This study aims to analyze the manufacturing and structural performance of a helical vertical-axis wind turbine blade.
Manufactured a 5 kW fibreglass helical vertical-axis wind turbine blade.
Conducted destructive mechanical testing to assess structural performance.
Performed strain measurements to identify strain concentration areas.
Highest strains were recorded on the blade's inner surface along the leading-edge bondline.
Failure initiated at the bondline locations with measured strain below expected material failure strain.
Findings emphasize the importance of bondline design in enhancing the structural integrity of composite blades.
