Jet Turbine Engine vs A Bird....Guess who wins!

Bird vs. Jet Engine...

Below is video of an Rolls Royce engine on a test stand undergoing a 'Bird Ingestion' test. This test is accomplished by firing a bird, [generally a dead chicken complete with feathers and internal organs] at the engine. The bird's weight is a function of the inlet and fan diameter, This test is considered a success if the failure was completely contained, [i. e. No engine parts penetrated the engine cases or the aircraft cowling and there is no sustained external fire]. It does not take long for the engine to digest the bird as well as a significant number of its' own blades & vanes. The video lasts 33 seconds and the bird is fired into the engine at the 17 second mark......


Shake, Rattle, and Roll..............

Now you have some idea what the pilot of that US Air flight faced when he ingested birds into both engines simultaneously!! It also gives you a fair idea why the one engine's mounts failed after the water landing and dropped off the wing.
