What is the procedure for removing the accumulation of dirt deposits on compressor blades called?

The procedure for removing accumulation of dirt deposits on compressor blades is referred to as field cleaning. This process is typically conducted in the field, meaning it occurs while the aircraft is on the ground and not in the shop or during a full maintenance overhaul. Field cleaning involves using specialized techniques and products designed to safely and effectively clean the compressor blades without damaging them.

This approach helps maintain engine efficiency and performance by ensuring that the airflow through the engine is not impeded by dirt and contaminants. Keeping compressor blades clean is crucial for the overall health of the turbine engine, as any build-up can lead to reduced performance, increased fuel consumption, and potential engine damage over time.

While engine wash, blade refurbishing, and compressor overhaul are related to engine maintenance, they pertain to more extensive cleaning or repair processes. Engine wash often involves cleaning the entire engine, while blade refurbishing implies a repair or restoration of the blades rather than routine cleaning. Compressor overhaul is a more comprehensive maintenance task that typically includes disassembling the compressor for inspection and repair, beyond just cleaning the blades.
