How damaging is it, really? Don't they just splash right through the main fan and drain into the bypass airflow? I'd understand the damage if a guy got flushed.

The meaning of life is curiosity; we were put on this planet to explore opportunities.

Suck, Squeeze, Bang, Blow. Intact bird at intake, Molecular bird at exhaust. Of course, this applies to small birds. A large bird such as a vulture or eagle might bend a fan blade or two. Any engine that ingests a flock of hundreds on takeoff, though, is in grave danger. That would be the same as total engine failure. The larger the engine, of course, the more birds it is able to process.


it's getting harder not to tell people they are really odd if they think an airplan can be sexy.

It's what's known in the industry as "Shredded Tweet"

Most engines are designed to move any foreign object to the fan sction thus sparing the core engine from damage. If there is evidence of core penetration most maintenance manuals call for a boroscope inspection within a set time, sometimes before further flight.

Birds usually disintigrate when they hit the fan and are slung outward due to centrifugal force. Most of the bird goes through the bypass duct.

I remember one particular bird strike inspection where a good portion of a duck became lodged in the oil cooler of a CF-34 engine. We really wanted to just replace it, but the company refused since it costed upwards of $40K. Th engineers at GE suggested that we boil the cooler in a pot of water to remove what was left of the duck. It worked, we had a clean oil cooler and a pot of duck soup!  Smile/happy/getting dizzy
