First of all, the big wing of an airplane is the wing, which is a crucial part. It is not only demanding, but also difficult to manufacture, which determines the stability of aircraft flying height and distance. In the requirements of Yun -20 transport aircraft, it is more important to have high accuracy, long service life and fatigue resistance, which requires high workmanship accuracy, otherwise problems are likely to occur during flight. Moreover, the wing, as an integral fuel tank, must be highly sealed, otherwise there will be great friction during flight.
Wing * * * to break through more than a dozen engineering technologies, such as the precise docking of the most difficult weak rigid parts, we must ensure that the docking accuracy is very high, otherwise it is difficult to move 1mm, and we see that its wing is made of aluminum alloy, but it looks like noodles. A wing needs to drill tens of thousands of holes, and it is connected by automatic drilling and riveting equipment to ensure stability.
Finally, we should make good use of data measurement, such as making a large number of measurements with digital equipment and then analyzing them manually. To provide support for docking, attitude adjustment and other processes. Then there are the parameters in the flight process, such as the pressure on the weight of goods under different conditions, the attitude of the aircraft and so on. It is difficult to get the best wing attitude, improve equipment and improve flight efficiency by constantly monitoring and finally changing these things.
