  3. 2. Performance analysis of a small-scalewind turbine at variable pitch and withpitch unbalance

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Francesco Mazzeo; [2021]
    Keywords : Wind energy; wind turbine; pitch angle; pitch unbalance; Blade Element Momentum BEM theory; Computational Fluid Dynamics CFD ; wind tunnel experiments; oscillations;

    Abstract : When it comes to design a wind turbine rotor, several parameters have to be taken into account. The present work focuses on the inclination of the blades with respect to the rotor plane, namely the pich angle. READ MORE

  4. 3. Analysis and Initial Optimization of The Propeller Design for Small, Hybrid-Electric Propeller Aircraft

    University essay from KTH/Flygdynamik

    Author : Ali Alshahrani; [2020]
    Keywords : Electric; hybrid; Propeller; Optimization; variable pitch; fixed pitch; blades number; Eldrivet; hybrid; Propeller; Optimering; justerbar vinkel; fast vinkel; bladnummer;

    Abstract : This thesis focuses on the optimization of the electric aircraft propeller in order to increaseflight performance. Electric aircraft have limited energy, particularly the electricmotor torque compared to the fuel engine torque. For that, redesign of the propeller forelectric aircraft is important in order to improve the propeller efficiency. READ MORE
