Projects

Analyses, CAD models and numerical work. For each project I explain how I did the calculations and what came out of them.

Metal wing structure

A team project: a semi-monocoque metal wing with a torsion box in the nose. I was responsible for the assembly model in Siemens NX and for how it would be made. I designed the sheet parts as bent parts in the Sheet Metal module, and chose the rest so it could be bought from a supplier.

Propeller Aerodynamic Analysis — BEMT + CFD

Aerodynamic analysis of a two-blade propeller. I computed its performance with blade element momentum theory (BEMT) in my own Python script and checked it against CFD simulations in Ansys Fluent (MRF, k-ω SST).

Fan drive transmission system

Course project for Machine Design Fundamentals at Warsaw University of Technology. A belt-driven fan drive: motor and V-belt selection, shaft strength calculations, bearing selection and frame analysis, plus a full set of manufacturing drawings and a 3D assembly model.

Numerical modelling of methane combustion

Three Python solvers for methane–air combustion, written from scratch without a kinetics library: adiabatic flame temperature (Newton–Raphson), 0D reactor ignition (RK4) and a 1D laminar flame profile (finite differences, Newton and the Thomas algorithm).
