Accompanied by He Peitian, Li Shan successfully completed all the formalities, including personal identity registration, receiving access documents, etc., and also signed a confidentiality agreement, which were formatted documents, and Li Shan signed them without looking carefully.

After the formalities were completed, Li Shan followed He Peitian to the guest house, and along the way, He Peitian read out to him the precautions for confidentiality as usual, and instructed him to carefully read the confidentiality regulations, which is a normal working procedure, and Li Shan has no objection to this.

Li Shan still lives in the same building where he lived on a business trip last time, but this time he lived on the first floor, and last time he lived on the second floor. He clearly remembered that the last time he came, one night, just in time for a thunderstorm, when the lightning split a willow tree behind the building, Li Shan also went to take a look, and found that there was no trace of the past, and a row of small trees were planted behind the building, which were not tall, and they knew that they had just been planted at a glance.

Li Shan felt a little confused about what task he wanted to perform on this business trip, and he didn't explain it clearly, but vaguely said that this mission was related to Flying Tiger, which seemed very mysterious.

In addition to Li Shan, the people sent by Hongqi Factory to serve at the 727 base this time also have other personnel who have arrived here in the early stage, and Li Shan needs to report to this team and accept relevant work tasks.

Li Shan first got in touch with Zhao Xiaolin of the process technology center of the factory who was responsible for the liaison here, and he told Li Shan that the rest of the service team of the Hongqi factory will arrive here one after another today, and at 7 o'clock in the evening, the service team will organize a meeting of these people to arrange the work of the next few days.

In the evening, Li Shan came to the door of room 2105, and when he saw that the door was closed, he knocked on the door and heard someone in the door say, "Please come in." He pushed the door open and walked in.

This room is a suite, much larger than the standard room where Li Shan lives, the inner room is a place for guests to rest, and the outer room is a reception room, which is relatively spacious and can be used to entertain guests or have a small meeting or something.

At this time, there were already four or five people sitting in the reception room, and a middle-aged man with a little bow on his head in the middle was obviously the core of these people, and the others were talking around him, and when they saw someone coming in, they stopped talking and turned their eyes on Li Shan.

Before Li Shan could speak, the middle-aged man stood up with a smile and said, "You are Xiao Li, please come in." After speaking, he took the initiative to stretch out his hand to Li Shan.

Li Shan, a middle-aged man, knew that he often saw photos of this person in the factory broadcasts and newspapers, and knew that he was Deng Lixin, deputy general manager of Hongqi Factory, the leader of the service team sent to the 727 base by the factory, and the top leader of Hongqi Factory here.

Li Shan didn't dare to slack off, hurriedly took a few steps forward and held this person's hand with both hands, and said in his mouth: "Mr. Deng, hello, I am Li Shan." "When I shook hands with him, I felt that the other party's handshake was quite strong.

"Hehe, Li Shan is so young, it seems that we have another new force, with your joining, our strength is more substantial, Xiao Li, there are several other comrades in the factory, they are also the elite soldiers sent by our factory, let me introduce to you, this is Wang Zizhong of the design institute, this is Zhao Xiaolin of the process technology center, this is..."

Li Shan secretly calculated, plus there are a total of six people in his team, it seems that this lineup is still relatively large.

"Now that everyone is here, let's have a short meeting. The comrades who arrived early were already clear about the purpose of coming here, but the later comrades may not be very clear. This is due to the confidentiality of the work, did not reveal to you in advance, now that everyone is here, then I will now tell you the bottom, our mission this time is to escort the first test flight of the 'Flying Tiger'. As soon as Mr. Deng's words came out, they immediately caused a burst of remarks from everyone.

As one of the few fourth-generation aircraft in the world today, the Flying Tiger has long attracted the attention of the outside world, and the aircraft was successfully ignited last year, and it has only been a year since the start of test flights, and the process is fast enough.

This is the first test flight of the Flying Tiger, and everyone knows what it means, and it is an honor and a responsibility for everyone to be able to witness this historical moment in their lives.

Everyone's reaction seemed to be expected by Mr. Deng, he kept looking at everyone with a smile on his face, and only then did he continue to speak when everyone had digested the news. "A week later, the Flying Tiger is about to make its first flight, what does the Flying Tiger mean to the Huafu Air Force, needless to say, everyone is very clear, at that time, there are not only senior leaders of the country and the military who are watching, but also some media from all walks of life watching around, so this first flight must be foolproof, the task assigned to us by the command is not to allow a little problem with the engine, and I will give you a division of labor in the past two days, Wang Gong, you continue to be responsible for reviewing the technical status of the Huashan engine, Zhao Gong, you are responsible for reviewing the production process and production conditions....”

Next, in accordance with the requirements of the Flying Tiger Command, Mr. Deng made a detailed arrangement of the work tasks in the past few days, and Li Shan's main task this time was to cooperate with the airport to conduct the final inspection of the external equipment of the Huashan engine, and at the same time, to conduct a visual inspection of the visible parts of the engine.

After the division of labor was completed, Mr. Deng said: "Today's meeting is here, everyone go back and rest early, and raise your spirit to meet tomorrow's work." After saying this, everyone got up and prepared to leave.

When Li Shan also got up to leave, Mr. Deng patted him on the shoulder and said: "Xiao Li, this time, President Qi of the Flying Tiger Command specially named you to participate in the service support work of this test flight, which shows that the above attaches great importance to you, and I hope you will not live up to the trust of the leaders and comrades, and win glory for our Red Flag Factory and our aviation people." ”

Li Shan also had a burst of enthusiasm when he heard this, knowing that it was time to express his position, he learned from the heroes in the movie and said: "Please rest assured that the organization will complete the task!"

The next day, Li Shan went to the scene of the Flying Tiger with other personnel in the factory. In front of the hangar, there is also a sentry guard, and the sentry with rifles checks them more strictly, not only carefully verifying the identity of each person, but also opening the equipment they carry with them and checking them one by one, and after checking, putting them on top of the X-ray machine.

After passing the inspection, Li Shan and the others were able to enter the hangar.

As soon as I entered the hangar, I saw that there was only a yellow-painted aircraft in the hangar of Nuoda, surrounded by all kinds of instruments and equipment, and many people in work clothes were busy around this aircraft, which was the fourth-generation aircraft flying tiger that had been rumored to be in the outside world for a long time.

At this time, an old man with gray hair and gray long overalls in the crowd greeted him, he shook hands with Mr. Deng and said, "Comrades have to work hard for a few more days." "This person is Qi Yulin, the deputy commander of the Flying Tiger model.

Mr. Deng said: "Don't worry, Mr. Qi, we will do our best." ”

Mr. Qi looked at Li Shan at the end of the team again, and said with a smile: "Xiao Li, hello." ”

Li Shan stepped forward quickly and said, "Hello Mr. Qi." He knew that he could come here this time, it was all a sentence from Mr. Qi, and it was precisely because of his outstanding performance on the last business trip that Mr. Qi was impressed, so he asked him to come by name.

"Good job, boy. Mr. Qi patted Li Shan's shoulder cordially and said.

The feeling of being valued is different, Li Shan has not felt this feeling since he was a child, so he showed some sincerity and fear.

After a few simple polite words, Li Shan and the others threw themselves into the intense work. ”

The shell of the aircraft has been fully opened, and the engine compartment inside can be seen, but this also only partially reveals the outline of the engine. Li Shan needed to remove a thermocouple on the engine, which was a device used to monitor the temperature of the engine when it was running. There are several such devices on the engine that monitor the temperature at various locations while the engine is running.

The place that Li Shan disassembled is located in the core area of the engine, which is the worst place in the engine working environment, so this is also the key area of Li Shan's inspection, and the inspection aspect is to visually check the status of the parts through the hole finder.

After taking out this thermocouple, revealing a hole inside, Li Shan carefully extended the hole detector into the inside of the engine, here is mainly the engine compressor rotor and turbine parts, the rotor and turbine have as many as hundreds of blades, Li Shan not only has to check the blades one by one, but also to check the cracks, wear, burns, corrosion and other defects of other internal components, and report to the technicians for evaluation in time if problems are found.

The probe reaches into the engine and uses the principle of optical imaging to transmit an image of its interior, which is finally displayed on a display. Li Shan uses visual observation to detect and evaluate the internal situation. These images are all black and white images, and it is very difficult to look at them, and Li Shan has been watching them for more than two hours, and he is only dazzled.

"Xiao Li, you take a rest first, I'll take a look. At this time, the craftsman Zhao Xiaolin came up and proposed to change him, and Li Shan did not shirk, so he gave him the position of observation.

The color of those leaves is ordinary black and white, and because it has been seen for a long time, there is some color difference in Li Shan's view of the outside world. He sat on the ground and got used to it for a while before his sight returned.

He picked up a bottle of mineral water that was placed on the ground, unscrewed the cap and took a few sips, his eyes looking around.

At this moment, he sat under the fuselage of the Flying Tiger, looked up at the plane above, and he had also seen reports about the plane on the Internet, all of which were taken by some military fans through long-distance cameras.

Due to the long shooting distance, the image is not very clear, but even this has attracted onlookers from military fans at home and abroad.

If you take a photo with Feihu here and put it on the Internet, I believe it will definitely win a lot of clicks.

But he also knows that this is absolutely impossible, this kind of photo is taken by the outside world is their ability, but it is absolutely not allowed internally, this kind of behavior is a kind of leakage, at least get out of the place, or go to military court, so it can only be a sexual obscenity.
