Open in new tab After the completion of our final prototype design, the group made a presentation to the entire class on how we fulfilled the requirements set out by the course. We discussed the four customer needs (durability, power generation, aesthetic appeal, and unique features), and provided evidence of how we satisfied each one.
Final Design
Through concept generation and selection processes, our group settled on several features which we wanted to see in the final turbine design. These included three 3D printed blades, a 3D printed base, an input gearbox, and a magnetic braking system. As the group member with the most experience in CAD and 3D printing, I bore most of the responsibility for the design of the final prototype. The COVID-19 pandemic meant that we would not be able to physically build our turbine, but I still kept the design grounded in the reality of manufacturing. All the components which are not readily available (screws, motors, etc.) can be either 3D printed or machined with relative ease. After the design was completed, we estimated that the turbine could produce at least 0.57 W of power and withstand wind speeds up to 20 m/s if not higher.
Proposal Presentation

As part of the development process, we were required to give the professor and TAs a presentation on our plan for the final turbine design. This discussed why we chose the features that we did, and also covered how we arrived at those ideas in the first place. We also discussed other potential concepts which were not selected, as well as the potential application for our wind turbine. We had chosen Kouba Olanga, Chad, as the region had high wind speeds and appallingly low access to electrical power.

This document largely covers the same material as the presentation discussed above. However, it was given in the form of a professional proposal, and also required a detailed set of engineering drawings of the selected concepts to go with it.
