Horizontal axis wind turbine rotor design and analysis / Mohd Hafiz Junoh

An innovative horizontal axis wind turbine, (HWAT) which is the rotor blades are attached with springs was designed and fabricated (3 blades HWAT). The project is started with literature review in HWAT scope, in kinematics of spring and also the rotor design which is based on NACA 0020. It is contin...
