Hello everyone, I am your self-media writer. Today, we're going to talk about the topic of why we use rivets to build airplanes, and don't rivets affect wind resistance when welding is smoother? This topic may surprise you, because we usually only pay attention to the shape, speed and comfort of the aircraft, and rarely pay attention to these seemingly insignificant details. But, did you know that these "little things" play a vital role in the construction of aircraft. Next, let's unveil the mystery of rivets together!
First of all, we need to understand that an airplane is an extremely complex and large piece of machinery, and every part of it needs to be accurate to the millimeter. In this process, the rivet is like the "screw" of the aircraft, connecting the various parts tightly together to ensure the stability and safety of the aircraft.
So, why not welding, which does make the connection between parts smoother, but it also has its drawbacks. First of all, welding generates a lot of heat, which can cause damage to the aircraft's materials. Secondly, the welded parts cannot be disassembled again, which is a big limitation for the repair and upgrading of the aircraft. Rivets, on the other hand, do not have these problems, and they can be easily disassembled and replaced, greatly improving the efficiency of the aircraft.
When it comes to wind resistance, you may feel that rivets increase the wind resistance of the aircraft and affect the speed of the aircraft. Actually, this is a misconception. The shape and size of the rivets are carefully designed to not only guarantee the stability of the aircraft, but also reduce wind resistance. Moreover, the surface of the aircraft is not completely smooth, and there are many designs designed to reduce wind resistance. For example, the wings of airplanes are usually streamlined, which is to use the principles of aerodynamics to reduce wind resistance.
Here, I would like to tell you a little story. The story takes place in the 30s of the 20th century, when aircraft manufacturing technology was still very backward and the safety of aircraft was low. Once, a plane suddenly lost control in flight and ended up crashing. After investigation, it turned out that one of the rivets of the plane was loose. This little rivet actually caused the crash of a plane. Since then, people have begun to pay attention to the importance of rivets in aircraft construction, and they have begun to study how to improve the quality and stability of rivets.
After decades of hard work, rivets have changed dramatically now. Not only are they of higher quality, but they are also more stable. Suffice it to say that without rivets, there would be no modern aircraft that we see today.
So, the next time you see an airplane, look at those seemingly inconspicuous rivets. Although they are small, they carry the weight of an airplane and protect our lives.
