Consumer drones quickly gained recognition around the world. These convenient and useful flying devices help to make stunning videos and photographs, they have become indispensable helpers not only for lovers of photos and videos, but also rescuers, firefighters, ambulances and other important services of the community. However, a fairly reasonable price and multipurpose use served the mass distribution of UAVs, which, as it turned out, entailed a lot of negative consequences. One of them is a threat to civilian aircraft. Specialists from Dayton University conducted a visual experiment in which they used the wing of a light-engine passenger plane and one of the most common and popular drones in the world – DJI Phantom 2 weighing about 1 kg with a battery. Engineers dispersed the UAV to 383 km / h. The speed that the aircraft in question develop at take-off. As you can see, the drone, made of durable plastic and metal, went inside the wing, damaging the outer shell and completely hiding inside. Note that airplanes are designed so that no collision occurs with small birds. Also in the case of birds, even if they collide with an airplane, they will burst in an instant, so they rarely cause serious damage to the wing structure. With the UAV, as we see, the case is completely different. In addition, the speed of airliners is higher than that of representatives of small aircraft and it is to these aircraft that drones can cause significant damage with subsequent unforeseen consequences.
