Abstract:

In this paper, data mining techniques are introduced to investigate the test-drlving database of aero-engines. This paper introduces the basic concepts of rough set first and discusses its application in data mining based on the aero-engine test-drlving database characteristics. The rules obtained from the data mining procedure are correct and can provide valuable information for aero-engine tests. The results show that it is feasible to employ data  mining techniques for analyzing the aero-engine test-driving database,
