Methods and apparatus for detecting turbine engine flameout

摘要

A flameout detection system (50) for an engine that facilitates detection of flameout (58) in the engine in a cost-effective and reliable manner is described. A method implemented by the device includes the steps of detecting a rate of change of gas generator speed (56), also described as engine deceleration rate, and declaring a flameout if a deceleration rate of the engine is greater than a pre-determined threshold.
