Explosion hypothesis, shredding of the cowl and what appears to be scorching, the source - I have no idea, there should never be an explosive atmosphere in that zone of the engine.
The 380 out of Singapore (Qantas) experienced a departed IPT. It was number two. And was an extremely serious event. No fatalities. RR Trent, supposedly there was an “oil fire”, in the stator cave which caused an over speed of the turbine, which turned its rotor into liquid metal bearing. It’s in here somewheres.
Partial sever of the forward wing spar, and uncontrolled throttle on number one, plus a serious fuel leak made the emergency landing quite an accomplishment.
That one? Certainly not a fan issue, a very high energy turbine.
