The engine was not only seriously deformed, but also tattered, Li Tianfeng looked at it for a long time, but he couldn't see any clues, and I believe that others are the same.

Before this, there must have been many people who have seen it, and they should not have seen any fame, no, because there is basically no clue, Zhang Haiping pulled Li Tianfeng into the accident investigation team.

Li Tianfeng said: "Minister Zhang, our first priority is to find the analysis recorder on the plane and read the data inside. ”

Zhang Haiping said: "Yes, but this has to disassemble the wreckage of the plane, in addition, the plane fell like this, basically became scrap metal, I don't know if the analysis and recording instrument has also been damaged." ”

Everyone is basically the same, first of all, we must find the analysis and recording instruments, and since the opinions are agreed, then we will start to clean up and disassemble the wreckage.

To everyone's relief, the analysis recorder on the plane was found relatively smoothly, and the condition was relatively good, and after data reading, the abnormality was found.

Before the plane crashed, when the engine was stopped in the air, the engine torque was obviously abnormally large, and the torque was abnormal, which was the main reason for the engine to stop.

Li Tianfeng said: "Minister Zhang, it seems that the engine has been stuck, causing abnormal torque, the torque tester on the engine alarms, and the engine stops in the air for self-protection." ”

Zhang Haiping said: "No wonder, no wonder our fighters failed to restart the engine six times in a row in the air, it turned out that the engine was stuck." ”

Li Tianfeng said: "Minister Zhang, to find out the cause of the engine stagnation, I don't think it is difficult, according to my analysis, it is very likely that one or more of the main bearings of the engine have serious wear. ”

Another member of the accident analysis team next to him said, "Mr. Li, are you so sure? ”

Li Tianfeng affirmed: "I think it's the reason. And the way to find out the cause is very simple, just disassemble the engine wreckage, check the bearings and oil filter. ”

Zhang Haiping agreed: "Then do what Mr. Li said, and immediately disassemble the engine on the spot, although the engine is seriously deformed and tattered." But it is still possible to disassemble the bearings and other things. ”

So, several fighters, under the command of everyone, dismantled the engine, which was basically a destructive disassembly, because the engine was like this, and according to the normal disassembly, there was no way to carry it out.

Because the tools are relatively complete, there is Li Tianfeng's guidance by the side. The dismantling work is carried out very quickly, and the first thing to disassemble is the engine's several major lubricating oil filters, although these major lubricating oil filters are basically not the same, but they still have a certain analytical value.

One of the relatively good lubricating oil filters was successfully pulled out of the filter element, Li Tianfeng pointed to the metal chips on the filter element and said: "Minister Zhang, sure enough, the bearing is worn, you look at the metal chips." Typical bearing metal shavings. ”

Everyone leaned over to take a look and nodded in agreement. Before the engine was disassembled, there were still a few team members who were skeptical, but now seeing this situation, they know that Li Tianfeng's analysis is completely correct.

It took a lot of effort, and the big bearings of the engine were also disassembled, although the same bearing deformation was serious. But it does not affect everyone's judgment.

It is obvious that one of the bearings is seriously worn, and the other one also has a certain degree of wear.

Zhang Haiping said: "Mr. Li, your analysis is very correct, with your analysis. We immediately found the real reason for the engine stop. ”

One of the panelists, who is also obviously an expert in aero engines, said: "The main bearing of an aero engine is so important that it directly affects the service life and safety of the engine. ”

Another expert said: "Fortunately, fortunately, our domestic aero engines basically use bearings produced by Linhai Technology Company, and the bearings produced by Linhai Technology Company are very high-quality, and their quality is several points better than imported high-end bearings." ”

Some people agreed: "Linhai science and technology company production of aviation bearings, excellent quality, performance than imported better, the price is only the same as the price of imported bearings, our domestic several major aero engine manufacturers, basically use Linhai technology company into the production of bearings. ”

Humanitarian: "Linhai Technology Co., Ltd., or last year's top 500 manufacturing enterprises in China, is a very good, very well-known professional bearing production unit. ”

Li Tianfeng has a large number of shares in this group company, Li Tianfeng of course knows that Linhai Technology Group, every mistake, has now changed its name to Linhai Technology Group, a specialized bearing research and development and manufacturing group company, one of the top 500 Chinese manufacturing enterprises last year.

Now Linhai Science and Technology Group Co., Ltd., under the management of Zhao Linhai, and Li Tianfeng's technical guidance, the use of "Lee's process method" to produce bearings, the scale continues to expand, the types of bearings produced involve aviation, aerospace, ships, automobiles, machine tools and other fields.

Another expert asked: "Mr. Li, the engines produced by your Tianfeng Technology Company and the bearings used are all manufactured by Linhai Technology Company, right?" ”

Li Tianfeng said with a smile: "Of course, each of our engines, its bearings are all products of Linhai Technology Company. ”

Zhang Haiping said with a smile: "Experts, you may not know yet, Linhai Technology Company is also half of Mr. Li's enterprise, and Mr. Li holds nearly half of the shares of Linhai Technology Group. ”

"Ahh

The surrounding experts, surprised for a while, did not think that Li Tianfeng is still the shareholder of this very bullish and professional bearing company.

Li Tianfeng smiled happily.

Zhang Haiping was also in a good mood, and did not go deeper into this issue, but changed the conversation and said: "Now that we have found out the reason for the engine of this J-10 fighter to stop in the air, we will form a report, and I will report to the main head of the unit." ”

Immediately, an expert took the initiative to ask for help, and took the initiative to say: "Minister Zhang, I will draft this report!" ”

Zhang Haiping said happily: "Lao Zhao, then it's hard for you." ”

………

After listening to Zhang Haiping's report, the military chief once again pointed out that the aero engine must adhere to the road of localization.

After finding the cause of the failure, Li Tianfeng and his entourage returned to Tianfeng Technology Company.

The next day.

Li Tianfeng was in his office, received a phone call from Zhang Haiping from the capital, the cause of the accident was clear, Zhang Haiping also hurriedly returned to the capital, and immediately reported to the military for the first time, no, after the report was completed, early the next morning, Zhang Haiping called Li Tianfeng.

Zhang Haiping said: "Mr. Li, I worked hard for you yesterday, and you were scared. ”

Li Tianfeng said: "It's okay, it's okay, Minister Zhang, have you finished reporting to the leaders?" ”

Zhang Haiping said: "The report has been completed, the chiefs are very angry, but also once again made it clear that the aero engine must adhere to the road of localization, Mr. Li, in the next many years, Tianfeng Technology Company will be the focus of our military enterprises, you will also be one of the main equipment suppliers of our military." ”

Li Tianfeng was happy for a while, the military valued Tianfeng Technology Company, which Li Tianfeng was happy to see, and it was also very ideal.

Li Tianfeng said: "Minister Zhang, thank you for your concern. ”

Zhang Haiping nodded, and then reminded Li Tianfeng: "Mr. Li, you must be mentally prepared, because the leaders have instructed that the aero engine must adhere to the road of localization, so it is very likely that you will bear the heavy responsibility of developing the J-20 engine." ”

Li Tianfeng said: "Minister Zhang, the localization of the J-20 engine has not been carried out for several years, and as far as I know, we are developing a localized engine for the J-20 fighter in China. ”

Zhang Haiping said: "There is indeed such a thing, but there are too many technical problems and it is very difficult. ”

Develop power for the J-20!

Thinking about it, Li Tianfeng felt an irrepressible burst of excitement in his heart, the J-20 fighter, this is the most advanced fighter in China!

Zhang Haiping saw that Li Tianfeng was silent, thinking that Li Tianfeng felt that it was very difficult, Zhang Haiping comforted: "Mr. Li, this is a big project, if you are really responsible for the development, our military's support will be unprecedentedly huge, you can rest assured." ”

"In addition, I will also tell you the good news that several major military leaders have unanimously agreed not to import Russian-made engines for J-10 fighters."

This is indeed good news for Tianfeng Technology Company, which means that all J-10 fighters in the future will be equipped with turbofan 20 engines, and will no longer be equipped with Russian-made engines.

Li Tianfeng was happy for a while, and then said: "Minister Zhang, don't worry, if we let Tianfeng Technology Company undertake the power to develop the J-20 fighter, we will develop a fully qualified engine for the J-20 fighter!" ”

Li Tianfeng's confident answer made Zhang Haiping stunned, Zhang Haipinghai thought that Li Tianfeng felt that it was very difficult, but he didn't think about it, Li Tianfeng answered so confidently, and immediately, Zhang Haiping was surprised.

Zhang Haiping said with a little excitement: "Okay, good!" Mr. Li, I will immediately report to the chiefs, if nothing else, in the future, your Tianfeng Technology Company will take the lead to create an excellent power for our J-20 fighter! ”

Li Tianfeng said: "Minister Zhang, there is no problem, we will definitely develop an excellent power for our J-20!" Let our J-20 fighters soar into the blue sky and defend the airspace of our motherland! ”
