save time, Li Yifan skipped it.

After smelting the high-hardness lightweight titanium alloy in the smelting furnace, Li Yifan randomly found a spoon.

The smelted high-hardness lightweight titanium alloy liquid was poured into the prepared grinding tools.

Such rough operation seems refreshing, but there is no sense of refinement at all.

After completing the blank of the compressor blade, Li Yifan wanted to save trouble.

A large piece of titanium alloy was directly thrown into the smelting furnace, and the turbine blades and combustion chamber blanks were fiddled with.

This wave of operations looks like a blacksmith going to the countryside to smelt aluminum pots for the country people.

Simple and crude, with no sense of refinement at all.
