Abstract：In order to improve aerocraft’s ground test efficiency, an aerocraft ground test evaluation system based on test modeling was developed. The system had two procedures, test modeling and relevance evaluation. In view of six test elements including experiment demand and goals, assignment, procedures, resources, facility and results, research on modeling technology based on UML mechanism was carried out，and the modeling tools was RationalRose, an object-oriented visual modeling tool of Rational companies in the United States. According to three evaluation methods as spider net evaluation, gray relative analysis and reference evaluation, application of the test model is studied, and the better test plan was selected by comparing the evaluation index. Combined with an aircraft ground ignition test scheme, the application of test evaluation system based on the ground ignition test modeling was constructed. Around the test process, method, data and so on, the application was verified and good results were achieved.
