The future is a strange thing. Here it is, and here it is already the past. At this point, another time becomes the future. So we constantly catch up with him and discover his secrets.
Ten, twenty, thirty years pass, and you seem to be in the future, but it's hard to see how it comes. Look back ten years ago — then you could not have thought that you could not live without the Internet and a smartphone in your pocket. What awaits us in the next decade? A century? Millennia? The future is such a strange thing that you can try an infinite number of times to guess what will happen in ten years, and in some ways you will be right, but this rightness will be drowned in a crowd of new products that will demolish the past like a crane in an old building.Humanity has long been trying to create a silent plane, but so far it turns out so-so
The first aircraft in the world appeared at the beginning of the XX century and made it possible to travel long distances in a short time. The risk of crashing in an airplane is much less than in a car, that is, it is a very safe means of transportation. But all planes at the moment have one big disadvantage — they make a lot of noise. This is especially difficult for military aircraft, which emit noise at 140 decibels when taking off. Such a loud noise can lead to pain in the ears, because the human hearing can hardly withstand such a load. And, most importantly — because of the noise, combat aircraft can be quickly spotted by enemies. But recently, scientists have found out how to create silent aircraft.
