Yesterday, a younger colleague of mine asked if using continuous ignition in turbulence really prevented flameouts.

The engine in question is a CF6.

I offered my opinion that it is indeed cheap insurance at higher power settings found in cruise and climb, but it's probably more important at lower power settings during descent especially when accompanied by heavy rain like weather found around convective activity.

I tried to explain how the "flame" might be "snuffed" out, not due to lack of oxygen, but the flame itself being "knocked off" the atomized fuel.

It was at this point I reached the limits of my physical explanation and decided to do a search here for more answers.

This seems to be the BEST thread (after a search of the forums) that addresses my question: What exactly is the PHYSICAL/SCIENTIFIC explanation of the flameout during heavy turbulence?

Any physicists out there?
Thanks.
