SELECTED WORK / EVIDENCE FIRST

A FAILED DRIVE SYSTEM.
A BETTER FINAL DESIGN.

AeroVolt began as a belt-driven horizontal-axis turbine. Excess friction consumed the available torque, while reducing belt tension enough to free the system risked slip. With testing time running out, I converted the generator to direct drive and the team recorded the highest electrical output in the class.

CASE STUDY / 01

AeroVolt Competitive Wind Turbine

I helped design and build this 3D-printed horizontal-axis wind turbine around a carbon-fiber shaft, sealed bearings, a 12 V DC motor, and NACA-inspired blade geometry.

What I contributed +

I designed custom printed components and prepared engineering drawings.
I sliced, printed, assembled, and troubleshot the physical mechanism.
I supported purchasing, budgeting, calculations, planning, and documentation.
When the belt drive failed, I proposed and completed the direct-drive conversion within the remaining test window.

CASE STUDY / 02 · MECH 220

SureShift Five-Speed Transmission

I co-designed four forward ratios and reverse for an NCC test stand, using printed PLA gears, stainless shafts, bearings, and a forked shifting architecture.

Contribution

I authored every drawing in the 18-page packet and co-designed the gears and shaft spacing.

Build

I co-led printing, assembly, alignment, fitting, and late-night troubleshooting.

Result

My team was one of two to earn full mechanism credit after extensive print and fit iteration.

Final tested ratios: R 1:1 · 1st 4:1 · 2nd 2:1 · 3rd 1:2 · 4th 1:4. The schematic preserves the vertically stacked bottom input → sliding middle selector → top output architecture, with tangent pitch contact in every position. Reverse uses the forked carrier and two intermediate gears on separate prongs. Prototype efficiency measured 80.00–85.71%.
