Chapter 69 (1/2)
After listening to Xiang Shixiong's words, Wang Bin thought about the performance of his glass.
Indeed, as Xiang Shixiong said, if the fuselage of this UAV really uses this glass, as long as the engine is strong, it is not impossible to reach the speed of Mach 4, but the temperature of the aircraft fuselage at this time will also rise to the limit that this glass can bear.
And such a speed can only be achieved at an altitude of more than 10000 meters. If the altitude of UAV is less than 10000 meters, the temperature generated by the friction between glass and air will 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 tolerated.
So Wang Bin said: ”indeed, if we use this glass as the fuselage, the speed of Mach 4 at high altitude is not a problem. Even at low altitude, the speed of Mach 3 can still be borne.”
”The specific data have been calculated by our scientific researchers of XAC, which is absolutely no problem. The biggest problem now is whether Tiangong technology is able to use this glass to make the fuselage of this UAV.
After all, the fuselage of this UAV is not made up of flat glass. Take the wing of this UAV for example. The wing is an integrated wing, which must be completed at one time in the production process without any deformation. Otherwise, the UAV is very easy to get out of control in the flight process, especially in the high-speed flight process.
In addition, there is the segmented part of the fuselage, which is also very difficult in technology. The segmentation of the UAV fuselage requires that there are no pricks or bulges on the surface. This is a little burr of the aircraft with a speed of Mach 4, which may lead to problems of the aircraft.
Finally, there should be no errors in the nose and tail,... ”
With the introduction of Xiang Shixiong and the two engineers, Wang Bin has a basic understanding of the technical difficulties in manufacturing the UAV fuselage and wing. At the same time, he is also thinking about how to solve these technical difficulties.
After Xiang Shixiong introduced all the technical difficulties of the UAV fuselage, Wang Bin fell into thinking. The manufacturing of this UAV fuselage is a great challenge for Wang Bin.
The first is the thickness of the fuselage glass. According to their previous introduction, Wang Bin believes that the thickness of the fuselage glass of this UAV cannot be too low, at least not less than one millimeter.
