Abstract�� To solve the multidisciplinary problem of flutter wing model designing for low-speed wind tunnel test, which there is lots of difficulty in and expended abundant time conventionally, a design method named genetic/sensitivity-based hybrid algorithm was applied, which has very well global and local search capabilities and optimization efficiency. The theory, process and applicability of genetic/sensitivity-based hybrid algorithm were presented. The math model, based on real physical one, was modeled according the essential theory and design course of the flutter wing model designing. With the method using in design, not only the time of model designing is reduced to a great extent, but also the design precision is assured, for the error comparing result and target of model design can reach below 5% relatively. An optimization method of flutterwing model was developed and was used in many aspects of model designing, providing an efficient design method in engineering.
