Tianfeng Technology Company.

Li Tianfeng was finishing reading a document, Sun Xiaoping knocked on the door and came in, Sun Xiaoping said: "Boss, there are three more samples of electronic components last time." ”

This type of sample, last time was two, the performance test was unqualified, Li Tianfeng and Gu Qingguo contacted, found out the reason for the disqualification, now, this model of the sample came to three pieces, these electronic components, very important, related to the turbofan 20 engine can really achieve localization, Sun Xiaoping also attaches great importance to the sample, as soon as the sample comes, immediately report to Li Tianfeng.

Li Tianfeng said: "Let's go, let's take a look at the performance testing of these three samples." ”

In the laboratory.

When Li Tianfeng and Sun Xiaoping entered the laboratory, the first sample was completing the preliminary performance test, and the second sample was also being tested.

When Bai Lijie, the director of the laboratory, saw Li Tianfeng and Sun Xiaoping, he immediately got up, Li Tianfeng waved his hand to signal Bai Lijie to sit down, and then asked, "Director Bai, how is the situation?" ”

Bai Lijie said: "Mr. Li, the first sample has been preliminarily tested and its performance is qualified, and the second piece will be tested soon." ”

Hearing this, Li Tianfeng's heart was light, the first one was qualified, this is a good start, indicating that the last two things must have been wrong in the No. 1257 connection node, and now that they are changed, the performance test will be qualified.

Li Tianfeng said: "Director Bai, continue to test, complete the testing of the second and third samples, I want to see the results." ”

Bai Lijie nodded, and then began to test seriously, while Li Tianfeng and Sun Xiaoping stood beside them, watching Bai Lijie and others test these samples.

The second sample test is completed, and the performance is qualified!

The third piece is also qualified!

A total of three samples, the preliminary test of performance is all qualified. Li Tianfeng's heart was relaxed for a while, in this way, the preliminary test of the performance of the several types of electronic components designed and commissioned by Gu Qingguo to manufacture was all qualified.

Sun Xiaoping was also happy in his heart, "Boss, the full-featured electronic digital control system of the turbofan 20 engine is completely localized. I don't think there's a big problem anymore. ”

These key electronic components are qualified, can be successfully manufactured, naturally for the localization of the clear obstacles, if further performance tests and comprehensive testing are qualified, then the real localization is basically no problem.

Li Tianfeng asked with concern: "Director Bai, what are the results of the performance test and comprehensive performance test of the previous models?" ”

Bai Lijie said: "Mr. Li, the comprehensive performance test has been completed, and the samples of these models are all qualified. The performance test is ongoing, and no problems have been found for the time being, all of which are within the qualified range. ”

Hearing this, Li Tianfeng was happy in his heart, it seemed that his design was still good, Gu Qingguo's strength in their research institute was also relatively strong, and the quality of these samples was first-class.

Li Tianfeng said: "Mr. Sun, you pay close attention to the performance test of these samples. Report back to me as soon as it's done. ”

Sun Xiaoping naturally agreed. Sun Xiaoping himself is also very concerned about the performance test, if the performance test is fully qualified, then the turbofan 20 engine full authority (full function) electronic digital control system localization is no longer barrier-free.

The full authority (full-functional) electronic digital control system of the turbofan 20 engine will be localized, and the subsequent turbofan 16, turbofan 17, and turbofan 18 will also be completely localized, as well as the complete localization of the turboshaft D and turboshaft E engines will also be implemented.

………

A comprehensive design review of the turbofan-20 engine organized by the military. It will be carried out in a few days, because it is the "106 Project", and there are many experts involved in the design review, involving various aspects, not only design experts. There are also experts in materials, electronics, processes, etc., which will be a very comprehensive and rigorous review.

It takes time for the expert group to be formed, and before the expert team came, the turbofan 16B engine design of Tianfeng Technology Company was also fully completed, and it took only one month from the beginning of the design to the completion of the design.

Because this is a modified design, on the basis of the turbofan 16 engine prototype, slight changes were made, and the workload was very small, mainly the size of the fan part, and the corresponding design changes of a small number of parts.

In one month, Li Tianfeng was very satisfied with the design of the turbofan 16B engine, so that there would be five months to carry out the trial production of parts and components, as well as the test run of the engine.

The trial production of parts, of course, only includes a few parts of the fan part, as well as the parts that have been modified in the design, and the number of parts that need to be trial-produced is very small, and the vast majority of the parts that have not undergone any design changes naturally do not need to be trial-produced.

The parts have not been changed in design, so they can naturally receive the parts directly from the warehouse and install them directly, without the trial production of parts at all.

The design review of the turbofan 16B engine can be organized internally by Tianfeng Technology Co., Ltd., and Li Tianfeng personally participates in the design review work, and the design review is passed at one time, and then begins to enter the trial production stage of the parts.

A few days later.

The huge expert group led by Zhang Haiping and served as the head of the design review expert group began to arrive at Tianfeng Technology Company.

Why is it a large group of experts, because the number of experts participating in the design review reached dozens, instead of a few experts or a dozen experts as before.

Many of the experts in the expert group are new faces to Li Tianfeng, but there are also many acquaintances, such as Zhang Hongzu of the Bureau of Science, Technology and Industry for National Defense, and Gu Qingguo.

There are also many experts in technology, there are several people, two of whom Li Tianfeng also knows, Feng Qirong and Zhou Yao, and they didn't think they could meet these two people.

A few years ago, when Li Tianfeng was still in Factory E, he participated in the National Aviation Industry System Technical Skills Competition, and there were two judges in the process group.

The turbofan 20 engine uses a full-featured electronic digital control system, and there are three electronic experts in the jury, of which Gu Qingguo is one of them.

In the large conference room of Tianfeng Technology Company, everyone met warmly, and Li Tianfeng shook hands with Zhang Haiping warmly.

In addition, there are seven or eight military personnel in the expert group, in addition to Zhang Haiping, a lieutenant general, there are also two major generals and several school officers.

Li Tianfeng said: "Minister Zhang, you are welcome to come in person, with your checks, our turbofan 20 engine will be more perfect in design." ”

Zhang Haiping said: "Mr. Li, you are modest, I know your technical strength." ”

Everyone met, greeted politely, and introduced, and then, Zhang Haiping, as the head of the group, began to announce the review procedures, as well as discipline, especially the discipline of confidentiality.

106 project, highly confidential, turbofan 20 engine design review, confidentiality is naturally the first, not the slightest leak, even the experts of the expert group, should not be recorded, some things can not be discussed outside after the completion of the review.

Zhang Haiping read out the confidentiality discipline with a serious face, read out the review process, everyone began to enter the working state, a large number of design data, process data, Tianfeng Technology Company has long been ready, but also prepared several conference rooms for the review.

The experts reviewed the information in these conference rooms, and if they needed to visit the site, Li Tianfeng also arranged escorts for everyone, and even Li Tianfeng himself could take everyone to the site to visit and see the trial production of the 20 parts of the turbofan.

Such a design review takes several days, and the design review of the turbofan 20 engine is the most important work of Tianfeng Technology in recent days.

………

Zhang Haiping and several military personnel, accompanied by Li Tianfeng, were watching the trial production of parts for the turbofan 20 engine in various subordinate workshops.

Zhang Haiping said: "Mr. Li, you have basically completed the trial production of parts for the turbine part, and the progress is really fast. ”

Li Tianfeng was a little happier, "The progress is relatively good, everything is relatively smooth, there are no obstacles, and there are no technical difficulties." ”

Zhang Haiping nodded, and then said: "Mr. Li, the amount of changes in your fan part is not small, let's go, let's take a look at the processing of fan blades." ”

Li Tianfeng said: "Minister Zhang, the fan blades of the turbofan 20 engine have not yet started trial production, but the process preparation work is almost the same, however, we can't see the trial production of the fan blades of the turbofan 20 engine, you can take a look at the manufacture of our turbofan 16 engine fan blades, there are a number of fan blades are being manufactured." ”

Fan blades, titanium alloy wide-chord hollow blades, using superplastic molding and diffusion connection process, two halves of titanium alloy blades, sandwiched with honeycomb in the middle, diffusion welding, and then after precision machining, a blade is processed.

Such an advanced technology, really mastered, looking at the whole country, is also Tianfeng Technology Company, so Zhang Haiping is very interested and wants to see it with his own eyes.

Li Tianfeng said: "Minister Zhang, then let's go, it's in the blade processing center next to it." ”

Under the leadership of Li Tianfeng, it took more than ten minutes for everyone to walk from the impeller machining center just now to the blade machining center next to it.

Zhang Haiping said: "Mr. Li, your factory is too big, you see, this large factory building, all tens of thousands of square meters, such a large factory, from this plant to another plant, it is really a little laborious." ”

A major general next to him said with a smile: "It seems that this factory is too big, and it also has drawbacks, and it is troublesome to walk, haha." ”

Li Tianfeng knew that everyone was joking, and he couldn't help but laugh, but he thought in his heart, the factory area is so large, with an area of more than 2,000 acres, it is really possible to consider adding some battery cars for employees to ride, and it is not possible to reduce it.

Zhang Haiping didn't mind taking a walk like this, and said with a smile: "It's okay for everyone to take a walk, and you can exercise by the way." ”

Today, we will continue to see three more, and the first one will be sent. (To be continued......)
