When it comes to modern fighter jets, we often think of them as precious works of art, not easy to touch. After all, these high-value flying machines invest a lot of effort and money in maintenance, and the average person is unlikely to easily approach them, let alone step on them. But there are some surprising answers to the question of stealth planes and whether they can be trampled on.
Let's start with one of today's most advanced fighter jets, the U.S. military's F-22A stealth fighter. It was once believed that the outer coating of stealth fighters is very fragile and cannot be stepped on casually, otherwise it will damage their stealth performance. However, at a Dubai air show, the US Air Force F-22A stealth fighter caused a sensation, because during the ground display, four US soldiers actually stood on the fuselage of the F-22A to take the oath of the flag, and they did not wear shoe covers, directly wearing military boots to stand on the back of the aircraft.
This scene made people rethink their perception of stealth aircraft. Isn't the stealth coating as fragile as we think? In fact, the coatings of stealth aircraft are both strong and strong, they are capable of withstanding considerable weight. Even if pilots or ground crew wear shoes and step on them, the damage to the aircraft's coating is minimal. This is surprising because previous wisdom has been that stealth coatings are extremely fragile.
However, the real damage to the stealth coating is not the human pedaling, but the aerodynamic impact and deployment environment during flight. When stealth fighters fly at high speed and maneuver, strong airflow impacts can seriously affect the firmness of the stealth coating, especially near the air intake and aerodynamic airfoils. In addition, different deployment environments can affect the coating. Moisture shortens the life of the coating, while sandstorms, dust storms and high temperatures can reduce the firmness of the coating and even cause the coating to blister, crack or fall off.
Thus, from the point of view of aerodynamic shock and environmental factors, the impact of stampeding on the stealth coating of the stealth fighter is minimal. In fact, the main dependence of stealth effect is the structural stealth of the aircraft, and the coating is only part of it, and its stealth effect accounts for less than 10% of the total. Therefore, even a slight damage to the coating will not seriously affect the stealth performance of the fighter.
As for the question about fighter skinning, there are also some misunderstandings. The skin of the fighter, although seemingly fragile, is actually quite strong. Even if a dozen people go up and step on it, it will not cause any damage to the skin. This is because the wing of a fighter is the most important force part, and in high-speed flight and maneuvering actions, the wing is subjected to a huge aerodynamic force, and if the structure is insufficient, problems will occur long ago.
All in all, fighter jets are not as vulnerable as we think, and the prohibition signs and norms on aircraft clearly define where to step on. Different countries have different cultures and approaches to aircraft, with some countries allowing people to approach them at will, while others are more cautious. After all, allowing people to visit and experience advanced fighters is an important way for countries to improve military and civilian morale and pride, but attention needs to be paid to protecting the equipment and coatings of fighters when opening up to avoid unnecessary damage. So, for these high-tech military aircraft, they may not be as easily injured as we think. Instead of treating them too carefully, think of them as tools for our use, because from the J-20 to the walk-behind tractor, they exist for better production and life.
