Which constraint causes after-burning instability in a jet engine?

💡 Explanation

Exceeding flammability concentrations (LEL/UEL) causes after-burning instability via deflagration to detonation transition (DDT) because the mixture reactivity runaway, resulting overpressure damages the engine; therefore detonation, rather than deflagration becomes dominant under limited conditions.
