(1) Why can't planes take off and land in thunderstorm weather? Are they afraid?

Recently, there have been frequent thunderstorms, and many people who want to travel by plane have doubts. What should I do if the plane encounters a thunderstorm in flight? How to protect the plane from lightning? Is there a lightning rod? Basically, planes are not equipped with lightning rods, because lightning rods lead the charges in the air to the ground, and planes fly in the sky. The so-called "lightning rod" on the plane should be just a metal bump for corona discharge. When the plane is flying, the static electricity generated by friction can gradually release the charge through the "lightning rod", and it can also be discharged by the "lightning rod" if it thunders. It is said that planes may be struck by lightning every 10,000 miles. However, because the chassis is mostly a conductor, when an airplane is struck by lightning, the current will flow through the chassis and be discharged by the lightning rod extending from the fuselage or wing, and will not enter the conductor to harm the passengers inside, but the magnetic field formed by strong current will have an impact on the electronic or electrical system on the airplane. But what if you are struck by lightning? On the average, fortunately, this powerful current will only flow smoothly through the fuselage or wing skin, leaving a small ablation hole or gap, which is not serious for flight. Modern new aircraft have structural fuel tanks, which are well sealed and prevent spark detonation. However, if these charges are not released, once the plane lands, they will try their best to vent. For example, once people and oil tankers get close, these charges will wait for an opportunity to release all electric energy, resulting in "fire jumping" phenomenon, leading to casualties, equipment damage, and even igniting oil and gas explosions! Therefore, when the plane flies, it is necessary to try to discharge the charge. If it is a small plane, the accumulated charge in the fuselage will not be too much, and the wing tip can discharge itself during flight. However, if it is a large aircraft, an "electrostatic discharger" will be installed on the main wing or tail wing of the aircraft, which can discharge through the tip and release excessive accumulated electrostatic charge into the atmosphere during flight. Some planes even have more than 65,438+00 electrostatic discharge devices. When an airplane is landing or maintaining, it must be connected to the grounding bolt with a grounding wire, so that the residual charge can be safely guided to the ground, and the airplane can be kept at the same potential as the ground to avoid induced discharge or lightning strike. In this way, the plane will not be afraid of "heaven" and "earth"! But what if the plane is about to take off? At this time, the friction between the plane and the atmosphere is not serious, but because it is not grounded, it is not good to be struck by lightning, so I have to seek money myself! At present, there are probably two ways to reduce the probability and harm of aircraft being struck by lightning: Komatsu blog-fine collection 1. Use many lightning rods extending from the fuselage or wing to discharge. 2. Connect or cover the poor conductor part of the bushing with a good conductor to shunt current and reduce damage.
