现代航空发动机设计是基于知识的设计,知识分类与获取是航空发动机设计知识管理的起点,也是难点.实施知识获取技术能够使得设计知识有效积累,推动设计知识管理实施,从而真正实现基于知识的设计,提高航空发动机设计水平.分析了航空发动机设计过程、航空发动机结构,提出了航空发动机设计知识分类方法、知识获取策略与获取方法,进一步探讨了数据挖掘与知识发现技术.%Modern aeroengine design is one based on knowledge. Classification and acquisition of design knowledge is a key to successful implement of knowledge management for aeroengine design. It helps to accumulate design knowledge effectively, to push the plan of design knowledge management, to realize aeroengine design based on knowledge management to implement knowledge acquisition for aeroengine design. Consequently, this would advance the design capability for aeroengine. The knowledge of aeroengine design, which include the structure and design process of aeroengine, are analyzed. The classification method of aeroengine design knowledge, the strategy and method of design knowledge acquisition are drawn out. Data mining and knowledge discovery in database are discussed.
