摘要
民用航空发动机部件在使用中不可避免的退化是导致其整机性能衰减的最主要因素。本文阐述了引发发动机机械部件退化的多种机制及其各自对发动机性能产生的影响。发动机清洗作为一种最为经济、有效的性能维持方法,已被业界广泛采用,各种可能提高发动机清洗效率的设计相继应用于民用航空发动机的性能维护中。
Engine components deterioration appears to be the main reason of engine performance degradation. Common mechanisms which may lead to engine components deterioration have been introduced to gain the various effects on engine performance. Civil aero engine off-line compressor washing is widely regarded as the cheapest method for engine maintenance and a series of investigations have been carried out for the engine performance retention.
