If a turbine disk comes apart, nothing short of battleship-grade armour, and lots of it (or Olf's skull) would stop a chunk of metal that large, with that much energy, going precisely where it was destined to do under Newtonian rules.
RR do have a problem, but not because the engine casing failed to contain a disk failure - they're in the merde because the disk came apart at all.
Seems to me - as a layman - that the failure of one engine out of four wasn't the problem. The problem was the number of hydraulics and other systems that were cut when the disk checked out.RR do have a problem, but not because the engine casing failed to contain a disk failure - they're in the merde because the disk came apart at all.
Given that all routes of an exiting disk will, I presume, follow a single flat plane, would it not be possible to arrange the hydraulics etc out of this 'plane of risk'? I appreciate that part of the exit plane is occupied by the fuselage, but you'll just have to live with that.
It's one of those billion to one incidents, you think you have enough back-up systems but you have nothing if they are all cut at the same time. Remember United Airlines Flight 232 DC-10 that eventually crashed on approach to Sioux City? When the fan disk exploded on the number 2 engine it simultaneously severed the main hydraulic system and both backups.
