Optimizing blade design for small-scale wind turbines: a comparative study of 4-blade and 6-blade prototypes

This research investigates the voltage performance of small-scale wind turbine prototypes with varying blade configurations and distances from a wind source. Using simple, cost-effective materials, 4-blade and 6-blade turbine models were constructed and tested under controlled conditions using a hair dryer as a consistent wind source. Voltage outputs were measured using a multimeter, and results show that both blade count and distance from the wind source significantly influence electricity generation. The study offers insights into the design optimization of wind turbine blades for renewable energy education and small-scale applications.
