"If you also think the cost is high, then I'll go back and change it again. Seeing that Zhuang Jianye didn't speak for a long time, Song Yanan was a little breathless.

It's just that no matter what the words are, they always feel very bad when they come out of her mouth.

Fortunately, Zhuang Jianye knew that Song Yanan was a person who only cared about scientific research, and if it weren't for this, he wouldn't have sat on the cold bench when he was in Xihang in the early years, so he didn't care, but picked up the sample of the honeycomb structure component from the desk again, checked it with his hand, and then said: "It seems that we are not very strong in metal materials." ”

"My Mr. Zhuang, we are not strong in metal materials, there is no similar research at all, don't look at the chemical milling of our factory can do one or two metal material processing, but that is the basic information from the Yonghong factory, and there is no real one of our own. ”

Saying that, Song Yanan pointed to the honeycomb structural parts in Zhuang Jianye's hand and continued: "Don't look at the two siding panels are made of aluminum-lithium alloy, but the relevant technology is given to us by the aerospace department, so that the engineers of the aerospace department who came to do technical exchanges are incredible, and feel that we are a unit that can make carbon fiber composite materials pure and incomparable, and they can't even understand the basic aluminum-based alloy, which really makes people laugh for a while, and then gave us an eight-word comment." ”

"Those eight words?" Zhuang Jianye asked curiously.

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

Hearing this, Zhuang Jianye was stunned for a moment, and then laughed, the evaluation of the aerospace department engineer did hit the point, Tengfei Aviation Manufacturing Corporation is really strong and strong, and weak and weak.

In small gas turbine power units, carbon fiber composite materials, long-range long-endurance drones, aerospace special production equipment, it is really extremely powerful.

However, in terms of classification details such as flight hydraulic system, pressurized cabin device, air circulation system, etc., which involve manned aircraft, the disadvantages of the thin foundation of Tengfei head office are revealed.

The same is true for the research of materials, starting from the first 23 branches, after so many years, Tengfei Aviation Manufacturing Corporation has almost piled all the resources on the materials on the carbon fiber composite materials, and other material categories are almost not involved, and they have not even touched it.

This has caused Ascendas Aviation Manufacturing Corporation to be seriously biased in aviation materials.

In addition to carbon fiber composite materials, there are almost no good things that can be used, which is why Song Yanan said that the strong are always strong, and the weak are weak.

It is clear that he told him euphemistically that the aluminum honeycomb take-off aviation technology research and development center can do it, but it is very difficult, it is impossible to see results in one or two months, and it is almost the same to wait for another one or two years.

can make Song Yanan so euphemistically admonished, except for Zhuang Jianye, there is really no second one, even if it is her husband at home, it is also a time when she goes straight and never beats around the bush.

The reason why this is so, there is no other than the word gratitude.

Whether it was from the cold bench of Xihang University, or the over-the-target birth of a second child to help her shoulder the responsibility, it is no exaggeration to say that if there was no Zhuang Jianye, there would be no Song Yanan she is today.

Because of this, Song Yanan is really like a family in Tengfei Aviation Technology R&D Center, not only working very reassuringly, down-to-earth, but also working very hard.

As for the respect for Zhuang Jianye, even if he speaks hard most of the time, and even has an invisible mending effect, but in matters of right and wrong, Song Yanan can still lower his body and make some side knock reminders.

Zhuang Jianye is such a smart person, where can he not hear the meaning of Song Yanan's lame words.

What's more, his own attainments in aviation are not bad, and it is not clear that although the aluminum honeycomb sandwich is made of aluminum, it is an extremely light and thin aluminum plate that can only be made of complex parts after complex heat treatment, sheet metal processing and prefabrication.

Although the cost is much lower than that of aramid paper based on composite materials, the problems are the conductivity of the metal, the problem of galvanic corrosion, large local instability, almost zero filtration of toxic fog and other defects, which makes the aluminum honeycomb not a little worse than the aramid paper honeycomb.

More importantly, 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 done in a moment and a half, even if everything goes smoothly to get the finished product, Tengfei Aviation Manufacturing Corporation still has to explore the processing technology of such honeycomb components.

Not to mention anything else, the metal gluing between the honeycomb sandwich and the wall panels on both sides is a big problem, and it takes a lot of time.

So without Song Yanan's reminder, 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 of the world, the application is not very wide, and so on for more than ten years, a series of high-quality carbon fiber composite materials mature, especially the emergence of stealth composite materials.

Stealth composites based on aramid paper honeycomb will become an important component on stealth fighters.

As far as the F-35 is concerned, the upper flaps, ailerons, flat tail leading edge, vertical tail leading edge, and rudder all use this kind of composite honeycomb structure.

Therefore, whether it is for the reality or the layout of the future, the basic architecture of aramid paper honeycomb can not be abandoned, as for the cost of pushing up the improved Yun 5, Zhuang Jianye feels that the cost is important, but the cultivation of key technologies can not be ignored.

Since it cannot be reconciled in the research and development, then efforts should be made to expand the market, as long as the output of the improved Yun-5 goes up, the high cost will also be diluted.

So Zhuang Jianye put down the honeycomb component in his hand, and then tapped it with his fingers, and then nodded: "We don't have enough time, let's do it according to your wishes, Sister Song." ”

Hearing Zhuang Jianye's words, Song Yanan breathed a sigh of relief, and immediately asked worriedly: "Where is the forest worker ......?"

"I'll go and say that you're ready to organize production with peace of mind, oh, by the way, the processing technology of the components is mature, right?"

"Don't worry, since the first generation, the research center has not stopped researching in this area, as long as the head office gives an order, our research center can immediately manufacture the required parts. Song Yanan's words were sonorous and powerful, and he was as confident as the queen ruling the world.

Zhuang Jianye hurriedly nodded: "That's good." ”

After that, the two chatted for a while about follow-up production problems, Song Yanan left, Zhuang Jianye sent it to the door, turned around and called Lin Guanghua when he came back.

Lin Guanghua on the other end of the phone naturally felt that it was not cost-effective when he heard what Zhuang Jianye said, but after listening to Zhuang Jianye's reasons, he also had to admit the reality that the strong of Tengfei Aviation Manufacturing Corporation are always strong and the weak are weak, plus it was Zhuang Jianye who called in person, although Lin Guanghua felt that the cost could be pressed down a little more, but he still nodded and accepted.

......

A few months later, as the New Year's bell rang, the gears of time officially turned to 1987, just in the days of family reunion, the north wind howling in the hinterland of Guanzhong Grain City Flight Test Center attracted an uninvited guest - Tengfei Factory's newly developed improved Y-5 transport aircraft.
