Wind / Optimizing Blades on CD Wind Turbine
« Last post by true27182 on April 03, 2024, 06:43:48 PM »I have been attempting to optimize the amount of voltage that can be generated from a CD Wind Turbine with a Lasko 20-inch 3-Speed Box Fan to spin the blades on all three speed settings. The blades that I am currently using are 13.5 cm long, and 4 cm at the base and 2.5 cm at the tip, with a very small curve (around 1-5 degrees). So far, I have managed to generate the greatest amount of voltage (around 2.5 volts) with a two blade setup.
From here, is there anything I could do to improve the design of the airfoil to generate more voltage? I know that longer blades tend to perform better than shorter ones (I'm planning to increase the length of the blades to around 17.5 cm for the next design), but how should I change the width and/or the curve of the blade for better performance on all three voltages?
