Engineering Portfolio
A record of aerodynamics, flight systems, structural and dynamic analysis, and hands-on design and manufacturing — from CFD and finite element models to physical hardware that actually flew, launched, or got put through real testing.
01 — 06
01
Transient sliding-mesh CFD comparing a conventional DRS flap against Ferrari's 230° "Macarena" mechanism — revealing an aerodynamic airbrake spike during actuation invisible to steady-state analysis alone.
02
Constrained nonlinear optimization of entry, descent, and landing fuel consumption across normal and modified atmospheric conditions using COBYLA and SLSQP in Python.
03
Momentum theory and CFD blade-drag analysis of NASA's Dragonfly octocopter, computing the true hover power needed to fly on Titan and explaining why the mission has to be "charge and hop."
04 — NUStars · NASA Student Launch
In-house manufactured fiberglass airframe and Von Karman nose cone through six vacuum-bagged layup iterations, validated with ANSYS FEA and CFD aerodynamic analysis.
05 — NUStars · NASA Student Launch
Aerodynamic camera housing developed from PDR through a competition flight at Huntsville, AL — capturing in-flight footage that confirmed active drag system actuation for the first time.
06 — Independent Build
Solo design, build, and launch of a 3" fiberglass H-motor rocket — plus a custom altimeter system and 3D-printed nose cone mount added on top of the base kit to record real flight data.
07 — 10
07
FEA and analytical validation of a Cessna 172 wing — combining ANSYS simulation with Euler-Bernoulli beam theory and the Rayleigh-Ritz method to validate tip deflection and stress.
08
Full AGMA-based design of a 70 kW two-stage spur gearbox — three shafts, four gears, six bearings — each sized with a calculated, traceable margin against fatigue and static failure.
09
A finite element beam model validated to under 1% error, combined with acoustic hammer-strike testing, to measure real radial bending stiffness — proving a double-wall rim is roughly 2x stiffer than a single-wall one.
10
Multi-body rigid body dynamics simulation with Euler-Lagrange formulation, impact constraints via Lagrange multipliers, and Hamiltonian energy conservation in Python/Plotly.
11 — 13
11
Wavy-fin modular heat sink in 316L stainless steel designed for binder-jet printing, achieving a 7°C average temperature reduction over a conventional straight-fin baseline.
12
Full product development cycle from needs analysis through topology-optimized FEA, 3D printing in Nylon 12, and ISO 4210 compliance testing across two design iterations.
13 — Independent Design
Purpose-built mechanical device for rolling and storing Marley dance floor — plywood frame, PVC roller, crank mechanism, and locking caster wheel system.
