    Wu Changcheng did not deliberately lower his voice, and it was transmitted through the hollow airplane window. Professor Ding and others outside heard it very clearly.

    They glanced at each other quickly and saw a look of surprise on each other's faces.

    They may not know about aluminum-lithium alloys or aramid paper, but the French Mirage 2000 fighter jet is well known. As one of the few third-generation fighter jets from the United States and the Soviet Union, the Mirage 2000 fighter jet has aroused the attention of the aviation circles of various countries as soon as it came out.  Pay attention to.

    ??Including China.

    So much so that for a certain period of time, China almost brought this fighter back as the main fighter of the new generation, but it was a pity that the French asked for too high a price, and finally nothing happened.

    Wu Changcheng was one of the members of the domestic technical expert group that went to France to inspect the Mirage 2000 fighter jets. Because of this, Wu Changcheng can be said to be the authority when it comes to understanding French fighter jets, so it is not surprising that Ding Laixiang and others were surprised.  .

    "Old Wu, are you sure that the materials of the improved Y-5 are the same as those on the French Mirage 2000 fighter?" Researcher Qian standing behind Ding Laixiang was impatient. After a brief surprise, he immediately asked Wu Changcheng loudly in the cabin.  .

    Wu Changcheng poked his head out of a porthole: "Listening to Xiao Lin's description, it is somewhat similar to what I saw in France last year. Of course, I don't know much about the details. After all, this technology is also the most cutting-edge field in France, and they also  Some are only used on the ailerons of the Mirage 2000 and are ready for large-scale application before the mid-1990s."

    As soon as these words came out, the researcher Qian who asked the question frowned deeply. Even France, whose aviation technology far surpasses China, has not put this technology into large-scale use. It is only used on a small scale on small load-bearing structures such as ailerons.  .

    The Ascendas Aviation Manufacturing Corporation, which has no experience in producing manned aircraft, has enlarged it to the entire aircraft body and eliminated the annular load-bearing structure. The more I think about it, the more I feel that the Ascendas Aviation Manufacturing Corporation has taken this aspect for granted.

    So he wanted to say a few words of criticism, but before he could say anything, Lin Guanghua stuck his head out of another porthole and said first: "The French are still too conservative. The American F-15, F-  18 Similar materials have been applied to almost all control surfaces.

    ?????????????????????????????????????????????????????????????????????OUTOUT THE AIRCRAFT  "

    As he spoke, he patted the outer skin with his hand and continued with a thumping sound: "The aluminum-lithium alloy plates on the inner and outer sides are all finely processed using the chemical milling process, and the thickness is controlled within the range of 0.025mm.  It is all molded at one time; then it is divided into two large finished parts, the upper and lower parts, which are made into two fixed assembly modules using glue and a thermal curing oven, and then merged together to become the core main cabin section of the improved Y-5."

    After a pause, Lin Guanghua quickly walked out of the cabin, his voice getting louder and louder: "I dare not say that these series of technologies are groundbreaking, but they are definitely very forward-looking in China. If nothing else,  Just to conduct a comprehensive test for the honeycomb structure, I think it is also a breakthrough in the domestic aviation field. We must know that similar materials have been used in Europe and the United States, why can't we?

    Even if the final test of our improved Y-5 proves to be a failed attempt, at least we have worked hard and fought hard. Aviation technology is a highly practical subject after all. Although our Tengfei Aviation Manufacturing Company is not large, for the development of aviation technology, we  The necessary material sacrifices can still be endured.  "

    Lin Guanghua spoke very fast, from the manufacturing technology applied by Ascendas Aviation Manufacturing Corporation, to the explanation of the entire honeycomb structure, to finally his heartfelt words of sincere expression of his willingness to sacrifice for scientific research.

    "It was said with awe and righteousness, and with the slightly flickering eyes, he was as impassioned as a warrior about to go to the battlefield.

    "It was as if Lin Guanghua and Tengfei Aviation Manufacturing Corporation were going to suffer a lot. They knew they couldn't do anything but did it, and they almost sacrificed their lives for scientific research immediately.

    However, in fact, Lin Guanghua was annoyed by Wu Changcheng and a group of old professors. If you told them to explain advanced materials to them, they would be more skeptical; if you explained the company's current advanced manufacturing process, the tone of suspicion would be even greater. Since  In this case, Lin Guanghua simply didn't want to waste his saliva, so he simply hoisted the aircraft to the static test stand and let the facts speak for themselves.

    Ding Laixiang, Wu Changcheng and others didn't know that Lin Guanghua had learned from Zhuang Jianye. They looked at each other, then lowered their heads to discuss, and felt that Lin Guanghua's words were quite reasonable.  The practice of craftsmanship has always been a core element of the continuous development of the aviation technology field.

    SoNo need to talk nonsense, just let the hoisting equipment transfer the improved Y-5 to the static test bench. Then the officers and soldiers on the test bench began to add lead weights to the upper and lower parts of the aircraft fuselage according to the technical samples obtained in advance.

    ¡­¡­

    Ascendas Aviation Manufacturing Corporation, Zhuang Jianye accompanied two old men, one tall and one short, walking out of the headquarters office building in Huancheng. When they were about to reach the two old men, they stopped in their tracks. One of them, a short and fat old man in military uniform, turned around.  Looking at Zhuang Jianye: "I just saw that your new product is really good. It is very helpful to the army's logistics. I will report it to my superiors when I get back."

    As he said that, he looked at the tall and thin old man next to him and asked with a smile: "How is it? Professor Hong, do you want to come with us?"

    The tall and thin old man was the leader of the health department. Professor Hong Xiaosong, who once wrote the inscription "Striving for Excellence" to the medical department of Tengfei Factory, listened to the words of the short and fat leader of the army. Hong Xiaosong smiled and shook his head: "The things are good, but we  There is not much demand for this kind of thing, and if we have the money to purchase it, it would be more practical to improve county-level medical institutions.¡±

    After listening to Hong Xiaosong's words, the pudgy troop leader couldn't help but smile. He nodded in agreement: "That's true. To be honest, if the military's medical support equipment hadn't improved over the years, I wouldn't have had such a big headache.  Money.¡±

    After he finished speaking, he looked up at Zhuang Jianye: "Xiao Zhuang, do you have to tell me the truth? Are the things you showed us really using the latest aerospace technology?"

    "It's absolutely true." Zhuang Jianye hurriedly patted his chest and assured: "You two have just seen that the boards and other materials are all aviation materials imported from Germany and France. They are not only warm, dry, soundproof, and most importantly, they are also pressurized.  Some of the functions of the cabin can only be achieved by aerospace technology."

    The pudgy troop leader nodded after hearing this, then chatted with Zhuang Jianye for a few words, then got into the car with Hong Xiaosong and left.

    Zhuang Jianye, who was about to finish a big business, was in a good mood. It wasn't until the car disappeared for a long time that he put down his goodbye hand and looked at his watch. It was almost six o'clock in the afternoon, so he stretched out and was about to go home from work, but  Before he could go upstairs to pack his things, assistant Xiao Zheng hurried down: "Mr. Zhuang, Lin Gong's phone number."

    Just one sentence, why Zhuang Jianye came home from work, he immediately forgot about it, turned over and rushed upstairs, opened the door to his office, picked up the phone on the table, but before he could say anything, Lin Guanghua over there heard  He was the first to shout: "Lao Zhuang, the leader of the army asked us to modify the plane"
