The manuscript is being written and will appear here once the wind tunnel validation campaign is complete.

Overview

What this is about

This project optimizes tailfin (vertical stabilizer) planform geometry for low Reynolds number flight (Re ≈ 50k–100k) through a closed loop that connects parametric CAD, transition-modelled OpenFOAM, a machine-learning surrogate with a Pareto search, and wind tunnel validation. The first three stages are complete, and the headline result is an optimized fin that buys roughly 40% more directional stability for about 14% more drag versus an RQ-11 Raven style baseline.
