Abstract

fetched live from OpenAlex

The ground effect on the lift and drag forces and vortices generated by a slender reverse delta wing with different anhedrals was investigated experimentally. The study was inspired by the Lippisch-type RFB X-114 WIG (wing-in-ground effect) craft for which a reverse delta wing planform with anhedral was employed. The results show that, by positioning the trailing edges of the anhedraled reverse delta wing parallel to the ground, the lift and drag coefficients were found to increase persistently with increasing anhedral as the ground was approached (for ground distances within 40% chord). The observed lift augmentation was also accompanied by an ever-increasing rotational speed and total circulation of the vortices generated by the anhedraled wing. The vortices were also found to be displaced more outboard as the ground was approached, which further suggests their little relevance to the lift generation of the anhedraled reverse delta wing.

Teacher imitation

Not 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.
