Aeronautical Engineer Intern @ Soaring Aerospace
Propulsion and thrust testing
I selected replacement lifter and tractor motors, ESCs and propellers for two lift-class multirotors and a third aircraft in preliminary design. I sized the candidates with kV and max-power hand calcs and blade-element / momentum theory, then verified them on a thrust stand, using FEA-checked blade hubs and an adjustable fixed-pitch mount I designed to fit virtually any candidate motor. My selection cut the heavier (50 lb lift) UAV's propulsion cost by about 88 % while it met its required performance targets. When the lighter (25 lb lift) UAV's original motors could no longer be imported into the US, the replacement motors I sourced kept it at its required performance targets.

~88 %lower propulsion cost (heavier UAV, 50 lb lift)
In a cooling-fan trade study I tested two 3D-printed fan concepts, and the better one lowered the motor's steady-state temperature by about 20 % at 50 % throttle.
Structures and FEA
I set up a two-pass FEA method to find failure points in a new airframe's preliminary structure, and redesigned a folding-arm joint.
CAD mass model and API scripting
I scripted the Onshape API to audit part masses until a production UAV's CAD mass model matched the measured aircraft, then extracted its CG and inertia for flight-dynamics modeling.
3D-scan reverse engineering
I rebuilt a rotor blade from a 3D scan (EinScan, Solid Edge) into CAD so its airfoil sections could be extracted for CFD.
Root cause analysis
For a yaw-instability root cause analysis (RCA), I wrote log-analysis scripts that surfaced a command-scaling mismatch between flight-controller output and ESC input, and analyzed data in real time during tethered flight tests.
