Li Tianfeng, Zhang Haiping, and no second person, the two of them were in the office, exchanging matters related to the use of the latest generation of all-digital electronic control system for the turbofan 20 engine.

Not only Zhang Haiping, but also the entire military has no objections to the design of the all-digital electronic control system, and they all agree with it, but there is a slight disagreement on the specific electronic components and sensors.

Zhang Haiping said: "The all-digital electronic control system of the turbofan 20 engine you designed, I took a serious look, it is very advanced, and we are very satisfied. ”

Li Tianfeng said: "Minister Zhang, what is your personal opinion?" ”

Zhang Haiping said: "If it is a personal opinion, I agree with your opinion, but I also need to consider the opinions of other comrades. ”

Li Tianfeng knew that the other comrades Zhang Haiping mentioned were all high-ranking members of the military, and their positions were basically the same as those of Zhang Haiping, and they were either major generals or lieutenant generals; if these people held opposing views, if Li Tianfeng could not convince the other side, then he really could not make his own opinions, and he had to follow their opinions.

Li Tianfeng said: "Minister Zhang, your personal views are the same as mine, things are much easier, for the all-digital electronic control system of the turbofan 20 engine, I advocate the use of all domestic electronic components and sensors, and can fully meet the design requirements." ”

Zhang Haiping said: "Mr. Li, some of our comrades in charge believe that the imported electronic components and sensors are of better quality and more reliable performance. ”

Li Tianfeng said: "Minister Zhang." I do not deny this, there are some imported electronic components and sensors whose performance and quality are indeed better than those made in China, but our turbofan 20 engine is a military aviation engine. What if there is a war and someone gets stuck in the neck? ”

Zhang Haiping said: "I have also taken this into consideration, and it is precisely because of this that I agree with your point of view, but some of our comrades in charge think so. This is peacetime, there will be no large-scale war for a long time to come, there is no question of being stuck in the neck. ”

Li Tianfeng said: "Director Zhang." We already have a relatively complete industrial system in China, even if the electronic components and sensors used in aviation can meet our requirements. ”

Zhang Haiping said: "Mr. Li, otherwise." As far as I know. Among the all-digital control system of the turbofan 20 engine, there are two key electronic components with extremely high technical requirements, according to our current domestic level, even if they are developed and manufactured, their quality and reliability are also worrying. ”

The turbofan 20 engine, the military put forward extremely high reliability and safety requirements, because if this engine is successfully developed, it will be the power of the J-10 fighter in the future. The J-10 fighter has only one engine, which is for the reliability and safety of the engine. More demanding than a two-engine fighter.

Those comrades in the military were also worried about this, so they asked Tianfeng Technology Company to use imported electronic components and sensors.

Li Tianfeng, who has decades of memory ahead of this era, has been deeply rooted in his design concepts, especially for the design of military aero engines, and its comprehensive localization and excellent craftsmanship.

In the event of a war, it is fully localized, so you don't have to worry about being stuck in the neck, and the excellent craftsmanship can not only ensure the excellent quality of the product, but also easily mass production.

Li Tianfeng said: "Minister Zhang, there are indeed two key electronic components, if according to our current domestic technical strength and level, even if they are manufactured, there are problems in safety and reliability, which cannot meet our requirements, but for the two key electronic components, our Tianfeng Technology Company is ready to design it by itself." ”

"Design your own!" Zhang Haiping glanced at Li Tianfeng in surprise, and then said, "Mr. Li, can you also design this aspect?" ”

Li Tianfeng nodded confidently: "There is no problem in this regard, we Tianfeng Technology Company will design, and then entrust a domestic electronic component manufacturing enterprise with excellent technology and manufacturing to produce and manufacture." ”

Zhang Haiping said with emotion: "Mr. Li, I didn't expect that electronics is also your strength, as long as you can complete the design, there will be no problem with manufacturing, we still have several large-scale electronic component manufacturing enterprises in China, and I will contact you with the best and most suitable one." ”

Li Tianfeng said: "Director Zhang, then thank you, this matter is settled." ”

Zhang Haiping said: "Mr. Li, it seems that I am going to be a lobbyist for you this time to persuade our comrades." ”

Li Tianfeng said: "Director Zhang, then please leave it to you." ”

Zhang Haiping smiled and said: "It doesn't matter, you have the design drawings of these two key electronic components, and I am very sure to convince these comrades, otherwise, I have no choice." ”

The matter was basically finalized, the new generation of all-digital electronic control system of the turbofan 20 engine all used domestic electronic components and sensors, and the two talked for a long time about this all-digital electronic control system.

Finally, the two chatted about the engine monitoring system.

Previously, the turboshaft D and turboshaft E engines produced by Tianfeng Technology Company were not equipped with such a monitoring system, while the civilian turbofan 16, turbofan 17 and turbofan 18 engines were installed with an engine monitoring system.

It is a state-of-the-art engine monitoring system that captures engine operating parameters, including temperature, pressure, speed, flow and vibration levels, by installing 25 sensors in the fans, intermediate and high-pressure compressors, and high-, medium- and low-pressure turbines of the aircraft's engines.

In this way, Tianfeng Technology Company can know the working condition of each engine of turbofan 16, turbofan 17 and turbofan 18.

This set of engine monitoring system can obtain engine information at the ground station through the data and information system on the aircraft, and then through the satellite data link.

The circumstances of the transmission of information are, respectively, the time of take-off, landing and cruise of the aircraft; engine index situation; A summary of what happened after the plane landed, and so on. As long as the aircraft is still in the flight phase and the engine is still working, data will be transmitted back to the monitoring center of Tianfeng Technology.

However, the monitoring system of the turbofan 16, turbofan 17 and turbofan 18 engines, considering the technical difficulty and cost constraints, does not include the location information of the engine.

Li Tianfeng introduced this monitoring system to Zhang Haiping, and then, Li Tianfeng said: "Minister Zhang, we believe that the turbofan 20 engine must be installed with such a monitoring system, and it is still a more advanced monitoring system than the turbofan 16, turbofan 17 and turbofan 18 engine monitoring system. ”

"Oh." Zhang Haiping's eyes lit up and said: "This is not bad, with such a set of monitoring system, the working situation of each engine, we can be clear, Mr. Li, tell me your thoughts, for the turbofan 20 engine, what kind of monitoring system are you going to design." ”

Li Tianfeng said: "The engine monitoring system is not new, but the monitoring system we designed for the turbofan 20 engine will be very advanced, and it is planned to link with the Beidou satellite system, which can not only transmit back the detailed data of the engine, but also locate each engine, so that the J-10 fighter equipped with the turbofan 20 engine will also be clear in which position......

After listening to Li Tianfeng's introduction, Zhang Haiping said happily: "Mr. Li, with such a set of monitoring system, it is very convenient, I agree, in this way, I will report to the superior immediately after a while, our turbofan 20 engine adopts such a monitoring system." ”

Hearing this, Li Tianfeng was also happy in his heart, if the turbofan 20 engine has such an advanced engine monitoring system, the turbofan 20 engine will go up a notch.

In Zhang Haiping's office, Li Tianfeng stayed for a long time, and the two talked a lot about the technical issues of the turbofan 20 engine.

Looking at the time, Li Tianfeng got up and said, "Minister Zhang, then don't bother." ”

Zhang Haiping said enthusiastically: "Mr. Li, since you are here, you will eat before leaving, I have already ordered to go down, and I have prepared a meal, although there is no wine, but we can drink a little drink." ”

The military is disciplined, you can't drink alcohol at noon, Zhang Haiping prepared drinks, and at noon, the two of them were in the military's small canteen, a few good specialties, plus a little drink, and they also ate very happily.

After eating, Li Tianfeng said: "Minister Zhang, if you have time, you often come to Tianfeng Technology Company to have a look." ”

Zhang Haiping said briskly: "Mr. Li, I am very optimistic about the turbofan 20 engine, if I have time, I will come uninvited." ”

Hearing this, Li Tianfeng smiled happily.

Zhang Haiping was very enthusiastic and personally sent Li Tianfeng to the door of the General Staff Department, where Zhang Haiping had already arranged a military off-road car and was ready to send Li Tianfeng off-road.

The two were about to shake hands and say goodbye, and Li Tianfeng was also about to get into the car, but at this time, the guard who followed Zhang Haiping stepped forward quickly, "Chief, your phone." ”

As soon as Zhang Haiping answered the phone, his face changed slightly, "um, um" A few times he hung up the phone quickly, and then said with a solemn face: "Mr. Li, let's go to the AVIC Group Headquarters Hospital together." ”
