| Abstract | ||||
| The paper deals with the detailed aerodynamic design and performance as well as the calculation of the energy-output of a three-bladed propeller-type rotor of a 10 to 20 kW wind machine. The aimed-at wind machine is designed to best suit manufacturing technologies and wind energy climat-ology of Egypt. The in-hand detailed information, obtained through a comprehensive survey and evaluation process reported by the present author in two preceding published works, in addition to the results of a series of computer-runs carried-out to evaluate the performance of a number of internationally successful wind-machine rotors, have been used to determine the geometric and the aerodynamic parameters of the rotor-design Al. The rotor is designed to operate, when adjusted at the determined performance-setting (speed of rotation & blade pitching angle), at four possible options having rated power of 10, 12.5, 16 and 20 kW; each of them best suits a correspon-ding annual-average wind-speed level. The computer code used in the design is an addition to the Rockwell-International program to give it the full advantages of use on a modern personal computer. | ||||
