Li Tianfeng looked very carefully, and even took out a five-fold magnifying glass from his desk and looked at the impact site for a long time.

"The design of the blades is good, and the machining quality is good." Li Tianfeng nodded, thinking in his heart.

This is a titanium alloy wide-chord hollow blade, which not only has superior aerodynamic performance, but also is strong, sturdy, and has super anti-impact ability.

After looking at these two fan blades, Li Tianfeng thought in his heart, this test flight at the plateau airport, by mistake, this flying bird hit the fan blades, and inadvertently, made a collision verification for the turbofan 16 engine.

Originally, Li Tianfeng was still thinking about when the foreign body impact verification of the engine would start to be done.

………

It's September.

The production license of the turbofan 16 engine also came down last month, and Li Tianfeng personally went to the capital to get back this gratifying production license, which indicates that the turbofan 16 engine can start mass production.

The verification test flight of the turbofan 16 engine is also nearing the end, whether it is on the Yun-8K transport aircraft or on the C919 aircraft, the performance is very good, the commercial aviation company is very satisfied, and the military is even more satisfied.

No, Minister Liu of the General Assembly personally called Li Tianfeng, and in the words, Minister Liu was full of praise and happiness, and after answering the call, Li Tianfeng was in a very good mood.

The two turbofan 16 engines provided to the H-6 have also been shipped out of Tianfeng Technology last week, and it will not be long before the H-6 modified by Tongguò will be equipped with these two turbofan 16 engines for test flights.

After obtaining the production license, Li Tianfeng's pressure has also been greatly reduced, and since last month, Li Tianfeng has often received calls from Embraer. began to urge himself to deliver engines according to the requirements of the order, and at the Zhuhai Air Show, Embraer placed an order for hundreds of engines.

With the production license in hand, Tianfeng Technology Company began mass production of turbofan 16 engines, and the "TFWS002" turbofan engine has been tested through a series of factory verifications. Tianfeng Technology also submitted an application for design finalization.

The expert group has come to Tianfeng Technology Co., Ltd. half a month ago to conduct a three-day design review of the "TFWS002" turbofan engine, and the experts of the expert group still have a high evaluation of the "TFWS002" turbofan engine.

Li Tianfeng estimates that the design certificate of this engine should also come down. If Shun Lì gets the design certificate, it will be an important milestone in the development of this engine, and the pressure in Li Tianfeng's heart will be further reduced.

Embraer not only called Guò to urge the delivery of the turbofan 16 engine, but also the delivery of the TFWS002 turbofan engine.

Thinking of the "TFWS002" turbofan engine design certificate, Li Tianfeng was ready to take the initiative to ask.

Zhang Hongzu is the deputy leader of the "TFWS002" turbofan engine design review expert group. Li Tianfeng called the Bureau of Science, Technology and Industry for National Defense.

As soon as the phone rang, Li Tianfeng smiled and said, "Expert Zhang, hello." ”

Zhang Hongzu also smiled heartily, "Mr. Li, I am about to inquire about the design certificate, I am about to call you to sue you." ”

Li Tianfeng suddenly said: "Expert Zhang, are you saying that the matter of the design certificate has a result?" ”

Zhang Hongzu said: "Mr. Li, your 'TFWS002' turbofan engine. It's a very good 20,000-pound thrust turbofan engine, such an engine. Naturally, the design must be finalized and the design certificate ......"

Zhang Hongzu was very talkative on the phone, said a lot, praised enthusiastically, and then. Zhang Hongzu said: "Mr. Li, congratulations, the 'TFWS002' turbofan engine has been officially finalized in the country, codenamed 'turbofan 17', immediately following the code name of your turbofan 16 engine. The design certificate has just been issued by our director. ”

Hearing this, Li Tianfeng was overjoyed!

Turbofan 17! Not bad, not bad, so much hard work, from the design, to the processing of parts, the assembly of the engine, a series of factory verification tests, finally there are results, there are gains.

Suddenly, Li Tianfeng was overjoyed and said happily: "Expert Zhang, thank you, this is great news for us!" ”

Zhang Hongzu smiled heartily, "Mr. Li, you should make persistent efforts to finalize the design of the TFWS003' turbofan engine." ”

Li Tianfeng said: "Definitely, definitely, in another two or three months, after sufficient parts processing and verification, and a series of tests, the first prototype of this engine will also enter the assembly." ”

Zhang Hongzu said: "Mr. Li, you are good, this progress is very fast." ”

Li Tianfeng said: "The progress is still relatively smooth, and it is estimated that the test run of the first engine of this engine will start before the end of this year." ”

The two chatted for a long time on the phone, and then, Li Tianfeng pressed the button on his desk with great interest, Liu Wei knocked on the door, and walked in quickly.

Liu Wei said: "Boss, what's the matter?" ”

The joy on Li Tianfeng's face was thick, and he was still immersed in the joy just now, and said happily: "Mr. Liu, our 'TFWS002' turbofan engine has been designed and finalized, and the design certificate has been issued. ”

Liu Wei was overjoyed: "Boss, the design has been finalized, it's great!" ”

Li Tianfeng said: "The engine code is 'turbofan 17', which is followed by the code name of our turbofan 16 engine. ”

Liu Wei said happily: "Boss, if our 'TFWS003' turbofan engine progresses faster, the engine code may be turbofan 18!" ”

Li Tianfeng said: "It is very likely that our 'TFWS003' turbofan engine may be the future turbofan 18, so that it is a serial number, turbofan 16, 17, 18, a total of three turbofan engines." ”

Liu Wei said happily: "Boss, I will immediately prepare for the commendation meeting of meritorious personnel, this is really good news, turbofan 17 engine, I believe that the majority of employees will be very happy to know this good news." ”

"Hmm." Li Tianfeng nodded and said, "Such good news will be announced immediately, so that everyone will be happy." ”

As Liu Wei happily walked out of Li Tianfeng's office, the news immediately spread like wings, and soon spread throughout Tianfeng Technology Company.

"Our 'TFWS002' turbofan engine has been officially approved by the state, codenamed turbofan 17!"

"It's so cool, Lao Zhang, I heard that there will be a commendation meeting for meritorious personnel, and Mr. Li will be rewarded for the meritorious figures in the development of the engine!"

"Well, there is such a thing, Lao Liu, in the development process of the turbofan 17 engine, your performance is good, and you may be rated as a meritorious person."

"Lao Zhang, you're not bad."

“……”

The majority of employees of Tianfeng Technology Company, everyone is dancing with eyebrows, beaming, as if the New Year, according to the convention, at the gate of Tianfeng Technology Company, dozens of barrels of ceremonial flowers were set off in the earth-shattering sound.

After the ceremony, a huge red banner was hung directly above the factory gate, which was very eye-catching, even from a distance, even on Songzhou Avenue in the distance.

"Warmly celebrate the success of the national project of the "TFWS002" turbofan engine! Shun lì obtained the design certificate! ”

As soon as the huge banner was hung up, coupled with the earth-shattering sound of fireworks just now, the big red scraps of paper at the gate of the factory were very festive, and many people noticed this scene.

"Tianfeng Technology Company is amazing! Another engine has been developed! ”

"It's still a turbofan engine, it's amazing!"

"I'm so envious of them!"

“……”

In the office, Li Tianfeng has always been happy, and he is even happier than the last time the turbofan 16 engine obtained the production license.

Li Tianfeng was happily answering one phone call after another, and whoever said that a good thing would not go out, and the good news spread throughout Songzhou City almost instantly.

Guo Tongde called, Zhu Maohua from Factory E called, and now, Yang Xianfeng's phone also called.

Yang Xianfeng said: "Tianfeng, congratulations, congratulations!" ”

Li Tianfeng said happily: "Mr. Yang, thank you, and at the same time congratulate you." ”

Yang Xianfeng laughed and said, "Tianfeng, you are really well-informed, however, the official text has not come down yet, and it will take a few days to find out in the end." ”

Li Tianfeng said: "Mr. Yang, this matter is a sure thing, Mr. Zhu is about to be promoted, Mr. Yang is promoted to the general manager of Factory E, Mr. Yang, you can invite me to drink at that time." ”

Yang Xianfeng couldn't hide his joy in his heart, Yang Xianfeng had just returned from the capital yesterday, and the organization conversation had ended, so Li Tianfeng said that it was a matter of nail in the class.

The two congratulated each other on the phone, they were very happy, and Yang Xianfeng ended the call, Li Tianfeng sat in his boss's chair in a good mood, and thought in his heart, the 'TFWS002' turbofan engine has been officially approved by the state, codenamed turbofan 17, and he has taken another solid step.

The company is developing bigger and bigger, Li Tianfeng is happy, and at the same time he thought in his heart, the turbofan 16 engine, the turbofan 17 engine, plus the 'TFWS003' turbofan engine being developed, is really good!

Li Tianfeng thought of these three engines in his mind, and couldn't help waving his fists vigorously, with a strong sense of accomplishment in his heart.
