The Compressor Stall Stories

The Compressor Stall Game

A compressor will just pump air in a stable manner till a specific pressure ratio. Thus it’s very clear that the compressor has to be capable of satisfactory operation on a wide variety of rotational speeds and inlet problems. A sustained compressor stall can lead to engine damage and can cause engine failure.

Compressors will get the job done for you, but they’re very, very fussy regarding the airflow across them. Thus, the compressor is just one of the main elements of the gas turbine engine because its efficient operation is the trick to overall engine performance. Real compressors suffer from several loss mechanisms. Thus, making a great adiabatic compressor would call for perfect heat insulation of all areas of the machine.

Compressor Stall – What Is It?

The engine is going to be sent to the engine shop for disassembly and a comprehensive inspection work-up for more evaluation,” explained Roberts. It would not stall, it just would not restart. The engines wouldn’t spool up, either from windmilling or with the aid of the auxiliary power unit. Usually it recovers on its own. The entire engine was made to keep the compressor operating a little distance beneath the surge pressure ratio on what is called the operating line on a compressor map. Turbocharging can boost power output for a particular capacity or boost fuel efficiency by allowing a more compact displacement engine.
