SU-30 High AOA Video

Some of that is along the same lines as their "Cobra" maneuver. Sure it looks pretty at an airshow, however bleeding all your speed off in a single maneuver like that eliminates all your energy...which will get your killed very fast. I think the radius of turn on that plane is badass along with the ability to fly almost sideways to engage a target, which would be the big benefits there. Although after doing some reading, it appears that only the "civilian" test pilot can make it fly like that. The Navy has actually had a few test planes for all of the design concepts the 30 incorporates, so its not stuff we dont already know about.

I haven't taken any aerodynamics classes or anything so could you explain how the engines would stall?

Its all about disruption of airflow into the engines. Engines running at high power like to see a smooth straight flow of air. High angles of attack disrupt this and cause turbulence. However there are ways of altering the intake to account for changes in AoA. Some designs included variable intake geometry, (though this is usually reserved for high speed supersonic flight), creating a seperate intake route on the top of the fuselage, etc. Actually very high AoA isnt as bad for an engine as negative AoA where the upper fuselage and wing can actually block airflow into an engine.
Although are all those maneuvers truely practical in todays Air-to-Air engagements that are mostly beyond visual range?... dunno

awesome, that clears it up! thanks!
When the manuvers you see are performed engines are most likely at idle. Thus a significantly lower chance of a compressor stall. If he kept the power up the jet would just climp up into a loop.
He add power as thenose falls and engines spool up as it comes back to the relative wind. And flies away. There is loss of altitude, just hard to see at this aspect.
