🔍 Key Concepts

• Off-line water wash procedures for gas turbine compressors • Purpose and function of Variable Stator Vanes (VSVs) in an LM2500 • Safety/avoided conditions during washing: hot components, braking, loading

💭 Think About

• Think about which part of the engine you are trying to clean during an off-line water wash and how airflow path and area affect washing coverage. • Consider whether the engine should be producing power, coasting, or just being rotated for a cleaning wash, and why. • Ask yourself what engine features can be adjusted to let water reach more of the fouled compressor surfaces without risking damage.

✅ Before You Answer

• Verify which component (compressor vs. power turbine) actually benefits most from an off-line water wash. • Check which actions are explicitly avoided in washing procedures: using brakes, washing when hot, or approaching idle power. • Confirm which control (speed vs. stator vane position) most directly increases the exposed flow area for the wash water through the compressor.
