I'm probably jumping into the realm of engineers here. Are containment tests today in developemnt of Hi bypass engines still relevant? Or are the regulators and the manufacturers missing something.
N1 Fan blade seperation tests seem to be the standard examples used in testing of engine containment. Probably, and most definetly for the old Turbo Jet for sure. But are these huge by-pass designs now making this test out dated. When they fail a blade in these tests, surely the majority of the blade exits the engine, posing a lessor chance of no containment.
With the likes of QF32 incident, and quite a few CF6-80 uncontained failures and probably others I havent listed in the last few years. I just watched again the video ABC on QF32 and brings to mind one cant test the disintegration of a 200kg turbine wheel at 1000s of rpms..
