Tianfeng Technology Company.

It has been a little time for the turbofan 20 engine to enter the comprehensive design stage, and Li Tianfeng has also personally designed a lot of parts, some parts are specifically designed by Li Tianfeng, and there are also some parts Li Tianfeng just roughly drew a design sketch.

Li Tianfeng knows his own design team, its design level and technical level very well, as long as there are these design sketches, we will definitely be able to design qualified and satisfactory parts in the end.

Aero Engine R&D Center.

Cai Xiaoqi is a chief designer, there are a large number of designers under his hands, including several chief designers, as well as a lot of ordinary designers, in the entire design of the fourth room, Cai Xiaoqi himself can be regarded as the backbone of the design, from time to time, some difficult design drawings, Cai Xiaoqi will design himself.

Tianfeng Technology Co., Ltd.'s aero engine R&D center (formerly known as aero engine design institute) has more than a dozen design offices, of which the fourth design room is mainly responsible for the design of the turbine part.

Next to Cai Xiaoqi, there is a design sketch drawn on A3 white paper, which is the design sketch of the turbine case, the entire turbine part has been changed to the minimum, and many parts are basically the same as the turbine of the turbofan 16 engine.

The turbine casing is the part of the turbine that has changed the most, Li Tianfeng drew a design sketch and handed it to Sun Xiaoping, and now Cai Xiaoqi will carry out a specific design on this basis, and after the design is completed, it will definitely go through many reviews, modifications and improvements.

In front of this design sketch, on my computer, I am carefully drawing the design drawing, and while drawing the design drawing, I have to stop from time to time to calculate and think.

Cai Xiaoqi thought in his heart, fortunately, there is a design sketch drawn by Mr. Li, and the key part has been marked with dimensions and technical conditions. There is also a turbofan 16 engine turbine box for reference, otherwise, I really can't take this technical job.

Xiao Liu, who was next to him, couldn't help but be curious when he saw that Cai Xiaoqi was actually immersed in design, instead of reviewing the design drawings he handed in. I immediately came over.

Xiao Liu said: "Head, this is the turbine casing design of the turbofan 20 engine, this is the design sketch, it's so beautiful, head, this is what you drew yourself!" ”

Hearing this, Xiao Wang next to him also came over curiously, looked at the design sketch, looked at Cai Xiaoqi with admiration and said, "Head." I didn't see it, you can't stop making a shot, once you shoot, it's extraordinary, this design sketch reflects the skills, we can only admire! ”

Cai Xiaoqi smiled, and then said, "You don't think that this design sketch was drawn by me, right?" ”

Xiao Liu and Xiao Wang glanced at each other, and then said in unison: "Head, didn't you draw it?" ”

The two immediately thought of Sun Xiaoping. He added: "Head, could it be that Sun personally drew it?" I can't see that Sun's basic skills are so solid. ”

Another person next to him also came over, and it seemed that it should be a supervising designer under Cai Xiaoqi's hand, and the supervising designer said: "Xiao Liu, Xiao Wang, Sun Suo is an older generation of college students." When they went to school, they didn't have a computer, so they drew by hand, and it was possible to draw such a highly skilled design sketch. ”

Cai Xiaoqi smiled, and then said: "There is nothing wrong with this design sketch given to me by Sun Shu himself. But it was definitely not drawn by Sun himself. ”

It wasn't drawn by Sun!

Everyone looked at Cai Xiaoqi together, full of surprise, this design sketch was not drawn by Sun Xiaoping, is it? In everyone's mind, a person's name came to mind, and when they remembered this name, everyone looked at each other again.

At this moment, everyone's eyes are full of admiration, all those who have been in the factory for two or three years, especially those who are engaged in technology, who don't know, Li Tianfeng's technology is strong, and he is the idol in everyone's hearts.

Xiao Liu said with a look of admiration: "Head, is this design sketch drawn by Mr. Li himself?" Such technical skills are amazing! ”

Cai Xiaoqi also said with admiration: "That's right, this is the design sketch drawn by Mr. Li himself, not only has a solid technical foundation, but also has a very high technical level. ”

Suddenly, everyone gathered around and looked at this design sketch, and while looking at it, everyone was amazed and amazed.

In fact, Li Tianfeng has drawn dozens of such design sketches recently, and all of these design sketches have been distributed and handed over to some relatively high-level designers, such as chief designers, chief designers, and even some office directors to design in person.

Turbofan 20 engine, on the basis of the turbofan 16 engine core engine derivative design, between the two, there are a lot of commonalities, some parts directly and turbofan 16 engine common, there are some parts on the basis of the turbofan 16 engine for scale design, a small number of parts to a certain degree of change and improvement.

The parts with a relatively small degree of change and little technical difficulty are designed by a group of designers below, and the parts with a relatively large degree of change or slightly more technical difficulty are drawn by Li Tianfeng himself, and everyone designs according to the design.

Some parts with great design difficulty and technical content, Li Tianfeng personally designed and personally designed detailed design drawings.

Because of this, Li Tianfeng proposed at the first design conference that the comprehensive design of the turbofan 20 engine should be completed within six months.

Tianfeng Technology Co., Ltd. is carrying out the comprehensive design of the turbofan 20 engine, and the design work is carried out in an orderly manner, and everything is relatively smooth, but in the E factory, a big thing has happened.

………

In the past two days, Yang Xianfeng felt very irritable, and he didn't think that such a thing would happen, and if such a thing spread, his face would be lost.

The explosion incident actually occurred in the factory, which is really embarrassing. The turbine casing of the turboshaft C engine has been entrusted to Tianfeng Technology Company for OEM processing in the past, and the processing quality has been excellent, and the supply is also very timely.

The turbine casing is definitely a key and important part in the engine, and the reason why such key parts are entrusted to Tianfeng Technology Company for processing is mainly because the processing quality of E factory has been unstable and difficult to process, among which precision casting is the most difficult, and the part qualification rate is the lowest.

According to Duan Hongjiu's requirements, now, after these parts are recovered, they are all processed by Factory E themselves, so that the problem comes, not only the processing quality is extremely poor, the pass rate is extremely low, but also makes Yang Xianfeng and Liu Qingshan anxious.

What's even more irritating is that an explosion occurred during the precision casting process of the turbine casing, resulting in three injuries, one of whom was not seriously injured, and is still in the intensive care unit of the hospital, not out of danger of life.

Liu Qingshan was also frustrated, "Mr. Yang, it's all my fault, the technical management is not strict, and now there is such a thing." ”

Yang Xianfeng waved his hand and said: "Mr. Liu, this matter has little to do with you, if it weren't for that blind command, how could such a thing happen." ”

"Hey." Liu Qingshan sighed.

Things started yesterday, the precision casting workshop of E factory was preparing to cast the turbine casing of the turboshaft C engine, and it happened that Duan Hongjiu was checking the sanitary situation in the precision casting center, and when he saw the precision casting of the casing, he was suddenly interested.

Duan Hongjiu didn't understand technology at all, so he did give on-site guidance, and the workshop director of the precision casting workshop actually followed Duan Hongjiu's "instructions" in order to cater to Duan Hongjiu, and did it one by one.

In this way, the problem comes, the process parameters are seriously wrong, originally, the process rigor of aviation products cannot be changed at will, but with Duan Hongjiu, the number one leader, plus a workshop director who is ready to hug his thighs and pat himself, then everything is different.

The process parameters are seriously wrong, especially the humidity is seriously exceeded, when the high-temperature molten metal is poured, an explosion occurs, although the explosion is not very violent, but the hot molten metal splashes at high temperature, causing three workers to be injured.

Yang Xianfeng thought in his heart, damn it, why didn't you blow up Duan Hongjiu, a bastard.

Liu Qingshan said: "Mr. Yang, I think the workshop director of the precision workshop must be replaced." ”

Yang Xianfeng said: "Mr. Liu, you bring up this matter at the next office meeting, we must take down the director of this workshop, in addition, this matter, I must report to the group company, it is too unusual." ”

Now, there are many people in Factory E who know that Yang Xianfeng and Duan Hong have been at odds for a long time, and there are a large number of people around them, and Yang Xianfeng is mainly surrounded by local cadres.

………

Li Tianfeng heard about the explosion accident in Factory E, and it was also the next day that Yang Xianfeng called and learned from Yang Xianfeng's mouth.

Li Tianfeng was also speechless for a while, and completely looked down on this Duan Hongjiu in his heart, this is a blind command, you are an administrative cadre, what are you doing in command of technical things, you think you are a technical strongman like your brother.

Li Tianfeng comforted Yang Xianfeng on the phone, and then proposed to call Hu Lianggu out and everyone get together. Hu Lianggu is the representative of the general army of Factory E, and his relationship with Li Tianfeng is okay, if Hu Lianggu and Yang Xianfeng join forces, it is conceivable that Duan Hongjiu will definitely add to the blockage.

However, the matter of Factory E is just a small episode for Li Tianfeng, Li Tianfeng's main energy is the research and development of turbofan 20 engines, as well as the sales of his own engines, to further open up the international market.

Xu Lilong is in Canada, and he calls back every day to report the situation, and judging from Xu Lilong's report, Li Tianfeng feels that it is a game.

Li Tianfeng even thought in his heart that it would be great if Bombardier also ordered a large number of its own engines.

However, Li Tianfeng didn't think that Embraer was very fast and was ready to leave for Tianfeng Technology Company from Brazil.
