Abstract

The present work is concerned with the design of an improved turbine blade which reduces the aeroelastic effect and increases the output torque. The NPS100 rotor is taken as the baseline blade and modelled in NuMAD. The rotor is analysed for actual wind load computed using the Blade Element Momentum theory and an improved design of the NPS100 is suggested having different aerofoil profiles throughout the span. The effect of aero-elasticity on the output power generation is studied and a method to minimize the aeroelastic coupling is proposed.
