Chapter 141： Changan Power

The genius remembers the address of this site in a second: [New]https://Fastest update! No ads!

Li Yun's shocked eyes gradually recovered, and she stared at him with wide eyes.

"You also know that you are afraid? How much does an eight-meter-long plane weigh?

Take the small one as an example, the small one weighs 1.6 tons, the big one must not have a total weight of 3 tons? "

Li Yun's tone was full of disbelief, and she had already guessed the weight in the heavier direction, and three meals were not considered light.

But she still didn't guess correctly. After she said the guessed data, she inserted a sentence at the end.

"Hey, the total weight of the things I designed is 5 tons, okay, okay, I won't talk about it,

Mr. Yan is now instructing people to carry the eight-meter frame,

I don't know where to do the later assembly work,

I'm going on a business trip again this time, so it shouldn't be too long. "

While the two were talking, Yan Hang was loading parts into the car with a few soldiers.

In the following time, he didn't stay with Li Yun all the time, and even chatted with Liu Xiaodong and Guo Shugui.

By noon, under the hard work of many soldiers, all the parts were loaded on the car,

Cover the tarpaulin of the carriage, and no one knows what is in the carriage.

After loading the car, Yan Hang greeted Li Zhenhua to leave, and he was taken away by the old man before he even had lunch.

Saying farewell to Li Yun and the others, sitting in the passenger car of the military card, the military card drove off into the distance.

The army card drove all the way to the south, and Li Zhenhua, who was sitting in the car, also guessed that this should be to transport his parts to Hongdu.

As expected, the army card went south directly after getting on the expressway.

And he also got the exact answer from Yan Hang, that is to go to Hongdu factory, and in Hongdu, they have already vacated a workshop for this plane.

Sitting on the road, he fell asleep staggeringly, and when he opened his eyes again, it was completely dark outside.

Looking at the car that was still driving, he was not sure where he was now.

Anyway, after knowing where the destination was, he didn't ask at this time, and the car drove on the road for another four or five hours.

When the car got off the highway, he also checked the time, it was already twelve o'clock at night,

This time point is actually about the same as the time when he first delivered the engine to Hongdu factory and got off the high speed.

Junka took him and the parts on the car, and drove in through the main gate of the Hongdu factory.

After walking for a while, he still knew a little about the Hongdu factory, and felt more and more wrong.

Then turned on a road at Junka, stopped at the end of the road, passed another checkpoint, and finally stopped at the door of a workshop.

It seems that this is the destination, and then he got off the military card,

Looking at Yan Hang who jumped out of the car in front, he walked over to the old man.

"Old man, what kind of place is this? Is it still in your company?"

Yan Hang was not surprised by this question, he guessed it would be asked from the beginning.

"This is the factory area for military aircraft manufacturing. The places you have been to before are all civilian manufacturing factories.

These two places are separate. The engine and flying boat you provided before can only be regarded as the periphery of Hongdu.

Our main business is not small civilian aircraft, but fighter jets. Don't forget that we are a state-owned military equipment manufacturing factory. "

After Yan Hang's explanation, he also understood.

When they arrived at the place, their work could begin. Together with many soldiers and technicians from the Hongdu factory, he began to unload various parts from the car.

After more than two hours of careful unloading, they finally unloaded all the parts on the car,

And this time, under the command of Li Zhenhua, the various parts of the aircraft were sorted and put away in the workshop.

After they put all the parts of the plane in place, these soldiers didn't rest, and drove back overnight to report to duty.

After these soldiers left, only a dozen technicians from Hongdu, Yan Hang and Li Zhenhua were left in the workshop.

As for Gu Changkong, the chairman of Hongdu, he had already started various arrangements when he came back, and now he doesn't know where he went.

Yan Hang looked at the parts in front of him by category, feeling very uneasy in his heart.

When he loaded the car, he had already seen the processing level of these parts and the materials used for the parts.

And I also went to see the parts of the engine in particular, carefully studied the materials used for the parts,

Through his many years of experience, he already knows that many of the engines are made of single crystal metal alloy materials,

This also let him know why the engine of the 3.5-meter small plane can emit blue tail flames.

The material is good enough to bring out the advanced engineered structure to the level it should.

Just looking at the materials of these parts, you can know that there are still many secrets that have not been uncovered in Li Zhenhua, a young man.

From this point of view, this kid didn't just build two planes.

Yan Hang touched the one in front of him, which was less than 20 centimeters long, and asked Li Zhenhua without answering.

"Zhenhua, what I'm touching now should be a blade on the engine.

Can you tell me about the engine you designed? And the material used for this blade is not simple! "

At this moment, there were only the two of them left in the workshop, and all the technicians from the Hongdu factory had gone back.

"Well, it's a blade on the fan in front of the engine,

The engine I got out has a total length of 250 cm and a diameter of 65 cm.

The weight is 300 kg, its thrust-to-weight ratio has reached 12, and its total thrust has reached 3.6 tons.

It is more than twice the thrust of the engine on my small plane. The total thrust of that small engine is only 1.4.

It was because of the calculated thrust table that I made that small plane. "

I had some speculation about this eight-meter plane, but I didn't expect his thrust to be so strong.

"3.6 tons of thrust? You are really good at it. I remember that the afterburner thrust of turbojets is only 3.8 tons.

Your engine, which is only 2.5 meters long, can be used as the power of J-5 in terms of thrust.

You really know how to play, you can play so well,

That's enough, let's do this for today, and tell me about the materials tomorrow, it's getting late, you can go to the office with me to deal with it overnight,

We will start work tomorrow morning, and strive to get your plane out as soon as possible. "

Li Zhenhua followed Yan Hang to his office. Although he had dozed off on the way, he was still a little tired.

Not long after lying down on the sofa, he fell asleep in a daze.

Early the next morning, the sun shone on his face, and he woke up after a while,

After eating with Yan Hang in the cafeteria of Hongdu factory, he returned to the workshop.

The technician in the workshop who helped move things yesterday has already come here and waited.

"Zhenhua, these are the ten best masters in our factory. They will help us assemble your plane together, which will be faster."

Yan Hang briefly explained to him, Li Zhenhua also nodded, it would be nice to have someone to help,

As for whether to keep the Hongdu Factory a secret at this time, he directly forgot about it. He believed in Yan Hang, and believed that the Hongdu Factory would not do that in some matters.

The assembly started, and these people also belonged to him. The engine was still the first to start assembly.

With the help of these people, the assembly speed is much faster than his own.

Of course, on some key parts, he still did it himself,

With the help of the analytical eye, the speed of assembling the engine was quite fast. In just two days, a turbofan engine was presented in front of everyone.

Yan Hang looked at the engine in front of his eyes, and couldn't help feeling emotional in his heart.

Who would have thought that a turbofan engine that is only 2.5 meters long and 65 centimeters in size can provide 3.6 tons of thrust?

Such a small engine with such a huge thrust can not only be used on his current plane.

For example, the drone of Rainbow Five has a take-off weight of more than 3 tons. Such a small engine can completely make it fly.

Of course, this is just a metaphor. After all, Rainbow Five uses a turboprop engine, and this engine is a turbofan.

But around this engine, new models can be developed. As long as the thrust is high enough, it is still possible to design a new aircraft.

The engine has been assembled, although Li Zhenhua has obtained all the calculated data, but Yan Hang still needs to do a test,

Then Yan Hang contacted Changan Engine Company, and their engine will be shipped over for a test run.

The engine's next itinerary was arranged, and he didn't take care of these things. He continued to assemble the second engine.

"Old man, send this engine to Chang'an, let's go there first, let them do a comprehensive test,

I made enough parts for this engine to assemble four, we will use two on the plane,

Now that is enough, I will get out the remaining three and leave one as a spare part. "

Yan Hang arranged for the engine to be transported away on a military transport plane. Chairman Gu Changkong took the engine with him personally.

After the engine left, he put all his body and mind into the assembly of the eight-meter aircraft.

Gu Changkong took the packed engine, first went to the nearest military airport, and took the Yunba waiting here.

Then flew towards Chang'an.

On the side of Changan Power, the department that manages the test bench received an outsourcing test task early in the morning.

The data sent over made these staff all think that someone was joking with them, UU Reading

It is only a small engine of 2.5 meters, with a total weight of only 300 kilograms, but the thrust can reach 3.6 tons, which is outrageous no matter how it sounds.

What they don't know is that there is an engine one size smaller than this one that has already flown into the sky!

The unit that sent the outsourcing was Hongdu Factory, and this brother unit couldn’t make fun of this kind of thing.

So Changan is also waiting, waiting for the engine to arrive, they want to see what is going on with the engine.

Finally, after ten o'clock, Gu Changkong's Yunba landed at the airport, and then the engine was installed on the military card and transported to Chang'an Power.

After more than ten minutes, the staff of Changan Power finally saw this small engine.
