Design Studies

Three additional personal studies: an opposed-output gearbox, a stepper-motor-powered rising platform, and an exploratory concept UAV.

COMPLETED · 3D-PRINTED PROTOTYPE

Opposed-Output Gearbox

A gearbox that transfers rotation from one input shaft to two output shafts rotating in opposite directions, with a removable housing and an internal gear train. I designed the shaft arrangement, the removable housing, and the sectioned view used to review the internal gear layout. The completed design was 3D-printed and built as a prototype, and it worked well.

Isometric CAD render of a hexagonal prism-shaped housing on a slate background, with a cylindrical shaft protruding vertically from the center of the top face and two smaller round shaft stubs protruding horizontally from two side faces at different heights; small fastener-slot details line the top edges. — Exterior view of the gearbox housing.

Isometric CAD render of the same hexagonal housing with its upper portion cut away in section: a three-pronged triangular internal bracket is shown with a diagonal cross-hatched pink section-cut fill, with angled gear-tooth geometry and a central round bore opening visible below the cut. — Sectioned internal view showing the gear train.

COMPLETED · 3D-PRINTED PROTOTYPE

Rising Platform

A stepper-motor-powered rising platform. I designed it in CAD, 3D-printed and built it, and it operated as intended.

Isometric CAD render of a mechanical lift platform on a slate background: a flat square platform with a raised oval pad sits atop an angled bracket connected to diagonal cross-braced linkage arms, above two parallel vertical rail guides leading down to a base plate, with a separate L-shaped bracket housing beside the rails. — Isometric view: the platform elevated, with the mechanism exposed.

Front orthographic CAD render of the same lift mechanism: a horizontal plate sits at the top above a compact housing with screw-hole details and an internal X-shaped brace pattern, with two long parallel vertical members showing a helical surface texture running down to the base and a shorter plain vertical bar centered between them. — Front view: the paired rack geometry and internal gear interface.

EXPLORATORY CONCEPT · NOT BUILT

Exploratory Concept UAV

A personal, exploratory flying-wing UAV aimed at longer range and more cost-efficient design. I designed it in CAD and analyzed it in CFD with my own OpenFOAM® simulation GUI. It has not yet been built or flight-tested, and is separate from the completed, flight-tested capstone aircraft.

Isometric CAD render of a tailless flying-wing aircraft on a slate background: each wing sweeps back and tapers to a point, with a semi-transparent dark-gray skin revealing an internal tan diagonal rib and truss structure beneath it; a small white vertical fin sits at the rear of the center fuselage pod, which has a clear rounded bubble canopy at the front.

Top-down orthographic CAD render of the same flying-wing aircraft, symmetric left-right, with both wing panels sweeping outward and back from the central fuselage pod; a small white vertical fin projects above the pod at the rear centerline and the clear bubble-canopy nose is visible at the front, with the internal tan truss structure again visible beneath the translucent wing skin.

Isometric CAD render of the same flying-wing aircraft from a different oblique angle, more end-on along the span, with one wing swept toward the viewer in the foreground and the other receding into the background; the internal tan truss structure is visible through the translucent wing skin, and the white vertical fin and bubble-canopy pod sit mid-frame.
