Thus the fix is to minimize a short term oil leak of this magnitude.
Yeah, that will address this particular failure sequence (overheated disc flange).
But decades of experience says there are potentially other causes for shaft separation, and the fundamental issue is the lack of any provision in the Trent to destroy the runaway turbine airfoils prior to disc burst.
I will grant that the six-second interval between N2 compressor spooldown and N2 turbine burst might yield promise for a software fix >> namely, fuel cutoff if sensed N2 is too far out of whack.
