The electronic control system of this turbofan 20 engine was previously designed in accordance with the basic performance requirements of the military, and it was not fully localized.

In fact, Li Tianfeng has long wanted to implement localization in his heart, and last time, he personally went to the capital to have in-depth communication with Zhang Haiping, and now, coupled with the fact that the military has agreed to fully localize, coupled with such a small change in the purchase of equipment.

This strengthens Li Tianfeng's belief that this complete set of electronic control systems must be fully and truly localized, and all parts, including electronic components and sensors, must be all made in China, or manufactured by Tianfeng Technology Company.

Some electronic components and sensors have been changed, and the electronic control system of the whole engine should also be changed accordingly in the design.

Understanding what Li Tianfeng meant, Sun Xiaoping said: "Boss, all the electronic components and sensors are made of domestic ones, and I am worried that there will be a certain decline in reliability and quality." ”

Li Tianfeng said: "This is not necessarily true, we have formed a complete industrial system in China, and the quality of some things is not worse than that of imports, of course, we also have to take this into account, in case the quality of domestic electronic components and sensors is slightly worse, what should we do." ”

Qiu Wen'an said: "Boss, at this point, we can prevent it from the design, but in this way, the design of this complete set of engine electronic control system will almost be pushed to the beginning, and the design cycle will be relatively long." ”

Sun Xiaoping was also worried: "Boss, if it is fully domestic, some electronic components and sensors are really not available in China." This kind of high-end stuff is in the hands of European and American countries. ”

Li Tianfeng said: "It is precisely because there is no domestic thing, things are in the hands of others, I am more determined to implement comprehensive localization, my plan is to turbofan 20 engine real localization." Most of the parts are manufactured by Tianfeng Technology Company, and the parts that need to be purchased from outside must also be domestic. ”

Seeing that Li Tianfeng was so firm, Sun Xiaoping and Qiu Wenan glanced at each other, nodded, and said at the same time: "Boss, since the tone has been set like this, we will do it according to such a request." ”

An aero engine, involving parts. Large and small, varied, tens of thousands, all parts are produced by Tianfeng Technology, which is unrealistic.

Li Tianfeng means that he produces most of the parts, and the other parts, including those electronic components and sensors, are all made of domestic parts.

Li Tianfeng said: "The electronic control system of the turbofan 20 engine is partially localized. Among them, there are some electronic components and sensors that are not available in China, and there are things that are not available in this part. I designed it myself, and I also designed the entire electronic control system. ”

Sun Xiaoping said: "Boss, I didn't think about it, you are not only proficient in machinery, but also proficient in materials. is also proficient in electronic and electrical, compared with you, the gap between us and you is really not ordinary. ”

Li Tianfeng smiled and said: "An excellent aero engine designer must be proficient in mechanics, materials, electronics and other aspects, which are essential skills. ”

And then. As soon as the conversation changed, Li Tianfeng said: "I will personally complete the overall design plan of the entire electronic control system of the turbofan 20 engine, and then, you will carry out the specific design according to my plan, and you must hurry up in time." ”

Everyone nodded and promised that they must seize the time to design, ensure quality and quantity, and complete the design of the electronic control system of the turbofan 20 engine as soon as possible.

End of meeting.

Li Tianfeng returned to his office and greatly modified the design of the electronic control system of the turbofan 20 engine he had previously designed, and on this basis, made changes and improvements to achieve full localization.

There are some electronic components and sensors that are not available in China for the time being, or the quality is unstable, Li Tianfeng personally designed them, and after the design drawings of these parts are completed, he will find the most suitable and powerful manufacturers in China to manufacture.

At the beginning, Zhang Haiping had promised to find the best domestic manufacturer for Li Tianfeng to process and manufacture on his behalf, and Li Tianfeng did not need to worry about this, Li Tianfeng only needed to do a good job in design, and the manufacturing work would be handed over to these manufacturers contacted by Zhang Haiping.

On the basis of the original to improve and perfect, the workload is not as huge as imagined, because it is only the overall design scheme, does not involve specific design details, a few days of effort, this set of new electronic control system overall design scheme is freshly baked.

When the new design plan is sent, the design team led by Sun Xiaoping and Qiu Wenan will naturally carry out a comprehensive and specific design, and after these designs are completed, Li Tianfeng can carry out the final checks.

In the whole set of new design schemes, when communicating with Zhang Haiping, Li Tianfeng began to design the two key electronic devices that Zhang Haiping said.

In addition, there are several other electronic components and sensors, although there are also in China, but Li Tianfeng decided to design his own after inquiring with professional eyes. Li Tianfeng's design is definitely better and better in terms of performance and quality than the existing ones.

Embraer.

in the office.

Marceldo was meeting with an important person, a GE executive, who had been talking in his office for some time.

The senior executive comrade said: "Mr. Marceldo, if your company significantly reduces the engine share of Tianfeng Technology Company, our company promises that we can carry out further cooperation, including providing you with our engines at a more favorable price." ”

The representative of Pratt & Whitney has just left, and only a few days after the company, GE executives have come again, and Marceldo now understands that the original target is Tianfeng Technology.

To be honest, Marceldo recognizes the engines produced by Tianfeng Technology Company very much, especially with the purchase and equipment of Tianfeng Technology Company's engines, with a deeper understanding of these engines, Marceldo is more optimistic about Tianfeng Technology Company's engines.

Now, seeing this senior comrade say this, Marceldo thought to himself, it is your engine, not long ago, there was an incident of engine smoke and emergency landing, which caused a lot of adverse effects on Embraer.

However, although Marceldo is dissatisfied in his heart, as an old fritter in the mall, he will never show these dissatisfaction on his face.

On the contrary, Marcel laughed and said, "If your company is really sincere, we can talk about it further." ”

Hearing this, the senior management comrades were very happy and revealed another news, "Mr. Marceldo, in the face of the increasingly competitive regional airliner engine market, we are starting to develop a new engine with better performance. ”

Marcel said: "Your company is really willing to invest, such an engine, at least billions of dollars will be invested, I don't know when it will be successfully developed." ”

"According to our company's technical strength, this engine can be delivered to customers in two or three years at most. ”

As a businessman, Marceldo didn't want to offend either Tianfeng Technology or GE, so he laughed and said, "Then congratulations, if your engine is really good, we will be very interested." ”

The senior comrade was also very happy, and he also smiled, and then said: "Mr. Marceldo, what do you think of the matter I just mentioned about reducing the engine share of Tianfeng Technology Company?" ”

Marcel pondered and said: "This matter, in the end, it has to be discussed by the board of directors, you also know that the quality and performance of Tianfeng Technology's engine are very good, and the market and customers have responded very well." ”

Hearing this, the face of this senior executive comrade of GE changed slightly, after talking for so long, he was tricked, Marceldo was actually proficient in Chinese Tai Chi, and after beating down Tai Chi, he pushed the problem to the board of directors again, and his words were in vain.

In addition, Marceldo's attitude is very good, and his speech is impeccable, and the senior comrades can only feel aggrieved in their hearts, not a little angry, and they must maintain a smile on their faces.

If Li Tianfeng was next to him, he would definitely laugh happily three times, Marceldo is really a good comrade.

Capital.

Zhang Haiping's office.

This time, Li Tianfeng came to the capital again, on the one hand, to take a look at Wang Ruobing, and on the other hand, to hand over the design drawings designed by himself to Zhang Haiping.

Li Tianfeng said: "Minister Zhang, then please, this is all the electronic components and sensors required for the electronic control system of the turbofan 20 engine, there are a total of six design drawings of electronic components, and a total of two design drawings of sensors. ”

After taking over such a USB drive from Li Tianfeng's hand, Zhang Haiping said: "Mr. Li, you're welcome, we're all for the turbofan 20 engine." ”

Zhang Haiping said: "Don't worry, I will definitely look for the most powerful manufacturer in China and make samples of these things as soon as possible." ”

Li Tianfeng said: "That's the best, after the sample is manufactured, we still have to go through strict performance testing tests, fully qualified, fully meet our design requirements, these things can be installed in our turbofan 20 engine electronic control system." ”

Zhang Haiping nodded, and then said: "Mr. Li, I have rarely received calls from you during this period of time, and I don't know how the design progress of the turbofan 20 engine is." ”

Li Tianfeng smiled a lot and said: "Minister Zhang, during this period of time, I have been busy with the design of the electronic control system of the turbofan 20 engine, and I forgot to report to you the progress of the turbofan 20 engine. ”

Zhang Haiping said: "Mr. Li, between our old friends, there is no talk of reporting or not reporting, we communicate with each other, by the way, Mr. Li, the electronic control system of the turbofan 20 engine, including the design drawings of these electronic components and sensors, are all designed by you?" ”
