STL and STEP files of wind turbine rotors: fast three-blade rotor, five-blade rotor and slow multi-blade rotor for water pumping.
Each rotor is computed by Heliciel at the wind speed and tip speed ratio stated on its page, with power and power coefficient.
To create your own custom model and test its performance: Heliciel software
Model designed and computed with the Heliciel software (blade element momentum method, BEM). Design point: 8 m/s wind, 230 rpm (tip speed ratio ≈ 1.5). Slow multi-blade rotor: high starting torque, suited to water pumping.
Model designed and computed with the Heliciel software (blade element momentum method, BEM). Design point: 8 m/s wind, tip speed ratio 6.
Model designed and computed with the Heliciel software (blade element momentum method, BEM). Design point: 8 m/s wind, 611 rpm (tip speed ratio 4). Five blades with rounded tips and 20° skew.
Model designed and computed with the Heliciel software (blade element momentum method, BEM). Design point: 8 m/s wind, tip speed ratio 6. Blades with 15° skew.
