I'll stick with barit1 asw, just deepen my qs a bit...
To my knowledge (pilot), the "burp" of fuel-hp air mixture from the aft to the fwd and aft again sections of compressor is ejected through the combustion chambers and the exhaust not completely burnt and ignited outside. That should explain the spectacular firebreath of the pix, ain't? My qs was also about overall consequences on engine components after that. barit1 gave also another nice tip to ask for. Why r/trusth and x/wind are more suitable condition for this phenomenon? My engineering past is a long way behind me...I forgot most of the concepts...Uni wasn't exactly the way I wanted to go!
Thanks for the fun
