More Huffin' and Puffin' - certification tests

Here are some tests a new engine model must survive before going into production:


NOTE: This video is incorrectly labeled. It actually shows the result of a fan failure containment test. A selected fan blade is "blown off" at it's root, producing an explosion of shrapnel that must be contained by the engine cowling. Furthermore the structure of the engine must deal with the resulting unbalance condtion. (Thanks to Luke for the correction!)...


For a more complete look at the certification tests of the Rolls Royce Trent engine, including the containment test:


Despite the best-layed attempts in certification to replicate life on the line, sometimes even one bird in the wrong place at the wrong time can produce engine problems (assuming this video is what it seems to be):

The second video isn't a bird strike test (I'd hope a Trent would be much tougher than that!) It's actually a fan blade failure test, to verify that the resulting cascade failure doesn't eject any debris from the cowling and possibly into the aircraft.

Thanks Luke. My bad - I looked for a more correctly-labeled version of this video but couldn't find one. I've edited the introduction and added another video of the Trent engine certification.

Thanks for the sharp eye!

The last video is genuine - it allegedly ingested "2 large birds" on takeoff. Made the news at the time.

Man, you always seem to find some great videos!
