Dynamic Adjustment of Engine Washing Interval Based on Aircraft Performance Monitoring
At present,fixed-interval engine washing is commonly used in civil aviation industry to restore engine performance,reduce engine fuel consumption and increase exhaust gas temperature margin.However,the specific operation conditions of each aircraft engine are different,and the performance decline and recovery time are also different.If a fixed washing interval is used,it will be difficult to take advantage of the fuel-saving improvement effect brought by engine washing.According to the aircraft performance monitoring results and exhaust gas temperature margin and other parameters,Airlines A makes a comprehensive evaluation,dynamically adjusts the engine washing interval,shifts from the fixed interval washing mode to the condition-based washing mode,and arranges the washing work again when the engine performance returns to pre-washing level,so that the engine can maintain a lower fuel consumption level.
