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

"You also know to be afraid? How heavy does an eight-meter plane have to be?

Take the small one as a column, the small one weighs 1.6 tons, and the total weight of the big one must not be 3 tons? ”

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

But she still didn't guess accurately, and after she said the guessed data, she interjected a sentence at the end.

"Hehe, the total weight of the thing I designed is 5 tons, okay, okay, I won't say it,

Old Man Yan is now directing the people, carrying the eight-meter one,

The work of the rear assembly, I don't know where to carry it out,

I'm going on another business trip 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 chatted with Liu Xiaodong and Guo Shugui about some things.

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

The tarpaulin of the trunk is covered, and no one knows what is inside the compartment.

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

and Li Yun said goodbye to each other, sitting in the passenger seat of the military card, and the military card drove into the distance.

The military truck 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, after getting on the highway, the military stuck on the highway and went directly south.

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

He sat and sat on the road, staggering and falling asleep, and by the time he opened his eyes again, it was all dark outside.

Looking at the car that was still moving, he couldn't tell where he was now.

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

The car got off the highway, and he also checked the time, it was already twelve o'clock in the evening,

This point in time is actually about the same time as the first time he sent an engine to the Hongdu factory and came off the highway.

Jun Kara took him and the parts on the car and drove in from the main gate of the Hongdu factory.

After walking for a while, he still has some understanding of Hongdu Factory, and he feels more and more wrong.

Then he turned a road at the military card, then stopped at the strength of the road, passed another checkpoint, and finally stopped at the door of a workshop.

It seemed that this was the destination, and then he stepped down from the military card.

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

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

Yan Hang was not surprised by this question, and he guessed that he would ask such a question at the beginning.

"This is a factory for military aircraft manufacturing, and the places you have been to before are all civilian manufacturing plants.

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

Our main business is not small civilian aircraft, our main business is to build fighter jets, and let's not forget that we are a state-run military equipment manufacturing plant. ”

After Yan Hang's explanation, he also understood.

When they arrived, their work could begin, and he, along with many soldiers and mechanics from the Hongdu Factory, 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.

Moreover, this time, under the command of Li Zhenhua, the parts of each part of the aircraft were classified and placed in the workshop.

When they put all the parts of the plane in place, these soldiers did not rest, and drove back to report back overnight.

After these soldiers left, there were only more than ten technicians from Hongdu left in the workshop, as well as Yan Hang and Li Zhenhua.

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

Yan Hang looked at the parts in front of him, and he was very uneasy in his heart.

When he was loading the truck, he had already seen the processing level of these parts, as well as the materials used in the parts.

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

Through his years of experience, he has learned that many 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 a blue tail flame.

If the materials are good enough, the structure of the advanced design can be brought out to the level it should be.

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

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

Yan Hang touched the blade in front of him, which was only less than twenty centimeters, and asked Li Zhenhua without replying.

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

Can you tell me about this engine you designed? And the material of this blade is not simple! ”

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

"Well, this is a blade on the fan in front of the engine,

The engine I made is 250 centimeters in length and 65 centimeters in diameter.

The weight is 300 kilograms, his thrust-to-weight ratio reaches 12, and the total thrust gets 3.6 tons.

It's more than twice the thrust of the engine on my small plane, and the total thrust of that small engine is only 1.4.

It was because of the thrust table that I calculated that I was ruthless that I was able to get that little 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, I remember that the afterburner thrust of the turbojet five is only 3.8 tons, right?

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

You're really good at playing, and you're still so big,

Okay, let's do this today.,I'll tell me about the materials tomorrow.,It's not too early.,You go to the office with me to deal with it for a night.,

We'll start work early tomorrow morning and try to get your plane out as soon as possible. ”

Li Zhenhua followed Yan Hang to his office, although he had already taken a nap on the way here, he was still a little tired.

Not long after lying down on the couch, I fell asleep in a daze.

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

followed Yan Hang to eat in the canteen of the Hongdu factory, and then returned to the workshop.

The technician in the workshop who helped move things yesterday has already come here to wait.

"Zhenhua, this is the ten most skilled masters in our factory, they help us assemble your plane together, so that the speed is faster."

Yan Hang explained to him simply, Li Zhenhua also nodded, of course it would be good to have someone to help,

As for whether to keep Hongdu Factory secret at this time, he directly left it behind, he believed in Yan Hang, and believed that Hongdu Factory would not do that in some things.

The assembly began, and these people were all under his command, and the engine was still the first to start the assembly.

With the help of these people, the assembly speed is much faster than he did by himself.

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

With the help of the analytical eye, the assembly of the engine was quite fast, and it only took two days for a turbofan engine to be presented in front of everyone's eyes.

Yan Hang looked at the engine in front of him, and couldn't help but sigh in his heart.

Who would have thought that a turbofan engine measuring only 2.5 meters long and 65 centimeters would be able to provide 3.6 tons of thrust?

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

For example, the Rainbow Five drone, his take-off weight is more than 3 tons, and such a small engine can fully make it fly.

Of course, this is just a metaphor, after all, the 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 feasible to design a new aircraft.

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

Then Yan Hang contacted Chang'an Engine Company, and their engine will be transported over for test runs.

The rest of the engine was arranged, and he didn't care about these things, and he continued to assemble the second engine.

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

I've made enough parts for four of these engines, and we're going to use two of them on our planes.

Now it's completely enough, I'll get the remaining three out later, and the remaining one as a spare part. ”

The engine was arranged by Yan Hang to be transported away on the military transport plane, and Gu Changkong, the chairman, personally took the engine there.

After the engine was gone, he devoted his whole body and mind to assembling the eight-meter aircraft.

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

Then he flew towards Chang'an.

On the side of Chang'an Power, the department specializing in the management of the test bench received a task of outsourcing testing early in the morning.

The data sent over made these staff unanimously think that someone was joking with them.

It's just a small engine of 2.5 meters, with a total weight of no more than 300 kilograms, but the thrust can reach 3.6 tons, how outrageous it sounds.

What they don't know is that there is a smaller engine that has already taken to the sky!

The unit that sent the outsourcing is Hongdu Factory, and it is impossible for this brother unit to joke about this kind of thing.

So Chang'an is also waiting, waiting for the engine to arrive, they want to see what the situation of this engine is.

Finally, at more than ten o'clock, Gu Changkong's Yunba landed at the airport, and then the engine was loaded onto the military truck and transported to Chang'an Power.

More than ten minutes later, the personnel on the side of Changan Power finally saw this small engine.
