This is a 2 or 3 blade design in the Savonius style. The material we selected to use a satin weave carbon fiber that will be laid over a 3D rendering of our design. ● Electrical- The purpose of the wind turbine is to produce electricity and there is a complete setup required for this purpose. Including generator, inverter, control system, and other electric circuits accessories including wires, capacitors, resistors, and rectifiers. The wind will just rotate the blades and a mechanical mechanism is required to extract the energy from blades rotation. Similarly, the electrical critical section is important for producing electricity from mechanical energy. ● Data Acquisition- A system that is sampling signals which measure the acoustic emission of the turbine. The purpose is to acquire and store the acoustic data. ○ Includes: data acquisition, data logger, preamp, microphone, computer software 3D Blade Design: 13 Figure 2: (a) 3 blades without end caps; (b) 2 blades with end caps Fig 3.
