Turbofan jet engines in airplanes today are less noisy than they used to be. Therefore, birds notice the approach of the aircraft later and react later. So why haven’t grilles been installed on aircraft engines yet?
According to user iXBT.com, there are two explanations for this. Firstly – the problem of birds entering the engine in this way cannot be completely resolved. The most dangerous for the liner birds are during landing or take-off. The speed of the aircraft in this case is about 200 km / h, so in the event of a collision with the grille on the engine, the bird will break into pieces or the grill itself will break and its fragments will fall into it. engine. This will only worsen the situation.
Second reason saving. Such barrier nets will be very expensive, in addition, fuel consumption in this case will increase. This is due to the fact that such grilles will greatly affect the efficiency of the engine, not in the best way.
In addition, the International Civil Aviation Organization emphasizes that only 11% of bird strikes have serious consequences for aircraft. And according to statistics, they encounter birds in only one out of two thousand flights.
