Chapter 707 Safety Story (Second Update)

"Thank you for your hard work." The junior sister enjoyed her senior brother's attentive attitude.

"You are the one who works harder." Liu Hai replied with a smile.

"It's a pity that the world doesn't know about your achievements, but now I am successful and famous." The junior sister felt somewhat aggrieved for Liu Hai.

Liu Hai chuckled and said: "Who among us is following the other? It took ten years to cross the same boat, and a hundred years to sleep together. In fact, I never thought that I would be where I am today."

"Speaking of when I was herding sheep in the village, my biggest hope at that time was to eat cornbread every day."

"In fact, not only me, but everyone at that time, including everyone in our village, could not have imagined that we would be able to live such a life today."

"You have a lot of credit for this. You have made a very important contribution to the development of our country's industrialization." The junior sister nodded after hearing this.

"That's what I say, but without the country providing a stable environment and without the contributions of other worker brothers, my invention alone will have no effect."

"There has never been a shortage of geniuses in history, and there has never been a shortage of people with ideas. It is not the heroes that create the era, but the era that creates the heroes. If we go forward 50 years, even if I have any ability, in that turbulent environment , I can only go with the flow. "Liu Hai has seen a lot of things in his life.

In order to further increase the security work of the confidential department, all employees of the confidential workshop, including all persons in charge, took a minibus.

When the pilot gives a takeoff signal, all computer systems must recognize it. What state should each component of the takeoff aircraft be in?
Then what kind of status is required for landing? This is all recognized by the telex signal computer and then passed to the control unit.

Liu Hai originally thought there would be a mistake, but then the factory director said the person's last name: Yu!
Liu Hai then remembered that historically, it seemed that this guy only went abroad in the mid-80s.

However, the fly-by-wire flight controls of different types of aircraft are very different.

"They are all a bunch of rubbish." Half an hour later, Sun Aiguo yelled.

"Senior brother, do you know what I admire most about you? It's that you take all personal honors too lightly. If it were someone else who had achieved your level of success, I don't know how proud they would be."

Other departments can only slowly explore how many sensors are needed on the wings. This can only be tested step by step.

Of course, entering and exiting the security check is inevitable.

It cannot be said that a leader does not accept security checks. This is impossible.

"Thank you for the compliment, junior sister." Liu Hai smiled.

The key is that this person is also affiliated with the Kyoto Security Department and is also a cadre.

"Liu Gong!"

The main reason why this ground test took so long was the fly-by-wire flight control system.

The security personnel responsible for protecting Liu Hai immediately separated Liu Hai from other people.

At the same time, the computer also needs to use sensors to identify what the current posture is, otherwise an accidental identification error will cause trouble.

The senior brothers and sisters whispered a lot.

Even Sun Aiguo hurriedly followed Liu Hai and ran to the side. On the contrary, the other leaders who followed him looked confused.

But many people ignore that it is the environment that makes these people successful. Without a large environment, no one can do it.

Liu Hai got up early the next day and came to the factory because today was the first day of flight testing for the small jetliner.

Especially for long-term flights, the advantages of the fly-by-wire flight control system are even more obvious.

The fly-by-wire flight control system is even more powerful when used in fighter jets because it can reduce the pilot's operational difficulty and give the pilot more time to think.

Of course, Liu Hai did it quickly. He knew where to place which sensors, and where to place the computer system, and then what calculation model was needed?
What's going on with the flight attitude control system?

This tiny camera is placed at the bottom of the cigarette box.

"Liu Gong!" These leaders greeted Liu Hai one after another when they saw Liu Hai.

We were originally blank in this aspect, but Liu Hai has laid a foundation this time.

"Director!" Go to the aircraft test ground and take a unified minibus.

It turned out that just when entering the airport security check, it was actually discovered that a person was carrying something that he should not be carrying. On the surface, it was a box of cigarettes and a lighter, but there was a miniature camera inside the cigarette.

There is also the electrical signal control system identification of the motor that controls the wing. To what extent does the motor need to run? To what state do you control the wings?
These require computers to recognize the pilot's operating signals and then transmit them to the control units on the wings.

When they arrived at the airport, Liu Hai and others got out of the car and went through security check.

Liu Hai also moved quickly. When he saw the security personnel separating him, he quickly hunched his neck and found the nearest cover position.

"Leader!" There were other leaders in the car.

Some people think they are awesome and think they are leading the era.

This is also the first aircraft in my country to adopt a fly-by-wire flight control system.

And there is only one cigarette in this cigarette box, the others are full, but the other cigarettes are half-cut.

The fly-by-wire flight control system is currently a blank in our country. Although there are departments working on it in the past, they are not doing it as fast as Liu Hai.

"If you were with everyone else in the factory, they wouldn't know you were any different."

Even the leader who brought this person here was confused. This leader was still a leader in charge of the aviation industry, but he was just a deputy.

Therefore, in terms of testing, it is necessary to conduct repeated tests to ensure the safe operation of the fly-by-wire flight control system.

Because it is experimental in nature, everything is moving forward through trial and error, although the bangs have already given me a foundation.

Liu Hai is in 2020, but do you know what some project leaders in our country are like? There seems to be a chief engineer of a certain type of missile? Or even the head of some security department?
Sometimes there are some things that just can't stand to be remembered. Liu Hai had just passed the security check, but he didn't expect that there would be a commotion behind him.

For example, if the plane wants to turn right, which parts should be moved? How much to move.

You must know that this person's level is not low. After catching him, Sun Aiguo immediately asked the factory security office to give him an answer within an hour.

As a result, within 20 minutes, the security office came to report to Sun Aiguo.

Sun Aiguo immediately asked the security department to catch this person's person, no matter who was involved.

The security department of Dongfang Heavy Industries is of a very high level, let alone weapons and equipment.

It turns out that the test flight site of Dongfang Heavy Industries has been stared at by others for a long time.

So this time the ground test of the small jet airliner was watched by others.

And this guy who was caught was coaxed and corrupted by some people abroad because he was dissatisfied with his low salary.

He also promised that as long as he can take a photo this time, whether it is an airplane or other staff members, a photo will cost 500 US dollars, and the guarantee is 1 US dollars, which means that even one photo will cost 1 US dollars.

The flight test of the small jet was delayed by two hours

But there was no way not to test it, because of the weather, so I chose today.

Liu Hai didn't need to worry about this matter at all. Even the factory director continued to watch the flight test as if nothing was wrong.

The two pilots inside the small jetliner were very nervous. The test pilot, the pilot and co-pilot, listened intently to the test director's orders.

The main pilot uses fly-by-wire flight control. Once there is a problem with the fly-by-wire flight control, the co-pilot immediately uses the hydraulic control system.

There is nothing nervous about Liu Hai. Anyway, if there is a problem with the fly-by-wire flight control, just use the hydraulic control system immediately.

What Liu Hai designed for this test flight was that the hydraulic control system had a higher priority than the electric wire.

That is to say, as long as the hydraulic control system intervenes, the telex system will directly give up any operation by default.

When it comes to flight control, system conflict is an absolutely fatal act.

Liu Hai knows that there have been many air crashes in his life. Originally, the pilot wanted to pull the plane up, but the system had to push the plane down.

This is basically a matter of system permission priority.

The same problem also exists in the new energy vehicles behind. While braking, then accelerating.

In fact, you can set a priority, that is, as long as you step on the brake, even if your other foot is on the accelerator, the system should default to not pressing the accelerator.

As for stepping on the wrong accelerator, it can also be prevented, because Liu Hai has a navigation system when crossing. If it detects that the vehicle status is abnormal, then you can completely relax the accelerator.

For example, in an urban road environment, if the number exceeds 80, the system can intervene.

After all, when the bangs are crossing, the throttle is an electronic control signal, not that kind of mechanical control.

Liu Hai was watching from the side and did not personally give the order.

The first small jet took off slowly from the runway under the attention of many eyes.

Everyone breathed a sigh of relief when they heard that the plane had reached the predetermined altitude and everything was normal. This was at least half the battle. The aircraft then conducted a series of tests in the air according to instructions, such as climbing and turning.

After flying in the air for 10 minutes, it started to land.

When the plane lands completely and the pilot reports that everything is normal, everyone applauds.

A series of tests from takeoff to landing and then in the air proved the initial success of the fly-by-wire system.

A series of tests will be conducted in the future, but as long as it can take off and land successfully, it is considered a basic success.

Later, the test pilot wrote in his memoirs: He had never thought that flying an airplane could be so easy, so easy that it made him feel unrealistic.

This is the advantage of the fly-by-wire control system. It has fast response speed and convenient operation, which reduces a lot of operations for the pilot.

After the aircraft landed, it underwent a comprehensive preliminary inspection. An hour later, the aircraft began to repeat the last test.

This time the aircraft still flew according to the scheduled flight test plan.

"I didn't expect to encounter something like this today. Fortunately, the security in our factory treats everyone equally."

There was no celebration party or anything like that today. After the test flight, these leaders said hello and left because today's matters had to be dealt with.

Sun Aiguo also cursed: "These dogs still think that their lives are not good enough. They should be thrown to the northwest."

"I eat the country's food, live the country's food, and even drive the country's car. I still despise my current life."

"People are so weak that if there is no security in our factory today, we don't know how much things will be leaked!"

"Forget about the plane, the key is the relevant technical personnel, especially you, Gong Liu."

Liu Hai looked at the angry factory director and said, "I personally believe that no one can evade safety inspections, not even the leader."

"That's for sure. I will mention this at the next meeting. Anyone who refuses to let the security check go out as soon as possible and don't come!"

"Bald eagles, these bastards!"

Liu Hai nodded: "I'm afraid there will be a lot of people like this in the future. Now that both big countries have mushroom eggs, the possibility of direct conflict is 0."

Then Liu Hai touched his chin and said: "Actually, I personally think that a property registration system can be established to allow everyone to register their property regularly."

Sun Aiguo nodded when he heard this: "Your method is good. I will personally promote this matter. Although it will offend a group of people, I will retire in two years anyway."

"Just taking this opportunity, others dare not speak now. I will scold anyone who speaks." Sun Aiguo said again.

Liu Hai also had this consideration. If it weren't for the security in the factory, who knows how much trouble would have happened this time.

Now it is easy for Sun Aiguo to use this incident to push forward his proposal.

After all, Sun Aiguo's influence is not small, and he has supported many technical and equipment personnel from brother units.

There is also a subordinate with great influence like Liu Hai under his command.

Liu Hai got off the car, and Sun Aiguo went directly to the superior department. Today's incident had a great impact.

The small jet aircraft will undergo three months of air flight tests before it can be finalized.

The next day on Sunday, Liu Hai did not go to work. Today, Liu Hai accompanied his junior sister and two children, and his junior wife went to visit her own museum.

To the east of Panjiayuan, there are several large museums. Few people know that these museums are private properties.

Kyoto Porcelain Museum! Liu Hai and his family first came to the Porcelain Museum. Looking at the name, they thought it was a work unit. In fact, it was a completely private property.

All the porcelain on display are inside bulletproof glass covers. There are pieces of precious porcelain in a row of bulletproof glass display cabinets against the wall.

Yan'er and Xiaofeng were walking in front of Liu Hai.

Tickets are 20 cents per person, children, students, soldiers, disabled people are free of charge.

But even so, there are many people visiting.

"There are so many people!" Junior sister never thought that visiting a museum would be like visiting a shopping mall, almost in groups.

"How about we go to other museums?" Liu Hai asked as he looked at the security personnel following him to separate the others.

"What museum should we go to?"

"Let's go to the Miscellaneous Museum. There are some special antiques there." Liu Hai was talking about the Yongle Sword. This was the antique that the dealers got in exchange for Liu Hai's information fee from the gold treasures they searched for at the Third Master's house.

The Ming Dynasty is definitely a special era in the history of our country. It is said that no one excavated Lao Zhu’s tomb, even under the guise of archeology. No one dared to dig it. Of course, Lao Zhu’s neighbors were also very awesome.

"I heard that there are ancient Dunhuang scrolls. Where is this?" Junior Sister asked curiously, looking at the beautiful porcelain behind the bulletproof glass.

"This seems to be in the Painting and Calligraphy Museum!" As soon as Liu Hai finished speaking, the person in charge of security said something in Liu Hai's ear.

"It's better not to go to other museums. It is said that other museums are full and no one is allowed to enter for the time being. How many people come in as many people go out."

"Why are there so many?"

"I don't know either!" Liu Hai couldn't understand why there were so many people in the museum.

What Liu Hai didn't know was that these museums had been open to acquiring various old objects in recent years, and then these people's rumors were quite outrageous. Some said that tens of millions were spent on acquiring these old objects, and some said that hundreds of millions were spent.

So after these museums opened, the rumors became more and more outrageous.

Mainly because at the beginning of the collection of old items, there were too many people coming here to sell old items, and there were hundreds of people queuing up anytime and anywhere.

From time to time, it is said that some people have sold porcelain bottles for hundreds or even thousands, and some people say that copperware has been sold for five or six thousand.

Some even say that some ancient books have been sold for tens of thousands.

In addition, when people come to sell old items, when people ask how much they sold for, they all mysteriously say that they didn’t sell for much.

There are also some tomb robbers who sell the things they dug up, and then were sentenced to more than ten years in prison.

Anyway, as there were more rumors, the people became more curious, and it became one of the chats after dinner. Of course, these chats became more and more outrageous, and some of them said that they were people I knew, my relatives, and so on.

So after the museum opened, locals like Kyoto were curious about how many good things it had collected over the years, and I wanted to take a look.

There are also some people who sell old objects to museums, so they bring their colleagues and friends to show off and see if this is what I have sold.

And because the acquisition of old objects is open here, a large number of people have made a fortune by flipping objects.

Some people even sold their chicken food bowls and bought their son a new motorcycle.

Others sold the rice jars in their homes and bought a new set of furniture for their son and wife.

It doesn't matter at first glance. These old objects actually have relatively detailed information. For example, what is the age of this porcelain? What type of porcelain does it belong to? Where is the kiln mouth?
Because a large number of people in Kyoto like some old objects, many people come to see the real ones with a learning attitude.

In addition, there are reports in newspapers about which museum has some precious old objects, such as the Yongle Sword.

There are also Dunhuang ancient biographies and Dunhuang murals that were snatched away by others before.

Many people are curious about these things. It seems that they were originally in the British Museum. Why did they come back? Is it a fake?

All kinds of blessings led to the crowds here on Sunday.

Even in ordinary times, there is a lot of traffic, because this is not a single museum, but several museums, and it has become a landmark building invisibly.

After walking around in a circle, Liu Hai came out with his family, and then went to the Five-Star Plaza for a stroll, which was also crowded.

Especially the Tropical Botanical Garden in Five Star Plaza. In winter, people in Kyoto who want to see some greenery have to come here.

"It's okay here at Five Star Plaza. I've been eating fried noodles here for many years and the taste hasn't changed!" Zhu Haiyang said on the way back.

"That's right, last time I wanted to eat noodles from the restaurant at the school entrance, but the taste changed after I ate them." The teacher's wife nodded.

"I've eaten it too, mainly because there's something wrong with his sauce." Zhu Haiyang also nodded.

"Are you going to watch a movie this afternoon?" Liu Hai asked looking at the junior sister sitting in the passenger seat.

"You guys go ahead, I'm not going!" The junior sister looked like she wanted to go back to rest with her big belly.

"Mom, I want to watch a movie, I want to see Panda, I want to see Transformers." Yan'er and Xiaofeng shouted from behind.

"Then, Junior Sister and Teacher, you go to the movies, and I will accompany Junior Sister home." Movies like Transformers, Kung Fu Panda, etc. have already been screened in China.

"That's fine!" The master's wife nodded.
