Chapter 69 (2/2)

Otherwise, the heat generated by the aircraft when flying at high speed will definitely make the internal parts of the UAV unbearable. After all, the thinner the original thickness is, the worse the thermal insulation performance is. Therefore, to ensure the safety of internal parts, the glass should be at least one millimeter thick, preferably two millimeters thick, but in this case, Compared with the glass one millimeter thick or even thinner, the weight will definitely more than double, which will also have a significant impact on the overall performance of the whole UAV.

However, Wang Bin suddenly thought that in fact, a 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, Xifei will certainly use other technologies to increase the heat insulation performance, such as coating the heat insulation layer on the fuselage.

After a long time, Wang Bin said to them: ”President Xiang! Regarding the fuselage of this UAV, we Tiangong technology can use glass to try. Please don't have too much hope. Although the glass of Tiangong technology is advanced, we really haven't thought about whether it is feasible to use this glass to make the fuselage of the aircraft. Most importantly, although this UAV is small, the fuselage is very small The structure of many places is somewhat complex! ”

”Well, I know. In fact, we have a try attitude towards this. After all, using pure glass to make the fuselage is the first attempt! As long as you try your best,” Xiang Shixiong said.

Then Xiang Shixiong finally opened his briefcase, took out a document data and said to Wang Bin, ”President Wang, these documents are the glass data we ordered this time. Please keep them. At the same time, pay attention to confidentiality. I won't say more about specific information. We hope to wait for the good news of Tiangong technology.”

Then Wang Bin and Xiang Shixiong talked for a while. Just when Xiang Shixiong wanted to get up and leave, Wang Bin said to Xiang Shixiong, ”President Xiang, I don't know if your company needs bearings for aircraft and engines?”

”What? Engine bearings? Has your company developed anything good these days? Has Professor Hu made a breakthrough in his research? I remember Professor Hu was engaged in this research when he was on the job. Even after he retired, our company wanted to hire him. Finally, you Tiangong technology picked him up.”

Speaking of this, Xiang Shixiong continued with great interest: ”Mr. Wang, can you talk about the specific performance of this bearing? If the performance meets the requirements of Xichang, we don't mind using your Tiangong technology bearing.”

Wang Bin did not refute Xiang Shixiong's view that this glass was developed by Professor Hu. He said: ”The performance of this bearing is very excellent. Its maximum high temperature resistance reaches 2300 degrees. Before the temperature reaches the limit, the performance of the bearing will not change much. At the same time, the minimum life of this bearing has reached more than 5000 hours according to our expectation.

Of course, this is only our expectation. After all, it has only been a week or two since our bearing was developed. Even if it is tested 24 hours a day, it is only a few hundred hours. Therefore, the available data are still under test, but according to Professor Hu's calculation, the service life of this bearing will never be less than 5000 hours. ”

With that, Wang Bin took out the bearing he had asked Jiang Zongliang to fetch from Professor Hu from the drawer of his desk, handed it to Xiang Shixiong, and then said again: ”Mr. Xiang! This is the aviation bearing we manufacture. However, because manufacturing this bearing requires a variety of strategic scarce materials and ultra-high-precision CNC machine tools, we have not made it on a large scale. Until now, we have only made a few for testing.

Mr. Xiang, the bearing in your hand is actually just a test object, and it is also a bearing that has been tested for a week. There are still some deficiencies in accuracy. The bearing is only made by a machine tool with three-level accuracy. ”
