Abstract
Our goal was to find expected pressure around different wingtip shapes to predict vortice behavior. This project focused on aerodynamics, specifically the location where high and low-pressure air mixes over a lifting surface. High-pressure air mixes with the low-pressure air at the wingtip of a plane creating vortices that cause drag, which wastes fuel and slows down the aircraft. Not only is this bad for the environment, but it increases the cost of flight and affects the distance that larger planes can fly ahead of smaller planes due to wake turbulence. As planes have gotten lighter, faster, and safer, the issue of wingtip vortices and drag has continued to be a problem. The approach we used to answer this problem was to select an applicable data set using continuous machine learning models and later, discrete models to predict a pressure coefficient above the wing. We combined multiple datasets from the same research paper created by NASA to have numerous factors for the machine learning model to predict. As a result, we produced accurate static pressure predictions with 80% to 90% accuracy. Even more accurate were our model recall scores which were within 99%. As a result of the work done on this project, accurate predictions of expected pressure over an airfoil are achievable. With only a few input variables about speed and dimensions, an accurate static pressure can be found.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
