I tinkered with cars and built a super military industry

Li Yifan used tongs to place the compressor blades, turbine blades, and combustion chamber blanks on the workbench.

The reason why I use fire tongs is because I can't use other tools.

In fact, there are many tools that look particularly sophisticated in this laboratory.

But the original intention of inventing these tools is to make things easier for researchers.

Furthermore, it is for some high-precision components to play a certain protective role during processing or moving.

But these fancy tools are a burden to Li Yifan.

Half an hour later, the three components taken out of the smelting furnace had mostly cooled down under the blowing of the fan.

Li Yifan picked up the blades of the compressor with his hands and looked at them.

The blades of this compressor are divided into high-pressure blades and low-pressure blades.

Normally, these two sets of blades are developed separately.

If you want to conduct research and development at the same time, it is a very challenging technology for scientific researchers.

The biggest test is the mentality of scientific researchers.

Because the curvature of high-pressure blades and the curvature of low-pressure blades are very different.

The arc of the low-pressure blade will be one section shorter, and its role is only to guide the initial intake air as quickly as possible.

The high-pressure blades are different, and the blade radian is obviously longer.

Its function is to supercharge the initial intake air.

And in the process of supercharging, it can be divided into three levels, also called multi-stage supercharging.

So that the final boost ratio can reach more than 25.

The compressor blades are circular in shape.

It is a hollow circular cylinder with many leaves.

And these leaves are all hollow.

Li Yifan put the compressor blade in his hand and looked at it [-] degrees.

Then I found a piece of sand somewhere and started polishing the blades.

Because the sand is too fine, it grinds too slowly.

Li Yifan looked around and found no coarser sand.

Finally being forced to do nothing, Li Yifan picked up the file and started polishing the blades.

In fact, for high-precision compressor blades like this, sand can be used.

But you can only use very fine sand, even the two thousand sand that Li Yifan just used was coarse.

Blades like compressors can only be polished with more than [-] sand. After all, the requirement is a micron-level difference.

However, Li Yifan has a system.

Even if he used a file to file the compressor blades, it would be harmless.

On the panel scanned by the system, there are not only naked-eye 3D teaching videos.

Moreover, the polishing progress of the compressor can still be detected from time to time.

So Li Yifan just grinds.

Just leave the rest of the data to the system.

With the file, Li Yifan can get twice the result with half the effort.

It only took two hours to polish the blades and the interior of the combustion chamber.

Next, Li Yifan put several sets of parts on the high-precision automated lathe.

All the surfaces that needed to be trimmed were polished.

After doing this, Li Yifan directly took the aviation power group and made the turbine engine casing.

I wanted to install the turbine blades, compressor, and combustion chamber I made on the casing.

However, during the assembly process, Li Yifan found that the shell was completely unsuitable for the blades he made.

The gap is extremely large.

Li Yi took out the compressor, turbine blades, and combustion chamber.

Start tinkering with the shell mold again.

The steps are the same, just tinker with the mold.

It's time to cut it on a high-precision machine tool.

Sand again.

Finally, use the automated high-precision lathe.

This process lasted another three hours.

Li Yifan placed the shell that had not yet completely cooled down on the workbench.

Then I couldn't wait to start assembling it.

From the inside to the outside, first carve out the cooling water ducts and air ducts of the combustion chamber.

The manufactured combustion chamber is coated, and then special welding is used to fix the combustion chamber to the shell.

Then install the compressor at the front end of the combustion chamber, leaving air intake ducts on the upper and lower sides.

And observe whether the air film can be used to cool the blades.

Finally, close the turbofan part to the casing and adjust the gap between the turbofan and the bearing.

After the main part of the front end is installed, the remaining mechanical part is the nozzle.

Because it is installed on a tank, the turbofan engine needs to be greatly modified.

The heat of the original flamethrow thrust must be recycled through the recovery device for secondary work.

In this way, not only can the power be improved.

It can also save fuel consumption.

Of course, the most important thing is to improve the stealth of the tank.

Because once a tank is on the battlefield, it can easily become a living target.

If this turbofan engine uses a tail nozzle design.

The heat it emits on the battlefield can easily be detected by enemy thermal imaging.

After completing the last step of the turbofan engine, it was already ten o'clock in the evening.

Li Yifan did not sleep in the research room this time, but came to the personal dormitory arranged for him by Yan Hua.

Perhaps because of a tiring day, Li Yifan simply washed up.

I fell on the bed and fell asleep. There was nothing wrong with sleeping in a strange bed and I was not used to it.

This sleep lasts until the next morning.

It wasn't until the alarm clock rang that Li Yifan was woken up.

Li Yifan rolled like a carp and rolled over to get up.

After washing up, Li Yifan navigated to the canteen, drank a bowl of rice porridge and gnawed two meat buns.

Then he went to the research and development room to perform finishing work on the turbofan engine.

The remaining finishing touches are some accessory assembly.

It is nothing more than oil passages, water passages, air passages, control harnesses and sensors, etc.

But Li Yifan decided to do it himself.

If others do it, he can rest assured.

This tinkering took more than half a day, and it was three or four o'clock in the afternoon when the assembly was completed.

Li Yifan asked Yan Hua to come over to help, and they used a special forklift.

Towed the turbofan engine out.

In the tank manufacturing workshop, Li Yifan hoisted the engine onto a tank.

This hoisting is very troublesome, as the engine compartment is originally small.

It was designed so that there is only enough space for two engines.

Because the normal assembly procedure is before the tank body is completely completed.

The two engines have already been installed first.

But now it is impossible to remove the turret and cut the body of the car in order to install an engine!

So no matter how difficult it is, we can only bite the bullet and stuff the turbofan engine into it.

There are four people in the suspended plug turbofan engine, one at the top, one at the bottom, one on the left and one on the right.

The four of them each took a good look at the gap they were aiming at, and then followed Li Yifan's command.

"Come on, push in."

"Boom!"

With a bang, the turbofan engine landed on the machine's foot pads smoothly.

Li Yifan took a long breath, feeling instantly relieved.

Just drop the turbofan engine into position and all that's left is to tighten the screws.

While Li Yifan was tightening the screws, Yan Hua sent a message to the aviation power team.

"The turbofan engine has been improved and assembled and will be tested this afternoon!"
