After the basic cooling, the door of the sintering test equipment opened, and Chen Weiping personally took out the sintered samples from the equipment.

The afterglow dissipated, Li Tianfeng wore white gloves, took this sample and looked at it in person, and even took a magnifying glass, at this time Li Tianfeng, a hanging heart was far from being put down, and after taking a closer look, Li Tianfeng was basically a little relieved.

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

In Chen Weiping's view, this is the result of countless experiments in the past few months, and Chen Weiping is most concerned about this sample in his heart.

After looking at the sample for a long time, and even taking a magnifying glass to look at it carefully, Chen Weipin said: "Mr. Li, from the appearance, this sample is very good." ”

Li Tianfeng nodded, "I also think that at least there is no problem with the appearance, but how about the performance, it has to go through detailed testing and performance analysis." ”

Chen Weiping immediately said: "Xiao Liu, come over and immediately conduct a detailed inspection of this sample!" ”

A young white coat came over and walked away with the sample, apparently performing a performance test as required.

Li Tianfeng knew that the test results would take a long time to come out, and Li Tianfeng was not ready to wait here, so Li Tianfeng got up and said, "Chen Gong, tell me immediately if you have the test results." ”

Chen Weiping immediately said: "Mr. Li, don't worry, I will send the results to your office as soon as they come out." ”

Li Tianfeng nodded, out of the materials engineering center, in Li Tianfeng's heart, this ceramic matrix composite material is very important.

This one is a turbofan engine. There are several important key factors for the success of the development, among which the high-quality aerospace bearings mentioned earlier are a factor, in addition, there are several new materials that are also crucial, such as the ceramic-based material just now.

As far as the design of the turbofan engine is concerned, Li Tianfeng's technical level is there. And there is a technology that is decades ahead of this era, and the development direction of future aero engines, the fifth, sixth, and even seventh generation aero engines are clearly known.

A generation of materials, a generation of new aero engines, the upgrading of aero engines is related to new materials, without new materials, Li Tianfeng can not develop advanced aero engines. It's hard for a good woman to cook without rice!

In the afternoon.

Chen Weiping really sent the test results over in person, and looking at Chen Weiping's face, it seemed that the results were not very satisfactory.

Sure enough, Li Tianfeng took the test results and found that there were several indicators that were unqualified, and there was one key indicator, although it was not far from qualified, it was still unqualified.

Read the test report. Li Tianfeng said: "Chen Gong, it's still unqualified!" ”

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

Li Tianfeng put down the test results and said in his heart, sure enough, this ceramic-based material is really difficult to develop, and it is only in the test stage. After so many trial and error, I still haven't been able to achieve full qualification.

After thinking about it, Li Tianfeng said: "Chen Gong, improve the ratio like this, and increase the No. 3 substance by 0.5%. Correspondingly, the No. 7 substance is reduced by 0.5%, and the sintering temperature is increased by 10 degrees, and the time is increased by 15 minutes. ”

Hearing this, Chen Weiping said happily: "Mr. Li, we have launched a test in Mashan, and I will report to you as soon as there is a result." ”

Whenever Chen Weiping is not happy, whenever there is a problem in the development, Li Tianfeng gives a little guidance, and it will immediately have an immediate effect, and he will soon be able to solve this technical problem.

Li Tianfeng said: "Go, hurry up, our turbofan engine is waiting for rice to cook, if this ceramic-based material cannot be successfully developed, our engine can only be reduced to a second-rate engine." ”

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

After speaking, Chen Weiping hurriedly walked out of Li Tianfeng's office happily.

Looking at the back of Chen Weiping leaving, Li Tianfeng muttered, this time it must be successful, it can't be delayed any longer, our turbofan engine can't really be pushed over again because there is no qualified ceramic-based material.

Tokai City.

Linhai technology company can only be regarded as a small and medium-sized enterprise, more than 1,000 employees, but different from other small and medium-sized private enterprises, Linhai technology company is a professional bearing company, only produces all kinds of bearings, and more than 1,000 employees, there are three or four hundred people are technical personnel, such a large proportion of scientific research team, which is rare.

Linhai science and technology main products are all kinds of mid-range bearings, but also committed to the research and development of high-end bearings, and even some kinds of bearings are also installed on the domestic aero engine, a few years ago Linhai science and technology development is good, but in the past two years, with the foreign high-end bearings into the domestic market, Linhai technology has a downhill taste.

A middle-aged man who seems to be a middle-level manager is reporting: "Mr. Zhao, our sales have dropped by two percentage points this month, and our profits have also dropped by three percentage points. ”

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

After the boss came out of his office, Zhao Linhai picked up his phone and dialed a number, "President Guo, how is our loan?" Approved? ”

"What, the bank is short of funds, and there is no approval for it, it won't be!" Zhao Linhai's face changed, you know, this fund is waiting for help.

In scientific research, Zhao Linhai has invested a lot of money, if the company is doing well, there is no problem in investing these funds, but in the past few months, the operation has been going downhill, and if there is no bank loan, Zhao Linhai knows that he can only support three or five months, and the final result is that the capital chain is broken, and Linhai Technology Company is bankrupt.

Thinking that he started his business in his twenties, after more than ten years of hard work, he created this company single-handedly, Zhao Linhai was unwilling.

Tianfeng Technology Company.

The second turboshaft engine, the turboshaft E engine, has completed a series of validation tests, and the validation tests have been very smooth, the results have been perfect, and the engine is now ready for life testing.

The type certificate of the engine and the production license have also been smoothly down, and there will be an airworthiness certificate only after the completion of the life test.

The turboshaft E engine core part is common to the turboshaft D engine, which will save a lot of things, otherwise, where is the progress so fast, if you don't use the turboshaft D engine core machine, if you really redesign it from scratch, it is good to complete the design now, where can you go to the life test.

For this engine, Li Tianfeng is ready to tentatively set the life of the first turn is 3000 hours, of course, a qiē can only be determined when the life test is fully completed.

The development of the turboshaft E engine is relatively smooth, and the improvement work of the Wuzhi-10 is also very smooth, and the improved Wuzhi-10 has not only completed a series of tests and verifications, but also completed a lot of outfield flight tests, and Li Tianfeng has gone to the helicopter design institute and manufacturing plant several times.

Li Tianfeng was naturally invited to pass, the entire improvement and upgrading plan of Wuzhi Shi was made by Tianfeng Technology Company, Li Tianfeng was also happy to go over, and Wu Zhi Shi's designers, engineering and technical personnel conducted a series of technical exchanges, otherwise, where is the progress of Wu Zhi Shi so fast.

A base of an army aviation regiment.

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

The chief of staff said: "Regiment commander, this time the division commander is going to come over in person, didn't you think that the division commander attaches so much importance to it?" ”

Zheng Guanghua said: "This time it's a one-time six-time martial arts ten, and the division commander can't pay attention to it." ”

Speaking of Wu Zhi Shi, the political commissar and deputy head next to him looked at the several Wu Zhi Shi parked in the distance, and everyone's eyes were full of glitter.

One of the political commissars said: "Regiment commander, this time the one delivered to our regiment is the improved Wuzhi Shi, I heard that the performance has been improved many times, I am really looking forward to it!" ”

Zheng Guanghua said: "The superiors attach great importance to our regiment, and the improved Wuzhi Ten give priority to equipping us, so we can familiarize ourselves with these Wuzhi Ten as quickly as possible and quickly form combat effectiveness." ”

At this time, a captain ran over and said happily: "Regiment commander, I heard that our regiment will have an improved Wuzhi Shi, wait a minute, let me fly for the first time after these Wuzhi Shi, how about it?" ”

Zheng Guanghua smiled: "What's the matter, I can't hold it back, it's itchy?" ”

The captain grinned, "Regiment Commander, this is an improved Wuzhi Shi, I heard that the comprehensive performance has been improved several times, strong power, advanced radar, thick armor, and powerful firepower, I really want to have a good time." ”

Zheng Guanghua said: "You kid, I know that you are itchy." ”

The captain said, "Commander, it's okay, please." ”

Zheng Guanghua smiled and said: "But you can, but wait a minute, you must not drop the chain for me, the teacher and they came in person." ”

The captain was overjoyed, stood upright, and said loudly: "Regiment commander, don't worry, I will definitely give you a face later." ”

Zheng Guanghua smiled and waved his hand: "Let's go and prepare, I estimate that the plane will come soon." ”

Yes, the expected plane is coming soon, not only Zheng Guanghua, but also the chief of staff, political commissar, deputy regiment commander, and even many battalion and company commanders who have heard the news, ordinary soldiers, everyone is looking forward to it.

Even, many people also looked into the distance from time to time, and not long after, a few small black spots appeared in the sky in the distance, and immediately someone shouted loudly and excitedly: "Look, our Wuzhi Ten is coming!" ”

Zheng Guanghua immediately picked up the binoculars and looked into the distance, these were two Zhizhi-9 transport helicopters and six improved Wuzhi-10 armed helicopters.
