Abstract: This paper presents the development of an integrated computer
program for blade design of small to medium wind turbine generators. Since the
blade design process is time consuming and recursive, an integrated computer
program with combination of aerodynamic and structural considerations is
developed to make the entire design process faster and more efficient. In this
software package, there are five embedded sub-functions, including an
aerodynamic coefficient generator, an airfoil database, an automatic blade
modeler, a wind flow generator and the performance evaluation under operating
conditions. This is a window based PC program written in visual C language and
designed to cooperate with the commercial CAD and FEA software. The blade
profile can be built automatically once all the design parameters are
specified. Furthermore, intensive aerodynamic analyses of the blade design can
be carried out with the aid of wind flow generator. This integrated computer
program has been employed for the blade design of the laboratory scale 150KW
wind turbine generator to verify its efficacy.
