In everyone's eyes, Wu Zhi Shi slowly left the ground and flew into the air, everyone's eyes closely chased after the Wu Zhi Shi in the air.

Wu Zhishi slowly ascended, after rising to a certain height, a short hovering adjustment, and then began to climb at a large elevation angle, flying higher and higher, after reaching a certain altitude, according to the test flight subject, began to carry out a series of work in the air.

"Wow, that's a beautiful move!"

"Look, that's an upside-down flight!"

"Ouye, it's so exciting!"

On the ground, everyone watched Wu Zhishi start a series of actions, thrilling and dazzling, and many soldiers cheered one after another, which was an eye-opener.

On the helicopter, Feng Zhengqi smiled slightly, and thought to himself, just now it can only be regarded as an appetizing dish, and more exciting is yet to come!

The operating lever pushed, the helicopter rushed down directly at a large inclination angle, like an arrow from the string, seeing everyone's heart almost jumped out, where is this like a helicopter, but a little like a fighter, Wu Zhishi in everyone's eyes, a large inclination angle rushed down to a height of hundreds of meters, when it was very close to the ground, it was changed to a large elevation angle to pull up, reach a certain height, and it was a series of wonderful actions.

Wonderful and exciting, everyone is addicted.

Everyone was about to cheer, shouting happily, the eleven Wuzhi in the air flew upside down, looking like this, there will be more exciting movements soon, suddenly, everyone swallowed the cheers hard, and a heart instantly hung up, mentioning the throat.

The big drama is about to begin!

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

"What kind of action is this!"

"Yes! How have I never seen it before! ”

"Oh my God. The gunship can still play such a move, Oxfork! ”

"Amazing, it's an eye-opener!"

“……”

Seeing such a wonderful and exciting action, everyone cheered and was happy. In the sky, Feng Zhengqi is not. I am greatly impressed, this turboshaft engine is too powerful, if Wuzhi ten domestic turboshaft C engines, I don't want to be able to complete such a difficult action.

After a series of highlights, Wu Zhishi slowly landed at the designated place, stopped, and walked over quickly after Feng Zhengqi took the plane.

Stand upright and salute. Feng Zhengqi said loudly: "Regiment leader, according to the test flight subject, complete the test flight in order, please instruct!" ”

"Take a break!"

After speaking, the head of the army aviation smiled, "You kid, your skills are good, such an action." Being played so beautifully by you, I can be considered to have seen it today. ”

Feng Zhengqi grinned: "Regiment leader." The main thing is that the engine performance is too good and full of power, otherwise, where is it so smooth. ”

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

A few days later, Feng Zhengqi's beautiful and thrilling action was published in the military newspaper, and even known by a certain military bigwig, and a military reporter conducted an interview with Feng Zhengqi, who was interviewed, from time to time happily said how excellent the turboshaft D engine was, how great it was.

……

Tianfeng Technology Company.

As the time gradually enters the cool autumn, the 2000-hour life verification test is gradually coming to an end, after several months of testing, the engine on the test bench has accumulated 2000 hours of work.

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

2000 hours of life test!

Thinking about this several months of test running, everyone's hearts are even more excited, seeing that the test is about to be completed immediately, and the engine that is working is very normal.

The test commander took a look at the control instruments, and then looked at Li Tianfeng, Li Tianfeng nodded a little and personally issued the order to stop the test run.

These test drivers saw Li Tianfeng's gesture and knew that the 2000-hour life test had been completed, everyone looked at each other, and their hearts were happy, and one of the test drivers took a deep breath and then pressed the stop button.

The engine that was working on the test bench gradually stopped, until it finally stopped completely, and as the engine stopped working, the entire test monitoring and control room was quiet, and everyone looked at Li Tianfeng.

It can be seen from everyone's eyes that everyone's mood at the moment is very excited, and how exciting and amazing it is to test it for 2000 hours.

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

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

"Oh also! We did it! ”

"Great, we completed the 2000-hour life test!"

"I'm so happy!"

“……”

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

In everyone's mind, this more than 100 days and nights of dedication came to mind, and at this moment, finally got a rich reward, there was a test driver, and even his eyes were moist, which was tears of joy and joy.

Qiu Wen'an, Sun Xiaoping, Zeng Qinghai and others all looked at each other, their eyes were full of excitement, as the backbone of Tianfeng Technology, although they did not come out, the joy in their eyes was still clear.

Li Tianfeng is the same, his heart is comfortable, and he has a 2000-hour life test, which not only breaks the record of the first life test of a new domestic aero engine, but also leaves a strong mark in the development history of Tianfeng Technology Company.

Now, although the engine has not been disassembled, and the condition of the engine parts has not been checked, but when the engine was stopped just now, the engine was completely normal, and the engine was in normal working condition, which means that the 2000-hour life test was successfully completed.

After 2000 hours of testing, the engine can still work normally, which means that the service life of the engine should be at least greater than 2000 hours.

Before the test, Li Tianfeng accurately estimated that the life of his engine should be at least more than 2000 hours, or even more than 3000 hours.

The new aero engine is assembled and qualified, and after the factory test run and leaves the factory, it is used in the field until the first overhaul is required.

After 2000 hours of life test, the first turn life of the turboshaft D engine can be positioned for at least 2000 hours, as for whether it can be positioned for 3000 hours in the future, and then 3000 hours of life verification test can be passed.

2000 hours!

What an achievement!

No wonder everyone is so happy, so excited, jumping and cheering, and the whole monitoring and control room is completely full of joy.

Outside, there was a crackling sound of firecrackers, the director of the test workshop, with a few employees, is setting off a large number of firecrackers outside the gate of the test workshop, which almost pushed the warm atmosphere to the top, and the employees of the entire test workshop were beaming!

The good news of the completion of the 2000-hour life test did not take long to spread throughout Tianfeng Technology Company, and when they heard such good news, the majority of employees were all happy, and their hearts were full of joy and pride.

The next day's "Songzhou Daily" reported on the front page, warmly congratulating Tianfeng Technology Co., Ltd. on the successful completion of the 2000-hour life test of the turboshaft D engine.

Such good news has not only spread throughout Tianfeng Technology Company, but also spread to Factory E and to the capital.

Li Tianfeng received congratulatory calls one after another, 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, I was about to report to you." ”

Zhang Haiping interrupted Li Tianfeng's words and said happily: "Tianfeng, I already know, congratulations, Shun lìtong guò 2000 hours life test, it's really exciting." ”

Zhang Haiping is well aware of the gold content of the 2000-hour life test, which not only creates 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, if it is smooth and smooth, it will be really exciting!" ”

"What, really have to carry out a 3000-hour life test, this, this is too exciting, if our turboshaft D engine through guò 3000 hours of life test, then this engine, will definitely be among the world's well-known turboshaft engines."

Li Tianfeng nodded, chatted with Zhang Haiping for a few minutes, and even talked about the airworthiness certification, about the vortex D airworthiness certification work, it has been started two months ago, and now there is a 2000-hour life test, the matter of certification, there should be no resistance, and there will be results soon.

Shun lì completed the 2000 hours of life test run without two days, this engine was transported back to the assembly workshop for decomposition, decomposition to the state of parts, each part will be strictly inspected, according to the inspection situation, to judge whether it can be increased for another 1000 small hand life test.

2000 hours, plus 1000 hours is 3000 hours, if you add another 1000 hours of life test is also smooth, which means that the first turn life of the turboshaft D engine can reach 3000 hours, to achieve such a first turn life, enough to compare with the world-famous turboshaft engine.
