Chapter 17 Design Drawings of Turbofan Engine
"Understood, understood, we will fully investigate the authenticity of this situation."

"I will notify you when the results are available."

Contact the police operator and promise him to fully investigate the true outcome of this situation.

"Thank you."

"What is your name?"

"Li Youchen, a student from Polytechnic University."

"Okay! Please keep in touch."

As soon as he finished speaking, the 110 alarm call hung up.

Li Youchen put down the function phone and thought, will this lead to revenge?

After all, it has been seen that this scam is likely to be targeted.

No matter what, we have to face it anyway, so why not wait for the results of the investigation by the Maintenance Police Department to come out.

Baihong Manor.

After walking into the room and sitting down at the desk, Li Youchen continued to write, designing the technical drawings of the turbofan engine as the original manuscript for the model machine.

The structure of a turbofan engine consists of an inlet, a compressor, a combustion chamber, a turbine, a tail nozzle and other parts. The main fuel is kerosene.

Turbofan engine. Compared with the real turbofan engine inside a fighter jet, Li Youchen designed a small, simplified version of the turbofan engine.

The difference between the large turbofan engine and the large turbofan engine is that the internal parts are larger than the small turbofan engine, especially the width of the inlet, compressor, turbine and other parts. Different sizes of parts can be used to assemble large and small turbofan engines, and Improved engine.

Wind tunnel experiments, designing turbofan engines, Li Youchen couldn't help but think of designing large turbofan engines, and wind tunnel simulation experiments are the most important.

Now, when making a small turbofan engine, you also need to prepare a high platform.

After the titanium alloy steel is delivered, it will be made immediately, and the high platform must also be prepared.

Because it is small and not large enough, experiments like wind tunnels are not necessary.

That's what large turbofan engines only need.

Afternoon, smelter.

The hot red molten iron emits scorching gas in the pool.

As the workers opened the gate, the red molten iron flowed down the ramp to the cooling equipment like water, changing from liquid to semi-solidified solid. After passing through the compression equipment, it formed a steel coil that was stretched very long, and passed through the workers' iron hooks. Pull, place it on a holder, and begin to wrap the elongated steel coil into a roll shape.

Next to them, while other workers were busy, the person in charge of the smelting plant, Director Liu, and some talents who knew some periodic table synthesis techniques looked at the drawings, and they all looked sad.

"No! This is the first time I've seen this kind of titanium alloy steel forging."

"There is no way. Even if you know how to forge, it is still difficult."

Even if they understand the titanium alloy synthesis technology, the workers still find it quite difficult because no one has ever tried this forging before.

"Even if it's difficult. But I have to ask, can this be done?!"

"No, let's break up."

Already impatient!Factory Director Liu couldn't bear it because he had to discuss a titanium alloy technical drawing for more than a day.

For this reason, I just want to ask once, what should I do?

"Don't! Let's forge."

"Let's try and stop talking."

"Me too, give it a try."

Afraid of offending Factory Manager Liu, the workers all agreed to forge titanium alloy steel.

Work hard to forge it according to the method given by the person who entrusted it.

"It turns out that everything is broken up like this! Everyone must forge titanium alloy steel and do it according to the method given by others."

Factory Director Liu told them to do it immediately.

"Yes!" several workers responded in unison.

At this time, Baihong Manor.

Li Youchen regained a more detailed understanding of titanium alloy technology.

The production of turbocharging requires titanium alloy materials to be completely isolated from the air, blocking the air, supercharging, forming a high-pressure gas that enters the combustion chamber for combustion, producing high-temperature and high-pressure hot gas that is released from the rear nozzle, and finally converted into power for propulsion. .

High temperature resistance is one thing. If the operation of the turbofan engine itself generates a high temperature of thousands of degrees, it will easily dissolve the non-alloy material of the turbofan engine itself, which will be very troublesome.Only titanium alloys that can withstand high temperatures of more than [-] degrees Celsius can sustain the continuous operation of turbofan engines to generate kinetic energy at temperatures of over [-] degrees Celsius.

High temperature resistance is a characteristic, not afraid of high temperatures.

If the titanium alloy is manufactured by a smelter, it will easily burst if the quality effect is not achieved. The process is of poor quality and prone to cracks.

The design drawing of the turbofan engine has been drawn.

Li Youchen looked up and down and checked carefully. The content was drawn using formula calculations. There was absolutely no problem with the content on the drawing.

Only by waiting for the titanium alloy steel to be delivered can we start manufacturing.

In terms of time, you still need to wait.

-

When I returned to school, I also brought the manufacturing drawings of the turbofan engine back to school.

Just as Li Youchen wanted to enter the school gate, he was stopped by the guard.

"Young man, don't come close! During martial law, you are not allowed to come here without permission."

The doorman said hurriedly.

Take a wolf guard and take precautions.

"Uncle, it's me, I'm a student here, and what's the situation with the sudden martial law in the school?"

Li Youchen asked and closed the doors, as if entry was prohibited during martial law.

The guard uncle wiped his eyes, took a closer look, and suddenly realized:
"Li Youchen! It turns out to be your boy."

"No, why did you go out? Why did you choose to come back at this time in the afternoon?"

Li Youchen sweatdropped, "I still want to ask you, uncle? What is the situation under martial law?"

The guard opened the door for him, let him in, and told him:
"Several cases of missing persons occurred in several state-owned and private universities in Chang'an City, which started to cause a stir in the surrounding area. The maintenance police station and relevant departments took action to pay attention to the missing cases of university personnel. The school received relevant reports Special notice, martial law has been decided, and no one will be allowed in or out of the Polytechnic University for a short period of time."

"You are a student of the Polytechnic University. Please return to school as soon as possible. You are not allowed to go out at will."

Li Youchen walked in, turned around and squinted, and the doorman closed the door.

It seems that it is really related to the high-paying recruitment scam.

In his previous life, he didn't notice at all that this time it really caused a case of missing persons... Li Youchen wanted to call the police to deal with it, and it turned out that there was nothing wrong. At least, the police station took this case seriously.

"When did people start missing?"

Instead, Li Youchen asked seriously.

"Just in the past few years, there have been nearly a dozen missing persons."

The police news that the guard heard was probably as simple as that.

Li Youchen crossed his arms and thought:

In the past few years, depending on the situation, an invisible hand has reached into the campus a long time ago, specifically targeting talented college students, teachers, etc.

Just like Max, using so-called high-paying recruitment to lure people into a trap.

However, several universities in Chang'an City have implemented the strictest martial law.

I'm afraid that in the past few days, I can't leave school at will.

The production of turbofan engines and model machines is expected to take a few days.
