A composite rotor blade structure optimization design approach based on parametric module definition is presented to improve design efficiency for engineering application. By taking a C-spar composite rotor blade as the research object, both the profile and the overall structure optimization models are built based on parametric module definition. By using the results of the profile optimization, the initial values of the overall structure optimization model are obtained. Then, the overall structure optimization is implemented to obtain the best blade structure. A case study is performed. The results demonstrate that the proposed method can complete the structure design of composite rotor blades efficiently.
