After basically cooling, the door of the sintering test equipment was opened, and Chen Weiping personally took out the sintered sample from the equipment.

The remaining warmth was dissipated. Li Tianfeng wore white gloves and took the sample to see it himself, and even brought a magnifying glass. At this time, Li Tianfeng was far from letting go of his heart. After carefully looking at it, Li Tianfeng was basically relieved.

At least, there is no big problem with this sample from the appearance. Li Tianfeng gave the sample to Chen Weiping and said, "Mr. Chen, you can take a closer look."

After taking this sample, Chen Weiping also looked carefully and seriously. In Chen Weiping's opinion, this is the research result of his own countless trials over the past few months, and Chen Weiping is most concerned about this sample.

After looking at the sample for a long time, he even took a magnifying glass and looked carefully. Chen Weipin said: "Mr. Li, from the appearance, this sample is very good."

Li Tianfeng nodded, "I also think there is no problem with the appearance at least, but the performance needs to be detailed inspection and performance analysis."

Chen Weiping immediately said: "Xiao Liu, come here and conduct detailed inspections on this sample immediately!"

A young man came over in a white coat and left with the sample, obviously performing performance inspections as required.

Li Tianfeng knew that the test results would take a long time to come out, and Li Tianfeng was not going to wait here anymore. So Li Tianfeng stood up and said, "Mr. Chen, tell me immediately if there is a test result."

Chen Weiping immediately said, "Mr. Li, don't worry, as soon as I came out, I'll send it to your office."

Li Tianfeng nodded and left the Materials Engineering Center. In Li Tianfeng's mind, this ceramic-based composite material is crucial.

There are several important and critical factors for whether this turbofan engine is successfully developed. Among them, the high-quality aviation bearings mentioned above are one factor. In addition, several new materials are also crucial, such as the ceramic-based material just now.

As for the design of turbofan engines, Li Tianfeng's technical level is there. He has decades ahead of this era, and he knows clearly the development direction of future aviation engines, the fifth, sixth, and even the seventh generation aviation engines.

The upgrade of aeronautical engines is related to new materials. Without new materials, Li Tianfeng cannot develop advanced aeronautical engines. It is hard to cook without rice!

In the afternoon.

Chen Weiping did send the test results in person. Judging from Chen Weiping's expression, it seemed that the result was not very satisfactory.

Sure enough, after taking the test results, Li Tianfeng found that several indicators were unqualified, and one of them was also a key indicator. Although it was not far from being qualified, it was still unqualified.

After reading the test report, Li Tianfeng said: "Mr. Chen is still unqualified!"

Chen Weiping said: "Mr. Li. Let's try it again and improve the ratio."

Li Tianfeng put down the test results and said in his heart that, indeed, this ceramic base material is really difficult to develop, and it is still in the test stage. After so many repeated tests, it has not yet reached a full pass.

After thinking about it, Li Tianfeng said: "Mr. Chen, improve the ratio in this way, and increase the No. 3 substance by 0.5%. Correspondingly, the No. 7 substance by 0.5%, and the sintering temperature will increase by ten degrees, and the time will increase by fifteen minutes. You can try again."

Upon hearing this, Chen Weiping said happily: "Mr. Li, we have conducted the experiment in Mashan. As soon as there are results, I will report to you immediately."

How could Chen Weiping not be overjoyed? Whenever Li Tianfeng encounters problems in development, he will give a quick tip and immediately have immediate results and will be able to overcome this technical problem soon. This time, Li Tianfeng said so in detail that Chen Weiping is full of confidence.

Li Tianfeng said: "Go, hurry up, our turbofan engine is waiting for rice to be put into the pot. If this ceramic-based material cannot be successfully developed, our engine will only become a second-rate engine."

Chen Weiping said loudly: "Mr. Li, I'll go to test it right away."

After saying that, Chen Weiping hurriedly and happily left Li Tianfeng's office.

Looking at Chen Weiping's back as he left, Li Tianfeng murmured, this time it must be successful, and we can't drag it down any longer. Our turbofan engine cannot be really pushed back because it does not have qualified ceramic base materials.

Donghai City.

Linhai Technology Company can only be regarded as a small and medium-sized enterprise with more than 1,000 employees, but it is different from other small and medium-sized private enterprises. Linhai Technology Company is a professional bearing company that only produces various types of bearings. Among the more than 1,000 employees, three or four hundred are technical personnel. It is rare to have such a large proportion of scientific research teams.

Linhai Technology's main products are various medium-range bearings, but they are also committed to the research and development of high-end bearings. Some bearings are even equipped with domestic aero engines. Linhai Technology has developed well in the past few years, but in the past two years, as foreign mid- and high-end bearings have entered the domestic market, Linhai Technology has a downward scent.

A middle-aged man who seems to be a middle-level manager is reporting: "Mr. Zhao, our sales this month have dropped by another two percentage points, and our profit has also dropped by three percentage points. This won't work."

Zhao Linhai waved his hand and said, "Mr. Shen, I understand, you go down!"

After the boss left his office, Zhao Linhai picked up his phone and dialed a number, "Governor Guo, how is our loan? Have you approved it?"

"What, the bank's funds are tight, no approval is approved, no!" Zhao Linhai's face changed. You know, this amount of funds is waiting to be saved.

In scientific research, Zhao Linhai has invested a lot of funds. If the company operates well, there will be no problem in investing these funds. However, in recent months, its operations have been on a downward trend. If there is no bank loan, Zhao Linhai knows that he can only support it for three or five months. The final result is that the capital chain is broken and Linhai Technology Company goes bankrupt.

Thinking of starting a business in his twenties, Zhao Linhai was unwilling to accept this company he founded after more than ten years of hard work.

Tianfeng Technology Company.

The second turboshaft engine, that is, the turboshaft e engine, has completed a series of verification and test runs, and the verification and test runs are very smooth, and the results are very perfect. Now, the engine has begun to prepare for a life test run.

The engine model certificate and production license have also been successfully released. After the life test run is completed, there will be an airworthiness certificate.

The core part of the turboshaft e engine is common to the turboshaft D engine, which saves a lot of trouble. Otherwise, the progress will be so fast. If the core engine of the turboshaft D engine is not used and it is really redesigned from the beginning, it would be nice to complete the design and shaping now, and where can the life test run be reached.

For this engine, Li Tianfeng is preparing to set the tentative lifespan of 3,000 hours. Of course, everything will have to be determined after the full life test run.

The development of the turboshaft e engine was relatively smooth, and the improvement of Wuzhi Ten was also very smooth. The improved Wuzhi Ten not only completed a series of tests and verifications, but also completed many field test flight tests. Li Tianfeng even went to the helicopter design institute and manufacturing plant several times.

Li Tianfeng was naturally invited to pass by. The entire improvement and upgrade plan for Wuzhi Ten was made by Tianfeng Technology Company. Li Tianfeng was also happy to go there and had a series of technical exchanges with Wuzhi Ten's designers and engineering technicians. Otherwise, Wuzhi Ten's progress would not be so fast.

A continental aviation group base.

The regiment commander Zheng Guanghua and his chief of staff, political commissar, deputy regiment commander were waiting at the airport, looking at the distant sky, as if waiting for something.

The Chief of Staff said: "Captain, the division commander is going to come here in person this time. Didn't you expect that the division commander should attach so much importance to it?"

Zheng Guanghua said: "This time, there are six martial arts at once, and the division commander can't take it seriously."

Speaking of Wu Zhishi, the political commissar, deputy commander and others next to him looked at the few Wu Zhishi parked in the distance, and everyone's eyes were full of brilliance.

The political commissar said: "Captain, the one who delivered our delegation this time is an improved Wuzhi Ten. I heard that the performance has been improved many times, so I am really looking forward to it!"

Zheng Guanghua said: "The superiors attach great importance to our regiment. We should give priority to the improved Martial Ten-Mart equipment. We should be familiar with these Martial Ten-Mart Ten as quickly as possible and quickly form combat power."

At this time, a captain ran over and said happily: "Captain, I heard that our regiment will have an improved Wuzhi Ten. After these Wuzhi Tens come, let me fly for the first time. How about it?"

Zheng Guanghua smiled and said, "Why, I can't hold back anymore, my skills are itchy?"

The captain grinned and said, "Captain, this is an improved Wu Zhishi. I heard that the comprehensive performance has been improved several times, strong power, advanced radar, thick armor, and powerful firepower. I really want to enjoy it."

Zheng Guanghua said: "You boy, I knew you were itchy."

The captain said, "Captain, can you do it? Please."

Zheng Guanghua smiled and said, "But it's OK, but you must not let me down after a while. The teacher and the others came here in person."

The captain was overjoyed, stood at attention, and said loudly: "Captain, don't worry, wait a moment, I will definitely make you look better."

Zheng Guanghua smiled and waved, "Go and prepare, I guess the plane is coming soon."

Yes, the anticipated plane is coming soon. Not only Zheng Guanghua, but also the chief of staff, political commissar, deputy regiment commanders, and even many battalion company commanders who have been informed, and ordinary soldiers, all looked expectant.

Many people even looked at the distance from time to time. Not long after, a few small black dots appeared in the sky in the distance, and someone immediately shouted loudly and excitedly: "Look, our Wu Zhishi is here!"

Zheng Guanghua immediately picked up the telescope and looked into the distance. These were two Z9 transport helicopters and six improved Z910 armed helicopters.
