Wu Zhishi slowly left the ground and flew into the air in everyone's eyes. Everyone's eyes were chasing Wu Zhishi in the air tightly.

Wu Zhishi slowly rose. After rising to a certain height, he adjusted a brief hover and then began to climb up at a large elevation angle, flying higher and higher. After reaching a certain height, he began to carry out a series of work in the air according to the test flight subject.

"Wow, this action is so beautiful!"

"Look, that's flying backwards!"

"Ou Ye, it's so wonderful!"

On the ground, everyone watched Wu Zhishi start a series of movements, which were thrilling and dazzling. Many soldiers cheered and opened their eyes.

On the helicopter, Feng Zhengqi smiled slightly and thought to himself that it was just a side dish, and it was even more exciting!

As soon as the operating rod was pushed, the helicopter rushed downwards at a high angle, like an arrow from a string. When everyone saw that their hearts almost jumped out, they didn't look like a helicopter, but they were a bit like a fighter. Wu Zhishi rushed down at a height of hundreds of meters in everyone's eyes. When it was very close to the ground, it changed to a high elevation angle to reach a certain height, which was another series of wonderful actions.

It was exciting and exciting, everyone said it was enjoyable.

Everyone was about to cheer, and shouted happily. The eleven Wu Zhi in the air flew backwards. Seeing that this was the case, there would be more exciting movements. Suddenly, everyone swallowed the cheers back, and their hearts instantly hung up and raised their throats.

The drama is about to begin!

Sure enough, this Wu Zhishi in the sky began a series of dazzling and exciting actions that everyone had never seen before, and was almost amazed.

"What's the action!"

"Yes! Why have I never seen it before?"

"My God. Armed helicopters can still play such actions, it's awesome!"

"Excellent, today is an eye-opener!"

“…”

Seeing such exciting and exciting movements, everyone cheered and felt refreshed. In the sky, Feng Zhengqi was also impressed. This turboshaft engine is so powerful. If the domestic turboshaft C engine is equipped with 10-mount domestically produced turboshaft C engine, don’t even think about completing such a difficult action.

After a series of exciting things, Wu Zhishi slowly landed at the designated location and stopped steadily. After Feng Zheng's plane, he walked over quickly.

Stand at attention and salute. Feng Zhengqi said loudly: "Captain, follow the test flight subject and complete the test flight successfully. Please instruct!"

"After a moment!"

After saying that, the commander of the Lu Airlines smiled, "You kid, you have good skills and such actions. I have seen you play so beautifully today."

Feng Zhengqi grinned: "Captain, the main reason is that the engine performance is too excellent and full of power, otherwise, how could it be so smooth?"

Soon, Feng Zhengqi was surrounded by soldiers, and everyone asked this and that. Feng Zhengqi felt happy and thought to himself, Tianfeng Technology Company, you are really amazing, the turboshaft D engine. It's really excellent.

A few days later, Feng Zhengqi's beautiful and thrilling action was introduced to the military newspaper, and even a military figure learned about it. A military reporter interviewed Feng Zhengqi. Feng Zhengqi was happily talking about how excellent and amazing the turboshaft D engine was.

...

Tianfeng Technology Company.

As time gradually enters the cooler autumn, the 2,000-hour life verification test drive is gradually coming to an end. After several months of test drive, the engine on the test drive table, which is undergoing test drive, has accumulated a total of 2,000 hours.

In the test run monitoring and control room, Li Tianfeng stood there, through the huge soundproof glass, he clearly saw the working engine on the test run. Next to Li Tianfeng, Qiu Wen'an, Sun Xiaoping, Zeng Qinghai and others were slightly excited.

2000-hour life test drive!

Thinking about the test run for several months, everyone became even more excited. It was obvious that the test run was about to be completed immediately, and the engine that was working was very normal.

The test run commander took a look at the control instruments and then took a look at Li Tianfeng. Li Tianfeng clicked a point and issued an order to stop the test run himself.

When these test runners saw Li Tianfeng's gesture, they knew that the 2,000-hour life test run had been completed. Everyone looked at each other and felt happy. One of the test runners took a deep breath and pressed the parking button.

The engine working on the test drive bench gradually stopped until it was completely stopped. As the engine stopped working, the entire test drive monitoring and control room was quiet, and everyone looked at Li Tianfeng one after another.

From everyone's eyes, we can see that everyone's mood is very excited at this moment. It is so exciting and amazing that it is to pass the 2,000-hour test drive successfully.

Li Tianfeng said loudly: "Now I announce that the 2000-hour life test run of the turboshaft D engine was successfully completed!!!"

As soon as Li Tianfeng spoke, everyone immediately cheered, expressing the joy and excitement in their hearts to the fullest!

"Oh! We succeeded!"

"That's great, we successfully completed the 2000-hour life test drive!"

"So happy!"

“…”

The entire control and monitoring room instantly became a sea of ​​joy, especially the test runners, who even stood up and hugged each other tightly.

In everyone's mind, more than a hundred days and nights of efforts appeared, and at this moment, they finally received a generous reward. There was a test driver, and his eyes were even moist, which was tears of joy and joy.

Qiu Wen'an, Sun Xiaoping, Zeng Qinghai and others all looked at each other, their eyes full of excitement. Although everyone, as the backbone of Tianfeng Technology, did not show it, the joy in their eyes was still visible.

The same is true for Li Tianfeng. He felt comfortable and successfully passed the 2,000-hour life test drive. This not only broke the record of the first life test drive of a new aircraft engine in China, but also left a brilliant mark in the development history of Tianfeng Technology.

Now, although the engine has not been decomposed and the condition of the engine parts has not been checked, when the car was stopped just now, the engine data was completely normal and the engine was in normal working conditions, which means that the 2,000-hour life test run was successfully completed.

After 2000 hours of test run, the engine can still work completely normally, which means that the service life of the engine must be at least greater than 2000 hours.

Before the test run, Li Tianfeng accurately estimated that the first turnover life of his engine would be at least greater than 2,000 hours, or even greater than 3,000 hours. Now, through the verification test run, it has been verified that Li Tianfeng's estimate is accurate.

The new aircraft engine is assembled and is tested and released from the factory. It is used in the field until the first overhaul is required. From the factory to the first overhaul, how many hours can the engine be used in total? This is the first life span.

After passing the 2000-hour life test run, the first turnover life of the turboshaft D engine can be positioned at least 2,000 hours. As for whether it can be positioned at 3,000 hours in the future, it can be passed the 3,000-hour life test run.

2000 hours!

What an amazing achievement!

No wonder everyone is so happy, so excited, jumping and cheering, and the entire monitoring and control room is completely filled with joy.

Outside, there were crackling sounds of firecrackers. The director of the test workshop, with several employees, was setting off firecrackers outside the gate of the test workshop factory, almost pushing the warm atmosphere. The employees of the entire test workshop were full of joy!

The good news of successfully completing the 2,000-hour life test drive spread throughout Tianfeng Technology Company not long afterwards. After hearing such good news, all the employees were filled with joy and full of joy and pride.

The next day, the Songzhou Daily even reported on the front page, warmly congratulating Tianfeng Technology Company on its successful completion of the 2,000-hour life test run of the turboshaft D engine.

Such good news not only spread throughout Tianfeng Technology Company, but also to e Factory and to Beijing.

Li Tianfeng received congratulations one by one. Li Tianfeng was in a good mood, and Zhang Haiping also called as soon as possible.

After receiving a call from Zhang Haiping, Li Tianfeng said: "Director Zhang, you are about to report to you."

Zhang Haiping interrupted Li Tianfeng and said happily: "Tianfeng, I already know. Congratulations to you, it is really exciting to pass the 2,000-hour lifespan test drive."

Zhang Haiping knows the value of the 2,000-hour life test run, which not only sets a domestic record, but also represents the excellent performance of the turboshaft D engine, which is gratifying!

Li Tianfeng smiled happily and said, "Director Zhang, next, we plan to conduct a 3,000-hour life test drive. If it passes smoothly, it will be really exciting!"

"What, it really needs to be tested for a 3,000-hour life. This is so exciting. If our turboshaft D engine passes the 3,000-hour life test, then this engine will definitely be among the world's well-known turboshaft engines."

Li Tianfeng clicked a little and chatted with Zhang Haiping for a few minutes, and even talked about airworthiness evidence collection. The work of airworthiness evidence collection on turbo shaft d was started two months ago. Now, the 2,000-hour life test drive is successfully passed. There should be no resistance to the evidence collection, and there will be results soon.

Within two days of successful completion of the 2000-hour life test run, the engine was transported back to the assembly workshop for decomposition and decomposition to the parts state. Each part will be strictly inspected. According to the inspection situation, it is determined whether it can be increased to conduct a small-hand life test run of 1,000.

2000 hours, and 1000 hours are added to 3000 hours. If the life of 1000 hours is added, the test run will be successfully passed. This means that the first turn life of the turboshaft D engine can reach 3000 hours. To achieve such a first turn life, it is enough to compare with the world-renowned turboshaft engine.
