Research on the Aerodynamic Load Experiment of MW Blade Model

MW wind turbine blades usually are destroyed by the aerodynamic load. However, measure the aerodynamic load is always difficult. The outside in-truck test method is used for the 100W wind generator sets experiments in power characteristics on the 1MW and 2MW blade models combined the design parameter and the aerodynamic parameters, the experiment results were analyzed. Meanwhile, the aerodynamic load experiment is done for 1MW and 2MW blade models by using the technology of strain measuring; the result of aerodynamic load experiment is obtained. The relationship between aerodynamic load characteristics and blade model parameters is get by analysis and research. The experiment results showed that the outside in-truck test method and strain gauges testing technology are feasible and effective measure on the research of aerodynamic load characteristics, and play an important role on the optimize design of the blades.
