ConclusionIn the beginning of this project, we had very high hopes. There were a lot of different aspects we hoped to expand upon from the previous group, and a lot of interesting ideas we wanted to implement. Unfortunately, due to the budget constraints halting the installation of the turbine outside, and the loss of much of the previous teams work, many of these ideas were not realized. However, we are happy that we have provided a more professional and useable test-bed for the turbine, as well as a RPM sensor that may be used for a plethora of different projects in the future. Our only objective that we expected to deliver upon and failed was the full utilization of available wind power. Throughout this semester, many different solutions for this problem were brought up, but each of them failed to accomplish what we wanted. The final idea of simulating pitch control through the software interface is one that we are confident will work, but bugs in the design of the control as well as time constraints on designing and testing it have made it impossible to complete. All of this being said, our group wishes to thank Zhongjian Kang, Lee Harker, and Dr. Ajjarapu for all their help and support throughout the project.
