Siheyuan: Grassroots Counterattack

The next morning, everyone gathered in the workshop. At Li Tianyi's command, everyone started to get busy. They assembled the various parts of the engine according to the drawings, and then put them together.

Li Tianyi did not take any action, but if there was any problem, he would solve it in time.

The biggest problem is the inconsistency of sizes. The measuring tools used in factories across the country are not standardized, so under the same scale, parts produced in different factories will have errors. Although the errors are not large, there will still be gaps when they are assembled together, or they cannot be assembled together at all.

Before sending the team members down to make parts, Li Tianyi had thought of this problem, so he allocated three sets of parts. Even so, the engine was almost not assembled.

After a day of modifications and reassembly, the engine was finally assembled before leaving get off work in the afternoon.

Everyone in the workshop breathed a sigh of relief. Li Tianyi asked Xiao Zhou to go home and tell Xiao Xue that he would be working overtime tonight and would not be going home.

Then Li Tianyi announced that they would work overtime today and test the engine tonight. No one objected, after all, the engine had been assembled, and if they didn't test it, they might not be able to sleep tonight.

After dinner, everyone came to the workshop again. Li Tianyi and the two team leaders checked the machines one last time. After finding that everything was normal, Li Tianyi announced the start of the test.

First, we do component testing, which tests the various parts of the engine, such as turbine blades, compressor blades, combustion chambers, etc., and conducts separate performance tests.

Here, more emphasis is placed on the engine's vibration test and thermal cycle test, which are the guarantee for ensuring the normal operation of the engine under extreme conditions.

In fact, it is simple to say here, but it is very troublesome to actually do it. Each test has to be done several times, and there are special recorders to record the data. These data will finally be written into the report and submitted to the superiors.

Li Tianyi and his team spent an entire night on this first test. After the first test was completed, the data was normal. Li Tianyi announced that they would take a break in the morning and continue testing in the afternoon.

Although everyone was excited, they were also very tired after not sleeping all night, so after breakfast they all went back to the dormitory to rest.

Li Tianyi doesn't have a dormitory here, so he slept on the sofa in his office for the whole morning. When he got up at noon, although he felt uncomfortable all over and his neck was very stiff, he still had to get up to eat because he had other things to deal with in the afternoon.

After lunch, everyone gathered in the workshop again. Li Tianyi saw that everyone was in good spirits, but he still said some words of encouragement to everyone. Then he used a crane to move the engine to the test bench. This time, a bench test was carried out.

The engine is installed on a special test bench to simulate various flight conditions and test different speeds, temperatures, pressures, and fuel supplies. Under different conditions, the changes in engine data are observed, and then the engine's thrust, power, fuel consumption rate, and key emission parameters are obtained.

After several hours of monitoring and observing the engine's operating status through data, everyone was extremely nervous during these hours, for fear of overlooking any small abnormality. Li Tianyi focused on checking whether the engine had abnormal vibrations, whether there was noise after the operation process, or whether the engine had run for too long and whether it was overheated.

These problems are fatal. If they do not monitor these problems, but the engine has problems after the plane is in the air, the life of a pilot may come to an end, so Li Tianyi and his colleagues dare not relax at all.

The experiment lasted until evening again. When it was finished, it was already late at night. Li Tianyi and other recorders sorted out the data and looked at the data. No abnormalities were found, so they asked everyone to rest and continue with the next experiment tomorrow morning.

Everyone was very tired after the past two days, so they didn't say anything and dragged their tired bodies towards the dormitory.

Li Tianyi also asked Xiao Zhou and Xiao Zhao to go home. He also needed to have a good rest, otherwise his body would not be able to take it.

Cars were driving in the military area at night, and from time to time there would be patrolling soldiers and pickets. Along the way, Xiao Zhao's car was not driving fast. Whenever he met someone, he would be stopped and would only be allowed to pass after checking their documents.

We were stopped several times along the way before finally arriving at the family compound.

Xiaoxue was resting at this time. Hearing a knock on the door, Xiaoxue put on her clothes and asked who was knocking. Li Tianyi's voice came from outside the door, so Xiaoxue went to open the door.

Li Tianyi asked Xiao Zhou and Xiao Zhao to go back and rest and come back tomorrow morning, and then he went back to the house with Xiao Xue.

"Brother Tian, ​​are you hungry?" Xiaoxue looked at Li Tianyi's sloppy appearance and was worried that he had not eaten dinner, so she asked.

Li Tianyi felt it and found that he was indeed a little hungry. "A little hungry."

"Then I'll cook you a bowl of noodles and boil some water for you. You look so dirty, go wash it later."

Li Tianyi giggled foolishly. Xiaoxue rolled her eyes at him and went into the kitchen.

Li Tianyi went into the room and found some clean clothes, then kissed his son who was sleeping on the bed.

As soon as he came out of the house, Xiaoxue asked him to take a shower first and then cook the noodles after he finished.

Li Tianyi obediently went to wash up. When he finished his shower, Xiaoxue had already brought a bowl of hot noodles to the table in the living room. The noodles were sprinkled with chopped green onions and an egg.

Li Tianyi was really hungry at this time, so he asked Xiaoxue if she wanted to eat. After Xiaoxue refused, Li Tianyi started to eat noodles in big mouthfuls. In less than ten minutes, he had finished a bowl of noodles.

Li Tianyi breathed a sigh of relief, looked at the time and found that it was already past 12 o'clock, so he hurriedly brushed his teeth and washed his face, then hugged Xiaoxue and went back to the house to sleep.

The next morning, Li Tianyi was awakened by feeling suffocated. As soon as he opened his eyes, he saw his little son smiling slyly above his head, pinching his nose with his little hand. Li Tianyi stretched out his hand and scooped Doudou up. Doudou laughed. Li Tianyi put Doudou in his quilt and covered him with the quilt. The two of them made a noise in the quilt.

An An, who had already gotten up, sighed helplessly, whispered something childish, and then went out of the house to find her mother.

After a while, Xiaoxue walked into the room and saw that the father and son had not yet gotten up. She immediately turned into a lion and shouted at Li Tianyi to get up.

Li Tianyi and Doudou looked at each other and hurriedly put on their clothes, while An An watched and smiled from the side, without any guilt at all for telling the truth.

After breakfast, Xiao Zhou and Xiao Zhao were already waiting outside the gate. Li Tianyi told Xiao Xue that he was busy these two days and might have to work overtime at irregular intervals, so if he didn't come back after mealtime, he would let Xiao Xue and the children eat first.

Xiaoxue said she knew, watched Li Tianyi's car go away, then turned around and started to take care of the two brothers again.
