Abstract: On the basis of analyzing characteristic data of an aeroengine test, the data management using engineering database is studied. This paper also analyzes the E-R model for aeroengine test engineering database, the structure of aeroengine test engineering database, the interface of the data processing program with the aeroengine test engineering database,and the development of client module. The development of engineering database for aeroengine test has improved the efficiency of aeroengine test and ensured veracity and security of aeroengine test.
