美国海军飞机发动机异物损伤研究

异物损伤是飞机发动机受损的重要原因，备受美国海军重视。发动机异物损伤原因的准确判别具有难度，经常需要有经验人员根据损伤结果进行推测。异物存在、吸入条件和作业环境是影响发动机异物损伤的三方面因素。改进飞机设计、开展异物排查可减少异物损伤的发生。

Research on FOD of US naval aircraft engine

Foreign object damage (FOD) is the critical cause for the failure of naval aircraft engines. It is difficult to validate the exact causes for FOD, therefore experts sometimes deduce the causes by examining the FOD characteristics. Foreign object, ingestion process and operating environment are key factors which influence the FOD of aircraft engines. The FOD can be decreased by Improving the aircraft design or cleaning the foreign debris timely.
