Flameout

Flameout”: a state when a gas turbine engine fails due to insufficient or excessive fuel sprayed into the combustors, causing an abrupt extinction of the fire, leading the engine to shut down. This state can occur during the initial stages of the engine’s combustion process or at a later stage in the engine’s operation. It can happen due to several reasons, such as fuel starvation, fuel contamination, compressor stall, or blade fouling. Flameout can result in a serious accident if it happens during takeoff or landing, during low level flight, or in adverse weather conditions. The consequences of such an event can lead to the loss of propulsion, hamper the aircraft’s thrust-to-weight ratio, or even cause structural damage. Flameout is an essential factor to prevent when designing gas turbine engines for aircraft and other applications.
