Abstract
Morphing blades wind turbines are getting more attention nowadays because of its benefit in reducing blade loads and improving aerodynamic performance. A new passive morphing forward-folding blades wind turbine inspired by the Borneo Camphor seed is proposed. To understand the new phenomena caused by these new morphing blades wind turbine design, the analytical method was used. A preliminary study was conducted using analytical software QBlade to predict the power performance of the proposed forward-folding blades wind turbine. The performance of the inspired morphing forward-folding blades wind turbine was compared with a flat span rigid blades wind turbine. All wind turbines tested in this study have the airfoil sections of SD8000 but different fold angles. The QBlade is a software which integrated the airfoil design and analysis software XFLR5 and XFoil, airfoil polar extrapolation software, blade design aerodynamic and structural software, Blade Element Momentum (BEM) model simulation software, together with aeroelastic simulation from FAST software. These integrated models in the QBlade allow the prediction of the performance of the inspired morphing forward-folding blades wind turbine. The predicted results showed that given the same geometry of the blades, the forward folding of blades changes the power coefficient, CP, thrust coefficient, CT, and operating tip speed ratios at given wind speed. This preliminary study demonstrated the potential of the morphing forward-folding blades wind turbine in reducing the cost of wind power.
