Video Of A380 Fan Blade Off Test

Fri Mar 02, 2007 2:05 am

Donno if it was posted before, but here's video of A380 RR Trent 900 Fan Blade Failuare Test.


All I can say is Wow on the sheep power of that thing running at full and when it goes off.

All I can say is amazing! Sad that they had to destroy such a beautiful piece of engineering.

How many sheep does it use?

I agree, but better to test and be safe. Great video, thanks to the thread starter for sharing.

Yes, i posted it a half year ago, though i cant find my thread with the sh*t search engine. However the video is amazing one engine = 4 tons of solid gold.  eyepopping

4 tons of solid gold

There is no way that each engine cost $84,966,400 US dollars. That would mean a set of 4 costs $339,865,600


Gold $663.80 per ounce

16 ounces per lb equals 1 lb of gold at $10,620.80

4 tons equals 8000lbs

8000lbs times 10,0620.80 equals $84,966,400

 Wow! Huh, i didnt sum it but of course you are right. In the full video they mentioned it. Maybe that was some years ago(2000?) when Gold prices didnt rise so much or discovery channel just cant sum.

It looked like the building shook when that blade came off. Is that due to the explosive charge or was that actually due to the energy released when the blade came off? I would be very, very concerned if I heard an explosion like that -- and the plane shook -- like that building did while over the middle of the atlantic.

It is from the blade coming off. The explosive charge is tiny any would sound like a gunshot.

It sent shivers down my spine. It's an amazing advert for British engineering that we can build such an awesome piece of equipment. And I'm also very proud that it comes from my area.

Not to take away anything from the energy released from such a fan blade out event, the video does use certain amount of artistic license and dramatization of the event, especially the shaking of the camera at the monitoring station. The engine will get a tremendous shake for sure, but feeling the building shake like that is just director's extra little touch.

In the plane, you will probably feel a jolt but that's the entire point of the FBO, to keep the blade out event under control. Other parts of FAA certification requirement include containment, vibration response, load imbalance from non uniform fan and engine control. (i.e Pilot or control must still have enough authority over the engine power to at least shut it down safely without the engine going out of control)

The explosion and the flames are real though, and so is the shaking, vibrations and swelling of the fan case and fan cowl. Remember, the test cameras used for such a test are special high frame rate cameras, that captures up to 10,000 frames per second. Normal 30 fps camera won't pick up much vibs and deformations at all.

Good video! Thanks for sharing

Nope. The Fan Blade Off and Bird Ingestion tests are completely different.
- FBO - Gotta contain all high energy debris. Obviously, the engine is not expected to continue producing thrust.
- Medium Bird Ingestion - (The usual test you see video of). The engine needs to cope with approx 8 medium sized birds hitting it at take-off speeds, and still be able to produce 75% of rated thrusts. The reasoning is that medioum sized birds are flocking birds, so could affect all of the installed engines. You don't want to lose all thrust.

There is some overlap and wrinkles regarding Large Birds and LFBs, but I'm trying not to get too technical.

Hope This Helps...

Thanks TepidHalibut for the explanation. I was discussing about this test this morning with a few colleagues and I was told by a former Boeing engineer that they don't use frozen chicken no more to simulate the bird ingestion. They use something like an hard ball, maybe the size of a handball, that is thrown in the engine for this particular test. Can anyone confirm the information and give more detail about this ''ball''.

Last I heard they still use real birds. Not frozen ones because your chance of encountering a frozen bird in flight is almost nil. The same can be said for handballs. When testing engines the conditions have to be realistic. I don't think a handball would be realistic enough.
