Chapter 416

Wu Changcheng didn't deliberately lower his voice. It came out through the empty porthole of the plane. Professor Ding heard it very clearly.

Quickly looked at each other, from each other's faces to see a touch of emotion called surprise.

They may not know about aluminum lithium alloy or aramid paper, but France's mirage 2000 fighter is full of thunder. As one of the few third-generation fighters in the United States and the Soviet Union, mirage 2000 fighter has attracted the attention of aviation circles all over the world as soon as it came out.

Among them is China.

So that in a certain period of time, China almost brought this fighter back. As a new generation of main fighter, it was a pity that the French asked too much for it, and finally it was not settled.

Wu Changcheng was one of the members of the domestic technical expert group who went to France to investigate mirage 2000. Because of this, when it comes to understanding French fighters, Wu Changcheng is an authority, so it's not surprising that Ding laixiang and others were surprised.

"Lao Wu, are you sure the material of the improved yun-5 is the same as that of the French Mirage 2000?" Researcher Qian, who is standing behind Ding laixiang, is an acute man. After a short surprise, he immediately asks Wu Changcheng in the cabin.

Wu Changcheng poked his head out of a porthole: "listen to Xiao Lin's narration, it's similar to what I saw in France last year. Of course, I don't know much about it. After all, this technology belongs to the most cutting-edge field in France. They only used some of it on the aileron of mirage 2000, preparing to realize large-scale application before the mid-1990s."

As soon as this remark came out, researcher Qian frowned deeply. Even France, whose aviation technology far exceeds China's, did not put this technology into large-scale use, but only used it on a small scale on a small bearing structure such as aileron.

The more you think about it, the more you think about it, the more you think about it.

So he wanted to say a few words of criticism, but before he spoke, Lin Guanghua leaned out of another porthole and said, "the French are still too conservative. The F-15 and F-18 of the United States have applied similar materials to almost all control surfaces.

However, our research on Tengfei Airlines has found that honeycomb structure airframe may not be suitable for high overload, but it is competent enough for small general-purpose aircraft with smooth flight. "

Then he patted the outer skin with his hand and continued with a thumping sound: "all the aluminum lithium alloy sheets on both sides of the inner and outer sides have been finely processed by chemical milling process, and the thickness is controlled within 0.025mm, and they are all formed at one time. Then they are divided into two large-scale finished parts, which are made into two fixed assembly modules by bonding and thermal curing furnace, Then, it will be merged together to become the core main cabin of the improved yun-5

After a pause, Lin Guanghua quickly stepped out of the cabin and his voice became louder and louder: "I dare not say that these technologies are groundbreaking, but they are definitely very forward-looking in China. Let alone do a comprehensive test for honeycomb structure, I think it is also a breakthrough in the domestic aviation field. You know, similar materials have been widely used in Europe and America When it comes to applications, why can't we?

Even if the final test of our improved yun-5 proves to be a failed attempt, we have at least worked hard. After all, aviation technology is a very practical subject. Although our Tengfei aviation manufacturing company is small, we dare to bear the necessary material sacrifice for the development of aviation technology. "

Lin Guang's Chinese language is very fast, from the manufacturing technology applied by Tengfei Aviation Manufacturing Corporation to the explanation of the whole honeycomb structure, and finally to the sincere expression that he dares to sacrifice for scientific research.

Say that call a righteousness awe inspiring, match that some tiny twinkle of vision, but like will go to the battlefield of the warrior, impassioned in a mess.

It was as if Lin Guanghua and Tengfei Aviation Manufacturing Corporation were going to suffer a lot. Knowing that they could not do it, they were almost ready to devote themselves to scientific research.

However, in fact, Lin Guanghua was annoyed by Wu Changcheng and a group of old professors. You say to explain advanced materials to them, they are suspicious; explain the advanced manufacturing technology of the head office, the tone of suspicion is even greater. In this case, Lin Guanghua simply doesn't want to waste saliva, instead, he simply hangs the plane on the static test bench and speaks with facts.

Ding laixiang, Wu Changcheng and other people didn't know Lin Guanghua's evil mind learned from Zhuang Jianye. They looked at each other and then bowed their heads to discuss. They thought Lin Guanghua's words were quite reasonable. No matter what the aircraft type was, the practice of new materials and new technology has always been the core element of the continuous development of aviation technology.

So instead of talking nonsense, they directly let the lifting equipment transfer the improved yun-5 to the static test bench, and then the officers and men of the test bench began to add counterweight lead blocks on and off the aircraft fuselage according to the technical samples obtained in advance.

……

In Tengfei Aviation Manufacturing Corporation, Zhuang Jianye accompanied two old men, one tall and one short, to walk out of the headquarters office building in Huancheng. As soon as they stopped walking, one of them, a stout old man in military uniform, looked back at Zhuang Jianye: "I saw that your new products are really good. They are very helpful to the logistics of the army. I will report to the higher authorities when I go back."Then he looked at the tall and thin old man beside him and asked with a smile, "how's it going? Would Professor Hong like to join us? "

The thin and tall old man is the leader of the health department. Professor Hong Xiaosong, who once wrote the inscription "keep improving" to the medical department of Tengfei factory, listened to the words of the commander of the short and fat army, Hong Xiaosong shook his head with a smile: "good things are good, but we don't have much demand for such things. It's better to improve the medical institutions at the county level if we have the money to purchase them."

After listening to Hong Xiaosong's words, the chubby army chief could not help but smile and nodded in agreement: "it's true. Seriously, if the medical support equipment of the army had not been improved for so many years, I would not have spent so much money."

The voice both fell and looked up at Zhuang Jianye: "Xiaozhuang, do you want to tell me the truth, those things that show us are really the application of the latest aerospace technology?"

"It's true." Zhuang Jianye quickly patted his chest and assured: "you two have just seen that all the plates are imported aviation materials from Germany and France. They not only keep warm, dry and sound insulation, but also have part of the functions of supercharged cabin. Only aerospace technology can have such an effect."

The stout chief of the army nodded after hearing this, then chatted with Zhuang Jianye, and then got on the bus with Hong Xiaosong and left.

Zhuang Jianye, who was about to finish a big business, was in a good mood. Until the car disappeared for a long time, he put down his hand to wave goodbye and looked at his watch. It was almost 6 p.m., so he stretched out and was ready to go home from work. But before he turned over and went upstairs to pick up his things, assistant Xiao Zheng ran down in a hurry: "Mr. Zhuang, Lin Gong phone."

Just in a word, when Zhuang Jianye came home from work, he immediately forgot about it, turned over and rushed upstairs, pushed the door to his office, picked up the phone on the desk, but before he could speak, Lin Guanghua over there cried out: "Lao Zhuang, the head of the army asked us to change the plane..."
