Abstract
A free vortex wake based C++ aerodynamics library, LibAero, has been initially developed in previous work. The library is aimed towards wind turbine performance prediction for an arbitrary blade shape and for use in a Multi-Disciplinary Design Optimization (MDO) tool. The model is based on a Weissinger lifting-line approximation, and uses vortex particles, filaments and quadrilateral sheets for the wake discretization. A new implicit vortex advection method is implemented, and its accuracy and stability is analyzed compared with the explicit method. It is found that the implicit method exhibits much better convergence behaviour. A set of validation cases using experimental data from the MEXICO experiment is provided.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
