I study mechanical engineering at TU Eindhoven. Alongside my studies I design hardware at Clearwings, a start-up converting existing aircraft to battery-electric propulsion, and work as a research assistant in the university’s wind tunnel lab.

Hardware for an electric-aircraft retrofit.

Clearwings converts existing aircraft to battery-electric propulsion, starting with a Cessna 150. I design mechanical parts for the retrofit and take them from CAD through prototypes to manufactured hardware — among them the aircraft’s cockpit panel and a battery module.

Research in the university’s wind tunnel.

In the TU/e Wind Tunnel Laboratory I support experiments and test campaigns. My main project so far: bringing a 1995 six-component force balance back into service — finding faults, calibrating it and analysing the data.

A four-metre wind tunnel, built from scratch.

Designed in SolidWorks and built by hand in the school workshop: an open-circuit low-speed tunnel with a 30 × 30 cm transparent test section and a self-built force balance — used to measure how flap deployment shifts the stall point of a Boeing 737-NG-style wing.

About

I fell in love with aviation in high school — it’s just amazing to see things fly. So I built a wind tunnel to find out how it works. Today I study mechanical engineering at TU Eindhoven, work in the university’s wind tunnel lab, and help make aircraft electric at Clearwings.
