This is a link post Bird Vs Jet Engine
isn't it amazing how something so big and powerful can be so delicate?

This is a normal post "They actually have a "chicken gun" they use to fire the chickens into the engines for these tests."
I can't tell if that's terrible or fucking brilliant.

This is a normal post seems to be
I have seen a video of an unlucky (military) ground controller get sucked into the air intake of a military aircraft though; he survived, but only because the intakes on military jets are rarely big enough to ingest a human being wearing bulky clothes and a helmet etc.

Here it is: www.youtube.com/watch?v=O_wticWfA4Q

This is a normal post This isn't a bird strike test
It is a "blade out" test where they have to demonstrate that a broken fan blade will not cause the fuselage/passengers to be damaged/injured by shrapnel.

The engine housing/cowling has to able to contain the explosion/debris. The fan blade which they break/shatter (with explosives, via remote control obviously) is the orange & purple one.

Aero engines can ingest some birds without suffering from structural failure (although the engine might stall/lose power), but not entire flocks of them (especially big birds like geese).

Almost like he has access to some sort of giant searchable source of technical knowledge from his home PC, but enough of that unbelievable science-fiction crap.

This is a normal post I wish
I just remember seeing one of these destructive tests on a documentary about the A380; it's not the sort of thing you easily forget (explosions and fireworks etc.)

Found it: www.youtube.com/watch?v=j973645y5AA

(they use kevlar or some other kind of uber cloth to contain the shrapnel)

This is a normal post So, for clarification then,
was that test succesful?

Seems like an awful lot of smoke / fire / vibration going on in there. Although it's not total catastrophic failure...

This is a normal post I don't know
There was a lot of smoke and fire though; I've seen other tests where that doesn't happen (although the engine is not completely enclosed here. They are just testing the part of the cowling that needs to contain a failure of the front fan; shrapnel coming out of the back of the engine isn't a problem).

The vibration issue is solved by connecting the engine to the wing using pins that are designed to break if the engine vibrates too much (i.e. enough to damage the wing).

They can design for some vibration, but only so much because every blade off event will be unique/not entirely predictable.
