Because Wang Hongmei performed too well last night, she worked too many overtime, so she didn't have a chance to watch the plane the next day.

The day before Chinese New Year's Eve, Liu Hai drove Wang Hongmei to Kyoto, no one else, Wang Hongmei's son Liu Hai would not take the initiative to contact, and the grandparents were very distressed.

Don't look at Liu Hai's hometown is not far from Kyoto, but few people here come to Kyoto.

First of all, you must have a letter of introduction when you go out at this time, and in addition, food and accommodation outside are not cheap, even the fare is not cheap, especially for people in rural areas.

A few years ago, Liu Hai didn't have the opportunity to take Wang Hongmei to Kyoto for a walk.

After coming to the factory, he registered at the factory gate, and then Liu Hai went to ask the factory director for instructions.

Of course, Sun Aiguo agreed, there is nothing secret about this kind of small plane, and so many people around look at it every day.

"I didn't expect Liu Hai, this little sister-in-law to be quite handsome!" Sun Aiguo saw Wang Hongmei and muttered in his heart.

But looking back, Liu Hai is not a bad person.

For the first time, Wang Hongmei saw people with guns standing guard and such a large factory, and it took a while to drive in the factory to an open place.

"Section Chief Liu!"

"Section Chief Liu!" The open area is the airfield, and this small plane does not need to have good take-off conditions, and it is paved with asphalt.

"This is my relative, I want to come and see the plane!" Bangs took out a few packs of cigarettes, one for each person.

"Section Chief Liu is polite."

"Section Chief Liu is the man!" Liu Hai behaves in the factory, and he does a very good job, even if he is an ordinary worker, he will not say that he is a cadre.

Wang Hongmei is curious about everything, first of all, the large factory buildings, the tall electric poles, the tall chimneys, and the tall buildings in the distance.

Wang Hongmei looked at the plane in front of her, and couldn't believe her eyes, this didn't look big.

Liu Hai let Wang Hongmei sit in the co-pilot seat, got into the main driver's seat, and then took Wang Hongmei up to fly for five minutes.

"My legs are so soft." After getting off the plane, Wang Hongmei felt that she was unsteady on her feet, she was too tall just now, especially when she looked down from above.

"It's the first time for the average person." Liu Hai greeted the staff at the scene again, and helped Wang Hongmei to get into the van and leave.

"Who is this Section Chief Liu?"

"This woman looks like she's from the countryside, right?"

"Section Chief Liu must have returned to his hometown, maybe it's some relative at home."

"Don't ask around, where can I find a cadre like Section Chief Liu?"

"That's it! I can't gag you cigarettes. ”

"You can fly a plane!" Wang Hongmei sat in the van, and finally cleared up in her mind for a while, looking at her bangs in disbelief.

"I have a good relationship with the factory director, so it's good to come and learn if I have nothing to do!" Bangs smiled.

Then he took Wang Hongmei to the mall here for a walk.

Liu Hai also has a lot of tickets in his hand, but Wang Hongmei is too expensive, and he also said that he can't dress up too enchanting in the countryside.

In the end, I bought a pound of White Rabbit toffee.

Liu Hai used to be a cadre who felt a little bit of power in Wang Hongmei's heart, just like some township cadres who were scumbags.

I didn't expect to feel unusual when I came here in person, and there were people who greeted me cordially wherever I went.

That kind of tone and demeanor is definitely not a perfunctory greeting, a casual greeting.

The key is that Liu Hai can still fly a plane, which subverts Wang Hongmei's imagination, although he knows that Liu Hai has been riding a bicycle for a long time, driving a motorcycle, and driving a car.

But this is an airplane, although this plane is different from what I imagined, but it can indeed fly, and it flies high and high.

Back in the village, Liu Hai beat wild boars twice and a lot of rabbits and pheasants at the behest of the village chief and captain.

Wang Hongmei didn't come to Liu Hai's side at night, and Liu Hai went into the aircraft carrier space to design the shield machine.

At this time, the shield machine was not complicated, because it was semi-automatic, and in the 19th century, the West used the shield machine. But it was simpler at the time.

Think of the EPB as a big drill bit, but the scrap from this bit is conveyed through a conveyor belt in the middle of the bit.

The TBM stops one metre forward, then manually moves the hydraulic equipment and lays the modules poured outside around the tunnel.

This kind of thing is more troublesome, and it still needs a lot of workers, but at the current level of working conditions, if you want to engage in full automation, it will definitely not work.

A 10-meter diameter EPB is very large, but the larger it is, the easier it is to design and maintain.

When the shield machine is excavating, the tunnel wall is directly supported by hydraulic equipment in the back, and when the tunnel reaches a position of one meter, the shield machine stops.

The equipment supporting the tunnel wall at the back had to be moved one meter to the front, and the vacant space had to be filled with poured concrete modules.

It's not complicated to say, but it's still technically difficult to manufacture.

It contains multiple systems, such as pressure systems, air systems, cooling systems, and so on.

In fact, to put it bluntly, the most important thing is the hydraulic system, fortunately, the motorcycle factory has achieved very good results in hydraulic equipment in recent years.

Of course, it is also beneficial for Liu Hai to take Wang Hongmei out for a lap of the plane, that is, when working overtime, he is obedient and has experienced some new tricks.

"You'd better hurry up and find another one, don't come back and toss me hard." On the third day of the Lunar New Year, Wang Hongmei opened her eyes and looked at the time, it was already past ten o'clock, and she pinched her bangs twice angrily.

"Anyway, it's snowing heavily outside, do you want to sleep for a while?" Instead, he took it out with his backhand and said shamelessly.

Then Wang Hongmei pulled away the bangs, put on her clothes and said: "That's you from the city, and we countrymen have to work in the snow." ”

Seeing Wang Hongmei leave, Liu Hai didn't have the idea of sleeping, and got up with a grunt and found that the snow outside was heavier.

"Do you want to find another one?"

"It's a little lonely to be alone at night in the city?" Bangs was thinking about this in his head.

"Forget it, wait until this wind passes." Then, Bangs put this idea aside again, and it was a big deal to drive back at night later.

After Liu Hai cooked and ate by himself, he closed the door, and then entered the aircraft carrier space to design the shield machine.

One of the reasons why these large machines are complex to design and technically difficult in this day and age is that they involve a large amount of calculations.

Each set of data has to go through countless calculations, and with advanced computers, just a few keys are needed.

If there is a problem with the calculated data, it can be changed accordingly.

These data are copied on the notch, including some erroneous data that needs to be changed.

Semi-automatic is not as complex as fully automatic in terms of control, but it requires workers in each position to operate by observing the instrument.

"Who should the twin-engine transport plane copy?"

"C46 or Il-14?" In his spare time, Liu Hai is pondering the twin-engine transport plane.

It's not that Bangs doesn't want to make a turboprop now, because it's simply not possible.

The faster the aircraft and the greater the load, the higher the demand for the manufacturing level of the aircraft.

Not to mention anything else, just the tens of thousands of tons of integrated beam forming technology, without this technology, even if it is to make a turbofan engine, it is not of much use.

Because the overall structure can't withstand such a large force at all, it is better to honestly walk the piston engine.

Because of the time difference between space and reality, on the sixth day of the Lunar New Year, Liu Hai completed the first draft of the shield machine.

That's right, Liu Hai printed out the first draft of the shield machine in the space of the aircraft carrier, and then copied it by hand.

Wang Hongmei watched her bangs draw on the table, and she was holding the soles on the side, and now many people wear cloth shoes, which are basically made by themselves.

"You guys are also working hard, staring at so many dense numbers every day, I get dizzy after looking at it for a while." Wang Hongmei looked at her bangs and packed up her things before she spoke.

"Get used to it!" Bangs put the drawings and various tools separately.

"You're going back tomorrow?" What does Wang Hongmei say about bangs, she likes and hates it.

I like this man who is younger than myself, he will hurt people, and every time he comes back, he brings good things, and he doesn't lack anything in food and clothing.

In this era, as long as he is a man who cares about his family, he is a good man.

In fact, even in the back, as long as it is a man who takes care of his family and does not mess around outside, he is a good man.

Of course, some women in later generations are too demanding.

What I hate is that the night is endless, just like the donkey of the production team.

"When I go back, there are still a few people in the city who want to move around, and after a bit of walking, I will go to work." Liu Hai nodded, it's been seven or eight days since I came back this time, and the main thing is that everything that should be done is almost the same.

"I made you two pairs of cloth shoes, and I will take them with you when I leave tomorrow, and I won't make them for you in the first two years, because I am afraid that your lover will have an opinion on you." Wang Hongmei pointed to the two pairs of cloth shoes next to her.

Liu Hai nodded, Wang Hongmei is good at this, she is self-aware, and she will not interfere in her life indiscriminately.

The next morning, after nine o'clock, I got up to clean up my bangs, and then went out.

Bangs first tie the snow chains of the car, because the road is definitely slippery on the successive heavy snow.

There were more pedestrians on the road, but Liu Hai didn't think about accosting others.

Along the way, I came to the factory very smoothly, and first put the drawings of the shield machine in the cabinet.

Then I walked around the various workshops, and the several workshops under the jurisdiction of Liu Hai did not have a holiday.

The 2,000 workers in the factory who had gone southwest had already left, and together with their families, it would be difficult to see each other again, thousands of kilometers away.

The motorcycle factory also officially ended the production of assault vehicles, freeing up equipment and other products to produce other products.

"Xiao Liu, why do you go to work so early?" Liu Hai came to the factory director's office, and Sun Aiguo asked in surprise.

"There's nothing going on in my hometown, it's just the tunnel boring equipment I told the factory director last time, and I want to test and manufacture it here." Bangs opened his mouth to speak.

"You can do this boldly." Of course Sun Aiguo didn't know that Liu Hai had a big guy.

"By the way, last time you said you wanted to visit the plane, and there happened to be a scrapped plane, do you want to tow it back?" Sun Aiguo remembered another thing and asked.

"You don't have to drag it back, right? I'll just go and have a tour. Of course Liu Hai was very happy to hear this.

"Then I'll take you there in the afternoon." Sun Aiguo immediately made a decision.

In the afternoon, Liu Hai took the three cadres of the maintenance department, and then brought two tape measures, to the airport south of Kyoto.

“C46！” In a corner of the airport, Liu Hai saw the double-engine plane and recognized what kind of plane it was, which was the main transport plane of the Hump route back then.

The performance of this aircraft has been tested, and there are many improved models of this aircraft, and there are too many to count.

"This can be converted into a gunboat machine."

The people at the airport were a little dumbfounded, and the superior just said that someone was going to visit today to see the scrapped plane.

Unexpectedly, after greeting people, several young people took a tape measure and walked around the scrapped transport plane.

The people present are eager to say, want specific data to ask us?

However, the leader did not explain, and no one dared to say it.

"Measure the entire length of the plane first."

"Then measure the diameter of each length separately."

"The size of the tail, the size of the wing."

"The size of the internal structure, the structural pattern."

Liu Hai took the three major King Kong of the maintenance department to measure the size of the aircraft, and at the same time explained to several people what data to measure.

Sun Aiguo watched a few people busy on the side, and chatted with the person in charge of the airport here while smoking.

The person in charge of the airport also knew Sun Aiguo's factory and was able to manufacture small planes.

"It would be great if you could make this kind of plane."

"Now we have just over 100 transport planes, all of which are imported."

"Among them, there are old and beautiful people in the past, and there are big brothers, and the maintenance is very troublesome."

"None of these transport planes in the United States can fly, but there is no way, there must be a force to maneuver quickly."

At this time, the transport planes we imported were to ensure the rapid mobility of at least one regiment in China.

So Big Brother's plane and Lao Mei's old guy's plane, as long as they can fly, everything must be used to fly.

Of course, if you import someone else's plane, you can't fly as casually as you can make it yourself.

"Are there any scrapped engines here?" When Sun Aiguo heard this, he asked.

"If you want it, I'll send you one later."

"Let's get back in touch!" Sun Aiguo didn't agree, because he had to listen to Liu Hai's opinion.

"There's Il-14 over there, do you want to take a look?" The person in charge of the airport asked again, pointing to the hangar over there.

"Look!" Sun Aiguo nodded immediately.

The person in charge of the airport opened the hangar, and Liu Hai took the three cadres of the maintenance department to measure it with a tape measure, and then record the data.

"Xiao Liu, are you sure about the big plane with two engines?" On the way back, Sun Aiguo asked while driving.

"It's not a big problem, the power system is completely fine, today I came to test its appearance, the appearance of the aircraft involves aerodynamics, fluidics, mechanics and so on."

"You can't design a good aircraft without a wind tunnel, so we have to copy their aircraft shape, and designing an aircraft shape alone requires too much equipment."

"If our planes look like theirs, they won't think we're highly technological." Bangs probably explained.

"So is our airport going to be expanded?" When Sun Aiguo heard Liu Hai's words, he thought of the big plane taking off in his factory and asked.
