摘要
航空发动机的健康状况直接影响飞行安全。为了保证飞行安全、缩短再次出动准备时间、提高装备的完好率,结合航空发动机机务维护的特点,介绍了基于数据库开发实现发动机地面专家诊断系统的设计方案,提出了按知识点分类的方法构建知识库,降低了构建知识库的难度,缩小了诊断范围,提高了故障诊断成功率。
The situation of aero-engine directly influences flight safety. In order to ensure flight safety, shorten between-flight preparation time and improve equipment intactness ratio, a design plan is built to realize expert system diagnosis based on database development according to the characteristics of aero-engine maintenance. The knowledge base is formed by categorizing knowledge points. It decreases the difficulty of data establishment, shortens the scope for failure diagnosis and improves the efficiency of failure diagnosis.
