N. BLATTNER
Aerospace Engineer

Building things that fly, orbit, burn, and learn.

M.Sc. Aerospace Engineering at the University of Stuttgart, graduating September 2026. My work spans air- and spacecraft structures, rocket propulsion, computer science, data science and machine learning, and a decade of hands-on builds. This site walks through the actual process of designing, simulating, building, testing and optimizing to realize various projects.

2D CFD Framework for Interactive Flow Simulation

A from-scratch 2D flow solver with a live, interactive viewer: a vectorized D2Q9 Lattice-Boltzmann core in pure Python/numpy, validated against analytic and benchmark solutions, fast enough to draw obstacles with the mouse and watch a Kármán vortex street form in real time.

Custom 2D Airfoil Design Code

An inverse 2D airfoil design tool: prescribe the velocity distribution and get the geometry plus its full polar — exact potential-flow core, integral boundary-layer analysis with transition prediction, and an interactive GUI. Prototyped in Python, final version in C++.

Y4 Coaxial Multirotor Configuration

A 3D-printed Y4 multirotor: tricopter geometry with a coaxial rear motor pair instead of a yaw servo. Custom motor mixer, thrust-stand-derived yaw linearisation, and a deliberate motor-out flight test — Ardupilot-based flight control throughout.

Foam & Fiberglass Fixed-Wing Platform

Fixed-wing aircraft constructed using conventional foam core and hand-laid fiberglass technique. Balance between light weight, durability, and ease of repair.

3D-Printed Aircraft: From Spitfire to Bf 109

Two fully 3D-printed RC warbirds: a thin-walled Spitfire that proved too heavy and crashed after twenty wobbly metres, and a Messerschmitt Bf 109 redesigned around an internal spine structure — light enough to actually fly.

Mostly 3D-Printed CNC Machine, Rebuilt for Real Tolerance

A self-built CNC router whose structure was largely 3D-printed, then redesigned after the first version flexed under load — stiffer printed parts, metal where printing could not hold tolerance, and a rebuilt gantry that finally cut accurately in wood and aluminium.

Modernizing the Horten H3 Airfoil

Full inverse redesign of the 1938 Horten H3 flying-wing airfoil: same pitching moment for unchanged trim and stability, ~10% less drag in the laminar bucket, a soft stall instead of a hard one — validated with CFD and converted into a glide-polar improvement.

Design and Implementation of a VTOL UAV with Flight Transition Optimisation

University project: an experimental tilt-rotor UAV blending multirotor vertical takeoff with fixed-wing forward-flight efficiency — structural, propulsion and aerodynamic design in CATIA, with a servo-driven rotor tilt mechanism and the flight mechanics of the transition itself as the design driver.

Who I Am

Aerospace by training, hands-on by habit

I am finishing my M.Sc. in Aerospace Engineering at the University of Stuttgart, closing it out with a thesis at Airbus Defence and Space. Before that: two years as a working student and development engineer at Diehl Defence on solid rocket motors and jet-engine CFD, and a semester at EPFL working on cubesat structures.

Outside of coursework and work, I build things end to end — from a computer-vision aircraft tracker running on phone cameras, to RC aircraft and a from-scratch VTOL UAV, to a 3D-printed CNC machine I redesigned to hold real tolerance. I like the part of engineering where a plan meets a workshop and turns out to be wrong in an interesting way.

Looking for my first full-time role

I am looking for a graduate or entry-level engineering position from autumn 2026 — ideally somewhere the work involves simulation, propulsion, structures or the software that supports them, and where things get built and tested rather than only modelled. Based in southern Germany, open to relocating.
