Tail Buffet of F/A-18 at High Incidence with Sideslip and Roll (Part 1)
Bibliographic record
Abstract
The unsteady pressure was measured simultaneously at 24 locations on both sides of a vertical e n of a rigid, 6% scale model of the F/A-18 aircraft in a wind tunnel. This pressure was integrated over the entire e n surface and over time to provide the mean and rms normal force, bending moment, and torsional moment on the e n in order to determine its buffet loading. Results are available for Mach numbers M =0.25, 0.60, and 0.80; angles of attack ®=25, 30, and 32.5 deg; and a sideslip angle i 15 deg < ¯ < 15 deg or a roll angle i 30 deg < ‐ ’ < 30 deg. At zero roll and sideslip the mean force and moment coefe cients generally increased with increasing angle of attack; but as the sideslip or roll angles increased some coefe cients changed sign, and their relationships to ® became more complex. A measurable trend of the mean force coefe cient to decrease with increasing Mach number was also observed. The rms normal force coefe cient increased signie cantly as ® increased from 25 to 32.5 deg, but showed no appreciable trends as the Mach number increased from 0.25 to 0.80. The wind-tunnel tests are complemented by a e ow-visualization study of the leading-edge extensions vortices of a 1:48 scale model of the F/A-18 in a water tunnel, showing the vortex burst locations at different aircraft orientations. Part 2 of this study presents statistical results of the forces and moments.

How this classification was reachedexpand
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.
