Chaoshen Technology Trading Mall Chapter 69

　　 After hearing what Xiang Shixiong said, Wang Bin thought about the performance of his glass.

Indeed, as Xiang Shixiong said, if the fuselage of this drone really uses this glass, as long as the engine is strong, it is not impossible to reach the speed of Mach four, but the temperature of the aircraft fuselage at this time , Will also rise to the limit that this glass can withstand.

And this speed can only be achieved at an altitude of more than 10,000 meters. If the altitude of the drone is less than 10,000 meters, then flying at this speed, only the temperature generated by the friction between the glass and the air will be Exceed the temperature limit that their glass can withstand.

　　 Of course, if the speed is below Mach 4, the high temperature resistance and other properties of this glass can still be eaten away. Of course, if the body is coated with heat insulation paint, it is not impossible to go to Mach 4 at low altitude.

　　 So Wang Bin said: "It is true that if our glass is used as the body, the speed of Mach 4 at high altitude is not a problem. Even at low altitude, the speed of Mach 3 can still be tolerated."

"The specific data of our Xifei scientific research personnel has been calculated, and it is absolutely not a problem. The biggest question now is whether or not Tiangong Technology is capable of using this glass to manufacture the body of this drone. .

After all, the fuselage of this drone is not pieced together using flat glass. Take the wing of this drone as an example. The wing is an integrated wing, which must be completed at one time during the production process. At the same time, there should be no deformation at all. Otherwise, the UAV is very easy to lose control during the flight, especially during the high-speed flight.

In addition, there is also the segmented part of the fuselage, which is also very technically difficult. The drone fuselage is required to be segmented. There are no thorns on the surface and no protrusions. This can reach a speed of 4 Mach. A little glitch on the aircraft may cause problems with this aircraft.

　　The last part is the nose and tail part, and there can be no errors,..."

With the introduction of Xiang Shixiong and these two engineers, Wang Bin has a basic understanding of the technical difficulties of manufacturing the fuselage and wing parts of this drone. At the same time, he is also thinking about how to do it. Solve these technical difficulties.

After Xiang Shixiong and the others introduced all the technical difficulties of this drone fuselage, Wang Bin fell into thinking. The manufacture of this drone fuselage is a very important issue for Wang Bin or their Tiangong Technology. Big challenge.

　　 First of all, the thickness of the fuselage glass. According to their previous introduction, Wang Bin believes that the thickness of the fuselage glass of this drone should not be too low, at least not less than one millimeter.

Otherwise, when the aircraft is flying at high speed, the heat generated will definitely make the internal parts of the drone overwhelmed. After all, the thinner the glass, the worse the heat insulation performance, so I want to ensure that the internal zero For the safety of the components, the glass must be at least one millimeter or more, preferably two millimeters thick.

　　 But in this case, compared to a millimeter thick or even thinner glass, the weight will definitely be more than doubled, which will have a significant impact on the overall performance of the entire drone.

But Wang Bin suddenly thought that in fact, one millimeter thick is enough, and there is no need to increase the thickness of the glass, because in terms of heat insulation, in addition to the glass of the fuselage itself, XAC will definitely use other technologies by then. To increase the thermal insulation performance, for example, apply a thermal insulation coating on the fuselage and so on.

　　 After a long time, Wang Bin said to them: "Zong Xiang! Regarding the fuselage of this drone, Tiangong Technology can try it with glass.

Mr. Xiang is also requested not to have too much hope. Although this glass of our Tiangong Technology is advanced, we have not really thought about using this glass to make drone fuselages. No one knows whether it is feasible. The most important thing is that although this drone is not big, the structure in many parts of the fuselage is a bit complicated! "

　　 "Well! I know that we are actually holding a try on this point, using pure glass to make the fuselage. This is the first attempt! As long as you try your best." Xiang Shixiong said.

Then Xiang Shixiong finally opened his briefcase and took out a file of data and said to Wang Bin: "Mr. Wang, these files are the glass data we ordered this time. Please keep them. At the same time, keep it confidential. I won't say much about the specifics. We hope to wait for the good news from you Tiangong Technology."

Then Wang Bin and Xiang Shixiong and others chatted for a while, just as Xiang Shixiong was about to get up and leave, Wang Bin said to Xiang Shixiong: "General Manager Xiang, I don't know your company's Is it necessary?"

　　 "What? The bearing of the engine? Has your company developed any good things during this period? Is it because Professor Hu's research has made a breakthrough?

　　 I remember that Professor Hu was engaged in this area of ​​research when he was on the job. Even after he retired, our company wanted to hire him. In the end, he was picked up by your Tiangong Technology. "

　　 Having said that, Xiang Shixiong continued with interest: "Mr. Wang! Can you tell me about the specific performance of this bearing? If the performance meets our XAC requirements, we don't mind using your Tiangong Technology bearings."

Regarding Xiang Shixiong's belief that this is the glass developed by Professor Hu, Wang Bin did not refute it. He said: “The performance of this bearing is very good, and its maximum high temperature resistance has reached 2300 degrees, and the temperature reaches the limit. Previously, the performance of the bearing has not changed much, and the minimum life of this bearing, according to our estimation, has reached more than 5000 hours.

Of course, this is only our expectation. After all, it has only been a week or two since the development of this bearing. Even if it is tested 24 hours a day, it is only a few hundred hours. So the specific data is still In the test, but according to Professor Hu's calculation, the life of this bearing will never be less than 5,000 hours. "

Speaking of Wang Bin, he took out the bearing that Jiang Zongliang had brought to Professor Hu from the drawer of his desk and handed it to Xiang Shixiong. He said again: "Zong Xiang! This is the aviation we made. Bearings, but manufacturing this type of bearing requires a variety of strategic scarce materials and ultrhigh-precision CNC machine tools, so we do not have large-scale manufacturing. Until now, we have only manufactured a few for testing.

Mr. Xiang, the bearing in your hand is actually only a test product, and it is still a bearing that has been tested for a week. This bearing is still inadequate in terms of accuracy. This bearing is only manufactured using a three-level precision machine tool. ,"
