Goose meets Jet Engine

Hence the reason the Airbus went down. Holy cats. You can hear the broken-off fan blades clattering as they hit the ground.

Wow....really did not imagine it being that violent

Well, I`m not a pilot. But, I bet that would focus your mind!

where do they find the geese volunteers for these studies?!?!

SHould we be speculating on this when the investigation of the goose hasn't been completed yet? Has the family of the goose been informed?

That looked more like a blade-out test to me, like they actually exploded one of the fan blades to see if the engine housing could handle the flying blade pieces. I didnt actually see any bird carcass go into the engine.

Are there any professional engineers on here, what kind of test was this?

I wasn't an engines guy, but a Aerodynamics/Structures guy. If you didn't see the bird, it's possible that the quality of the video causes you to miss it. Most likely it was launched into the engine at a fixed speed (say 200 KTS+).

From what my old co-workers told me, the birds they launched at structure used to be frozen, too. Nothing like making the tests a little more conservative.

I believe MB was an Engines engineer type, maybe he'll chime in.

Judging from the movie I think you're correct. It's a containment test. The orange blade you see would have a charge on it, to also identify it for the high speed footage. Watched a lot of these in college, they look really cool in slow motion.

What a tool. I hope this guy knows that every proffesional pilot that reads this is laughing their ass off at him.

I believe he's also a former/retired single anchor type, and thus, a professional pilot himself. It's at least somewhat more cogent than the drivel the media put out, anyway.

Having done blade out tests on a PW4098s and other PW4000 series engines while with Pratt & Whitney, I'm saying that's a blade out test. The chicken gun would be in frame if that was what they are doing.

Also, the compressor/fans tend to chop up the birds, normally trashing the motor and it quitting, but having a such a massive blade failure is not common.

Also, see the orange blade? I'll bet that's the one they blew, and in the high speed (this is the real time video) it was much more closely watched.

Aha. I thought that was just a visual reference as to the RPM of the fan. Makes sense.

I certainly hope not. I can totally see the flight sim dorks and wannabe's doing something like that, but certainly not a dude with extensive experience. He would also know that video was a containment test and not a bird strike.

Like MB said, I took a large bird down a motor in the Hornet and all it did was slightly twist three fan blades on the first stage. Bird strikes aren't that spectacular (and smell awful).

Frozen birds are actually a mistake. A frozen bird will do much much much more severe damage than a thawed bird. It's like the difference between a nerf ball and a baseball. Conservative doesn't quite cover the difference...
