When there is abnormal airflow within the compressor it creates a compressor stall. This can cause a decrease in compressor performance. This decrease can range from something that is hardly noticed like a quick drop in engine power that recovers quickly. Or it can cause serious problems like complete compression lost. A compressor surge occurs when the compressor has lost all power. In gas
. turbines the layout of t he compressor surge line causes unsteady operating cycles. Gas turbine compressor stall and surge can make it less durable and decreases its performance.
