    OverviewEngineering CalculationsRegional ConsiderationsTechnical SpecificationsEstimated CostsCommon MistakesOther DesignsThe intent of this project, created in collaboration with Mech425, is to identify the best angle for flat, uniform blades in relationship to the air stream. The angle of the blades should be optimized to convert the most amount of energy into rotational motion. Flat blades are used in conjunction with vertical axis turbines and the design is generally selected when simplicity is preferred or when access to tools and supplies are limited. 1See more on appropedia.org
