What is a compressor stall in a jet engine? A compressor stall in a jet engine is a circumstance of abnormal airflow resulting from the aerodynamic stall of aerofoils (compressor blades) within the compressor. … Compressor stalls cause the air flowing through the compressor to slow down or stagnate and sometimes result in reverse flow.
What prevents a compressor stall in a jet engine? Then engine control systems, such as Fadec (Full-Authority Digital Electric Control), are programmed to keep the operating point of the compressor well away from the so-called stall or surge lines.
What is compressor stall on gas turbine? 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.
How do I know if my compressor is stalling? A compressor stall occurs when there is a disruption or breakdown of airflow through a turbine engine. It can usually be identified by a loud bang, pop, or buzzing sound. Expect to feel a loss of thrust, see your RPM winding back, and your EGT/ITT/FTIT either increase or decrease based on your altitude.

What is a three phase air compressor?
