【 摘 要 】

For a blade runner of a Kaplan turbine, with its 3D geometry obtained through the Photogrammetry technique, the paper aims to determine the following geometric parameters of the blade profile: the stagger angle, the chord length, the relative thickness (maximum thickness / chord length) and relative thickness position, the relative maximum camber and the maximum position of the profile camber, using the following software packages: SolidWorks and Visual Basic for Applications included in Microsoft Excel. The blade profiles are generated through multiple sections of the axial blade runner with coaxial cylinders with the runner axis and plane unfolding. These parameters will be compared with the corresponding design parameters in order to investigate the precision of the Photogrammetry technique.
