When the engine reaches its maximum power output, the time passes by and the number of hours on the display jumps rapidly.

Normally, a few seconds is a blink of an eye, and usually no one cares about this time, but today is different, as if every second is so long, how many pairs of eyes have been staring at this value.

Two minutes, 120 seconds, such a short time seems to have passed half a century today, it is really half a century, two minutes later, the maximum power state test is completed, the engine is turned off, the sound of the whole engine working suddenly stopped, the engine rotor under the action of inertia, continue to rotate, but will slowly stop.

At this moment, we all put down a high heart, at this moment, we know that the maximum test state has been completed, and the engine has undergone the most stringent test state assessment, and it is normal.

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

"Test run normal!"

After a full two or three seconds, everyone reacted, and suddenly, the entire monitoring and control room resounded with bursts of warm applause, and some people even jumped up happily.

The test commander also said loudly: "The engine residual rotation is normal, and the specified residual rotation time is exceeded." ”

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

"Oh also! The test run was successfully completed! ”

Suddenly, several young people jumped up, especially a young test technician, who shouted with joy, exaggerated to jump high, jumped into the air, and waved his fist vigorously. Vent all the tension and worry in your heart just now.

Qiu Wenan and Sun Xiaoping glanced at each other, and the two of them were also inexplicably light in their hearts, and smiled happily, at this moment, Qiu Wenan quietly let go of his clenched right hand, which was in the palm of his right hand. Covered in sweat.

As the chief designer of this engine, Qiu Wenan knows that it is not easy to maintain the maximum power state for two minutes, and often problems will appear at this time.

Li Tianfeng's heart was also happy, and he walked out of the monitoring and control room under the support of everyone, and the second verification test was much smoother than the first time. If Li Tianfeng's guess is correct, when the engine is disassembled again and the parts are inspected again, there should not be any major problems, and there may not be many minor problems.

After the second validation test is completed, the next step is to disassemble the engine and then inspect the parts strictly and carefully if there are no problems. The engine will be assembled again and the third validation test will be carried out again.

Third validation test. The difficulty should be greatly increased, no longer half a day to complete the test, but to carry out 30 hours of verification test, 30 hours of test, is a severe assessment of the engine, so this test is also called assessment test.

Of course. The third test run is a matter of the future, even after the completion of this verification test, there is no problem with the parts after strict inspection, and the fastest speed is half a month later.

The sound of the engine test just now. The entire 200 acres of test plant range is clearly audible, and the employees who have not seen the test situation with their own eyes are paying close attention to this test run.

Seeing that at noon, the sound of the test stopped and quieted down, and the employees began to inquire curiously, whether the test was successfully completed or interrupted because of some problems.

A middle-aged employee pulled Xiao Zhao, the test technician who came out of the test monitoring room just now, pulled Xiao Zhao aside, and without waiting for the middle-aged employee to ask, several employees soon came up, and several employees were walking up not far away.

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

Xiao Zhao smiled and said, "Let me drink a sip of water, it will kill me." ”

All morning, stayed in the test monitoring room, Xiao Zhao really didn't have the opportunity to drink water, just now, after the thrilling maximum power state test, Xiao Zhao had a dry mouth.

Where can everyone wait for Xiao Zhao to run to drink water, an employee took his own water cup from the table next to him and said: "Xiao Zhao, clean, after drinking, let's quickly talk about the test just now." ”

"Yes, yes, tell us about it, I'm in a hurry."

Xiao Zhao saw that everyone was looking at him and surrounding him, he couldn't help but smile, and he didn't dislike it, maybe he was really too thirsty, and he drank most of the glass of water like a cow, and he didn't have time to wipe the tea on his mouth, so he hurriedly said: "You don't have to worry, don't worry, our second verification test is very smooth, and it was a complete success!" ”

A complete success!

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

After a long time, after everyone cheered, everyone looked at Xiao Zhao again, and the middle-aged employee who pulled Xiao Zhao over just now said: "Xiao Zhao, you were at the test site just now, tell us about the specific situation of the test just now." ”

Seeing that everyone was looking at him with blank eyes, Xiao Zhao did not shirk, and immediately began to tell the situation just now, talking about the happy place, everyone cheered for a while, and when it came to the nervous place, everyone was sweating.

Of course, Xiao Zhao has studied the confidentiality regulations, and some places that need to be kept secret, such as the number of test cars, specific performance, etc., Xiao Zhao does not disclose.

Xiao Zhao spoke very wonderfully, when he was about to finish, Xiao Zhao found that there were many people around him on the three layers and the outer three layers, and everyone pricked up their ears and listened to themselves talk about the test car with bright eyes.

……

Capital.

Zhang Haiping is in his office, on the sofa opposite Zhang Haiping, there is a middle-aged man, the two are smoking and chatting, it seems that the relationship between the two is good, and the chat is relatively happy, from time to time, the two also laugh heartily.

"Lao Zhang, I see that you are often looking at the information of 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 I often mention to you, if you are interested, I will give you the information, and you can also take a look." ”

Hu Delong said: "It is the engine with an output of 1800KW and a power-to-weight ratio of 9, which is known as the fourth-generation turboshaft engine. ”

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

Hu Delong said: "Lao 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 will definitely be possible, I have full confidence in them." ”

Hu Delong looked at Zhang Haiping in astonishment, and said puzzledly: "Lao Zhang, they really have this strength, you are so confident in them." ”

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

As an industry insider, Hu Delong is also relatively familiar with aero engines, and he couldn't help but be surprised and said in disbelief: "They completed the second verification test so quickly, I remember that a month ago, Lao Zhang, you went to Tianfeng Technology Company in person, and they only verified the test run for the first time at that time." ”

Zhang Haiping nodded: "Tianfeng Technology Company has indeed completed the second verification test, which is true." ”

Shun lì successfully completed the second verification test, what does this mean, Hu Delong is more clear, and can't help but be interested, "Lao Zhang, lend me the information of Tianfeng Technology's turboshaft engine for a few days." ”

Zhang Haiping was happy and said very cheerfully: "There is no problem." After speaking, Hu Delong was given a thick stack of information, these materials were collected and sorted out by Zhang Haiping personally, although there was no specific design of the engine, but some basic performance numbers, some introductions were relatively comprehensive, obviously, Zhang Haiping spent a lot of effort.

After receiving the thick information, Hu Delong couldn't help but look at it, and after a little look, he immediately became interested, and after watching it for a few minutes, after having 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, and the turboshaft engine of Tianfeng Technology is the fourth generation, which is indeed at least half a generation ahead, and it is still a half generation that cannot be crossed, and 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 they are a private enterprise, which is a pity." ”

Zhang Haiping naturally knew what this meant by pity, and couldn't help but say: "Lao Hu, we can't be so pessimistic about the problem, Tianfeng Technology is a good private enterprise, but the law and policy do not explicitly prohibit private enterprises from developing aero engines, on the contrary, since a few years ago, the above has been emphasizing and encouraging the combination of military and civilian development and common development." ”

Hu Delong said: "That's what I said, but there are some people who are not as open-minded as you and me, on the contrary, very stubborn, Tianfeng Technology wants to obtain a production license and pass the guò airworthiness certification, but I am afraid that it will be very difficult, or even impossible to pass at all." ”

Hearing this, Zhang Haiping nodded, his face was a little dignified, if Tianfeng Technology Company really can't obtain a production license and can't pass the guò airworthiness certification, it means that this engine will die prematurely, or there will be some changes.

Sighing, Zhang Haiping said: "I can only take it step by step, first complete a series of test runs, and then talk about the things that follow, I will spare no effort to help Tianfeng Technology." ”

……

Tianfeng Technology Company.

Li Tianfeng may have thought about the future, but now, Li Tianfeng's main focus is on the test run of this engine, and he will consider it later on production licenses, airworthiness certifications and other things.

At this point, the engine has completed the disassembly after the test run, and the parts have been cleaned and ready for the rigorous inspection after the second test run.

Today's two watches, the second one is sent! (To be continued......)
