Wang Bin and Jiang Zongliang walked towards the door while talking. At the same time, Wang Bin also learned from Jiang Zongliang that the situation in the industrial zone is very smooth. In another half a month or so, it should be almost over.

    Just as Wang Bin and his colleagues came to the door, Xifei''s car also happened to be at the door of Wang Bin''s Tiangong technology. Wang Bin and his colleagues hurried forward and said to the middle-aged man in front of Xifei, "President Xiang! Welcome! Welcome!"

    Of course, Wang Bin knows Xi Fei''s general manager. He has appeared on TV more than once. At the same time, he often appears on various online self media.

    After a few greetings, Xiang Shixiong said to Wang Bin, "Mr. Wang, your county is still good, with beautiful mountains and rivers. It''s a good place. At the same time, your Tiangong technology is also good. It''s really beyond my expectation to develop such excellent glass.

    In my impression, most of the excellent glass comes from abroad. There is still a gap between China and foreign countries in the field of materials, not to mention that Tiangong technology is still a private enterprise. It is really rare to calm down and develop new technologies and materials! "

    "Mr. Xiang, you are joking. As a private enterprise, if it does not invest in new technologies and materials, there is no future for development.

    Now those enterprises that only produce low-end products are not easy to mix. In fact, Tiangong technology is forced to be helpless. If there is no depression in the handicraft industry, in fact, it is unlikely that Tiangong technology will transform, let alone develop new products, "said Wang Bin.

    Then he said to Xiang Shixiong, "Mr. Xiang, let''s go to my office and talk!"

    Xiang Shixiong was also impolite. He smiled at Wang Bin, nodded and said, "yes, I''ll disturb you!"

    With that, Wang Bin took Xiang Shixiong to his office, while Jiang Zongliang followed Wang Bin and Xiang Shixiong and walked to Wang Bin''s office.

    Soon several people came to Wang Bin''s office. Wang Bin said to Xiang Shixiong, "President Xiang, this is the deputy general manager of Tiangong technology."

    The two shook hands, and Xiang Shixiong introduced Wang Bin to the two people who followed him.

    One of them, Fang Weiyu, is the engineer of an aircraft of Xifei, and the other, ye Guangtai, is also an aircraft engineer of their company.

    After shaking hands with each other, Wang Bin smiled and said to Xiang Shixiong, "President Xiang, you must come to our Tiangong technology this time for the special glass of Tiangong technology!"

    "Mr. Wang! Indeed, I came to your Tiangong technology this time for your glass. Of course, there are other things.

    If it''s just about glass, I don''t have to bring our engineers in person, "he said. He took out a notebook from his briefcase and put it on the tea table in front of him, but he didn''t turn on the computer, but turned his eyes to Jiang Zongliang.

    Seeing Xiang Shixiong''s eyes, Wang Bin knew why, so he nodded to Jiang Zongliang and said, "manager Jiang, go out first!"

    "OK! Mr. Wang! I''ll go out first and call me if there''s anything." Jiang Zongliang nodded and said.

    With that, Jiang Zongliang walked out of Wang Bin''s office.

    Seeing Jiang Zongliang out of the office, Xiang Shixiong turned on the computer, took out a USB flash disk from his pocket, inserted it into the computer, and then entered the password on the computer. Finally, I unlocked the computer with my fingerprint.

    After turning on the computer, Xiang Shixiong said to Wang Bin: "President Wang, the purpose of your Tiangong technology this time is naturally to buy your glass and use it in the cockpit of the fighter. However, this aircraft is not a UAV, but a real fighter. Therefore, the shape and size of the glass are like water droplets, and the requirements are very strict."

    Then he turned the computer in his hand and said to Wang Bin: "For example, the shape of this glass shield is somewhat complex, the technical difficulty coefficient is high, and during production, there must be no bubbles on the glass or a trace of dimensional error. Therefore, President Wang, please pay more attention during production. This is not ordinary glass, but fighter glass.

    The most important thing is that this fighter is capable of supersonic cruise. Once the size of the glass deviates or there are bubbles in the glass, it will affect the performance of the fighter at least, or it may fall down and destroy people. "

    After listening to Xiang Shixiong''s words, Wang Bin nodded seriously. Of course, Wang Bin, who has obtained kanxing glass technology, knows very well that this glass itself is an aerospace glass. When obtaining the technical knowledge of this glass, Wang Bin also obtained a lot of relevant knowledge in aerospace.

    Xiang Shixiong called out another data and drawing and said to Wang Bin: "this is the glass of a transport aircraft. Compared with the glass cover of the previous fighter, the production difficulty coefficient of this glass is relatively simple, but it is not much lower.

    Compared with the fighter, the glass volume of this aircraft is larger. It is said that the flight speed of the aircraft is not as fast as that of the fighter.

    However, because this aircraft needs to meet the landing capacity of the field airstrip, the possibility of this aircraft being hit by birds and other organisms has also been greatly improved. In the past few years, our aircraft has been hit by birds, resulting in the loss of aircraft and even pilots.

    Therefore, for this aircraft glass, it should be better in terms of anti-collision performance. Of course, it is best to be able to defend against the shooting of general light and heavy weapons. "

    Subsequently, Xiang Shixiong showed Wang Bin several aircraft glasses and put forward requirements, while Wang Bin listened to Xiang Shixiong''s introduction seriously.

    As Xiang Shixiong said, the requirements of these aircraft for glass are indeed very high and the coefficient of technical difficulty is large. However, with the current capacity of Tiangong technology, it can still be produced, but the speed of production will certainly not go anywhere fast.

    Soon Xiang Shixiong introduced the requirements for the glass of these fighters, and then opened another document and said to Wang Bin; "Mr. Wang, the main purpose of my coming here this time is for this project, in addition to ordering the cockpit glass from you."

    Xiang Shixiong turned the computer to Wang Bin again and said, "as you can see, this is a high-speed high-altitude UAV project. Originally, we were going to use titanium alloy or synthetic materials to manufacture the UAV fuselage, but if these materials are used, the flight performance of this UAV will be greatly affected.

    Because in terms of our design expected speed, our designed flight speed is above Mach 3, but if we fly at Mach 3 at high altitude, the temperature of the fuselage, especially the nose position, will rise sharply, and ordinary materials can''t bear it at all. Even titanium alloy will soften under the impact of high temperature and high pressure for a long time.

    For these reasons, we were going to put this project aside first, but now because of your glass, we have changed our idea to directly use your special glass to manufacture the fuselage.

    Your glass not only has high strength, but also has good data in high temperature resistance, impact resistance, pressure resistance and load resistance.

    According to our calculation, if we directly use this glass to make the fuselage, the flight speed of this UAV will be improved qualitatively.

    I think Mr. Wang, you must have a good understanding of the performance of your glass, and the maximum temperature resistance has reached more than 2100 degrees. If the engine power of this UAV is sufficient, the maximum speed can reach Mach 4, which is absolutely no problem. "
