    Why can't airlines fit their planes with mesh at the front of the engine to avoid birds being sucked into the engine ??

    I guess that will effect the air inflow. Also, a mesh will only stop enterance of birds into engine. But the bird will stay there (due to high air pressure) which can cause some issues of balance and other sort

    Traveling at 800-850+ Km/Hr the supposed screen have to be very strong to withstand a 3kg bird strike. Make them light and the strike may take with it parts of the metallic/composite material of the screen along with the bird into the engine, multiplying the problem rather than resolving them. Make them strong enough to withstand that kind of force and they will be too heavy.

    Then there is the issue of turbulence in air entering the engine.

    Also a mesh at 35000ft appx will be subjected to -50 Celsius temperature and the mesh will act as a suitable surface for icing. Now you may have a bird strike every now and then but icing is a regular thing on all flights. The chunks of ice breaking from the mesh and entering the engine will again create more problems than it resolves.



    In last 50 years or so there have been two or three serious bird strike accidents on commercial flights. Just not worth it keeping in view all the above mentioned regular troubles!

    It will.

    You can have hydraulic mesh and alternate intake systems like in fighters, but it causes weight and complication, a big deal in commercial aviation. These will prevent only low level hits anyway.
    It's better to certify engines that can withstand some bird hits, which is what they do. This investment works in all altitudes.

    I just want giant parachutes.

    You can see the damage a bird strike can do to an aircraft, now imagine if it hits the say mesh-wire cover, and all those pieces of metal being sucked into the engine will certainly do more damage if not disable the aircraft.

    Yeah put a mesh and watch the bird being torn into pieces slowly and each piece going into the engine as usual?
    You do realize the kind of airflow that happens in and out of those engines?
