Yesterday in Denver was the most recent uncontained engine failure to make the news. There seem to have been quite a number of them in the past decade or so.
OTOH, where are all the contained engine failures? A critical part of new engine design/testing is the famous “blade-off” test, in which an engine is operated on a ground-based test stand while a compressor blade is deliberately severed from its hub; the engine is destroyed in the process, but test is considered a success if the engine nacelle keeps any pieces from scattering radially. This is an important safety feature, which would imply that at least a significant portion of engine failures are of a nature that can be contained - yet I don’t recall hearing of many of these. They certainly aren’t as spectacular in appearance as an uncontained failure, but I would still have thought they’d make the evening news.
Is there a stat somewhere? What percentage of in-flight engine failures are contained versus uncontained? For the uncontained failures, how many involve a blade separation that just happened to be unexpectedly energetic (versus a fragmentation of the hub, which is understood to be pretty much uncontainable)?
