Chapter 413

"How about it, Mr. Zhuang? If you think the cost is high, I'll go back and make a change. " Seeing that Zhuang Jianye didn't speak for a long time, song Yanan was a little upset.

It's just that no matter what it is, it always makes people feel bad when it comes out of her mouth.

Fortunately, Zhuang Jianye knew that song Yanan only cared about scientific research. If he hadn't, he would not have been on the bench when he was at Western Airlines in his early years, so he didn't care. Instead, he picked up the sample of honeycomb structure component from his desk and weighed it with his hand. Then he said, "it seems that we are not very strong in metal materials."

"Mr. Zhuang, we are not strong in metal materials. There is no similar research at all. Although our chemical milling can process one or two metal materials, it's all the basic information from Yonghong factory. We really don't have our own."

Then song Ya Nan pointed to the honeycomb structure part in Zhuang Jianye's hand and continued: "although the two panels are made of aluminum lithium alloy, the relevant technology is given to us by the Aerospace Department, so that the engineers of the Aerospace Department who came to do the technical exchange are incredible. They think that as a unit that can make carbon fiber composite materials pure and incomparable, we can't even make basic materials "I can't understand the aluminum base alloy. It's really funny for a while, and then I gave us eight words of comments."

"Those eight words?" Zhuang Jianye asked curiously.

"The strong are always strong, and the weak are weak."

After hearing this, Zhuang Jianye was stunned for a moment and immediately laughed. The evaluation of the engineer from the aerospace department really got to the point. Tengfei aviation manufacturing corporation is really strong and weak.

In the small gas turbine power plant, carbon fiber composite materials, long-range UAV, aerospace special production equipment, it is really very powerful.

But in the classification details of manned aircraft, such as flight hydraulic system, pressurized cabin device, air circulation system, etc., the disadvantage of thin foundation of Tengfei head office appears.

The same is true for the research on materials. Starting from the first 23 branch factory, over the years, Tengfei aviation manufacturing corporation has piled all the resources on carbon fiber composite materials. Other materials, let alone other categories, have not even touched.

This has caused a serious deviation of Tengfei Aviation Manufacturing Corporation in aviation materials.

In addition to carbon fiber composite materials, there are almost no good things to hold. This is why song Yanan said that the strong are always strong and the weak are weak.

Clearly, it is a euphemistic way to tell this leader that the aluminum honeycomb take-off aviation technology R & D center can do it, but it is very difficult. It is impossible to achieve results in one or two months, and it is almost the same to wait another one or two years.

To make song Yanan so euphemistic admonishment, there is really no other one except Zhuang Jianye. Even her husband is straightforward and never beat around the bush.

The reason is that there is no other but gratitude.

Whether it's from the bench of Xihang University, or the second child of super target student who helps her shoulder the responsibility, it's no exaggeration to say that without Zhuang Jianye, there would be no song Yanan who she is today.

Because of this, song Yanan is really at home in the R & D center of take-off aviation technology. He not only works at ease, but also works hard.

As for the respect for Zhuang Jianye, even though most of the time his speech is tough, and even has the invisible effect of mending the sword, song Yanan can still lower his figure and make some insinuations when it comes to big right and big wrong.

Zhuang Jianye is such a smart man that he can't hear the meaning of song Yanan's poor words.

What's more, he has no bad attainments in aviation. Naturally, he knows that although aluminum honeycomb sandwich is made of aluminum, it is a very thin aluminum plate, which can be made into a complex part only after complex heat treatment, sheet metal processing and prefabrication.

Although the cost is much lower than that of aramid paper honeycomb structure based on composite materials, the problems are metal conductivity, electrochemical corrosion, large local instability, almost zero filtration of toxic fog and other defects, which make aluminum honeycomb worse than aramid paper honeycomb.

What's more, Tengfei aviation manufacturing corporation does not have the technology to process and produce aluminum honeycomb. There are such manufacturers in China. The problem is that all kinds of coordination, negotiation and cooperation can not be completed in a short time. Even if everything goes well, Tengfei Aviation Manufacturing Corporation will have to explore the processing technology of such honeycomb components.

Among other things, the metal bonding between honeycomb sandwich and two side panels is a big problem, and it takes a lot of time.

So without song Yanan's warning, Zhuang Jianye has a choice.

What's more, compared with aluminum honeycomb, aramid paper honeycomb is the mainstream direction of honeycomb components. Because this kind of technology is at the forefront in the world, and its application is not very extensive, a series of high-quality carbon fiber composites will be mature in more than ten years, especially the emergence of hidden composites.

The stealth composites based on aramid paper honeycomb will become an important component of stealth fighter.

For the F-35, the upper flaps, ailerons, flat tail leading edge, vertical tail leading edge and rudder all use this kind of composite honeycomb structure.Therefore, no matter for the reality or for the future layout, the basic structure of aramid paper honeycomb can not be abandoned. As for the cost of the improved yun5, Zhuang Jianye thinks that the cost is important, but the cultivation of key technologies can not be ignored. Since

can not be reconciled in the process of development, we should strive to expand the market. As long as the output of the improved transport 5 goes up, the high cost will also be diluted.

So Zhuang Jianye put down the honeycomb module in his hand, and then knocked it with his fingers. Then he nodded: "we don't have enough time. We'd better follow elder sister song's advice."

After listening to Zhuang Jianye's words, song Yanan was relieved and immediately asked anxiously, "where are the forest workers..."

"I'll go to the forest workers' side, and you'll just be relieved to prepare and organize production. Oh, by the way, the processing technology of components is mature, right?"

"Don't worry, since the first generation, the research center has not stopped the research in this field. As long as the head office gives an order, our research center will be able to produce the required parts immediately." Song Yanan's words are sonorous and powerful, and he is as confident as the queen.

Zhuang Jianye nodded with a smile: "that's good."

After that, the two talked about the problems in the follow-up production. Song Yanan left. Zhuang Jianye sent him to the door, turned around and called Lin Guanghua.

Lin Guanghua on the other end of the line naturally felt that it was not cost-effective when he heard what Zhuang Jianye had said. However, after listening to Zhuang Jianye's reasons, he had to admit the reality that the strong of Tengfei aviation manufacturing corporation are always strong and the weak are weak. In addition, it was Zhuang Jianye who called in person. Although Lin Guanghua felt that the cost could be further reduced, he still nodded to accept it It's too late.

……

A few months later, with the ringing of the new year's bell, the gear of time officially turned to 1987. On the day of family reunion, the flying test center of grain market in the hinterland of Guanzhong attracted an uninvited guest, the newly developed improved yun-5 transport plane of Tengfei factory.
