Time was pressing, and the tall expert, Qi Yulin, the deputy chief engineer of Huashan engine model development, personally went into battle, staring at the data on the LCD screen on an instrument, and directing Li Shan to adjust the lever of the fuel flow regulator on the engine.

"Xiao Li, rotate the No. 1 lever in a clockwise direction, yes, that's it, slow down, okay, stop! You rotate the No. 2 lever counterclockwise, slow down, okay, now you use a feeler gauge to measure the gap between the measuring blocks." ”

Li Shan stuffed the feeler gauge between the measuring blocks, "6.41 centimeters." ”

"Oh, that's 0.5 centimeters short. Mr. Qi frowned, turned to an assistant on the side and said, "Is the expert from the accessory factory supposed to arrive today?"

"Yes, Mr. Qi, they were planes around seven o'clock in the evening, and they should still be on their way now. The assistant replied.

"Well, if they get off the plane, you have to tell them to come here as soon as possible. ”

"Okay, I'll let them know in time. ”

In addition, Mr. Li, who notified the 508 Institute, also rushed here as soon as possible. ”

"Yes!"

After Mr. Qi's work was arranged, he turned to Li Shan and said: "Xiao Li, work hard for you a little more, we can get all the data before they arrive, we can buy more time, and we can directly enter the next step of work as soon as they arrive." ”

Li Shan took the train for nearly three hours, and then rushed to the long-distance bus for nearly two hours, plus the excitement on the first night of the business trip was too much and did not rest well, and he felt very tired at the moment, but seeing that the white-haired Qi Zong was still persevering, he had to fight his spirit. No wonder Liu Changhui and they finished the work and ran faster than a rabbit, it seems that this business trip is not as good as they imagined.

Li Shan sneaked to the pool next to him, put his head under the water tap, unscrewed the valve, and let the cold water soak his head directly in the cold water.

"Young man, take it easy, don't make a mistake. When Mr. Qi was resting, he reversed the rigidity and stubbornness at work, and he was still very kind, he admired Li Shan's sincerity in his work, and he couldn't help but remind.

The topography of Shunan Province is generally similar to a basin, with high temperature and drought in summer, and it is one of the hottest regions in China, while its provincial capital city of Rongcheng is at the top of the top ten furnace lists in the country.

Although it was already evening, it was still unbearably hot, unlike my hometown of Sanqin Province, where the temperature during the day was sometimes frighteningly high in the summer, but at night the temperature would drop somewhat. And here is basically the same temperature during the day and night, and the humidity is relatively high, so it feels like steaming sauna. Although several high-power fans at the scene were desperately spinning, the sweat on Li Shan's body still kept dripping, and the clothes all over his body had already been soaked with sweat, and the soaked clothes had been sticking to his body, and he was very sticky and uncomfortable, and he couldn't wait to go back to the guest house immediately to take a comfortable hot bath, but now was not the time to leave, he was tormented in this environment.

It didn't take long for experts from the 508 Institute to come to the scene, and as soon as they arrived, they immediately threw themselves into the intense work.

Taking advantage of this opportunity, Li Shan can finally have the opportunity to enjoy this famous aircraft at home and abroad up close.

This is the legendary domestic fourth-generation aircraft fighter, the military named it "Flying Tiger", with high-speed, stealth, ultra-long cruise capabilities, it is said that its performance is comparable to the most advanced fourth-generation aircraft in the United States.

In the past, the planes seen on TV and in pictures were streamlined and graceful, which was very much in line with the principles of aerodynamics. And now when I look at it so closely, I see that the fuselage is covered with dense metal rivets, which are far from being as neat and smooth as I imagined.

With the joint efforts of experts from the 508 Institute and the accessories factory that arrived later, the test work finally achieved satisfactory results.

When Li Shan and the others dragged their tired bodies back to the guest house, it was already more than four o'clock in the morning, and after a simple wash, they fell asleep, and they were really tired today.

Maybe it was due to improper diet, or due to the lack of adaptation to the water and soil, Li Shan's stomach was not good, and he vomited and vomited within a few days of coming here, and the doctor told him to rest for a few days, but seeing the tense and busy appearance of the scene, Li Shan was embarrassed to lie down, so he had to grit his teeth and insist.

In order not to affect his work during the day, Li Shan could only insist on working during the day and only went to the medical center at night to get hanging bottles.

Looking at Li Shan's yellow and thin face, who was still insisting on working, Mr. Qi saw it in his eyes, and he was deeply moved.

On this day, Li Shan and the two of them got up early, and after breakfast, they took the shuttle bus to the hangar, because today there was an important project to be carried out - the first ignition test run of the aircraft.

When Li Shan and the others arrived at the hangar, they saw that the plane had been towed out of the hangar and parked on the runway in front of the hangar, surrounded by fire trucks, fuel trucks and many unnamed special vehicles. Countless cables extend out of the plane, and the other end of the cable is connected to various instruments, and the staff is already busy. It seemed that they had been busy all night, as could be seen in their red eyes.

Li Shan saw Mr. Qi at a glance in the crowd, his tall and thin figure was more eye-catching in the crowd, this old man was almost seventy years old, how could he still be so energetic? Li Shan sincerely felt admired.

Mr. Qi was holding a walkie-talkie at the moment, with a serious expression on his face.

He was the commander-in-chief of today's ignition test, and at this time he gave instructions to the walkie-talkie, and all the answers came from the walkie-talkie.

There were a lot of people at the scene today, and there was a temporary row of tables not far away, and there were quite a few people sitting behind the tables, including the major general I saw that day, he was just sitting at the very edge of the table, and obviously, the person sitting in the middle was of a higher rank.

As the time approached, the atmosphere at the scene became more and more solemn, and everyone was quietly waiting for the arrival of the historical moment of the plane ignition.

At this moment, the "Flying Tiger" is quietly parked on the runway, like a tiger crawling there, looking so peaceful. But Li Shan is sure that once it flies, it will be a real tiger with wings, and the whole world will be shaken.

Since the development of the "Flying Tiger" fighter, it has attracted strong attention at home and abroad, and many military fans often set up high-powered binoculars around the test flight base and closely follow every move here.

"I wonder if there are spies among these people?" Li Shan looked at the crowd of people watching the excitement on the hills around the base, and guessed like this.
