A330 Compressor Stall at Takeoff

The side view adds a little more excitement to it. The rudder needed to reign that puppy in is impressive.

In theory I get how a compressor stalls, but how can this happen just going along the ground on takeoff? Don't you need a drastic angle of attack change at the inlet to stall the blades? Can swirling winds or gusty conditions cause it if they vary enough?

Could be a fault with the inlet guide vanes or some other internal component of the engine.
 
Is it the main fan that stalls or the small compressor sections that stall? Why the explosion? is that basically unburnt fuel firing when it reaches the hot air of the back side of the compressor, sort of like an after fire in the exhaust of a car?

Its the small compressors that stall. The explosion is a momentary reversal in the movement of air through the engine. So instead of going from front to back, it goes from back to front.

Even a slight crosswind during spool up in a 727 will cause a distinct "POP!" on the #2.

Granted I don't fly high bypass airplanes, but the vast majority of stalls I have seen or known others to have were the result of either FOD (structural damage to the motor), or faulty fuel controllers. I had one pop stall during high AoA maneuvering, but that cleared almost instantly. The stalls you lose/shut down a motor for are generally not related to angle of attack.

The S duct didn't like crosswinds. The Mod A inlet helped a lot but you still needed to get rolling first in higher crosswinds before advancing the TL on #2

They also can complain in reverse at lower speeds too
 
This video makes a good point in why as a Multi student we brief the takeoff with engine failure before reaching Vmc. Directional control and power to idle. Same on the Seminole as the A330.

Directional control is paramount.
 
Nice to see some action at the local (UK) airport. Glad AA Delta United & US still fly in there, they're gone from Gatwick.
