The test control center, on the huge LCD screen, represents the curve of air humidity, and soon climbed, the air humidity from 30%, 40%, to 50, and continues to rise!

Many people, through the huge double-glazed glass of the control center, saw that hoarfrost and ice cubes appeared on many floors of the high-altitude platform.

"The engine anti-icing device has been successfully activated!"

Seeing this, many people are nervous and relieved, once the anti-icing device is turned on, the fan part of the engine will be heated, and part of the hot air from the compressor will enter the fan to prevent freezing.

"Zoom in!"

Li Tianfeng did not stand in front of the huge glass anymore, but went to a liquid crystal display in front of the test bench, which has a high-definition camera, and this LCD screen is showing the air intake part of the engine, and the fan can be seen rotating at high speed.

This is a high-definition camera, the lens is zoomed in, you can see more clearly, the engine air intake, as well as the fan, are clean, without any icing test.

"Oh also! That's great! ”

Sun Xiaoping and Qiu Wen'an waved their fists vigorously and jumped up happily, the engine performed well, and in such a low-temperature and high-humidity environment, there was no icing at all.

After the anti-icing verification was completed, it was followed by the ice swallowing test, high-altitude surge test, high-altitude parking restart test, and so on.

This engine, in the high-altitude test bench, very comprehensive and strict carried out a series of tests, high-altitude platform test, a total of more than a week.

Li Tianfeng, in addition to paying attention to the development of his second-generation core machine, basically stayed here this week, watching the turbofan 20 engine complete a series of high-altitude simulation tests.

When all the high-altitude simulation test runs are completed, the engine gradually stops, and the high-altitude platform returns to the long-term temperature and atmospheric pressure state on the ground.

Li Tianfeng officially announced. The high-altitude simulation test of the turbofan 20 engine was a complete success!

Suddenly, many people cheered happily, and Sun Xiaoping, Qiu Wenan and others were also happy and excited. But as a cadre, it is impossible to be like those test takers and technicians, jumping and shouting to vividly express their feelings.

Everyone applauded violently and vigorously, including their excitement and joy in this applause, and the applause was very warm and enduring.

Li Tianfeng is the same as everyone else. Energetic, happy applause.

The turbofan 20 engine completed a series of test runs, including ground test and high-altitude simulation test runs, and the whole test performance was very perfect and excellent, which indicates that this engine was successfully developed!

No wonder everyone is so happy, those test drivers and technicians. When Li Tianfeng announced the success of the test, everyone jumped up with joy. Cheers vigorously.

After more than a year of hard work, there are finally fruitful results, heavy fruits, at this moment, everyone is completely immersed in the joy of success and harvest.

Turbofan 20 engine, successfully completed a series of test runs. This is like a gust of spring breeze, which blew all over the entire Tianfeng Technology Company in an instant.

"We made it!"

"So happy! This is the most exciting news this year! ”

"Haha, that's amazing! It's so cool! ”

“……”

The majority of employees of Tianfeng Technology Company heard the good news. As if it was like the New Year's holiday, everyone was completely immersed in joy, and the hottest topic of the entire Tianfeng Technology Company for several days was the turbofan 20 engine.

Those experts and technical elites who have been drawn from major scientific research institutions across the country and have only joined Tianfeng Technology Company for one or two months have heard such exciting news, and their hearts are also bursting with inexplicable excitement and joy, and they will share this success with everyone.

The engine completed a series of test runs in the test engineering center, and after the test run, a series of disassembly inspections were completed in the assembly workshop, and it was found that the engine was normal.

Li Tianfeng is very happy that he has finally completed an important task.

At this moment, Li Tianfeng was in his office, reporting the good news to Zhang Haiping, Li Tianfeng was on the phone, laughing, fully reflecting the joy and joy in his heart.

Obviously, Zhang Haiping completely felt this joy, and Zhang Haiping said happily: "Mr. Li, you are in such a good mood, there is a happy event?" ”

Li Tianfeng said: "Minister Zhang, great joy, I am about to report good news to you, our turbofan 20 engine has successfully completed a series of verification tests, including 150 hours of ground long test, and a series of very strict and comprehensive high-altitude simulation tests. ”

"Ahh Zhang Haiping's inexplicable surprise!

Complete the 150-hour ground test!

Complete the high-altitude simulation test!

Zhang Haiping knows what this portends, which means that the turbofan 20 engine has been successfully developed!

All of a sudden, Zhang Haiping became excited and asked excitedly: "Mr. Li, does this mean that our turbofan 20 engine has been successfully developed?" ”

Li Tianfeng said: "Yes, the development has been successful!" ”

"Okay, great!" Zhang Haiping was happy, very happy in his heart, happy with a strong excitement, Zhang Haiping said: "Mr. Li, I will immediately organize experts, and I will personally serve as the leader of the expert group, and I want Ma Shan to accept the turbofan 20 engine." ”

Li Tianfeng knew that the military was in urgent need of a turbofan-20 engine, and at present, the number of Jian-10 and Jian-11 fighters equipped by the troops was not small, and it was not a long-term strategy to always import engines from Lao Maozi.

Li Tianfeng said: "Minister Zhang, welcome the acceptance of the expert group!" ”

Zhang Haiping said happily: "Okay, we'll see you in a few days." ”

………

Zhang Haiping is very efficient, just three days, three days later, Zhang Haiping personally led a team, composed of more than a dozen experts, arrived at Tianfeng Technology Company, began to carry out a comprehensive acceptance of the turbofan 20 engine.

The acceptance was very comprehensive and careful, and the expert group stayed in Tianfeng Technology Company for five days, and these five days, from all aspects, fully accepted the turbofan 20 engine.

Of course, in addition to leading the team to accept the turbofan 20 engine, Zhang Haiping specially looked at the design of the second-generation core engine of Tianfeng Technology Company.

This is the military's 771 project, Zhang Haiping naturally attaches great importance to it, and is very happy to see that the design work is in full swing and progressing smoothly.

In the combustion chamber design room, Zhang Haiping looked at the three-dimensional design drawing of the combustion chamber design. A lead designer, demonstrating on a computer.

Using the design software, in front of Zhang Haiping, the parts are assembled one by one, and finally assembled into a complete engine combustion chamber, including flame cylinder, combustion chamber, nozzle and so on.

In addition to the assembly of the combustion chamber part, professional software is also used to simulate the working state of the combustion chamber, the fuel is sprayed from the nozzle, ignition, and the combustion chamber works.

Zhang Haiping said on the spot: "Mr. Li, I didn't think about it, your combustion chamber part has been designed, not bad, not bad!" ”

Li Tianfeng said: "Minister Zhang, the design of the combustion chamber is very advanced, but for us, it is a mature technology, and the combustion chamber of the RQ2000 gas turbine engine can be directly translated, and the amount of change is not large. ”

Zhang Haiping not only looked at the design of the combustion chamber, but also looked at the design of other major components in detail, such as fans, compressors, turbines and other parts.

Seeing the design of the turbine part, Zhang Haiping also specially asked a lot of questions, the design of the turbine part is very advanced, which is a high-load and high-efficiency turbine, guide vane, working blade, the aerodynamic performance design of the blade type, cooling design, and turbofan 16 and other engines are very different.

In addition, Zhang Haiping also looked at the "Hercules" material, personally watched the material performance test, and saw this material with his own eyes, Zhang Haiping was excited again.

In addition to excitement and joy, Zhang Haiping repeatedly emphasized that we must do a good job of technical confidentiality and never leak secrets. There is no need to remind him, Li Tianfeng naturally knows that confidentiality comes first.

The acceptance and review of the turbofan 20 lasted five days and passed smoothly, and the experts of the expert group unanimously assessed that the overall performance and main parameters of the turbofan 20 engine comprehensively exceeded a series of technical requirements put forward by the military.

Everyone also agreed that this engine comprehensively surpasses the current Russian-made engine of the J-10, and everyone made it clear that the engine can soon enter mass production and can be equipped with troops.

After the acceptance review was successfully completed and Zhang Haiping returned to the capital, the production license of the turbofan 20 engine was also quickly lowered, which was obviously a special case.

After obtaining the production license, the turbofan 20 engine was immediately mass-produced, and the production of the first batch of 5 engines was immediately put into operation and started.

In the first half of this year, the monthly output of turbofan 20 engines may be twenty or thirty units, and in the second half of this year, the monthly output of turbofan 20 engines may double.

By next year, the monthly output of turbofan 20 engines may increase, Li Tianfeng knows that the military has a great demand for this engine, and most of the active fighters may be equipped with turbofan 20 engines, such as J-10, J-11 and so on.

Successfully obtained the production license and successfully entered mass production, Li Tianfeng also began to fulfill his original promise, began to reward meritorious deeds, and evaluated the meritorious figures and outstanding figures in the development process of the turbofan 20 engine.

When the turbofan 20 engine was developed, the selection was carried out every month when the evaluation details were issued in an official document.

Now, the winners are selected by summarizing the results of each previous month's evaluation. Li Tianfeng personally checked the selection work, and it was completely data-based to ensure fairness and openness.

In front of the propaganda column of Tianfeng Technology Company, there are crowds of people, the water is impassable, there are three layers inside and three layers outside, everyone is surrounding in front of the propaganda board, looking at the selection results.
