Chapter 707 Safety Story (Second Update)

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

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

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

Liu Hai smiled and said, "We are so close. It took 10 years to get along with each other, and 100 years to sleep on the same pillow. In fact, I never thought I would be able to have this day."

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

"In fact, it's not just me, but everyone at that time, including everyone in our village, couldn't think of living like this today."

"You have made a great contribution to this. You have made a very important contribution to the development of industrialization in our country." The junior sister nodded when she heard this.

"That's true, but without the country providing a stable environment and without the efforts of other workers, my invention alone would be useless."

"History has never lacked geniuses or people with ideas. It's not heroes who make the times, but the times that make heroes. If it were 50 years ago, even if I had any ability, I would have been forced to go with the flow in such a turbulent environment." Liu Hai has seen a lot of things in his two lives.

Some people think they are extremely awesome and that they are leading the times.

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

"Brother, do you know what I admire most about you? It's that you take all personal honors too lightly. If someone else had achieved the same thing as you, I don't know how proud they would be."

"If you were with other people in the factory, they wouldn't know that you were any different."

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

The brothers and sisters whispered a lot more.

The next day, Liu Hai got up early and came to the factory, because today was the first day of the flight test of the small jet airliner.

The reason why the ground test took so long is mainly because of the fly-by-wire flight control system.

We were completely blank in this area, and Liu Hai laid a foundation this time.

So we have to test repeatedly to ensure the safe operation of the fly-by-wire flight control system.

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

Because it is experimental, everything is moving forward by trial and error, although Liu Hai has already provided a foundation.

However, the fly-by-wire flight control of different models of aircraft is very different.

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

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

In order to further increase the security work of the confidentiality department, all employees of the confidentiality workshop, including all the responsible persons, take a minibus.

Of course, security checks in and out are inevitable.

"Engineer Liu!"

"Engineer Liu!" These leaders greeted Liu Hai when they saw him.

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

Liu Hai was quick, of course. He knew where to place what sensors, where to place computer systems, and what calculation models were needed.

What about the flight attitude control system?

Other departments had to slowly explore how many sensors were needed on the wings, and they could only test this step by step.

There was also the identification of the electrical signal control system for the motor that controlled the wing. To what extent should the motor run? To what state should the wing be controlled?

All of these required the computer to identify the pilot's operation signal and then transmit it to the control units on the wing.

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

The pilot gave a take-off signal, and all computer systems had to identify what state the various parts of the take-off aircraft should be in?

Then what state should be required for landing? This was all identified by the computer through the fly-by-wire signal and then transmitted to the control unit.

At the same time, the computer also had to identify the current attitude through the sensor, otherwise it would be troublesome if it was accidentally identified incorrectly.

The fly-by-wire flight control system is even more powerful when used in fighter jets, because it can reduce the difficulty of operation for pilots and give pilots more time to think.

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

At the airport, Liu Hai and others got off the car for security check.

It can't be said that a leader will not accept security check, this is impossible.

Liu Hai knew that some project leaders in our country had done something in 2020. It seems that there is also a chief engineer of a certain type of missile? Or even the head of a certain security department?

Sometimes some things can't stand thinking about them. Liu Hai had just passed the security check, but he didn't expect that there would be a commotion behind him.

The security personnel responsible for protecting Liu Hai separated Liu Hai from others at the first time.

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

Even Sun Aiguo quickly followed Liu Hai and ran to the side, but the other leaders who followed him were confused.

"They are all a bunch of trash." Half an hour later, Sun Aiguo cursed.

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

And there was only one cigarette in the cigarette box, the others were full, but the other cigarettes were half-smoked.

The miniature camera was placed at the bottom of the cigarette box.

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

Liu Hai originally thought that he had made a mistake, but then the factory director said the man’s surname: Yu!

Liu Hai remembered that in history, it seemed that this guy only went abroad in the mid-1980s.

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.

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

As a result, less than 20 minutes later, the security department came to report to Sun Aiguo.

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

The security department of Dongfang Heavy Industry is of a very high level, and as for weapons and equipment, I won't talk about them.

It turns out that the test flight field of Dongfang Heavy Industry has long been watched by others.

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

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

And promised that as long as he could take photos this time, whether it was the plane or other staff, each photo would be 500 US dollars, and the minimum was 10,000 US dollars, which means that even if he took a photo, it would be 10,000 US dollars.

So the flight test of the small jet airliner was postponed for two hours

But there was no way not to conduct the test because of the weather, so today was chosen.

This matter did not need Liu Hai to worry about it at all, and even the factory director continued to watch the flight test as if nothing had happened.

The two pilots in the small jet airliner were very nervous, and the test pilots of the main and co-pilot listened attentively to the orders of the test leader.

The main driver used fly-by-wire flight control. Once the fly-by-wire flight control had a problem, the co-pilot would immediately use the hydraulic control system.

Liu Hai was not nervous. If there was a problem with the fly-by-wire flight control, the hydraulic control system would be used immediately.

Liu Hai designed the hydraulic control system to have a higher priority than the fly-by-wire for this test flight.

That is, as long as the hydraulic control system intervenes, the fly-by-wire system will default to giving up any operation.

In terms of flight control, system conflict is absolutely fatal.

Liu Hai knew several air crashes in his life. The pilot wanted to pull the plane up, but the system pushed the plane down.

This is basically a problem of system authority priority.

The same problem also exists in the new energy vehicles behind, where the pilot stepped on the brakes while accelerating.

In fact, a priority can be set. As long as the brakes are pressed, even if the other foot is on the accelerator, the system should default to not continue to accelerate.

As for the wrong accelerator, this can also be prevented, because Liu Hai has a navigation system when crossing. If the vehicle status is detected to be abnormal, the accelerator can be completely relaxed.

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

After all, when Liu Hai is crossing, the throttle is an electronic control signal, not a mechanical control.

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

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

When they heard that the plane had reached the predetermined height and everything was normal, everyone breathed a sigh of relief, which was at least half successful.

Then the plane carried out a series of tests in the air according to the command, such as climbing and turning.

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

When the plane landed completely and the pilot reported that everything was normal, everyone applauded.

From takeoff to landing and then to a series of tests in the air, it proved that the fly-by-wire system was initially successful.

A series of tests will be carried out in the future, but as long as it can take off and land successfully, it is basically successful.

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

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

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

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

"I didn't expect to encounter such a thing today. Fortunately, the security in our factory treats everyone equally."

There was no celebration party today. After the test flight, these leaders said hello and left, because today's matter must be dealt with.

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

"They eat the food of the country, live in the country, and even drive the car of the country, but they still despise their current life."

"People are greedy. If there was no security in our factory today, I don't know how much information would be leaked!"

"The plane is fine, the key is the relevant technical personnel, especially you, Mr. Liu."

Liu Hai looked at the angry factory director and said, "I personally think that no one can escape security inspection, even the leaders."

"That's for sure. I will mention this at the next meeting. Whoever does not allow security inspection should get out as soon as possible and don't come!"

"Bald eagles and other bastards!"

Liu Hai nodded: "I am afraid there will be many such people in the future. Now that both major countries have mushroom eggs, the possibility of direct conflict is 0."

Then Liu Hai touched his chin and said, "In fact, 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 promote this matter personally. Although it will offend a group of people, I will retire in less than two years anyway."

"It's just right to take advantage of this opportunity. Others dare not speak now. Whoever speaks up will be scolded." Sun Aiguo said again.

Liu Hai also had this consideration. If it weren't for the security in the factory this time, I don't know how big a thing would happen.

It is still easy for Sun Aiguo to use this incident to launch his proposal.

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

There are also subordinates like Liu Hai who have great influence under him.

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

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

The next day, Sunday, Liu Hai did not go to work. Today, Liu Hai accompanied his junior sister, two children, and his master's wife to visit his 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. Seeing the name, they thought it was a unit, but in fact, it was a completely private property.

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

Yan'er and Xiaofeng walked in front of Liu Hai.

The ticket is 20 cents per person, and children, students, soldiers, and disabled people don't have to pay.

But even so, there are many visitors.

"So many people!" Junior sister never thought that visiting a museum would be like shopping in a mall, almost several people.

"How about we go to other museums?" Liu Hai asked, looking at the security personnel following him and separating the others.

"What museum should we go to?"

"Let's go to the Miscellaneous Museum. There are several special antiques there." Liu Hai was talking about the Yongle Sword, which was the antique that the dealers had exchanged for the information fee they had paid to Liu Hai for the gold treasure they had looted from the Third Master.

The Ming Dynasty was definitely a special era in the history of our country. It is said that no one excavated Zhu's tomb, even under the guise of archaeology. Of course, Zhu's neighbors were also very powerful.

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

"This seems to be in the Calligraphy and Painting Museum!" Liu Hai had just finished speaking when the person in charge of security whispered something in Liu Hai's ear.

"It's better not to go to other museums. It is said that other museums are full of people. People are not allowed to enter for the time being. How many people go out and how many people come in."

"Why are there so many people?"

"I don't know!" Liu Hai didn'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 buying all kinds of old objects in recent years, and then the rumors about these people were quite outrageous. Some people said that they spent tens of millions to buy these old objects, and some people said that they spent hundreds of millions.

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

Mainly because when they first bought old objects, there were too many people coming here to sell old objects, and there were hundreds of people queuing up anytime and anywhere.

It was also reported from time to time that some people sold porcelain bottles for hundreds or thousands, and some people said that bronzes sold for five or six thousand.

There were even some people who said that some ancient books sold for tens of thousands.

In addition, when people who came to sell old objects were asked how much they sold for, they all said mysteriously that they didn't sell for much.

There were also some tomb robbers who dug things up and sold them, and then they 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 gossips after dinner. Of course, these gossips became more and more outrageous, and there were also some people who said that I knew people, my relatives, etc.

So after the museum opened, the locals in Kyoto were curious about how many good things they had collected over the years, and I wanted to see.

Some people who sold old items to museums would bring their colleagues and friends to show off and say, "This is what I sold."

And because the old items are open to purchase here, a large number of people who have become rich by reselling items have also emerged.

Some people even sold their chicken feeders at home and bought a new motorcycle for their son.

Some people sold their rice jars at home and bought a new set of furniture for their son and daughter-in-law.

It turned out that these old items actually have relatively detailed information, such as what era this porcelain is? What kind of porcelain is it? Where is the kiln?

Because a large number of people in Kyoto like some old items, many people come to see the real thing with a learning attitude.

In addition, newspapers are reporting on which museum has precious old items, such as the Yongle Sword.

There are also Dunhuang ancient legends and Dunhuang murals that were stolen by others before.

Many people are curious about these things. It seems that they were originally in the British Museum. How did they come back? Are they fakes?

All kinds of blessings have led to the crowds here on Sundays.

Even on normal days, there are still a lot of people, because this is not a single museum, but several museums, which have become landmark buildings invisibly.

After a round, Liu Hai went out with his family and went to the Five Star Plaza to visit. This place is also crowded.

Especially the tropical botanical garden in the Five Star Plaza. In winter, Kyoto people can only come here to see some green.

"The Five Star Plaza is okay. I have eaten the noodles with soybean sauce for many years, and the taste has not changed!" Zhu Haiyang said on the way back.

"That's right, last time I wanted to eat the noodles with soybean sauce at the restaurant near the school gate, but the taste changed after I ate it." The master's wife nodded.

"I have eaten it too. The main problem is that his sauce is problematic." Zhu Haiyang also nodded.

"Are you going to the movies in the afternoon?" Liu Hai asked the junior sister sitting in the co-pilot.

"You guys go, I'm not going!" The junior sister was pregnant and seemed to want to go back to rest.

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

"Then Master's wife and teacher, you guys go to the movies, I'll go home with Junior Sister." Movies such as Transformers and Kung Fu Panda have been shown in China.

"Okay!" Master's wife nodded.
