Investigation on Strength and Damage Test of Composite Blade for Vertical Axis Wind Turbine


Article Preview

This work is to design a high efficiency composite vertical axis wind turbine blade which is applicable to relatively low speed region. In the aerodynamic design, the parametric study is carried out to find an optimal aerodynamic configuration having high efficiency in both low and high wind speed region using the proposed design procedure. In the structural design, the blade adopts the skin-spar-foam core sandwich structure concept. The glass fabric/epoxy composite material is used for both skin and spar. The designed configuration is repeatedly modified by structural analysis results using a finite element analysis method. Finally, the strength and damage test of designed blade was conducted. In order to evaluate the test results, it was compared with estimated results. According to comparison results, the estimated results were well agreed with the experimental results.
