Shock As Plane Engine Bursts Into Flames

Aledgedly a surge, but would a surge be able to create a large hole in the engine cowling

[MarkK]

The hole will have been caused by parts of the engine breaking off and failing to be contained either due to the surge or some other reason.

A surge should not cause that kind of damage and the engine should contain broken parts so I'm guessing something has gone badly wrong with that engine.

Ummm, a running engine is ALWAYS in flames. It's when they go out you have to start worrying.

So the headline should have read "Shock as Plane Engine Flames Burst Out". Typical of the poor reporting standards we have today.

'Engine Malfunctions' would have sufficed.

It seems an odd location for an uncontained engine failure, way back in the turbine section. I thought all engines now had to be able to contain the debris in the case of such a failure, but perhaps that is only a single blade-off in the LP compressor.

It should be interesting when the facts appear.

The surge is just a result of disrupted airflow through the engine it isn't the cause of the damage but the result of something else damaging the engine, the sparks are probably from something rubbing against the casing.

Whatever caused the surge was also uncontained in the engine pod so it was fairly major. I would expect a blade failure to be contained so possibly a disc (the bit that the blades are attached to) failure?

It seems to be the HP compressor immediately aft of the combustion chambers from looking at this diagram. Blade failure/stage seems likely from that. I doubt a surge caused it, but the failure might have caused surge like symptoms.....before a part of the engine tried to escape that is.

Not HP compressor, it is defintely hot end.

Looks like either HPT/IPT disc burst or blade unzip...

my mistake, I meant the high pressure turbine stage aft of the cans
