- "How about it, Mr. Zhuang? If you also think the cost is high, then I will go back and change it again." Seeing that Zhuang Jianye didn't speak for a long time, Song Yanan couldn't help himself.
It¡¯s just that no matter what the words are, they always sound unpleasant when they come out of her mouth.
Fortunately, Zhuang Jianye knew that Song Yanan was a person who only cared about scientific research. If he hadn't been so early in Xi'an Airlines, he would not have been sitting on the bench, so he didn't care and picked up the sample of the honeycomb structure component from his desk again. After weighing it with his hands, he said: "It seems that we are not very strong in metal materials."
"My Mr. Zhuang, not only are we not strong in metal materials, we have no similar research at all, okay? Our factory's chemical milling can process one or two metal materials, but those are all from Yonghong The basic information obtained from the factory does not really belong to us at all.¡±
As he spoke, Song Yanan pointed to the honeycomb structure component in Zhuang Jianye's hand and continued: "Although the two wall panels are made of aluminum-lithium alloy, the relevant technology was given to us by the aerospace department, so that we came here for technical exchanges. The engineers in the aerospace department were incredulous. They felt that our unit, which can make carbon fiber composite materials extremely pure, could not even understand basic aluminum-based alloys. It really made people laugh for a while, and then they gave us eight words. Comments.¡±
"Those eight words?" Zhuang Jianye asked curiously.
"The strong will always be strong, the weak will weaken."
After hearing this, Zhuang Jianye was startled for a moment, and then he laughed. The evaluation of the aerospace department engineer was indeed on point. The strong ones will always be strong and the weak will weaken at Tengfei Aviation Manufacturing Corporation.
It is really extremely powerful in small gas turbine power units, carbon fiber composite materials, long-range long-endurance drones, and aerospace-specific production equipment.
But when it comes to classification details involving manned aircraft, such as flight hydraulic systems, pressurized cabin installations, and air circulation systems, the shortcomings of Ascendas Corporation's weak foundation become apparent.
The same is true for the research on materials. Starting from the very beginning of the 23rd Factory, over the years, Tengfei Aviation Manufacturing Corporation has focused almost all its resources on carbon fiber composite materials. Other material categories are involved. , without even touching it.
This has caused Tengfei Aviation Manufacturing Corporation to be seriously biased in aviation materials.
Except for carbon fiber composite materials, there are almost no good things that can be obtained. This is why Song Yanan said that the strong will always be strong and the weak will weaken.
It was clearly a tactful way to tell him that the Aluminum Honeycomb Tengfei Aviation Technology R&D Center could do it, but it was very difficult. It was impossible to see results in a month or two, and it would be more like waiting for another one or two years.
" Song Yanan can give such a tactful warning. Apart from Zhuang Jianye, there really is no one else. Even if it is her husband at home, he will go straight to the point and never mince words.
The reason for this is nothing but gratitude.
Whether it was getting her from the bench of Xihang University or having a second child beyond the target to help her shoulder the responsibility, it is no exaggeration to say that without Zhuang Jianye, there would be no Song Yanan she is today.
Because of this, Song Yanan really feels like family at Ascendas Aviation Technology R&D Center. Not only does he work with peace of mind and down-to-earth, but he also works very hard.
As for Zhuang Jianye, he has great respect for him. Even though most of the time he speaks in a tough tone and even has an invisible last-minute effect, Song Yanan can still lower his body and make some insidious reminders when it comes to matters of right and wrong.
Zhuang Jianye is such a smart person, how could he not understand the meaning of Song Yanan's lame words.
What¡¯s more, his own attainments in aviation are not bad. Naturally, he knows that although the aluminum honeycomb sandwich is made of aluminum, it is a complex component that requires complex heat treatment, sheet metal processing and prefabrication of extremely thin aluminum plates.
Although the cost is much lower than that of aramid paper based on composite materials with a honeycomb structure, the problems are the conductivity of metal, galvanic corrosion problems, large local instability, and almost zero filtration of poisonous mist, etc., which makes Aluminum honeycomb is not even the slightest bit worse than aramid paper honeycomb.
What's more important is that Tengfei Aviation Manufacturing Corporation does not have the technology to process and produce aluminum honeycombs. There are such manufacturers in China. The problem is that all kinds of coordination, negotiation, and cooperation cannot be done in a short time. Even if everything goes well and the finished product is obtained Tengfei Aviation Manufacturing Corporation also needs to explore the processing technology of such honeycomb components.
If nothing else, the metal bonding between the honeycomb sandwich and the wall panels on both sides is a big problem and takes a lot of time.
So Zhuang Jianye had a choice without Song Yanan¡¯s reminder.
What's more, compared to aluminum honeycomb, aramid paper honeycomb is the mainstream direction of honeycomb components. Since this type of technology is at the forefront of the world, it is not widely used. In more than ten years, it will be A series of high-quality carbon fiber composite materials are mature, especially the emergence of stealth composite materials.
Stealth composite materials based on aramid paper honeycomb will become an important component of stealth fighters.
As for the F-35, the upper flaps, ailerons, horizontal tail leading edge, vertical tail leading edge, and rudder all use this type of composite honeycomb structure.
Therefore, whether it is for reality or for planning for the future, the basic structure of aramid paper honeycomb cannot be abandoned. As for the cost of the improved Yun-5, Zhuang Jianye feels that although the cost is important, the cultivation of key technologies cannot be ignored.
Since it cannot be reconciled during development, then work hard to expand the market. As long as the output of the improved Y-5 increases, the high cost will also be diluted.
So Zhuang Jianye put down the honeycomb component in his hand, tapped it with his fingers, and then nodded: "We don't have enough time, so we should follow your wishes, Sister Song."
After hearing what Zhuang Jianye said, Song Yanan breathed a sigh of relief, and then asked worriedly: "Where is the Lin Gong"
"I'll go talk to Lin Gong, and you can just prepare and organize production with peace of mind. Oh, by the way, the processing technology of the components is mature, right?"
"Don't worry, the research center has been conducting research in this area since the first generation. As long as the head office gives an order, our research center can immediately create the required components." Song Yanan's words were sonorous and confident. It's like a queen reigning over the world.
Zhuang Jianye smiled and nodded: "That's good."
After that, the two chatted for a while about follow-up production issues. Song Yanan then left. Zhuang Jianye walked to the door, turned around and called Lin Guanghua when he came back.
When Lin Guanghua on the other end of the phone heard what Zhuang Jianye said, he naturally felt that it was not a good deal. However, after listening to Zhuang Jianye's reasons, he had to admit that the strong ones in Tengfei Aviation Manufacturing Corporation are always strong and the weak are weakened. In addition, It was another call from Zhuang Jianye himself. Although Lin Guanghua felt that the cost could be lowered, he still nodded and accepted it.
¡¡
A few months later, as the New Year's bell rang, the gears of time officially turned to 1987. On the day of family reunion, the north wind howled in the Guanzhong hinterland Grain City Flight Test Center attracted an uninvited guest. ¡ª¡ªThe latest improved Y-5 transport aircraft developed by Tengfei Factory has rolled off the production line.
