Abstract

fetched live from OpenAlex

The effects of upward ramp rate, actuation start time, and duration of a moveable trailing-edge flap on the critical aerodynamic values of an oscillating wing were investigated. The largest improvement in the peak negative pitching moment was obtained with a fast ramp rate and a start time near the mean angle. The largest value of net work coefficient, however, was generated with a delayed start time and a slower ramp rate. The peak lift coefficient decreased with increasing ramp rate and decreasing start time. The inclusion of a short steady-state portion in the flap motion was beneficial. An upward flap deflection initiated slightly after the mean angle during pitch-up, moved to its maximum deflection at a moderate speed, remained steady for a rather short period, and then returned to its initial position, which spanned half the oscillation cycle, was found to provide a best compromise between the various aerodynamic requirements.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

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.
