Would be interesting to see where that is in the cut-away drawing I posted above
I think it is probably roughly like this:
I`m no engineer for sure, & my thinking will probably get shot-down, but the part nearest the central shaft which clearly
shows it`s broken, & which some on these pages suggest probable cause for failure, due to it`s modest diameter isn`t
it less likely that this be a cause of the problem, but more as a result of a problem forward of it, be it blades ( my theory
when I first saw it ) or at least a larger diameter component, that would ultimately exert far more centrifugal force or energy?
It`s been suggested a blade couldn`t cause such an outcome, but if said blade or multiples were ingested in a certain way,
particularly with the flying conditions, could you be certain to rule it out? I`d have thought the front fan blades would have
been the part(s) exerting the most energy by some margin, certainly ahead of the core at least.
