Ground effect on the aerodynamics of a naca 0015 airfoil with a plain trailing-edge flap
Bibliographic record
Abstract
The ground effect on the aerodynamics of a NACA 0015 airfoil with a plain trailing-edge flap was investigated experimentally at Re =1.61*105. The ground proximity led to an increased lift and nose-down pitching moment compared to their out-of-the-ground effect counterparts. The flap deployment also caused the flow separation to move further upstream, rendering to an earlier stall as the ground was approached. The amount of lift increment was, however, found to be most significant at low angles of attack and was reduced with increasing trailing-edge flap deflection. Meanwhile, the pressure drag of the flapped airfoil was reduced in ground effect. The enhanced aerodynamics of the flapped airfoil, especially in close ground proximity can greatly benefit the take-off and landing of WIG (wing-in-ground effect) craft.

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.
