This electronic control system for the turbofan 20 engine was previously designed according to the basic performance requirements of the military and was not fully domestically produced.

In fact, Li Tianfeng had long wanted to implement localization in his heart. Last time, he went to Beijing to conduct in-depth communication with Zhang Haiping. Now, the military has agreed to be fully localized, and there are such a small change in equipment procurement this time.

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

Some electronic components and sensors have been changed, and the design of the entire engine's electronic control system also needs to be changed accordingly. Li Tianfeng personally presided over the meeting. Not only did several design backbones engaged in this system design call over, but Sun Xiaoping and Qiu Wen'an also participated in it.

Understanding Li Tianfeng's meaning, Sun Xiaoping said: "Boss, I have changed all domestic electronic components and sensors. I am worried that there will be some decline in reliability and quality."

Li Tianfeng said: "This is not the case. We have formed a complete industrial system in China, and the quality of some things is not worse than that of imported ones. Of course, we must also consider this. What should we do if the quality of domestic electronic components and sensors is slightly worse."

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

Sun Xiaoping also said worriedly: "Boss, if it is fully domestic, some electronic components and sensors are not available in China. Such high-end things are in the hands of European and American countries."

Li Tianfeng said: "It is precisely because there is no in China that things are in the hands of others. I am more determined to promote comprehensive domesticization. My plan is to truly localize the turbofan 20 engine, and most of the parts we are producing and manufacturing, and the parts that need to be purchased from outside must also be domestic."

Seeing Li Tianfeng so firm, Sun Xiaoping and Qiu Wen'an looked at each other and nodded. They said at the same time: "Boss, since the tone has been settled, we will do this according to this requirement."

An aircraft engine involves parts of all sizes, various sizes, and tens of thousands of yuan in quantity. It is unrealistic to have all the parts produced by Tianfeng Technology.

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

Li Tianfeng said: "The electronic control system of the turbofan 20 engine is partially domestically produced, and some electronic components and sensors do not exist in China, and this part does not exist. I personally designed it, and in addition, the entire electronic control system is also designed by me."

Sun Xiaoping said: "Boss, I didn't think that you are not only proficient in machinery, materials, and electronics. Compared with you, the gap is really not that big."

Li Tianfeng smiled and said, "A good aviation engine designer must be proficient in machinery, materials, electronics and other aspects. This is a necessary skill."

Then, after a turn of the topic, Li Tianfeng said: "I will personally complete the overall design plan for the entire electronic control system of the turbofan 20 engine. Then, you can develop the specific design according to my plan, and you must hurry up in terms of time."

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

The meeting ends.

Li Tianfeng returned to his office and made major modifications and designs to the electronic control system of the turbofan 20 engine he designed before. On this basis, he made changes and improvements to achieve comprehensive domestic production.

There are currently no electronic components and sensors in China or with unstable quality. Li Tianfeng personally designed them. After the design drawings of these parts are completed, he will find the most suitable and most powerful manufacturers in China to manufacture them.

At the beginning, Zhang Haiping had promised to find the best domestic manufacturers to process and manufacture for Li Tianfeng. Li Tianfeng didn’t need to worry about this. Li Tianfeng just had to do a good job of designing it, and the manufacturing work was handed over to the manufacturers Zhang Haiping contacted.

The workload of improvement and improvement on the original basis is not as huge as imagined, because it is just the overall design plan and does not involve specific design details. In a few days, this new electronic control system overall design plan has been released.

If the new design plan continues, the design team led by Sun Xiaoping and Qiu Wen'an will carry out comprehensive and specific designs. After these designs are completed, Li Tianfeng will only conduct the final inspection.

Among the entire new design plan, when communicating with Zhang Haiping, Li Tianfeng began the design work of the two key electronic devices that Zhang Haiping mentioned.

In addition, there are several other electronic components and sensors. Although there are also domestic ones, Li Tianfeng decided to design them himself after searching with his professional eye viewing. The performance and quality designed by Li Tianfeng are definitely better and better than the existing ones.

Embraer.

In the office.

Marceldo is meeting an important figure, an executive of Ge Company, and the two have been talking in the office for a while.

The executive said: "Mr. Marceldo, if your company reduces the engine share of Tianfeng Technology, 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 Company just left. The company was just a few days ago, and the executives of GE Company came again. Marceldo now understands that his original target is Tianfeng Technology Company.

To be honest, Marceldo highly recognizes the engines produced by Tianfeng Technology Company, especially with the purchase and equipment of Tianfeng Technology Company's engines, as he understands these engines more deeply, Marceldo is more optimistic about Tianfeng Technology Company's engines.

Now, seeing this senior executive say this, Marceldo thought to himself, it is your engine. Not long ago, the engine smoked and urgent landings have caused considerable adverse effects on Embraer.

However, although Marceldo was dissatisfied, as a veteran in the mall, he would never show these dissatisfactions on his face.

On the contrary, Marceldo laughed and said, "If your company really has such sincerity, we can talk further."

Upon hearing this, the executives were very happy and revealed another news, "Mr. Marceldo, facing the increasingly fierce regional passenger aircraft engine market, we are starting to develop a brand new and better performance engine."

Marceldo said: "Your company is really willing to invest in it. You can invest at least billions of dollars in such an engine. 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 a maximum of two or three years," said the executive.

As a businessman, Marceldo neither wants to offend Tianfeng Technology nor Ge Company. So he laughed and said, "Then congratulations to you, if your engine is really great, we will be very interested."

The senior executive was also very happy, smiled, and then said, "Mr. Marceldo, what do you think of reducing the engine share of Tianfeng Technology as I just mentioned?"

Marceldo pondered and said, "This matter is finally discussed by the board of directors. You also know that the engines of Tianfeng Technology are of very good quality and performance, and the market and customers are very good."

Upon hearing this, the face of this senior executive of Ge Company changed slightly. After talking for so long, he was fooled. Marceldo was proficient in Chinese Tai Chi. After hitting Tai Chi, he pushed the problem to the board of directors again, and his words were wasted.

In addition, Marceldo has a very good attitude and speaks impeccably. The executives can only feel depressed and cannot get angry, and they must keep a smile on their faces.

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

Capital.

Zhang Haiping's office.

This time, Li Tianfeng came to the capital again. On the one hand, he took a look at Wang Ruobing, and on the other hand, he handed the design drawings he had designed to Zhang Haiping.

Li Tianfeng said: "Minister Zhang, please let me know. These are all electronic components and sensors needed for the electronic control system of the turbofan 20 engine. There are six design drawings for electronic components and two design drawings for sensors."

After taking such a USB flash drive from Li Tianfeng, 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 manufacturers in China and make samples of these things as soon as possible."

Li Tianfeng said: "That's the best. After the samples are manufactured, we have undergone strict performance testing and are fully qualified and fully meet our design requirements. Only then can these things be installed on our turbofan 20 engine electronic control system."

Zhang Haiping clicked a little and said, "Mr. Li, I rarely received calls from you during this period. I don't know how the design progress of the turbofan 20 engine is."

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

Zhang Haiping said: "Mr. Li, we old friends can't talk about reporting or not reporting. We communicate with each other. By the way, Mr. Li, the electronic control system of the turbofan 20 engine, including these design drawings of electronic components and sensors, are all designed by you?"
