Abstract
The focus of the present study is to develop an Artificial Neural Network (ANN) model to predict the unsteady lift coefficients of an ellipsoidal airfoil in LowReynolds-Number (LRN) flapping motion. Computational Fluid Dynamics (CFD) simulations of the flow around the airfoil flapping in the form of a novel figure-eight pattern are conducted. The corresponding unsteady lift coefficients are used for the ANN training and validation of its predictions. The results show that the ANN is capable of predicting the lift coefficients with reasonable accuracy, and it can be used to obtain the effects of unsteady flow and system parameters, pitching amplitude of oscillation and Reynolds number, on the aerodynamic performance.

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
