What are the key aerodynamic challenges in wind power machine development?The paper identifies rotor dynamics as a crucial area, highlighting the interaction of inertial, elastic, and aerodynamic forces affecting manufacture and operation. Aeroelasticity remains a significant challenge in transferring technology from aircraft to wind power applications.How does the efficiency of the Savonius rotor compare to conventional rotors?The Savonius rotor achieves a maximum efficiency of around 31%, significantly lower than conventional rotor designs. Additionally, it requires 30 times more surface area for the same output, making it less economical for large power generation.What types of wind-driven machines are identified in the text?Wind-driven machines are classified as Wind-Axis Machines, which rotate parallel to wind direction, and Cross Wind-Axis Machines, which rotate perpendicular to the wind. This classification aids in understanding their operational principles and potential applications.
