Lesson plan
Compressor stall
A compressor stall is a local disruption of the airflow in the compressor of a gas turbine or turbocharger. A stall that results in the complete disruption of the airflow through the compressor is referred to as a compressor surge. The severity of the phenomenon ranges from a momentary power drop to a complete loss of compression. Compressor stalls were a common problem on early jet engines with simple aerodynamics and manual or hydromechanical fuel control units, but they have been virtually eliminated by better design and the use of electronic control systems such as full authority digital engine control (FADEC). Modern compressors are carefully designed and controlled to avoid or limit stall within an engine's operating range.
