The engine reaches its maximum output power state, and time passes by one second, and the time data on the display is also jumping rapidly.

Usually, a few seconds are simply a matter of blinking an eye. Generally no one cares about this time, but today is different. It seems that every second is so long, and many pairs of eyes keep staring at this value.

Two minutes, 120 seconds, it seems like half a century has passed today. It is really half a century. Two minutes later, the maximum power state test run was completed, the engine was turned off, and the sound of the entire engine working suddenly stopped. The engine rotor continued to rotate under the action of inertia, but it would slowly stop.

At this moment, everyone felt relieved. At this moment, everyone knew that the maximum test run state had been completed, the engine had undergone the strictest test run state assessment, and everything was normal.

Li Tianfeng waved his hand happily and said loudly: "The maximum power test run is normal!"

"Test run is normal!"

It took two or three seconds before everyone could react. Suddenly, there were bursts of warm applause from the entire surveillance control room, and some people even jumped up with joy.

The test run commander also said loudly: "The engine re-turn is normal, and the specified re-turn time is exceeded."

As the boss of Tianfeng Technology Company, Li Tianfeng said loudly: "Now I announce that the second verification test run has been successfully completed!"

"Oh, too! The test run was completed successfully!"

Suddenly, several young people jumped up, especially a young test craftsman, who shouted with joy, jumped up to the sky with exaggeration, and waved his fists hard, venting all the tension and worries in his heart just now.

Qiu Wen'an and Sun Xiaoping looked at each other, and they also felt inexplicably light and smiled happily. At this moment, Qiu Wen'an quietly let go of his tight right hand, and the heart of his right hand was covered in sweat.

As the chief designer of this engine, Qiu Wen'an knew it was not easy to maintain the maximum power state for two minutes. Often the problem occurred at this time. Fortunately, he passed the test run smoothly and completed the test run perfectly.

Li Tianfeng was also happy and walked out of the monitoring and control room surrounded by everyone. The second verification test was much smoother than the first time. If Li Tianfeng guessed correctly, there should be no major problems when the engine was broken down again and the parts were inspected again, and there might not be even a few small problems.

The second verification test run is completed. The next work is to decompose the engine and then carefully inspect the parts. If there is no problem, the engine will be assembled again and the third verification test run will be conducted again.

The third verification test run will greatly increase the difficulty. It is no longer a half-day test run, but a thirty-hour verification test run. The thirty-hour test run is a severe assessment of the engine, so this kind of test run is also called an assessment test run.

Of course, the third test run is a matter of the future, even after the verification test run is completed, there is no problem with the parts being strictly inspected, everything goes smoothly, and the fastest speed is also a matter of half a month later.

The sound of the engine test drive just now was clearly heard within the entire test drive factory of more than 200 acres. Employees who did not see the test drive with their own eyes were closely watching this test drive.

When the test drive was about to get off work at noon, the sound of the test drive stopped and everything became quiet. The employees started to inquire curiously and stopped. Was the test drive completed successfully or was it because of some problem that the test drive was interrupted?

A middle-aged employee pulled Xiao Zhao, a test drive technician who came out of the test drive monitoring room just now, and pulled Xiao Zhao aside. Without waiting for the middle-aged employee to ask, several employees soon surrounded him, and several employees were quickly surrounding him not far away.

Pulling Xiao Zhao, the middle-aged employee asked with concern: "Xiao Zhao, how is the test drive situation?"

Xiao Zhao smiled and said, "Let me take a sip of water and fuck me to death."

All morning, I stayed in the test drive monitoring room. Xiao Zhao really had no chance to drink water. Just now, after the thrilling maximum power test drive, Xiao Zhao had already had a dry mouth.

When everyone could wait to let Xiao Zhao run to drink water, an employee brought his own water cup from the table next to him and said, "Xiao Zhao, it's clean. After drinking, I'll tell us about the situation of the test drive just now."

"Yes, yes, hurry up and talk to us, I'm so anxious."

Seeing that everyone was looking at him and surrounding him, Xiao Zhao couldn't help but smile and didn't dislike him. Maybe he was really too thirsty. He finished half a glass of water like a cow drink, and didn't have time to wipe the tea on his mouth. He quickly said, "Don't worry, don't worry, our second verification test run was very smooth and a complete success!"

Successful success!

Suddenly, everyone cheered and some even shouted happily, as if they were happier and more excited than they won the super prize.

After a long time, everyone cheered and everyone looked at Xiao Zhao again. The middle-aged employee who had just pulled Xiao Zhao over said, "Xiao Zhao, you were at the test drive site just now, let's talk to us about the specific situation of the test drive just now."

Seeing that everyone was looking at him with a gaze, Xiao Zhao did not refuse and immediately began to tell the situation just now vividly. When it was about the happy point, everyone cheered and when it was about the nervous point, everyone was sweating.

Of course, Xiao Zhao has studied confidentiality regulations, and Xiao Zhao has not disclosed some places that need to be kept confidential, such as test run data, specific performance, etc.

Xiao Zhao spoke very wonderfully. When he was about to finish his speech, Xiao Zhao realized that there were many people around him, inside and outside the three layers. Everyone pricked up their ears and listened to their own test drive with their eyes illuminating.

...

Capital.

Zhang Haiping was sitting on the sofa opposite Zhang Haiping. The two were smoking and chatting. It seemed that they had a good relationship and were having a happy chat. From time to time, they laughed happily.

"Lao Zhang, I think you often look at the information about a turboshaft engine. Which research institute is developing the engine."

Zhang Haiping smiled and said, "Lao Hu, this is the turboshaft engine of Tianfeng Technology Company that you often mention. If you are interested, I will give you the information and you can take a look."

Hu Delong said: "It is the engine with an output power of 1800kw, a power-to-weight ratio of 9, and a 4th generation turboshaft engine."

Zhang Haiping said: "Lao Hu, you know a lot."

Hu Delong said: "Old Zhang, is it really possible for Tianfeng Technology to develop such an advanced turboshaft engine?"

Zhang Haiping nodded and said, "It's not possible, but it's certainly possible. I'm full of confidence in them."

Hu Delong looked at Zhang Haiping in shock and said in confusion: "Old Zhang, they really have this strength. You are so confident in them."

Zhang Haiping said: "Lao Hu, do you know that Tianfeng Technology Company just completed the second verification test run, which was very smooth and the test run was very successful."

As an insider, Hu Delong was quite familiar with aircraft engines. He was shocked and said in disbelief: "They completed the second verification test drive so quickly. I remember that Lao Zhang, you went to Tianfeng Technology Company in person a month ago. At that time, they only had the first verification test drive."

Zhang Haiping nodded: "Tianfeng Technology Company has indeed completed the second verification test drive, it is absolutely true."

The second verification test run was successfully completed, and Hu Delong knew more clearly and couldn't help but become interested. "Old Zhang, borrow the information of Tianfeng Technology's turboshaft engine for a few days."

Zhang Haiping said happily and very readily: "No problem." After saying that, he gave Hu Delong a thick stack of information. These information were collected and sorted by Zhang Haiping himself. Although there was no specific engine design data, some basic performance data and some introductions were relatively comprehensive. Obviously, Zhang Haiping spent a lot of effort.

After taking the thick information, Hu Delong couldn't help but look through it. After a moment of looking, he immediately became interested. After reading it for a few minutes, after gaining a preliminary understanding, Hu Delong said: "This engine is so advanced, at least half a generation ahead of the most advanced turboshaft C engine in China."

The turboshaft C engine is known as the third and a half generations, while Tianfeng Technology's turboshaft engine is the real fourth generation. It is indeed at least half generation ahead, and it is still a half generation that cannot be surpassed. There is a qualitative difference between the two.

Hu Delong said with emotion: "It is not easy for Tianfeng Technology to develop such an advanced turboshaft engine, but it is a pity that they are a private enterprise."

Zhang Haiping naturally knew what this meant, and couldn't help but say: "Lao Hu, we can't be so pessimistic about the problem. Tianfeng Technology is a private enterprise, but neither the laws nor the policies clearly prohibit private enterprises from developing aviation engines. On the contrary, since a few years ago, the above has been emphasizing and encouraging the integration of military and civilians and common development."

Hu Delong said: "That's right, but there are some people who are not as enlightened as you and me. On the contrary, they are very stubborn. If Tianfeng Technology wants to obtain a production license and pass the airworthiness certification, it will be very difficult, or even impossible to pass it."

Upon hearing this, Zhang Haiping nodded, his face a little solemn. If Tianfeng Technology Company really cannot obtain a production license and cannot pass the airworthiness certification, it means that this engine will die prematurely or there will be some changes.

After sighing, Zhang Haiping said, "I can only do it step by step, complete a series of test drives first. I will spare no effort to help Tianfeng Technology if I have the following things."

...

Tianfeng Technology Company.

Li Tianfeng may have considered future things, but now, Li Tianfeng's main energy is on the test drive of this engine, and he will consider the production license, airworthiness certification and other matters later.

At this time, the engine has completed the decomposition work after the test run. The parts have been cleaned and are ready for strict inspection after the second test run.
