Why
Outcome
The project connected aerodynamic choices, structural analysis, and measured power output in a tightly constrained physical build.
Key evidence

Process 01
Tower design
The tower had to fit a 17 cubic-inch volume limit, place the rotor hub at the required height, and print as two pieces within the available machine envelope. SolidWorks lofts, a high-area-moment cross section, and FEA-guided material removal produced a light, printable structure that remained stiff under load.

Process 02
Blade design and testing
NACA 4424 and NACA 63-415 profiles informed the blade geometry. The finished turbine was tested at approximately 25 mph while voltage, current, power, rotational speed, and tower deflection were measured and compared with simulation results.
