Why is compressor field cleaning performed on turbine engines?

Compressor field cleaning is an essential maintenance procedure performed on turbine engines primarily to prevent performance degradation and damage. Over time, compressors can accumulate dirt, dust, and other particulates that can impede airflow and reduce the efficiency of the engine. This buildup can lead to a decrease in thrust and an increase in fuel consumption, compromising overall engine performance.

In severe cases, if not addressed, the accumulation of contaminants can lead to excessive wear on the compressor blades and other internal components, potentially resulting in more severe engine damage or even failure. Therefore, regular cleaning of the compressor helps maintain optimal performance levels, ensures efficient operation, and prolongs the lifespan of the engine components.

While other factors such as airflow and aesthetic considerations may play a role in maintenance practices, the primary goal of compressor field cleaning is to safeguard the engine's performance and longevity.
