Abstract
Investigations of nonlinear aeroelasticity of flexible structures subjected to unsteady transonic flows were carried out using a three-dimensional aeroelasticity reduced-order fluid model which is based on the Proper Orthogonal Decomposition (POD). The number of degrees of freedom was reduced from more than 150000 in the full-order model to 200 unknown variables for the reduced-order model (ROM). The dynamic responses of the aeroelastic system, particularly, the wing Limit Cycle Oscillation (LCO) in the transonic regime was simulated. Numerical simulations on the AGARD 445.6 wing show good agreement between the ROM and the original full-order fluid model.

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
