This study was conducted on the design of large wind power blades. The target blade is 20 MW class. After performing an aerodynamic design, it was verified through aerodynamic analysis. Structural loads were also calculated after aerodynamic design. A skin-spar structure was adopted as the structural design results were investigated for safety through structural analysis. The structural configuration. The structural design results were confirmed through laminate optimization of the spar flange and web. The final structural design result was analyzed as being safe.
