Experimental study of the vortex flow and aerodynamic characteristics of a reverse delta wing
Bibliographic record
Abstract
The vortex and aerodynamic characteristics of a reverse delta wing (RDW) were investigated by using particle image velocimetry (PIV) in conjunction with flow visualization and force balance measurements. The RDW had a delayed stall but a lower lift and drag compared to the regular delta wing. The stalling mechanism of RDW was triggered by the breakdown of the multiple spanwise vortex filaments developed over its upper wing surface. The RDW vortex was found to be located outside the wing, and vortex rollup was completed at x/ c = 0.7. The PIV crossflow measurements were also used to compute the lift coefficient. Finally, depending on angle of attack, the RDW vortex can remain concentrated and axisymmetric or resemble a circulation-like flow with patches of vorticity.

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.
