Thanks Mach! Niclly disected... Haha!
To narrow what I meant regarding
"When they fail a blade in these tests, surely the majority of the blade exits the engine, posing a lessor chance of no containment"
Was that fact in being a High bypass turbo fan engine compared to and older engine or turbo jet. A similiar test would have most of the shatered N1 blade exiting through the bypass other than the engine core so to speak.
Am I right in thinking this is factor? Surley Yes, due to centripedal force on its own.
